無限符號 碰撞星系 發出的光經過83億年才能到達地球
https://www.cnbeta.com.tw/articles/science/1515116.htm 耶鲁大学天文学家彼得·范·多克姆(Pieter van Dokkum)和他的团队在深空中发现了一个非凡的天体,并将其命名为“无限”星系。这个结构实际上是由两个最近相撞的星系组成的,其形状令人联想到无穷大符号。
詹姆斯·韦伯太空望远镜拍摄到的“无限星系”是两个星系发生宇宙碰撞的结果,其形状类似于无穷大符号。这次合并形成了一个新生的超大质量黑洞,以白线为标志,其质量约为太阳质量的100万倍,地球质量的3000亿倍。图片来源:詹姆斯·韦伯太空望远镜和美国宇航局(

研究人员表示,发现一个不在巨大星系核中的黑洞本身就很不寻常。而发现这个黑洞刚刚形成更是史无前例。
“换句话说,我们认为我们正在见证一个超大质量黑洞的诞生——这是以前从未见过的,”范多克姆说。这一发现还对有关早期宇宙黑洞形成的持续争论具有重要意义

Light from this galaxy comes from a time when the universe was only 470 million years old—roughly 13.5 billion years ago
Infinity Galaxy” as captured by the James Webb Space Telescope, is the result of a cosmic collision between two galaxies, forming a shape that resembles the infinity symbol. This merger gave rise to a newborn supermassive black hole, marked by the white line, which is about a million times the mass of the Sun—and 300 billion times the mass of Earth.
