Astronomers from the Chinese Academy of Sciences (CAS) have employed the Lijiang 2.4-m telescope to perform optical photometric and spectroscopic observations of a core-collapse Type IIP supernova ...

When a star in the nearby galaxy NGC 2146 exploded in late 2024, it barely registered by supernova standards. The blast, cataloged as SN 2024abfl, was roughly 100 times fainter than a typical stellar ...

Core-collapse supernovae denote the violent deaths of massive stars, typically above eight solar masses, triggered when iron core fusion ceases and collapse ensues. The rebound of infalling layers, ...

GRB 250314A is an ancient cosmic cataclysm caught by JWST's keen infrared eye. And it appears a lot like those that happen ...

Add Yahoo as a preferred source to see more of our stories on Google. New simulations show fast flavor conversion can either help or hinder core-collapse supernova explosions. (CREDIT: AI-generated ...

Once charted as a 'guest star' in ancient China, dreaded as a harbinger of ill omens in medieval Europe, and preserved in the narratives and artworks of Indigenous cultures, these cosmic spectacles ...

For decades, physicists have searched for one of the faintest signals in the cosmos: a background of neutrinos released by ...

A dying massive star does not go quietly. Its core collapses, matter crashes inward, neutrinos pour out in staggering numbers, and somewhere in that turmoil the blast either rebounds into a supernova ...
