Artificial tissues that mimic the placenta, endometrium, ovary and vagina could point to treatments for common conditions such as preeclampsia and endometriosis

It was the strongest gravitational wave signal yet measured -- what did it show?

How massive can a normal star be?

On Saturn, the rings tell you the season.

Does the Sun set in the same direction every day?

What can auroras on a rogue planet teach astronomers about planetary formation and evolution? This is what a recent study published in Astronomy & Astrophysics hopes to address as an international team of researchers investigated the atmospheric composition of a nearby rogue planet, including its atmospheric temperature and auroras. This study has the potential to help astronomers better understand rogue planets, along with additional planetary atmospheric formation and evolutionary traits.

What new methods can be employed to help astronomers distinguish the light from an exoplanet and its host star so the former’s atmosphere can be better explored? This is what a recent study accepted to Astronomy & Astrophysics hopes to address as an international team of researchers investigated how a novel and proposed telescopic instrument that could be capable of characterizing exoplanet atmospheres in new and exciting ways. This study has the potential to help scientists develop novel tools for examining exoplanets and whether they could possess life as we know it, or even as we don’t know it.

NASA’s James Webb Space Telescope has revealed a colorful array of massive stars and glowing cosmic dust in the Sagittarius B2 molecular cloud, the most massive and active star-forming region in our Milky Way galaxy.

NASA announced that Artemis II, the first crewed mission to the Moon since the Apollo Era, will launch by February 2026. The crew has named their spacecraft "Integrity" to honor the efforts those working tirelessly to realize NASA's long-awaited return to the Moon.

A new article published in The Astrophysical Journal explores a new theory of how Type Ia supernovae, the powerful stellar explosions that astronomers use to measure distances across the universe, might be triggered. Traditionally, these supernovae occur when a white dwarf star explodes after interacting with a companion star. But this explanation has limitations, leaving open questions about how these events line up with the consistent patterns astronomers actually observe.

A study of Saturn's atmospheric structure using data from the James Webb Space Telescope (JWST) has revealed complex and mysterious features unseen before on any planet in our Solar System. The results were presented last week by Professor Tom Stallard of Northumbria University, at the EPSC-DPS2025 Joint Meeting in Helsinki.

Mars holds a special place in my heart being the second planet I saw through a telescope. It’s probably fair to say that it’s held a special place for many as we continue to explore the fascinating world that is the red planet. Scientists studying Mars have recently uncovered a seasonal phenomenon that could change our understanding of the potential for it to support life. Their discovery, a swirling polar vortex that forms of the Martian north pole every winter.

Tumbleweeds offer iconic visual depictions of desolate landscapes. Though typically associated with the American West, the most common type of tumbleweed actually originated in Europe, and is known scientifically as salsola targus, or more commonly as Russian thistle. So its only fitting that a team led by European scientists has some up with an idea based on the tumbleweed’s unique properties that could one day have groups of them exploring Mars.

Visual observations have, over the years had to battle light pollution, weather, aircraft and even satellite constellations. Radio observations have until recently, been reasonably well protected however in their attempt to preserve the “quiet skies” a team of radio astronomers have secured a significant victory. For the first time, they've joined forces with the International Special Committee on Radio Interference, a committee that sets global standards for preventing electronic interference.

Are we alone in the universe? It’s a question that has plagued us since the ancient Greeks posed it for the first time in the 5th century and since then we have tried all manner of ways to reach out to our alien cousins….if they exist. We have fixed golden plaques to space probes, beamed messages out from radio telescopes and in 2012 even sent 10,000 ‘X’ (formerly twitter) messages out to three star systems with the hashtag #ChasingUFOs! A new tool has been developed, rather mundane compared to these other examples, which is no bigger than a soft drink can and could detect signs of life on alien worlds with unprecedented precision.

The JWST examined the most vigorous star-forming region in the entire galaxy. It's called Sagittarius B2, and while astronomers have studied it in detail, no other telescope reveals its details the way the JWST can.

Imagine an engine with no moving parts that runs on continuous explosions. I’m actually sure I one saw a hilarious video of such a device some years ago but alas, am unable to find it and share. Still, the image of the poor occupants being constantly pressed into their seats and accelerated in a series of explosions is likely to be quite a long way from the reality of the new Rotation Detonation Engine. The team of researchers Lehigh University are behind the idea and have just received $2 million to solve the biggest challenge standing in its way, finding materials to build the thing out of that are tough enough to survive the punishment.
