This is a historical discovery, as the previous record for the Hubble distance, which occurred in 2018, was about 4 billion years after the Big Bang (by the way, Here is the effect of gravitational lensing observed with telescopes).

The celestial body is located within a huge group of galaxies WHL0137-08. This is where the James Webb Space Telescope will start: the instrument will analyze this group for Learn about the brightness, temperature and composition of Earendel.
