Research led by Southwest Research Institute (SwRI) has integrated three types of machine learning models to generate solar magnetic patches with physical properties and used those as a query to find matching patches in real observations. This elevates generative artificial intelligence (AI) from a means to produce artificial data to a novel tool for scientific […]

Supermassive black holes are among the most enigmatic objects in the universe. They typically weigh millions or even billions of times the mass of the sun and sit at the centers of most large galaxies. At the heart of the Milky Way lies Sagittarius A*, our galaxy’s supermassive black hole, with a mass of about […]

We have been searching for signals from other civilizations for over sixty years. Radio telescopes on Earth have swept the sky, listened patiently, and found nothing but silence. It is a search that demands extraordinary sensitivity and that is the problem. Earth and our very existence itself are getting in the way.

Venus, often called Earth’s twin, is in fact a planet of extremes. Beneath its thick carbon dioxide atmosphere are crushing surface temperatures and dense clouds of sulfuric acid. While the planet’s main cloud layer sits between 47 and 70 kilometers above the surface, scientists have long been puzzled by a mysterious layer of particles below […]

The IBeA group of the EHU-University of the Basque Country is proposing new measures to safeguard the purity of extraterrestrial samples. Several contaminants, including traces of ink, originating in the preparation of subsamples, have been identified in Martian meteorites by the EHU’s research group. The finding highlights the importance of stricter protocols to prevent misinterpretations […]

A study led by UC Riverside physicist Hai-Bo Yu suggests that a new type of dark matter could explain three astrophysical puzzles across vastly different environments. Published in Physical Review Letters, the study proposes that dense clumps of self-interacting dark matter (SIDM)—each about a million times the mass of the sun—can account for unusual gravitational […]

At this point in NASA’s human spaceflight story, researchers have a substantial amount of material—documents, artifacts and images—with which to tell the stories of past flights to space. But with NASA’s Artemis II mission around the moon now in the books, we’re getting a refreshed look at space.

The most realistic picture yet of how galaxies formed and then evolved from the beginning of time has been revealed in a suite of new and unique audiovisual simulations. These data, accepted for publication in the Monthly Notices of the Royal Astronomical Society, show that the standard cosmological model can successfully explain the observed growth […]
