Dust, molecules and dynamics of supernovae

超新星爆炸是宇宙中能量最高的事件之一。爆炸在超新星的气体中产生湍流。当超新星年复一年地膨胀，它的气体冷却下来时，超新星遗迹中留下的湍流可以被非常灵敏的望远镜探测到。超新星1987A是400年来探测到的距离最近的超新星爆炸，它以前所未有的细节揭示了超新星遗迹的演化过程。非常灵敏和高角度分辨率的毫米和亚毫米望远镜，ALMA开始揭示这颗超新星遗迹中留下的湍流足迹。这个项目是研究超新星1987A的湍流，并确定30年前超新星爆炸是如何发生的。它将揭示超新星爆炸的巨大能量是如何被利用的。

Supernova explosion is one of the most energetic events in the Universe. The explosion generates turbulence in the gas of supernova. While supernova expands year by year and its gas cools down, the turbulence left in the supernova remnant can be detected by very sensitive telescopes.Supernova 1987A is the closest supernova explosion detected in 400 years, and it has revealed how supernova remnant evolve in unprecedented details. Very sensitive and high-angular resolution millimetre and submillimetre telescope, ALMA began to reveal the footprint of the turbulent left in this supernova remnant. This project is to investigate the turbulence in Supernova 1987A and determine how supernova explosion happened 30 years ago in this supernova. It will reveal how the vast energy of supernova explosion was used.
