Image of Abell 3158, Part of the DESI Legacy Imaging Survey

This is an image centered on a relatively nearby galaxy cluster dubbed Abell 3158; light from these galaxies had a redshift value of 0.059, meaning that it traveled approximately 825 million years on its journey to Earth. The image is a small part of the DESI Legacy Imaging Surveys — a monumental six-year survey covering nearly half the sky. Most of the  data for the image originally were taken as part of the LoVoCCS survey.
