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 ...

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 ...

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

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 ...

The search for the universe's dark matter could end tomorrow—given a nearby supernova and a little luck. The nature of dark matter has eluded astronomers for 90 years, since the realization that 85% ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

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 ...

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 ...

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) ...
