A supernova sprays space with many different elements. 超新星会向宇宙放射不同种类的元素。
The researchers found that isotopes from the shock front were mixed into the protosun in a manner consistent with their origin in a supernova. 研究人员发现,激波阵面中的同位素混合到原太阳中,混合方式跟起初在超新星中的时候一致。
A supernova is an astronomical event that occurs during the last stellar evolutionary stages of a massive star's life, whose dramatic and catastrophic destruction is marked by one final titanic explosion. For a short time, this causes the sudden appearance of a 'new' bright star, before slowly fading from sight over several weeks or months.
