STARSET_MirrorRare Supernova Relic Found at the Core of Milky Way
NASA’s Chandra X-ray Observatory has discovered the remains of a rare kind of stellar explosion near the center of the Milky Way.
NASA Chandra X射线天文台在银河系中心附近发现了一种罕见的恒星爆炸残骸。
Supernovas are stellar explosions that seed the galaxy with elements vital for life. Sagittarius A East (or Sgr A East) is a supernova remnant that lies near Sagittarius A* — the supermassive black hole in the center of the Milky Way. This supernova remnant is the first known example in our own Milky Way galaxy of an unusual type of white dwarf stellar explosion called a Type Iax supernova, according to a statement from the Chandra X-ray Observatory.
超新星是一种恒星爆炸的产物，它为星系播下了生命所必需的元素。人马座A东(Sgr A East)是位于银河系中心超大质量黑洞人马座A*附近的超新星遗迹。根据Chandra X射线天文台的一份声明，这颗超新星残骸是我们银河系中已知的第一个被称为Iax型超新星的不寻常类型白矮星爆炸的例子。
