据日本国立天文台网站,国立天文台的团队使用南美智利的阿塔卡马望远镜(ALMA),来观测距离地球1400光年外的猎户座星云中的巨大恒星,此望远镜能捕捉到过去无法观测的微弱电波。刚诞生的恒星是由宇宙中的尘埃与气体不断旋转后聚集而成,由于恒星扩张后离心力变强,周遭就会形成漩涡状的双极外流(bipolar outflow),过去天文学家以理论得出此推测,而也是人类第一次观测到此震撼场景。
而质量大于太阳数倍的巨大恒星,在寿命的尽头将会成为超新星并爆炸,进而产生黑洞,而究竟恒星是如何诞生与成长,这之中还存在许多谜团。研究团队的代表广田鹏也表示:“能清楚观测到让恒星诞生时气体的移动画面真的很让人吃惊,未来会持续研究恒星诞生的巨大结构,希望能解开宇宙的诞生奥秘。”(综编/孙蒙)
