Simulations explore nuclear mitigation of asteroid threats

Lawrence Livermore National Laboratory (LLNL) researchers are developing three-dimensional simulations to examine how a nuclear device could be used to deflect or potentially disrupt an asteroid threatening Earth.

Salt crystals could hold clues to life beneath Enceladus’s ice

The ocean beneath Saturn’s moon Enceladus lies under kilometers of ice, but some of its contents do reach the surface. Jets near the south pole spray out water vapor and icy particles, offering a way to investigate the hidden ocean without drilling down to it.

Lone, starless cloud may be a ‘dark’ galaxy

Astronomers using China’s FAST radio telescope have discovered a compact cloud of hydrogen with no visible stars or galaxy around it. This could be one of the strongest candidates yet for an isolated “dark galaxy,” containing nearly 500,000 times the sun’s mass in neutral hydrogen. The discovery paper was posted to the arXiv preprint server […]

Astronomer leads global team on NASA mission to create unprecedented view of the early universe

A University of Missouri astronomer is leading a team of 130 researchers from 62 institutions—including NASA, the California Institute of Technology, Princeton University and Harvard University—on an ambitious mission to capture an unprecedented view of the early universe.

New 3D model reveals how shadows reshape chemistry in stellar nurseries

How do young stars reshape the clouds from which they are born? A new high-resolution 3D model developed by an international team led by Dr Brandt Gaches from the University of Duisburg-Essen shows how the uneven structure of stellar nurseries creates shadows that alter their chemistry and influence the infrared emission observed by the James […]

Plants shift gene activity within minutes of entering spaceflight, experiment reveals

Plants begin responding to spaceflight almost immediately after leaving Earth, according to a new University of Florida study that captured the earliest stages of biological adaptation during a commercial suborbital mission. Published in the journal npj Microgravity, the study reports the results of an experiment conducted by a UF astronaut during Blue Origin’s New Shepard […]

First comprehensive Mars soil classification offers framework for exploration and future farming

A Ph.D. student at the University of Sydney has produced the first comprehensive classification system and map of Martian soils, creating a new framework that could help scientists compare landscapes across the Red Planet and identify promising locations for future exploration, habitation and food production.

NASA’s Hubble spies spiral’s edge

This NASA Hubble Space Telescope image features the edge-on, intermediate spiral galaxy NGC 1827, located roughly 37 million light-years away in the constellation Columba, the Dove. Hubble captured the image as part of a survey looking at 260 satellite galaxies around 22 Milky Way–like host galaxies within a radius of about 32 million light-years from […]

A distant supercluster of galaxies points to self-interacting dark matter

Seven billion light-years from Earth, there is an unexpected cluster of galaxies. It has two regions in the process of colliding with each other with a combined mass of more than two quadrillion solar masses. Given its mass, the distant cluster has been nicknamed El Gordo, the Fat One. What makes it unusual is that […]

Elon Musk unveils Tesla’s ‘flying’ car

Forecasting air drag with deep learning helps predict when uncontrolled satellites and rocket stages fall to Earth

On May 10, 2025, a spacecraft built in the Soviet Union to land on Venus came home. Launched in 1972, Cosmos-482 was stranded by a failed upper stage of its rocket and circled Earth for 53 years. In its last days, several space agencies and research groups forecasted when it would fall, and therefore where. […]

Shredded star reveals a massive black hole wandering far from its galaxy’s center

Astronomers have discovered a star being torn apart by a massive black hole more than 1,000 parsecs from the center of its host galaxy. The tidal disruption event, TDE 2023mfm, was first discovered by ZTF and then studied with a wide range of telescopes, including Keck, Lick, Hubble, Swift, Chandra, XMM-Newton and the VLA. The […]

Rigorous analysis confirms NASA’s Artemis II heat shield performance

NASA’s Artemis II mission sent four astronauts around the moon and brought them safely back to Earth, laying a foundation for crewed flights to the moon’s surface.

Lunar fault maps reveal how much the moon is shrinking

A new study of young tectonic landforms on the moon offers the most detailed estimate yet of how much the moon has contracted as its interior gradually cooled over time.

How did Mars get its moons? Japan’s MMX space mission aims to solve the puzzle

The Earth got its moon when a small planet collided with our planet more than 4 billion years ago. This impact hurled molten rock into space, which eventually coalesced to form the satellite we can see every night from across our planet.
