英文释义

名词 n.
  1. A powerful and bright explosion of a massive star, which afterwards becomes a neutron star or a black hole, or is destroyed.
    — In these stellar pairings, if the two stars are close together, the white dwarf will siphon mass away from its companion and have an outburst called a nova. And when the white dwarf accumulates too much mass, it will collapse and explode in a supernova. […] “In this kind of supernova, the white dwarf is completely destroyed, so its companion is released and flies off at whatever orbital speed it was originally moving, plus a little bit of a kick from the supernova explosion as well,” Burgasser said.
  2. Something brilliant. figuratively
    — Cornelius was the only one dressed in muscle but collectively they were a bully supernova.
