宇宙十大暴力事件 彗星把木星撞出“黑眼圈”(2)

恒星的剧痛死亡--超新星爆炸
恒星的剧痛死亡--超新星爆炸
1604年10月9日,德国天文学家约翰尼斯-开普勒(Johannes Kepler)观测发现一种新恒星比其他夜空的任何恒星都明亮。在上世纪40年代,科学家才明白这种恒星实际上是处于暴躁的剧痛死亡,并将其称为“超新星”。此后科学家继续研究当前开普勒发现的这颗超新星,将其命名为“仙后座A超新星”,进一步研究究竟有多少颗恒星最终以这种爆炸形式结束生命。如图所示,这张图片基于美国宇航局“斯皮策”太空望远镜的观测数据,从而揭示仙后座A超新星是以相同的形式的产生爆炸,当它们进入太空时仍保留其外层。
