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 ...

Astronomers using the James Webb Space Telescope have confirmed one of the most distant supernova candidates ever studied, revealing the death of a massive star from a time when the universe was only ...

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 ...

A massive star does not always go out in a brilliant supernova. Some instead collapse into black holes, potentially with little or no visible explosion. What determines which path a dying star takes ...

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, ...

Core-collapse supernovae (CC-SNe) represent the final evolutionary explosive phase of sufficiently massive stars. Their characterization consists in understanding the progenitor star’s physical ...

Figure 1: A cross section of the core of a collapsing star. Electron neutrinos (blue arrows) and muon and tau neutrinos (green arrows) are emitted and absorbed within all parts of the core. In the ...

Last year, gravitational wave detectors triggered on what may have been a collision involving a sub-solar-mass neutron star.
