At Cosmic Noon, this Black Hole Was the Life of the Party
About 3 billion years after the Big Bang, star formation exploded across the cosmos. During the era dubbed "cosmic noon.” It was also when galaxies and supermassive black holes were growing faster than at any other time in the history of the universe. Now astronomers have discovered a monster from this frenzied period: a supermassive black hole unleashing jets that stretch over 300,000 light-years into space, revealing the sheer violence of its feeding frenzy.
Filtering Terrestrial Contamination in the Search for Alien Signals
How can radio astronomers successfully identify extraterrestrial radio signals while discerning them from Earth-based radio signals? This is what a recent study published in The Astronomical Journal hopes to address as a team of researchers investigated how machine learning could be used to search for extraterrestrial technosignatures while simultaneously identifying radio contamination from human radio signals. This study has the potential to help radio astronomers develop more efficient methods in searching for and identifying radio signals from extraterrestrial civilizations.
Webb Directly Observes a Frigid Exoplanet
Most exoplanets have been detected indirectly through the transit or radial velocity method. But here's an image of the exoplanet 14 Herculis c captured by Webb. It has been described as a "chaotic" and "abnormal" planetary system and is about 7 Jupiter masses, but with a surface temperature of only -3°C. The discovery offers new insights into how planetary systems can develop in dramatically different ways from our own Solar System.
Colliding Galaxies Tearing at Each Other with Gravity and Radiation
Astronomers recently used a pair of powerful telescopes to zero in on a cosmic battle going on some 11 billion light-years away from us. The combatants are a pair of galaxies charging at each other over and over again, at velocities upwards of 500 kilometers per second. According to one of the scientists studying the scene, one galaxy is cutting into the heart of the other with a blast of radiation.
Martian Supervolcano Peeks Through the Cloudtops
NASA's 2001 Mars Odyssey orbiter captured this incredible image of the giant shield volcano Arsia Mons, poking through the cloud tops at Martian dawn. Arsia and the other megavolcanoes on Mars are so tall they're often surrounded by water ice clouds in the early morning. Odyssey is normally staring straight down, so to capture this unique angle, it had to rotate 90 degrees while in orbit so that it could capture a side perspective view of the volcano.
Surviving the Neptunian Desert
As astronomers found more and more exoplanets in recent years, they've discovered an unusual gap in the population. It's called the Neptunian Desert, a curious scarcity of Neptune-sized exoplanets orbiting close to their stars. Researchers just discovered an exoplanet in the Neptunian Desert around a Sun-like star. Can it help explain the Desert?

Now I know this sounds like a low-budget knockoff of Five Nights at Freddy's, but it's the real deal
The Martian Atmosphere is Sputtering
The Earth's atmosphere is protected by a magnetosphere, but Mars lacks this protective shield and lost its atmosphere to space long ago through interactions with the solar wind. In a new paper, scientists report that they have directly observed this process of "atmospheric sputtering," watching how incoming ions from the solar wind directly cause neutral atmospheric particles to escape. They found the process is stronger than anticipated, especially in solar storms.
The Sun's Identity Crisis Solved
The Sun's surface has unveiled a new secret: ultra fine magnetic "curtains" that create striking patterns of bright and dark stripes across the solar photosphere. Thanks to groundbreaking observations from the NSF Daniel K. Inouye Solar Telescope in Hawaii, scientists have captured the sharpest ever images of these previously unseen structures, revealing magnetic field variations at scales as small as 20 kilometres.
The Nuclear Option: Europe's Plan for Faster Space Travel.
Whilst NASA funding has been slashed by the Trump administration with no allocation for Nuclear Thermal Propulsion or and Nuclear Electric Propulsion, scientists at the European Space Agency (ESA) have been studying nuclear propulsion.
This Map of the Cosmic Web Reaches Back in Time
The COSMOS scientific collaboration has released the largest map of the Universe ever created. It contains almost 800,000 galaxies, some from the Universe's earliest times. The map challenges some of our ideas about the early Universe.
NASA's Top 5 Technical Challenges Countdown: #2: More Power
What we have now just…isn't going to cut it. Right now if you want power in space you essentially have two options: solar panels, and a kind of nuclear power called radioisotope thermoelectric generators.
NASA's Top 5 Technical Challenges Countdown: #3: Better Computers
Computers have been involved in spaceflight since almost the very beginning. Just like on the Earth, computers aid in a variety of tasks, like navigation and communication. But unfortunately, space is really, really unkind to electronics.
NASA's Top 5 Technical Challenges Countdown: #4: Improved Navigation
But in space, like on the Moon or Mars, we have…none of that. Zero. No GPS satellites, no globe-spanning networks. Just radio broadcasts from command centers here on Earth to tell our robots and crews what to do.
NASA's Top 5 Technical Challenges Countdown: #5: High-Powered Robotics
Space is hard. There's no doubt about that. It's completely unlike any environment we have ever faced on the Earth.
We Can Use Black Holes Particle Accelerators
The Large Hadron Collider has changed particle physics, and now scientists are dreaming up even bigger supercolliders. But humanity can't match the raw particle-colliding power of a supermassive black hole. In a new paper, researchers describe how supermassive black holes create a dense environment where particles are spinning at relativistic speeds and crashing into each other, releasing other particles that could be detectable on Earth.

Earth planning date: Monday, June 9, 2025
The image above shows the drill poised on the surface of Mars at the start of our attempt to collect sample at “Altadena” over the weekend. Now we know, from subsequent imaging and telemetry, that the drill activity was successful, allowing planning today to focus on delivering sample powder to CheMin and SAM. CheMin and SAM will give us their distinct and valuable insights into the mineralogy (CheMin) and volatiles and organic compounds (SAM) within Altadena, which are key to our continued unravelling the history of Mt. Sharp. It is always exciting to find out what each of these instruments uncovers from Martian samples.
In addition to those sample deliveries, we had three other Altadena-focused activities. We acquired ChemCam RMI of the drill hole which helps ChemCam refine their laser targeting for future LIBS analyses of the drill hole. We planned a ChemCam passive spectroscopy observation of the cuttings around the drill hole for more insight into the mineralogy of the sample. We also included a single Mastcam M100 image of the drill hole which helps us track the wind activity at the drill site and thus the stability of the cuttings ahead of planned observations with APXS and MAHLI.
The weekend activities ran faster and more efficiently than modeled so that we had power to add additional science observations into the plan. We gathered more ChemCam data from the bedrock near Altadena at the target “Bolsa Chica,” and planned two ChemCam RMI long distance mosaics on sedimentary structures within “Texoli” butte and nearby boxwork structures. We kept track of the environment around us with yet more Mastcam imaging for wind-induced changes in the “Camp Williams” area, regular RAD and REMS measurements, two DAN measurements, and Navcam dust devil imaging and cloud movies.
