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 ...

Astronomers observed the fading light of supernova SN 2025kg, which followed the fast X-ray transient (FXT) named EP 250108a.

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 ...

If a massive star near Earth exploded into a supernova, the result wouldn’t just be beautiful — it would be catastrophic.

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 ...

The powerful space telescope uncovered 80 early and distant star explosions in a patch of sky the size of a grain of rice. When you purchase through links on our site, we may earn an affiliate ...

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 ...

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

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) ...

Nearly forty years ago residents of Earth were treated to a rare cosmic sight: an exploding star in our sky that was visible to the naked eye. Called Supernova 1987A (SN 1987A), it was the closest ...

An unexpected deep-sea deposit may be the smoking gun from a nearby star that exploded as a supernova in the relatively recent past. Earlier this year, a team of scientists in Germany discovered a ...
