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 ...

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 ...

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 paper is titled "Life in the Bubble: How a nearby supernova left ephemeral footprints on the cosmic-ray spectrum and indelible imprints on life," and it is available on the arXiv preprint server.

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 ...

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 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 ...

Some 2.5 million years ago, viruses in Lake Tanganyika experienced an unexplained explosion in diversity. A new study analyzing iron-60 found in the lakebed suggests that the explosion of a ‘nearby’ ...

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) ...
