GN-z11 is a high-redshift galaxy found in the constellation Ursa Major. GN-z11 is currently the oldest and most distant known galaxy in the observable universe. GN-z11 has a spectroscopic redshift of z = 11.09, which corresponds to a proper distance of approximately 32 billionlight-years (9.8 billion parsecs) from Earth.
The object's name is derived from its location in the GOODS-North field of galaxies and its high Doppler z-scale redshift number (GN + z11). GN-z11 is observed as it existed 13.4 billion years ago, just 400 million years after the Big Bang; as a result, GN-z11's distance is inappropriately reported as 13.4 billion light years, its light travel distance measurement.
关于可观测宇宙的半径为什么不是138亿光年,请移步这篇回答:知乎用户:如何计算可观测宇宙的大小?,或者参考Observable universe | Wikiwand
关于我为啥不翻译,我不觉得这种程度的英语很难看懂,就算看不懂不会查单词么?我有义务翻译给你们看么?
就算我翻译了,你知道什么叫共动距离吗?知道什么叫宇宙学红移吗?知道光度距离是怎么测的吗?难道还要我一个一个名词给你讲?
不愿意看就反对+没有帮助然后关掉啊,非要评论我一下才开心?我以后写回答是不是应该关评论或者开只允许我关注的人评论?

我算是体会到颜宁老师在微博上中英混搭被骂的时候的感受了…… @单衫杏子红
有的人的逻辑很搞笑,题主问的就是这个天体是什么,我给了个答案,附上一段简介,这个简介甚至都不我写的,直接复制粘贴的Wikipedia,请问我哪里装了逼?不爱看就别看啊,题主问了我回答了,你看不懂关我屁事?
