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 ...

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, ...

Scientists using the Chandra X-ray telescope have uncovered new details about the famous supernova remnant Cassiopeia A.

Around 11,300 years ago, a massive star teetered on the precipice of annihilation. It pulsed with energy as it expelled its outer layers, shedding the material into space. Eventually it exploded as a ...

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become ...
