Supernovae appear to our eyes—and to astronomical instruments—as brilliant flashes that flare up in the sky without warning, in places where nothing was visible just moments before. The flash is caused by the colossal explosion […]

New research led by Southwest Research Institute (SwRI) has confirmed decades-old theoretical models of magnetic reconnection, the process that releases stored magnetic energy to drive solar flares, coronal mass ejections and other space weather phenomena. […]

A Southwest Research Institute (SwRI) review of data collected from near-Earth asteroids Bennu and Ryugu supports the hypothesis that they were originally part of the Polana collisional family in the main asteroid belt between the […]

Since sending the first human into space in the 1960s, the solution to one key challenge has remained elusive: the efficient and reliable production of oxygen in space. On the International Space Station, this problem […]

By analyzing the data from the James Webb Space Telescope (JWST) and the Hubble Space Telescope (HST), astronomers from the University of Wisconsin-Madison and elsewhere have probed the properties of a massive and old galaxy […]

Ursa Major III, the faintest object in our galaxy, orbits the Milky Way at a distance of more than 30,000 light years. Until now, it was considered a dwarf galaxy, thought to consist mainly of […]

Features of spaceflight such as gravitational changes and circadian rhythm disruption—not to mention radiation—take a toll on the body, including muscle wasting and decreased bone density. These may even affect the ability to produce healthy […]

Physicists from the University of Copenhagen have begun using the gigantic magnetic fields of galaxy clusters to observe distant black holes in their search for an elusive particle that has stumped scientists for decades.This post […]

Rising concentrations of carbon dioxide in the upper atmosphere will change the way geomagnetic storms impact Earth, with potential implications for thousands of orbiting satellites, according to new research led by scientists at the U.S. […]

In the not-too-distant future, the search for signs of life on Mars and the moon could see the next generation of robots exploring a new frontier: subsurface lava tubes. These missions could also help us […]
