【报道 记者 张阳】哈勃太空望远镜观测到了LHA 120-N 150号星云,星云的组成主要是尘埃和气体,看起如一团云雾,因为星云在塌缩过程中存在角动量,所以在恒星周围还会留下一些绕行的行星和小行星。星云通常被认为是恒星形成的温床,对这一特殊区域的研究能够帮助天文学家进一步了解大质量的恒星是如何形成的

【报道 记者 张阳】哈勃太空望远镜观测到了LHA 120-N 150号星云,星云的组成主要是尘埃和气体,看起如一团云雾,因为星云在塌缩过程中存在角动量,所以在恒星周围还会留下一些绕行的行星和小行星。

星云通常被认为是恒星形成的温床,对这一特殊区域的研究能够帮助天文学家进一步了解大质量的恒星是如何形成的。

这团星云在处理过的图像中呈现出粉红色,周边环绕着许多年轻的行星。欧航局在3月19日发布的一份报告中表示,大质量的恒星形成理论模型认为,它们应该在恒星群内部形成,但是实际观测的结果显示,也有10%的大质量恒星是孤立形成的。

天文学家正在试图弄清楚这些孤立的恒星是单独诞生的,还是在恒星的幼年期就离开了恒星群。现在天文学家正在仔细查看LHA 120-N 150号星云,以确认是否能发现新生恒星和星云中的尘埃团之间的区别。

欧航局表示,只有详细的分析和观测才能揭示太空奥秘的本质,这将有助于最终解决大质量恒星起源的未解之谜

由于天文学家倾向于根据星云与地球事物的相似性来给星云命名,因此从这个星云的形状来看,不知道天文学家是否会给命名为甘蓝蛾云。
