A2744 YD4

A2744_YD4 is a very distant young galaxy. This galaxy has first been identified as a possible distant galaxy in 2015 using Hubble. This detection was made possible because this galaxy lies behind the massive galaxy cluster Abell 2744. In 2017, ALMA observed it and detected a small quantity of dust (the most distant stardust to date) and the first signature of Oxygen emitting light only 600 million years after the Big Bang.
