The Antennae Galaxies move closer

An international team including RSAA astronomer Professor Gary S. Da Costa has been studying the Antennae Galaxies and has produced a surprising result. New research on the Antennae Galaxies using the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope shows that this benchmark pair of interacting galaxies is in fact much closer than previously thought - 45 million light-years instead of 65 million light-years.
