Galaxy ESO 376-16 (upper centre), Hubble Space Telescope (HST) image. On the basis of its rather ill-defined morphology, ESO 376-16 is thought to be either a late-type spiral or a dwarf irregular galaxy. Researchers have used the HST to gauge the distance to galaxies including ESO 376-16 by measuring the luminosities of bright red-giant-branch stars in the galaxies. This data was used to produce 3D maps of the distribution of galaxies in that part of the universe. ESO 376-16 is 23 million light years from Earth, in the constellation of Antlia. This optical image was obtained by the HST's Advanced Camera for Surveys (ACS). Image published in 2017.
