有些恒星以慢动作爆炸。罕见的、大质量的沃尔夫-拉叶星是如此动荡和炽热,以至于它们就在我们的望远镜面前慢慢解体。炽热的气体球通常比地球大30倍,它们被猛烈的恒星风驱逐出去。沃尔夫-拉叶星WR 124,在图像中心附近可见,因此形成了周围的星云M1-67,直径6光年。为什么这颗恒星在过去的2万年里慢慢地分裂,其细节仍然是一个研究课题。WR 124位于15000光年外的箭座(人马座)。任何一颗沃尔夫-拉叶星的命运可能取决于它的质量,但许多恒星被认为是在超新星或伽马射线爆发等壮观的爆炸中结束生命的。探索你的宇宙:随机APOD生成器

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, is thus creating the surrounding nebula known as M1-67, which spans six light years across. 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.
