HD1 is a high-redshift galaxy, which was once a candidate for the most distant known galaxies yet identified in the observable universe. From early data the redshift was estimated of approximately z=13. Followup JWST spectroscopy found it to be an interloper, and is in fact a passive galaxy at a much lower redshift (z = 4.0).
