【摘要】:正据英国Nature,2013,496:329报道,美国加州理工学院的天文学家小组发现,大爆炸发生后约8亿年时,出现有史以来最大规模的星暴现象,其存在于一个早期宇宙的庞大星系中,星系质量甚至与现在的银河系相当,但恒星诞生的速率却是银河系的2000倍以上,远高于宇宙中任何一个星系。
[Abstract]:A team of astronomers at the California Institute of Technology in the United States reported that about 800 million years after the Big Bang, the largest starburst in history occurred in a large galaxy in the early universe. Galaxies are even about the mass of the Milky way today, but the rate of star birth is more than 2,000 times that of the Milky way, far higher than any galaxy in the universe.
