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 ...

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% ...

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.

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) ...
