Supernova Remnant E0102 from Hubble
影像提供: Hubble Heritage Team, ESA, NASA
Explanation:
It's the blue wisp near the bottom that's the remnant of a tremendous recent supernova explosion. The large pink structure looming to the upper right is part of N76, a large star forming region in our neighboring Small Magellanic Cloud (SMC) galaxy. The supernova remnant wisp, with full coordinate name 1E0102.2-7219 and frequently abbreviated as E0102, also lies in the SMC, about 50 light years away from N76. The above image is a composite of several images taken by the Hubble Space Telescope. E0102 is of research interest because we see it as it appeared only 2,000 years after its explosion. Examination of E0102 therefore gives clues about how an enigmatic supernova works and what materials it dispersed into the surrounding interstellar medium.
說明:
影像底端的藍色絲狀物，是不久之前一次劇烈超新星爆炸的遺骸。影像右上角的巨大粉紅色構造，則是鄰近小麥哲倫星系 (SMC)的大型恆星形成區N76之一小部份。這個超新星所留下的遺骸，完整的座標編錄為1E0102.2-7219，更常被簡稱為E0102，也是位在小麥哲倫星系內，離N76約有五十光年遠。上面這幅組合影像，是由數張哈伯太空望遠鏡影像整合出來的。E0102會成為研究題材，是因為它的視年齡只有二千年。探討E0102有助於了解謎樣的超新星爆炸，以及那些物質會被散佈到周遭的星際介質中。
