CID-42 (also known as CXOC J100043.1+020637[4]) is a galaxy quasar about 3.9 billion light years away in the constellation Sextans.

It has a distinctive trail of stars extending many light years.

The black hole then recoiled from the gravitational waves produced by the merger and is being ejected out of the galaxy at several million miles per hour (~2000 km s−1).

[1][6] Once ejected it is expected to shine as a displaced quasar for 10 million to 10 billion years until it exhausts its fuel and is no longer recognizable as a quasar.

[7] JWST NIRCam observations were able to rule out the gravitational wave producing recoiling black hole sencario.
