Currently, the objects with the highest known redshifts are galaxies and the objects producing gamma ray bursts. The most reliable redshifts are from spectroscopic data, and the highest-confirmed spectroscopic redshift of a galaxy is that of JADES-GS-z13-0 with a redshift of z = 13.2, corresponding to 300 million years after the Big Bang. The previous record was held by GN-z11, with a redshift of z = 11.1, corresponding to 400 million years after the Big Bang, and by UDFy-38135539 at a redshift of z = 8.6, corresponding to 600 million years after the Big Bang.
