About UHZ1

The light we see from it set out 13.3 billion years ago, when the universe was 0.467 billion years old (redshift 10.07).

The map lists it as a quasar / active galaxy and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.

A galaxy with an X-ray-bright black hole seen 470 million years after the Big Bang.

From Wikipedia

UHZ1 is a background galaxy containing a quasar. At a redshift of approximately 10.1, UHZ1 is at a distance of 13.2 billion light-years, seen when our universe was about 3 percent of its current age. This redshift made it the most distant, and therefore earliest known quasar in the observable universe as of 2023.
