Replay: MTG-I2 pre-launch media briefing
On Wednesday 19 August, media representatives were invited to a media briefing ahead of the launch of the next Meteosat Third Generation Imager satellite (MTG-I2). The satellite is set to be launched on an Ariane 6 from Europe’s Spaceport in French Guiana, on 27 August.
MTG-I2 is the third satellite for MTG, completing the MTG constellation. Together the satellites will produce images for weather forecasting in Europe in unprecedented detail. This mission provides new data products and capabilities for European weather services, especially suited to nowcasting of severe weather events.
The MTG-Imager satellites carry two instruments, a Lightning Imager and a Flexible Combined Imager. The Lightning Imager offers completely new capabilities for European meteorological satellites by continuously monitoring for lightning. The Flexible Combined Imager builds a picture of fast-evolving weather systems and can be used to issue timely weather warnings. It is able to scan the entire surface of Earth as viewed from its geostationary position (36 000 km above the equator) in just 10 minutes and can scan Europe and northern Africa every 2.5 minutes.
13 sci-fi books that inspired our favorite shows and movies
The world of science fiction started with the written word, long before it hit the silver screen. Stories of man-made life, Martians, and other marvelous subject matter were being read long before the first sci-fi movie was released in 1902: Georges Méliès' "A Trip to the Moon". Some of these stories became classic tales that have been repeatedly adapted for Hollywood and television, think Mary Shelley's "Frankenstein" and H.G. Wells' "War of the Worlds."
This isn't by any means an exhaustive list but these are the sci-fi books that inspired some of our favorite movies and shows. We have big names like Project Hail Mary and Dune, as well as more obscure titles like the haunting Under the Skin and Stalker. We have included links to the best streaming services to watch each adaptation on right now, but for those of you who are tired of endless subscriptions, we have provided the 4K and Blu-ray releases so you can physically own your favorite media again.

Books are often sidelined in today's visual-obsessed world, but I think they deliver a stronger experience that movies and shows just can't replicate. Now don't get me wrong, I love the movie adaptation of Annihilation, but I have a very special connection to the book. I read it multiple times before the movie release and it made me feel immersed in the inherent weirdness of the natural world and think about how alien our own planet is. The book always came to mind when taking a walk out in the forest and seeing the hypnotic curl of a fern or a bird alighting on a branch inches away from me.
My 5 favorite sights to see in the night sky with binoculars
Beyond simple naked-eye observing, a pair of the best binoculars are the most accessible way to experience the night sky. They are affordable (although pricier models are available), very easy to use compared to telescopes and they offer a wide range of celestial sights, from our solar system neighbors to distant deep-sky objects. They are great for both beginners, casual observers and even veteran stargazers who want to grab a quick look or spend time sweeping through the Milky Way.
So what are the best night-sky targets for binocular users? There are so many, but we’ve done our best to whittle them down to five of the best that provide a good sense of what can be seen through binoculars. We’ve also accounted for different apertures and magnifications to make sure there’s something for everyone, even kids
The moonBinoculars can get you great views of the moon. (Image credit: Getty Images)The moon is the ideal starting point for observing with binoculars. As a large target full of intricate features that appear differently depending upon the illumination, the moon rewards return visits, and you’ll never grow bored.
Even low-magnification, smaller-aperture binoculars will show some interesting details. Small 8x40 or 7x50 binoculars are sufficient; you certainly wouldn’t want to go as low as, say, 8x25 because the moon would appear small. While larger magnifications can improve the view, unless you have the binocular mounted on a tripod, the shake from jittery hands can look like moonquakes. If you don’t have a tripod, an alternate solution is to use image-stabilized (IS) binoculars, where the binoculars’ internal electronics are able to remove the jitter from the image, making the view more static.
The illumination on the moon changes across a 29.5-day cycle as the sun rises and sets over the lunar landscape, with phases cycling from new to first quarter, then to full and last quarter and finally back to new again. Often, the best time to observe a particular feature on the moon is when it is dawn or dusk at that location, and the sun angle is low, casting stark shadows. Otherwise, it is difficult to see the relief when the sun is overhead.
Jupiter’s moonsJupiter and (some) of its moons in orbit. Through binoculars views will be less detailed and smaller, but the moons are still visible. (Image credit: Getty Images)Earth’s moon isn’t the only moon in the solar system that can be seen through binoculars.
A simple pair of 8x40s or 10x50s will be sufficient to watch the four largest moons of Jupiter — Io, Europa, Ganymede and Callisto — circle around the Jovian giant. Unfortunately, these binoculars won’t be enough to show you the belts of Jupiter or its Great Red Spot, but its four large moons, known as the Galilean moons, because they were discovered by Galileo, will appear as pinpricks of light on either side of Jupiter.
It’s fun to follow in Galileo’s footsteps and watch the moons orbiting Jupiter, sometimes disappearing from view as they move behind the giant planet, or pass in front of it. Binoculars will not be powerful enough to show the moons transiting against the face of Jupiter, though — Jupiter is too bright, and the contrast is not great enough. The other 91 moons of Jupiter are far too small and faint to be seen in binoculars.
Mizar and AlcorThe Big Dipper constellation houses the stars Mizar and Alcor. (Image credit: Spike Silvernail/Getty Images)In the handle of the pan-shaped Big Dipper (part of Ursa Major) is the pair of stars called Mizar and Alcor. They make a lovely visual double, easily seen with the naked eye, and they really pop when viewed through 10x50 binoculars, with Mizar the brightest at magnitude 2 and Alcor a little fainter at magnitude 4.
Some double stars are just visual doubles, meaning they are many light-years apart and unrelated, but they just happen to be very close to each other on the night sky as seen from our line of sight. Not so with Mizar and Alcor, which are physically bound by gravity as they orbit each other. However, view Mizar and Alcor through binoculars, and you will get a glimpse of the true magnificence of this system. Large binoculars will show that Mizar is also a double star. Resolving Mizar as two stars is probably pushing it in 10x50s, but a pair of 20x80 binoculars will give you a better chance of splitting them, with image-stabilized binoculars, if you have them, giving you the edge.
There’s even more in the Mizar and Alcor system than what binoculars can show. Both stars in the Mizar system are also doubles, as is Alcor, making this a six-star system in total! Sadly, these extra companions are so close together that not even telescopes can split them. But there are plenty of other doubles for you to hunt down with binoculars. The trick is to find double stars that have a wide enough separation to be resolvable by 10x50 binoculars. Try also Epsilon Lyrae and Alpha Librae, also called Zubenelgenubi, meaning ‘southern claw’, as it was once associated with the constellation Scorpius the Scorpion, before being moved into Libra the Scales.
Auriga’s open clustersThe tadpole nebula, IC 410, in the constellation Auriga. Averted vision, powerful magnification and a tripod are a must to see this with binoculars. (Image credit: Getty Images)Auriga the Charioteer is a constellation famed for two things: its brilliant yellow star Capella (the sixth brightest in the entire night sky), and its array of magnificent open clusters, notably Messier 36, 37 and 38.
Open clusters are young clusters of stars that were born together and are now gradually dispersing, and Auriga’s open clusters are some of the best and brightest of their kind in the night sky.
A pair of 10x50 binoculars can have a field of view between 5 and 7 degrees, depending upon the model. For the larger field, it’s possible to squeeze all three of Auriga’s open clusters into the same view!
To find the clusters, first drop down from Capella to alight on the bright star Elnath, which is actually Beta Taurii in the constellation of Taurus the Bull. You can find Elnath easily with the unaided eye. Switching to binoculars, look about three-quarters of the way along the line between Capella and Elnath. You should see six fainter stars of magnitude 6 forming a curve. Follow that curve west, and you’ll come across two other magnitude 6 stars close to M38, which appear as a hazy patch whose diffuse light is made from a multitude of faint stars. This is the case for all three clusters. Most of M38’s stars are not resolvable in binoculars, but some certainly are in 10x50s, and switching to larger aperture binoculars or an image-stabilized model will help to reveal more.
Just 2.5 degrees to the south-east is the next cluster, M36, which overall is brighter than M38. Through 10x50s look for eight or ten stars; again, large binoculars will reveal more.
Finally, M37 is located a little further away. The constellation of Auriga has an obvious five-sided shape marked by its main stars and Elnath. Draw an imaginary line between Elnath and Auriga’s bright star at its lower left, magnitude 2.6 Theta Aurigae. Messier 37 is found about halfway along and just outside of this line. Another hazy patch, it is the densest of the three clusters, but most of its individual stars are fainter than in M36 and M38, so M37 will need larger binoculars, say 25x100, to get the best out of it.
After spending time looking at the three clusters, sweep your binoculars along the splendor of the winter Milky Way, in which Auriga sits. Through binoculars, the vast star fields of the Milky Way are spellbinding.
The Andromeda Galaxy M31This is a typical view of the Andromeda galaxy (M31) that you can easily achieve with binoculars, but dark skies and averted vision aid detail. (Image credit: Omid Qadrdan)The Andromeda Galaxy (Messier 31) is the closest large spiral galaxy to our Milky Way galaxy, located 2.5 million light-years away. That means it is large and relatively bright in our night sky, making it a great target for binocular users. If you are observing from a dark site away from city lights, you will probably be able to see it with the naked eye.
If you can’t or are having trouble knowing where to look:
- Use the stars of the nearby constellation Cassiopeia to find it. Cassiopeia has the shape of the letter ‘W’. Use the bottom star on the right of the W — the brightest star in Cassiopeia, Alpha Cassiopeiae or Schedar — to...
- Point down towards Andromeda and its bright star Beta Andromedae, or Mirach.
- Now using 10x50 binoculars, move north-west until Mirach is at the bottom-left of your field of view and the star Mu Andromedae is at the top-right.
- Then move your binoculars the same distance in the same direction again, and you should find the Andromeda Galaxy.
While you won’t be able to resolve its spiral arms, you will see a smudge of light that is its disk, and a brighter core. Also look out for its two companion galaxies, M32 beneath it and M110 to the top-right. Both appear as fuzzy stars and, depending on how dark your observing site is, you may need to use averted vision to see them (looking at them out of the corner of your eye). Larger binoculars, say 25x100, will show M31 and its companions much more easily, though you’ll need a tripod to take their weight.
Perseverance rover watches alien solar eclipse on Mars | Space photo of the day for Aug. 19, 2026
People around the world enjoyed stellar views with last week's total solar eclipse.
And the day after we looked up to see the moon obscuring out sun, NASA's Perseverance Mars rover looked up to see its own Martian solar eclipse.
What is it?Solar eclipses aren't unique to Earth. In theory, any planet with at least one orbiting moon would have times where that moon might eclipse some part of its sun to anyone looking up from the planet's surface.
On Aug. 13, 2026, one day after Earth's total solar eclipse in which our moon temporarily blocked out our sun for skywatchers in some locations, Mars saw its own solar eclipse.
Looking up with its left Mastcam-Z camera, Perseverance snapped this image of one of Mars' two moons, Phobos and Deimos, partially eclipsing the sun. This appears to be Phobos — the larger of the pair — eclipsing the sun.
Why is it incredible?So far, we humans have only directly had vantage points on Earth, in Earth orbit and on the moon. We have not yet landed humans on Mars, and it remains unclear how long it might be before that happens.
But robotic explorers like Perseverance allow us to travel where we can't go ourselves. Such travelers have taken us into interstellar space and all throughout our solar system. From Saturn's rings to Neptune's distant, icy neighborhood, robotic probes have allowed humanity's reach to stretch far through the cosmos.
And thanks to Perseverance and its two "eyes," the two Mastcam-Z cameras located high on its mast, we can travel right to the surface of Mars, look up and see an alien solar eclipse. What an amazing thing that is.
On this day in space! Aug. 19, 1997: 1st Filipino satellite launches into orbit
On Aug. 19, 1997, the Philippines' first satellite launched into space. Before then, the country's only communications satellite was one that had been purchased from Indonesia after it was already in orbit.
But 29 years ago today, the Mabuhay Philippines Satellite Corporation sent its own satellite into orbit using a Chinese Long March 3B rocket. The new satellite was named Agila-2 in honor of the great Philippine eagle. To this day, it provides the most powerful satellite coverage in Asia and the Pacific, though its ownership has change: In 2009, the Philippines sold it to the Asia Broadcast Satellite company.

For example, astronauts from around the world work together to stay safe and push scientific progress forward on board the International Space Station (ISS). And more and more nations are getting involved in the final frontier these days. Over 70 different nations have signed the Artemis Accords, a U.S.-backed set of guiding principles for responsible space exploration.
The Agila-2 launch was a major breakthrough for Filipino progress in the space sector. It was followed up almost two decades later with the Diwata-1 microsatellite, which launched to the ISS on April 27, 2016. And the momentum kept growing from there, as the Philippine Space Agency was formalized in 2019. Since then, the Philippines has collaborated with NASA and JAXA (the Japan Aerospace Exploration Agency) to develop and launch two more satellites, Diwata-2 and Maya-1.

I sailed to Greenland for a total solar eclipse — what I saw left me speechless
I woke up on the morning of Aug. 12 and looked out of the window to something I hadn't dared hope for: blue sky.
After days of scrutinizing weather models that seemed determined to test the nerves of everyone aboard the HX Expeditions ship MS Spitsbergen, somehow, against the odds, the clouds had cleared. Even then, I didn't trust it (especially after my 2024 eclipse experience). We had traveled thousands of miles, crossed the Greenland Sea and ventured deep into Scoresby Sund to put ourselves in the path of the moon's shadow. Now there was nothing to do but wait — and hope the sky stayed clear.
The wind howled across the deck, but nobody seemed to mind. If anything, it was helping us, keeping the clouds at bay. The atmosphere aboard felt like Christmas Eve with a ship full of overexcited children. Some guests had chased eclipses across the world; for others, this would be their first. Either way, Aug. 12 was the date we'd been waiting years for.
But by the time we reached Scoresby Sund, something had shifted.
I had traveled all this way to look up. Instead, I found myself looking around. I'd come here for 2 minutes and 14 seconds of darkness. Instead, Greenland had spent the previous days relentlessly demanding my full attention.
This trip was made possible by travel and accommodation provided by HX Expeditions.
After a couple of days at sea during the crossing from Svalbard to East Greenland, our first sight of land appeared almost like a mirage on the horizon. Soon, icebergs were drifting past the ship and the scale of the landscape became increasingly difficult to comprehend. We could sail for hours through Northeast Greenland National Park without seeing a single sign of human civilization beyond our own ship. At times, moving through those immense geological landscapes felt less like traveling across Earth and more like exploring some distant, icy-covered moon.
The East Coast of Greenland is one of the most remarkable environments I have ever experienced. (Image credit: Daisy Dobrijevic/Future)Yet, the more otherworldly Greenland appeared, the more it made me appreciate our own planet.
At times it felt as though I'd stepped into a geology textbook. Processes and structures I'd previously seen reduced to diagrams were suddenly towering above me. And amongst all the enormity were the tiniest signs of life: lichens and miniature Arctic plants hugging the ground beneath vast mountains and glaciers.
The scale and contrast were overwhelming at times, and no view stayed the same for long.
An iceberg viewed from one side could morph into a completely different form as the ship sailed past it. A break in the clouds could transform a gray mountainside in seconds. In Scoresby Sund, even the ice seemed to echo the landscape around it as jagged peaks, flat-topped slabs and sculpted ridges rose from the water like miniature versions of the colossal mountains behind them.
A landscape dominated by giants. (Image credit: Daisy Dobrijevic/Future)The Greenland scenery was a gift that kept on giving, and I found myself increasingly reluctant to go inside. I began meticulously scanning for wildlife, because I'd learned how quickly something extraordinary could appear.
On an impromptu evening walk in Longyearbyen before we set sail, beluga whales had suddenly surfaced in the bay. Later, in Greenland, while I was distracted by a spectacular circumzenithal arc and sundogs overhead, one of a handful of people still standing on deck spotted two tiny white shapes in the water. I thought they were birds bobbing along.
Then I lifted my camera and zoomed in.
Polar bears.
Two unexpected visitors. (Image credit: Daisy Dobrijevic/Future, captured with Sony A7RV and FE 400-800mm F6.3-8 G OSS lens)It became something of a lesson for the expedition: stay curious, keep your eyes open and remember to look both up and down.
That curiosity seemed to unite everyone aboard. Guests had traveled from around the world for this eclipse opportunity. There were seasoned eclipse chasers looking to experience totality somewhere extraordinary, first-timers who had no idea how they would react and people drawn as much by the adventure and wildlife, as the eclipse itself.
HX Expeditions' onboard science and education programme gave that shared enthusiasm somewhere to go. Our days were filled with nature landings, lectures, citizen-science projects and conversations with experts, helping us do more than simply travel through Greenland. The programme encouraged us to pay closer attention — not merely to see the landscape, but to understand and truly experience it.
Conversations jumped from eclipses to wildlife, travel, geology and perhaps, inevitably for a ship full of skywatchers, clouds. We took part in the GLOBE Observer cloud citizen science project and found ourselves happily studying them — while collectively hoping they would be nowhere near the sun on eclipse day.
The eclipse had brought us together, but the journey had quickly become about much more.
MS Spitsbergen poised and ready for the total solar eclipse on Aug. 12, 2026. (Image credit: Daisy Dobrijevic/Future)Then, on Aug. 12, our attention returned to the sky.
When the moon took its first tiny bite from the solar disk, excitement rippled across the deck. For the next hour, it steadily consumed more of the sun.
As totality approached, the quality of the light began to change.
It became strangely yellow and dull, yet at the same time the landscape seemed almost unnaturally sharp. It was eerie — familiar enough to still resemble daylight, but wrong enough that your brain knew something extraordinary was happening.
Poised and ready for the eclipse. I captured the image of totality with a Sony A7RV and FE 400-800mm F6.3-8 G OSS lens and a makeshift solar filter using Baader AstroSolar Safety Film. (Image credit: Daisy Dobrijevic/Future)What amazed me most was how long that daylight persisted.
Even when only the tiniest sliver of sun remained, Greenland was still illuminated. I knew scientifically how intensely bright the solar photosphere is, but knowing it and watching that minuscule fraction of sunlight continue to illuminate an entire landscape were two very different things.
Then the final fraction disappeared.
The world around me plunged into twilight.
And there it was.
Totality.
The total solar eclipse viewed from the deck of HX Expeditions' MS Spitsbergen. (Image credit: Daisy Dobrijevic/Future)I knew exactly what I was supposed to see. I've written about eclipses for years. I understand the science. I had seen thousands of photographs of the corona, prominences, Baily's beads and diamond rings.
None of it prepared me for the feeling of actually seeing one.
The first thing that struck me was how large the eclipsed sun appeared to the naked eye. Photographs had never prepared me for that sense of scale, nor how much detail I could see with my own eyes.
The giant pink prominence on the lower left limb was bright enough to see with the naked eye. (Image credit: Daisy Dobrijevic/Future, captured with Sony A7RV and FE 400-800mm F6.3-8 G OSS lens)The moon itself looked impossibly dark — a black void punched into the sky — surrounded by the pearly white corona. Long streamers stretched away from the sun and around the moon's edge I could see bright pink prominences.
I was so surprised to see this vivid pink color with my own eyes. For 2 minutes and 14 seconds, I saw the sun as I had never seen it before.
But even then, I couldn't just look up.
I looked around. Jupiter and Mercury shone clearly off to one side of the eclipsed sun, with Mercury far brighter and easier to spot than I had expected. Venus blazed on the other side.
Then I looked down. Below the eclipsed sun were icebergs. Beside us rose the immense walls of Scoresby Sund. Glaciers carved their path through the landscape.
Above it all hung that black disk and its enormous, delicate corona. My brain simply couldn't take it all in.
There was too much beauty. Too much scale. Too much happening at once.
People use words such as "mind-blowing" and "speechless" so often that they begin to lose their meaning.
But my mind was really blown. And I really was speechless. Perhaps the best way I can describe it is that my mind felt full, but quiet. Full because there was almost too much to comprehend, but quiet because for those fleeting moments, there was room for nothing else.
I was astonished by how much of the corona you could see with the naked eye. (Image credit: Daisy Dobrijevic/Future, captured with Sony A7RV and FE 400-800mm F6.3-8 G OSS lens)The intensity of the experience surprised guests who had originally joined the voyage for different reasons.
"My husband and I came to see the wildlife, and we were actually in awe of what we saw in relation to the solar eclipse," Kenya Haupt, from Colorado, told Space.com. "Truly an emotional experience"
The reasons for joining the expedition varied, but beneath the moon’s shadow, the experience became a collective one.
For Shubhada Maitra, from India, it was her first total solar eclipse.
"When I looked around me, I just had a feeling that we were one community, taking part in one of the most spectacular, perhaps once-in-a-lifetime celestial events," Maitra said. "Although we came from different countries, different nationalities, genders, all of that, that solar eclipse just bound us together."
"Without saying anything, we were just so connected in that experience."
Lisa Marie Morse, from Rhode Island, described the eclipse as both "joyous and melancholy."
"In that moment of darkness, I felt a powerful connection with all living things, to an infinite ancient rhythm locking us together for 134 seconds of shared awareness, then releasing us back into our daily slumber," Morse said. "It was magical."
Then, almost as quickly as totality had arrived, it was ending.
The first brilliant beads of sunlight appeared from behind the moon.
They were beautiful, but there was a sadness in seeing them too. The corona, prominences and extraordinary black void that had dominated the sky were about to disappear once more into the overwhelming glare of the sun.
Two minutes and 14 seconds had somehow felt both packed with experience and impossibly brief. I had just enough time to look with my naked eye, search for planets, check it out through binoculars and try to absorb the reactions around me.
Then it was gone.
For seasoned eclipse chaser Roy Tillcock from the Isle of Wight, the clear view had come as a genuine surprise.
"This was one of the most unexpected eclipses I've seen," he said. "I did not have high hopes of seeing it, and there it was. Brilliant."
And, as if to underline just how fortunate we had been, the clouds rolled in shortly after totality. A few minutes later, and this could have been a very different story.
Some skywatchers were emotional. Others were exhilarated. Many, like me, seemed to be struggling to find words big enough for what had happened.
Perhaps that is part of why eclipse chasing becomes so addictive. We can explain the science of totality in extraordinary detail. We can calculate the path of the moon's shadow years in advance, travel thousands of miles to stand beneath it and know exactly when and where darkness will fall.
But knowing what to expect is not the same as experiencing it.
The following morning, Greenland was still there, still demanding my undivided attention. Icebergs drifted past the ship. Mountains towered above the fjord. The sunlight shifted and the landscape transformed once again. I had traveled all this way to look up.
There was never a bad view as we journeyed through Scoresby Sund aboard MS Spitsbergen. (Image credit: Daisy Dobrijevic/Future)But somewhere along the journey, I had learned to truly look around. Here I was, standing on a planet of glaciers, oceans, wildlife and ancient rock, watching its moon pass perfectly across its star at a moment in Earth's history when their apparent size in our sky happened to match. How lucky are we to experience any of this? Luck, ultimately, is something no eclipse chaser can ignore.
We could calculate where the shadow would fall. We could sail into its path. We could scrutinize forecasts, prepare our equipment and position ourselves as carefully as possible.
But we couldn't command the clouds to cooperate.
Nature always has the final say. And on Aug. 12, 2026, in a remote fjord in East Greenland, nature said yes.
Greenland was full of surprises. (Image credit: Daisy Dobrijevic/Future, captured with Sony A7RV and FE 400-800mm F6.3-8 G OSS lens)Editor's note: This trip was made possible by travel and accommodation provided by HX Expeditions.

Astronomers discover a giant, rocky 'mega-Earth' 23 times more massive than our planet
Astronomers have discovered an unusually massive, dense exoplanet that challenges conventional ideas about how rocky planets form.
Called GJ 523b, the exoplanet is about 2.5 times wider than Earth but packs roughly 23 times our planet's mass into that relatively compact size. Worlds this large and dense are sometimes referred to as "mega-Earths," an informal term for unusually massive, predominantly rocky planets. GJ 523b's high density suggests it contains relatively little atmosphere despite being large enough that astronomers would normally expect it to have accumulated a substantial gaseous envelope, according to a statement from the University of Wisconsin–Madison.
"This isn't what we expected at all," Max Kroft, lead author of the study, said in the statement. "Dense planets like this aren't uncommon, but they're usually small rocky planets similar to Earth or Mercury. This planet is two and a half times bigger than the Earth."
GJ 523b was initially identified as a candidate by NASA's Transiting Exoplanet Survey Satellite (TESS), which searches for periodic dips in starlight caused when planets cross, or transit, their host stars. Researchers followed up with observations from the ground-based WIYN 3.5-meter Telescope at Kitt Peak National Observatory in Arizona, using a spectrograph to measure the planet's gravitational tug on its star.
Combining those observations, the team calculated that GJ 523b has a mass about 23.5 times that of Earth, a radius 2.55 times larger and a density of about 126.82 grams per cubic inch. It circles its star every 17.75 days. The planetary system is also relatively young, at an estimated nearly 170 million years old, according to the study.
That combination of size, mass and youth poses a puzzle for planet formation models. Planets begin by building cores of rock and metal, which can then pull in hydrogen and helium from the disk of gas and dust surrounding a young star. In our own solar system, giant planets such as Jupiter and Saturn are thought to have begun rapidly accumulating their massive gaseous envelopes once their growing cores reached roughly 20 times Earth's mass.
GJ 523b is already about 23 times Earth's mass, putting it beyond that threshold. Yet instead of developing into a gas-rich world, its unusually high density suggests it has relatively little gas and remains predominantly rocky — raising the question of why it followed such a different path.
"The question is, why didn't this planet do that, if it's 20 times the size of Earth?" Kroft said in the statement.
One possibility is that GJ 523b initially formed with a thick atmosphere that was later stripped away. Another is that it formed through a collision between two planets, creating a larger rocky world while blasting much of their gaseous envelopes into space, according to the statement.
Astronomers have used the term "mega-Earth" for more than a decade to describe exceptionally massive rocky worlds, though it has never represented a formally established class of exoplanets. Finding more examples like GJ 523b could help reveal whether these unusual worlds are rare exceptions or part of a broader population.
"It's hard to infer things about planet formation in general from a sample size of one," Kroft said in the statement. "We're not going to get to 10,000 of these overdense planets, but if we can get to 20 or 30, maybe some trends might pop out."
The findings have been submitted to The Astronomical Journal and are currently available on the preprint server arXiv and have not yet been peer reviewed.
Fly around Schiaparelli Crater with Mars Express
ESA’s Mars Express takes us on another mesmerising flight, this time around one of the biggest craters on Mars.
Despite measuring a huge 460 km across, Schiaparelli Crater seems to be relatively shallow. Perhaps it has been filled in over the last few billion years by sediment blown by the wind or deposited by water, by lava – or by a combination of all three.
Schiaparelli Crater is named after Italian astronomer Giovanni Schiaparelli (1835–1910). Although he studied Mercury and Venus, he is best known for his observations of the Red Planet.
During the ‘Great Opposition’ of 1877, when Mars passed close to Earth, Schiaparelli mapped the planet, perceiving several straight dark lines across the red surface. He assumed that these were natural water-filled channels and used the equivalent Italian word, ‘canali’.
However, other astronomers thought he meant canals, meaning artificial irrigation and transportation routes, which led to a few astronomers, and a large number of the general public, believing that they had been created by intelligent martians.
Now we know that Schiaparelli’s ‘canali’ were illusions created by the comparatively poor telescopes of the time and there are no water-filled channels on Mars today. Nevertheless, we do believe that water was once present in this region of the planet, perhaps in the form of a lake.
Schiaparelli Crater is also important in popular culture, being the final destination of astronaut Mark Watney in Andy Weir’s novel ‘The Martian’.

Processing notes:
This film was created using the Mars Express High Resolution Stereo Camera Mars Chart (HMC-30) data, image mosaics made from multiple observations by the mission’s High Resolution Stereo Camera (HRSC). The mosaic image, centred at 8°S/17°E, is combined with topography information from the digital terrain model to generate a three-dimensional landscape.
For every second of the movie, 50 separate frames are rendered following a predefined camera path in the scene. The vertical exaggeration used for the animation is three-fold. Atmospheric effects, like clouds and haze, have been added to conceal the limits of the terrain model. The haze starts building up at a distance of 250 km.
The HRSC camera on Mars Express is operated by the German Aerospace Center (DLR). The systematic processing of the camera data took place at the DLR Institute for Space Research in Berlin-Adlershof. The working group of Planetary Science and Remote Sensing at Freie Universität Berlin used the data to create the film.
Behind the Lens: Meet NASA Johnson’s Photographers
Photographers at NASA’s Johnson Space Center in Houston have documented some of the most defining moments in human spaceflight.
From astronaut training and engineering tests to mission control operations and milestone celebrations, their images preserve the history of exploration while capturing the people and teams behind the missions shaping the next era.
Meet the photographers behind the lens and explore the stories behind the images that have helped tell NASA’s story.

NASA Photographer
For more than three decades, NASA photographer Robert Markowitz has documented the people and milestones that have shaped NASA’s human spaceflight program. His career has spanned the space shuttle program, 25 years of continuous human presence aboard the International Space Station, and Artemis II.
“My favorite part of this job has always come down to the range of assignments we take on and the people I get to work with every day,” Markowitz said.
One of Markowitz’s early career highlights came during the filming of “Apollo 13,” when he served as the behind-the-scenes still photographer for nearly every KC-135 zero-gravity flight. “Looking back as a 25-year-old photographer at Johnson, I don’t think I fully appreciated how unique an opportunity it was to be there documenting those moments,” he said.
Markowitz says the job has challenged him to grow as both a photographer and a communicator. Whether photographing dozens of individual portraits in a day or coordinating a 300-person group photo, each assignment has strengthened his ability to adapt, collaborate, and connect with people.
“This work has shaped not just my career, but my life,” he said. “Being part of a team that captures and preserves the story of human spaceflight continues to be one of the great honors of my time at Johnson.”

NASA Photographer
NASA photographer Bill Stafford’s path to Johnson began during his senior year of college, when a friend who was completing a photography internship at the center told him about an opening on the photography team. With a longtime interest in science and technology, Stafford saw the opportunity to combine those interests with photography in an extraordinary environment.
Stafford approaches each assignment as a technical challenge and a storytelling opportunity. Whether working around constraints in lighting, timing, or access, he uses composition, visual psychology, and an understanding of how a viewer’s eye moves through an image to shape the final photograph.
“My favorite part of the job is the problem-solving that comes with it,” Stafford said.
Working at Johnson has sharpened those instincts as he photographs spacecraft, hardware, astronauts, and the people behind NASA’s human spaceflight missions.
“So many of the subjects I photograph carry weight and history that I want the image to reflect,” he said.

From newspapers across the country to working as a photographer and photo editor for a publication in Ecuador, NASA photographer James Blair began his career in photojournalism. Photography has taken him around the world, a path that has continued at Johnson with assignments ranging from astronaut training to geology field training in Iceland.
“Since I was very young, I have always been fascinated by spaceflight and the technology it takes to reach beyond Earth’s atmosphere,” Blair said.
At Johnson, Blair combines that fascination with his photojournalism background to document the people and technology shaping NASA’s next era of exploration.
“I enjoy documenting the new hardware that is being developed to return us to the Moon,” he said. “From spacesuits to rovers and potential lunar habitats, I get to show the world what NASA has in store for the future of human spaceflight.”

NASA Photographer
NASA photographer Helen Arase Vargas began her career in photojournalism and reporting in Southern California before joining Boeing’s scientific photography team in El Segundo. Her experience photographing aerospace sparked an unexpected interest that eventually led her to Johnson.
“The best part of the job is my coworkers; cheesy, but there is so much to learn from everyone,” Arase Vargas said. “Our core team has so much knowledge. They are all quick to offer help and are great humans.”
Arase Vargas says much of the work at Johnson reflects the journalism ethics she learned early in her career and fulfills her desire to serve the public interest.
The range and volume of assignments also helped her become more comfortable working in different environments while continuing to develop her craft.
For Arase Vargas, documenting the Artemis II crew’s return to Ellington Field in Houston came with a heightened sense of responsibility.
“The world is watching, and all that imagery must be rushed out by the lab,” she said. “Your photo could be the one that ends up on every news site, and you don’t want to miss capturing the joy and celebration the moment deserves.”

NASA photographer Luna Posadas Nava’s path to Johnson spans emerging technology, optics and imaging systems, and photographing artists across the East Coast. Her work grew from a desire to visualize and expand the boundaries of what is possible.
Joining Johnson shortly before the launch of NASA’s Artemis II mission, one of Posadas Nava’s first experiences was helping bring Moon Joy to the world. She documented the Science Evaluation Room, where scientists worked together to conduct real-time lunar science observations during the mission’s lunar flyby.
Posadas Nava said it was inspiring to witness the team at work and especially meaningful to see so many women contributing to the mission’s science.
Seeing the response from women in her own life and online reinforced for Posadas Nava the power of representation through photography.
“When we see ourselves in stories, we imagine new futures,” she said. “I hope my work helps more people see themselves in the story of exploration, because what we see shapes what we believe is possible.”

NASA Photographer
Growing up in Houston during the Apollo era, NASA photographer David DeHoyos knew from an early age that he wanted to be part of the space industry. His interest in photography began with his mother’s Kodak Instamatic camera and continued through school and a decade working in photo labs. In 1991, that path brought him to Johnson’s photo lab and eventually behind the camera as a NASA photographer.
After more than three decades at Johnson, DeHoyos says connecting with people remains one of his favorite parts of the job. He enjoys learning about the people he photographs, sharing what he has learned about Johnson with visitors and new employees, and encouraging the next generation.
“I keep an assortment of NASA goodies in my camera bag, and the ultimate joy I get is giving a pin or sticker to a child and seeing their little faces just light up,” DeHoyos said. “It just warms my heart to encourage a youngster to work hard and pursue their dreams because that’s how I got here.”
For DeHoyos, photography is also about preserving moments that can take on greater meaning over time.
“I love the process of figuring out technical details to create an image that will make someone say, ‘Wow, cool shot, how did you do that?’” he said.

Arase Vargas says much of the work at Johnson reflects the journalism ethics she learned early in her career and fulfills her desire to serve the public interest.
The range and volume of assignments also helped her become more comfortable working in different environments while continuing to develop her craft.
For Arase Vargas, documenting the Artemis II crew’s return to Ellington Field in Houston came with a heightened sense of responsibility.
“The world is watching, and all that imagery must be rushed out by the lab,” she said. “Your photo could be the one that ends up on every news site, and you don’t want to miss capturing the joy and celebration the moment deserves.”

NASA photographer Luna Posadas Nava’s path to Johnson spans emerging technology, optics and imaging systems, and photographing artists across the East Coast. Her work grew from a desire to visualize and expand the boundaries of what is possible.
Joining Johnson shortly before the launch of NASA’s Artemis II mission, one of Posadas Nava’s first experiences was helping bring Moon Joy to the world. She documented the Science Evaluation Room, where scientists worked together to conduct real-time lunar science observations during the mission’s lunar flyby.
Posadas Nava said it was inspiring to witness the team at work and especially meaningful to see so many women contributing to the mission’s science.
Seeing the response from women in her own life and online reinforced for Posadas Nava the power of representation through photography.
“When we see ourselves in stories, we imagine new futures,” she said. “I hope my work helps more people see themselves in the story of exploration, because what we see shapes what we believe is possible.”

Growing up in Houston during the Apollo era, NASA photographer David DeHoyos knew from an early age that he wanted to be part of the space industry. His interest in photography began with his mother’s Kodak Instamatic camera and continued through school and a decade working in photo labs. In 1991, that path brought him to Johnson’s photo lab and eventually behind the camera as a NASA photographer.
After more than three decades at Johnson, DeHoyos says connecting with people remains one of his favorite parts of the job. He enjoys learning about the people he photographs, sharing what he has learned about Johnson with visitors and new employees, and encouraging the next generation.
“I keep an assortment of NASA goodies in my camera bag, and the ultimate joy I get is giving a pin or sticker to a child and seeing their little faces just light up,” DeHoyos said. “It just warms my heart to encourage a youngster to work hard and pursue their dreams because that’s how I got here.”
For DeHoyos, photography is also about preserving moments that can take on greater meaning over time.
“I love the process of figuring out technical details to create an image that will make someone say, ‘Wow, cool shot, how did you do that?’” he said.
