The redshift of this galaxy reaches 9.51 meaning that it was seen when the age of the universe was only 550 million years old. The rate of star formation in it is 10 times greater than the Milky Way
This image shows the galaxy cluster MACS J1149.5 + 2223 taken by the NASA / ESA Hubble Space Telescope. The image in the magnifying square is the distant galaxy MACS1149-JD1, as seen 13.3 billion years ago and recently observed by Alma. The oxygen concentration discovered by 'Alma' is depicted in red.
