Footprints of Mass Star Migration into The Andromeda Galaxy | NOIRLab

Cosmoview Episode 62: A team of researchers led by astronomers at the National Science Foundation's NOIRLab has uncovered striking new evidence for a mass migration of stars into the Andromeda Galaxy. Intricate patterns in the motions of stars reveal an immigration history very similar to that of the Milky Way. The new results were obtained with the U.S. Department of Energy's Dark Energy Spectroscopic Instrument on the Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory, a Program of NSF’s NOIRLab.
