宇宙十大暴力事件 彗星把木星撞出“黑眼圈”(3)
热核恒星爆炸
热核恒星爆炸
一颗恒星是太阳体积的150倍,它在遥远星系演变成为超新星,许多科学家认为它的爆炸可能性是超大质量恒星的两倍,并且更接近地球。此外,超新星是迄今所观测到拥有更强大能量和最明亮的星体。在此之前,科学家曾认为此类的超大质量恒星很可能会崩溃成为黑洞,或者分解更多的质量,最终成为超密集的中子星。目前,他们知道此类超大质量恒星能以巨热核恒星炸弹的形式变成超新星,这项发现暗示着在银河系内类似的恒星--伊塔星(Eta Carinae)将最终遭遇类似的命运。科学家称,超新星爆炸事件非常明亮,观测者能够较早期地在夜晚观测到超新星释放出的光亮。如图所示,这是超新星SN 2006gy的爆炸过程。
