More and more details about 3I/ATLAS are filtering through the scientific process as time goes on. Our third known interstellar visitor attracted the attention of some of the most powerful observatories in the world when it was discovered in July 2025, and some of those telescopes found something peculiar - the isotopes it contained appeared different. A new paper submitted to The Astrophysical Journal Letters (and available in pre-print on arXiv) by Kenji Furuya of the RIKEN Pioneering Research Institute in Japan and his co-authors, shows how that isotopic discrepancy is likely due to the “low-metallicity” of the stellar nursery 3I/ATLAS was born in.

Scientists have known for a while that meteorites contain the “building blocks” of life - complex organic molecules such as amino acids, simple sugars, or even the chemical rungs of DNA. But anyone who has taken an organic chemistry class knows there are plenty of other carbon-based molecules out there, and a new study from Joseph W. Frye-Jones of the National High Magnetic Field Laboratory and Florida State, which was published in The Planetary Science Journal, found tens of thousands of types of previously unseen organic compounds in two of the world’s most famous meteorites.

The discovery of a very early and rare proto-supercluster of infant galaxies may help give clues to the formation of such clusters and their connection to the Cosmic Web.

There are more than 450 confirmed moons orbiting the eight major planets, but only a handful of them provide unique scientific value to pique the interests of the scientific community, specifically their potential for hosting life as we know it. This is due to the subsurface oceans that exist beneath icy crusts, including Jupiter’s Europa and Ganymede, and Saturn’s Enceladus. But what processes are responsible for producing these subsurface oceans, or potentially preventing them from forming in the first place?

It's easy to think of the Moon as the static constant companion in the night sky. Its face hasn’t visibly changed in millennia, and always faces us with the same side. But looks can be deceiving, as our closest companion is constantly bombarded by asteroids and comets that make small craters across the lunar landscape. While they might not be large enough for us to see with our naked eye, professional Moon watchers can pick up on them. And a recent paper published in Science Advances, describes the largest ever found in modern times.

Earth's center of mass isn't stationary. It drifts seasonally and over the course of years. A new study measures this down to the scale of millimeters and finds the seasonal drift is smaller than we thought.

The Sun’s magnetic fields are a twisty, curvy, ever changing mess. In particular, our star’s polar regions host regions called polar coronal holes that host invisible magnetic highways that stretch out into interplanetary space. But there’s a lot we don’t know about how those highways actually work, and in particular how they give the particles that form the fast solar wind an extra “kick” that sends them zooming at hundreds of kilometers per second. A new paper from a team led by Dr. Yuhang Gao and Prof. Hui Tian at Peking University, and published recently in the journal National Science Review, thinks they might have found an answer by using high-speed shots from Solar Orbiter to detect never-before seen rapid, high-frequency magnetic waves in those areas.

X-rays showcase some of the most unique astronomical objects in the universe. Neutron stars and black holes siphoning gas from companion stars stick out like sore thumbs at this level of radiation. However, according to a new paper by Mustafa Muhibullah and Jimmy Irwin from the University of Alabama and Rosanne Di Stefano from the Center for Astrophysics at Harvard & the Smithsonian, there appears to be another group of ultra-bright X-ray emitters that we’ve completely missed until now. They call them Hypersoft X-ray Sources (HSSs) and, according to a press release accompanying the paper, might answer two long-standing astronomical questions.

We have long known that the Sun is active. It “flares” quite often, sending huge amounts of energy off in a certain direction - sometimes directly at Earth. But we also know that, compared to other Sun-like stars, it seems relatively quiet, and not capable of producing the “superflares” we sometimes see in its stellar equivalents. That sounds like great news for humanity, and some scientists have even argued that lack of superflares was a critical impetus for the development of complex life on Earth. But a new paper from Natalie Krivova of the Max Planck Institute for Solar System Research and her co-authors in the journal Philosophical Transactions A calls the assumption that our Sun is incapable of such dramatic outbursts into question. That also means that, eventually, our highly technological society could bear the brunt of one of them.

MIT PhD candidate Lanie McKinney is developing technology to convert the chemicals in the Martian atmosphere into propellant to bring astronauts home.

Scientists theorize that the rapid emergence of supermassive black holes (SMBHs) in the early Universe can be explained by the direct-collapse black hole (DCBH) scenario. In a recent study, astronomers investigated the potential host environments of DCBHs and found that this scenario is a plausible explanation for how the "seeds" of SMBH formed.

BepiColombo's measurements of particle bombardment at Mercury will help assess the impact of space storms on Mercury's surface and on Earth's atmosphere.

Mars appears red because of iron oxides in the regolith. But it's not uniformly red. Different lighting conditions and different materials accumulated on the surface can make it appear purple, as in these images from Mars Express and its High-Resolution Stereo Camera.

Astronomer Sandra Chapman has found a connection between the quiet period of one solar cycle and the active period of the next. Her data shows how a critical cutoff point is the key, but the real test will be the solar maximum of Cycle 26 in the 2030s.

Cosmic topology is as esoteric as cosmology can get. But a growing number of astrophysicists think it holds keys to understanding the universe on its largest scales.

Scientists from Trinity have developed a powerful way to unravel the changing weather patterns on distant worlds. Using this approach, they discovered that the weather on a well-studied brown dwarf, “SIMP 0136”, previously linked with Northern Lights-like phenomena, is largely shaped by just two dominant processes: changes in temperature and the vertical structure of its clouds.

30 years ago, an amateur astronomer noticed a white dwarf star suddenly getting brighter. New research shows this is due to a Very Late Thermal Pulse, a type of helium flash. The star has heated up and become brighter, and is now called a 'born again' star. It's evolved into a Wolf-Rayet type star, and astronomers will get to watch as it continues to evolve on human timescales.

It’s that time of the decade again. Late 2026 going into early 2027 is a special time for the major Jovian moons, as they trade places passing one in front of another as seen from our Earthly point of view. We call this mutual transit-eclipse season, a favorable time to catch the complex interplay of Jupiter’s major moons.

Computer simulations find that overmassive black holes form readily in the early universe. Their spectra match that of Little Red Dots, which later become powerful quasars and supermassive galactic black holes.

If we are ever to have a permanent presence on Mars, we will have to learn to build there. Shipping the material from Earth to build something as simple as a pressurized habitat is prohibitively expensive, so we will have to make sure of the materials available on Mars’ surface. A research team led by Ning Liu at the Hong Kong University of Science and Technology recently published a paper in Chem Circularity that uses biology to do much of the heavy lifting for the structural materials we would typically use concrete for. If their method is adopted, we might quickly find another Earth-based lifeform in abundance on Mars - yeast.
