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。
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。”
GRB with redshift 6.3 has been detected recently, which indicates that GRBs now begin to serve as probes of the high-redshift cosmology.
最近还发现一个红移高达6.3的伽玛暴，这标志着伽玛暴开始成为研究高红移宇宙学的探针。
