In results presented this week at the 2003 meeting of the American Astronomical Society (AAS) in Seattle, astrophysicist Greg Aldering and colleagues report that their supernova factory project has ...

The Nearby Supernova Factory, an international collaboration of astronomers and astrophysicists, has announced that SNIFS, the Supernova Integral Field Spectrograph, achieved “first light” during the ...

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly ...

Axions are the most likely candidate for enigmatic dark matter that dominates the universe. Astrophysicists are searching for evidence of high-mass axions produced during supernovae. Scientists ...

The Veil Nebula Supernova Remnant. Credit: NASA/ESA/Hubble Heritage Team The most dangerous parts of a supernova explosion are the outputs like X-rays and gamma rays. Even though they only share a ...

NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA ...

A nearby supernova could ruin your whole day. It’s difficult to grasp just how powerful an event the explosion of an entire star is. The energy released as visible light every second by a typical ...

"The best-case scenario for axions is Fermi catches a supernova. It's just that the chance of that is small." When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

After a hot, compact neutron star forms from the collapsed iron core of a massive star, axions should be produced in immense quantities for about 10 seconds. Some of these axions (a, red dotted line) ...
