Einstein told us that massive objects bend light and he was of course, right. Across the universe, giant galaxies are acting as natural telescopes, warping and distorting the light of objects behind them into spectacular arcs and rings. Now the Euclid space telescope wants your help to find them and the scale of the hunt is unlike anything attempted before.

If humans are ever going to live permanently on Mars, someone is going to have to work out where all the raw materials, the food, they oxygen or the material for the structures to name just a few. A new study has tackled that unglamorous but absolutely critical question and the answer involves robots, asteroids, and one of the most complex supply chains ever designed.

NASA's planet hunting telescope has been busy. A new study has just sifted through the light of over 83 million stars and emerged with more than 11,000 potential worlds, including a confirmed giant planet orbiting a distant star. The results don't just add to our catalogue of planets. They fundamentally change where we look for them.

On April 17th, engineers at NASA's Jet Propulsion Laboratory (JPL) sent commands to shut down an instrument aboard Voyager 1 called the Low-energy Charged Particles experiment, or LECP. The nuclear-powered spacecraft is running low on power, and turning off the LECP is considered the best way to keep humanity's first interstellar explorer going.

ASTEP, the Antarctic Search for Transiting ExoPlanets, a small visible telescope operating at Concordia station, continues making a real impact in characterizing odd new exoplanetary systems.

The giant planets in our solar system—Jupiter, Saturn, Uranus, and Neptune—have challenged our understanding of planetary formation and evolution. Specifically, their atmospheric formations and compositions have provided awe-inspiring images from spacecraft and given scientists key insights into the interior mechanisms of these massive worlds. But what about exoplanets? What can their atmospheres teach scientists about their formation, evolution, composition, and interior mechanisms? And how do longstanding exoplanet models stack up against the real thing?

It turns out that even after studying our solar system in depth and discovering more than 6,100 exoplanets across more than 4,500 exoplanetary systems, not all solar systems are created equal. The longstanding notion is that planets orbit almost entirely in the same orbital path, also called an orbital plane. But what if an exoplanetary system was found to have exoplanets that not only orbit in different planes, but also exhibits changing behavior regarding when they pass in front of their star?

The Moon has played a huge role in the development of Earth. It stabilizes the planet, tempered dramatic climate swings, and possibly even provided the tidal heating that might have led to the first life forms. So it’s natural we would want to find a similar Earth/Luna system somewhere else in the cosmos. But astronomers have been searching for one for years at this point to no avail. And a new paper from Emily Pass and her colleagues at MIT, Harvard, and the University of Chicago describes using the James Webb Space Telescope to track some of the most promising exomoon candidates - only to be foiled by the star they were orbiting.

The new Colibre cosmological simulation includes more critical detail than previous simulations. It also includes updated models of things like AGN feedback and star formation. The simulations also include a sonic component, giving the results a cinematic and information-rich flair.

Much of visual astronomy requires nothing more than clear skies, keen eyes, and patience. If you’re out skywatching Saturday evening and live in North or South America, watch for the waxing gibbous Moon pairing with Regulus at dusk. For a privileged region, the Moon will actually blot out or occult the star, in one of the best-placed lunar occultations of a bright star for 2026.

A new analysis of data obtained by JWST on 3I/ATLAS as it was on its way out of the Solar System (in December 2025) showed that its interior is rich in methane ice.

The interplanetary comet 3I/ATLAS is remarkably rich in a specific type of water that contains deuterium, meaning it came from somewhere colder and with lower levels of radiation than our early Solar System.

NASA's MSL Curiosity rover found a bathtub ring-like deposit of zinc, manganese, and iron in Gale Crater. These metals precipitate out of water in the right conditions, and there's not really any other way they could've become concentrated here. Adding to the excitement, these deposits also form in lakes on Earth, where the concentrated metals are food for some types of bacteria.

Neutrinos are very difficult to detect. And when they are detected, pinpointing their sources is likewise difficult. New research shows that the most energetic neutrino ever detected must have had an extraordinarly energetic source. It could even be primordial.

One of the most dramatic and memorable scenes from Interstellar comes from Miller’s planet - and if you don’t want a spoiler for an 11 year old movie, feel free to skip to the next paragraph. When the crew arrives on this potential new home for humanity, they are faced with a literal 1.2 km high wall of water bearing down on them quickly. It’s a great representation of how waves on other planets can act differently than on Earth. Admittedly, according to Kip Thorne, the scientific advisor for that movie, those waves are actually caused by the planet’s proximity to a local black hole rather than the wind that forms our waves here.

One side is scorched to over 200 degrees, while the other is plunged into a darkness so cold it falls below minus 200. Welcome to TRAPPIST-1b and 1c, two rocky worlds that have just revealed the first ever climate maps of Earth sized planets beyond our Solar System. The James Webb Space Telescope has been watching, and what it found tells us something profound about where life might, and might not exist in our Galaxy.

At the heart of our Galaxy lurks a supermassive black hole four million times the mass of our Sun. For decades, astronomers have watched mysterious gas clouds drifting towards it on almost identical paths, wondering where they came from and why. Now, a team of researchers think they have finally cracked the puzzle and the answer involves two massive stars locked in a violent embrace!

An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive stars collapse into black holes—objects with gravity so strong that not even light can escape. But some are completely destroyed in pair-instability supernova explosions. This can explain the so-named "Forbidden Gap" in black hole masses.

MSL Curiosity found 7 new organic molecules preserved in Martian sandstone. While they aren't proof that life existed on Mars, they are important. They show that the planet is capable of protecting ancient biosignatures from radiation and preserving them in rock.

Back in 1997, the Hubble Space Telescope imaged the spectacular Trifid Nebula, a region of active star-formation. Now the telescope has revisited the Trifid. By comparing both images, astronomers have tracked some changes that tell them about how young stars behave and evolve.
