Wolf-Rayet Star 124: Stellar Wind Machine

有些恆星在慢動作中爆炸。 罕見的大質量天狼射線星是如此洶湧和炙熱,以至於它們正在我們的望遠鏡前緩慢地解體。 熾熱的氣體球通常比地球質量大 30 多倍,正在被猛烈的恆星風排出體外。 狼射線恆星 WR 124 就在特寫圖片中心附近可見,橫跨 6 光年,正在形成被稱為 M 1 - 67 的周圍星雲。 至於這顆恆星在過去的兩萬年裡為何會緩慢地自爆,仍是一個研究課題。 WR 124 位於 15000 光年之外的箭座(人馬座)。 任何一顆狼射線恆星的命運都可能取決於它的質量,但許多狼射線恆星被認為會以壯觀的爆炸(如超新星或伽馬射線暴)結束自己的生命。 探索你的宇宙隨機 APOD 生成器
原文:Some stars explode in slow motion. Rare, massive Wolf-Rayet stars are so tumultuous and hot that they are slowly disintegrating right before our telescopes. Glowing gas globs each typically over 30 times more massive than the Earth are being expelled by violent stellar winds. Wolf-Rayet star WR 124, visible near the featured image center and spanning six light years across, is thus creating the surrounding nebula known as M1-67. Details of why this star has been slowly blowing itself apart over the past 20,000 years remains a topic of research. WR 124 lies 15,000 light-years away towards the constellation of the Arrow (Sagitta). The fate of any given Wolf-Rayet star likely depends on how massive it is, but many are thought to end their lives with spectacular explosions such as supernovas or gamma-ray bursts.
