It's sort of pioneering in many ways, because doing this kind of detailed study of a galaxy at a very high redshift is extremely difficult.
Andrew Benson说，“从多方面看，这都是一种开创，因为对具有高红移的星系做这种详细的研究是非常困难的。”
Such a high redshift indicates the galaxy is 9.3 billion light years away, so we see it just 4.4 billion years after the Big Bang.
这样的一个高红移量表明这个星系距离我们93亿光年，所以我们现在看到的它是宇宙大爆炸44亿年之后的它。
