University team proposed retractable, pressurized tunnels for missions to Mars

NASA and China’s national space agency plan to send crewed missions to Mars in the coming decades. Per NASA’s Moon to Mars mission architecture, this will involve using infrastructure established through the Artemis Program to send crews to the red planet sometime in the 2030s or 2040s. Similar to Artemis, these missions will culminate in […]

JWST finds the most distant barred galaxy candidate in the early universe

Astronomers using the James Webb Space Telescope have identified what may be the most distant barred spiral galaxy ever discovered, dating to a time less than 1.2 billion years after the Big Bang. The paper outlining its properties was posted to the arXiv preprint server on June 23.

New Horizons watches the solar wind as it slows down

Where does the solar system end and interstellar space begin? That’s a question scientists have been working to answer using spacecraft traveling beyond the sun’s influence. A team of researchers from the Southwest Research Institute, led by Heather Elliott, is using the Solar Wind Around Pluto (SWAP) instrument aboard New Horizons to track the solar […]

‘Cosmic wallflowers’ may hold the key to the origin of globular clusters

Astronomers using computer simulations have investigated whether a class of star clusters nicknamed “cosmic wallflowers” could be the long-sought ancestors of the globular clusters we see orbiting galaxies today. Their paper, posted to the arXiv preprint server on June 25, suggests that where a cluster is born and how fast it spins may determine its […]

It’s disturbingly easy to trick AI into seeing aliens, say researchers

Are we alone in the universe? Consider mysterious “extraterrestrial” radio signals. Unexplained gases on other planets. Things mistaken for UFOs.

How an interstellar comet sheds light on universe’s ‘cosmic noon’

Last year, an interstellar traveler entered our solar system. Some speculated that it was an alien spacecraft, but it turned out to be a comet, 3I/Atlas, and it provoked interest from astronomers and astrophysicists eager for insights into galaxies far, far away. Detailed observations from the National Aeronautics and Space Administration (NASA) shot down the […]

A new net-membrane could clean up some tricky space debris

We’ve reported on all kinds of wacky ideas for capturing and deorbiting space debris safely. From electric tethers to lasers, engineers and scientists have been trying everything they can think of to deal with the ever-increasing orbital debris problem. But one simple design keeps popping up over and over again—a net. A new paper from […]

The square kilometer array will revolutionize the hunt for alien life

With new technologies come new opportunities. And that is especially true in astronomy—with every new advanced telescope, we have the potential to see (or in some cases, listen) farther and more clearly than ever before. That is certainly the case for the new Square Kilometer Array (SKA), which is currently undergoing a multiyear rollout phase. […]

Canadian Artemis II crew member to retire from space agency

The Canadian astronaut who was part of the historic Artemis II crew that successfully voyaged around the moon earlier this year is retiring from the nation’s space agency, officials said Monday.

Astronomers spot an extremely rare galaxy mega-merger

Scale in the universe is hard to understand from a purely human perspective. Many times, the math just doesn’t sit well with our brains, which evolved to capture and process data about the world around us rather than grok the complexities of stellar dynamics and galaxy mergers. But every once in a while, astronomers find […]

Discrepancies in AI lunar crater catalogs discovered

A new Southwest Research Institute-led study compared eight AI-generated lunar crater catalogs, discovering that many of their published performance metrics drop sharply when the databases are evaluated using the same scientific standards humans are held to. Crater catalogs provide a comprehensive record of impact craters on planetary surfaces. They log the precise location, dimensions and […]

Japan releases snowman-like asteroid image after flyby

Rare images taken by a Japanese space probe during a flyby of a near-Earth asteroid have revealed that the space rock resembled a snowman, scientists said Monday.

Astronomers characterize ‘improbable’ system shaped by brown dwarf

In the course of studying planets beyond our solar system (6,316 confirmed exoplanets and counting), scientists have discovered some very interesting systems. Consider TOI-201, a compact system populated by three bodies, including a brown dwarf, orbiting on the same plane. The system was recently observed by an international team led by the European Southern Observatory […]

Webb uncovers dust-shrouded heart of Centaurus A after galaxy clash 2 billion years ago

In new images from NASA’s James Webb Space Telescope to celebrate its fourth science anniversary, a familiar galaxy transforms into something far richer and far more complex than ever seen before. Webb’s unprecedented sensitivity across near- and mid-infrared wavelengths cuts through the thick lanes of dust that obscure Centaurus A’s center in visible light, showing […]

A last dance before death: Binary stars and the origins of interacting supernovae

When massive stars die, they unleash some of the most powerful explosions in the universe. Yet not all supernovae are created equal. Some continue to shine brightly for months or even years as their expanding debris crashes into dense clouds of gas surrounding the star. These spectacular events, known as interacting supernovae, have puzzled astronomers […]
