JADES-ID1 is a galaxy protocluster located around 12.7 billion light-years away from the Milky Way galaxy.[1] Its redshift indicates that it was formed only about 1 billion years after the Big Bang. The space satellite Chandra X-ray Observatory shows that it contains a massive cloud of hot gas. The James Webb Space Telescope found that JADES-ID1 contains a minimum of 66 potential galaxies.[2][3][4][5]
JADES-ID1 lies within the Chandra Deep Field South. This field is part of a deep-sky survey studied by the Chandra X-ray Observatory's satellite.
It has the unusually high overdensity of z ≈ 5.7, indicated that JADES-ID1 a nacent protocluster.
JADES-ID1 emits X-rays and is the earliest protocluster found that has a hot intracluster medium. This stage of cluster formation has never been seen before while the universe was only 3 billion years old.
It has a gravitational mass of approximately 20 trillion solar masses, therefore much to big to be a single galaxy. So, it must contain many galaxies together, all sharing a single gravitational potential. It must have also been in existence long enough to heat up the intracluster gas and start emitting X-rays. This shows substantial gravitational collapse. JADES-ID1 appears to be a bound group that is mature. Models predict this sort of system should only be abundant much later after the Big Bang.[6]
The name JADES-ID1 comes from the survey that observed it, the JWST Advanced Deep Extragalactic Survey (JADES).
