Rubin Observatory Uncovers Two Previously Unknown Milky Way Satellite Galaxies

Early data from the new NSF-DOE Vera C. Rubin Observatory in Chile has led to the discovery of two previously unknown satellite galaxies orbiting the Milky Way. This initial success suggests the observatory's upcoming 10-year survey will significantly expand the census of our galaxy's faintest companions, offering new avenues to study galaxy formation and the nature of dark matter.
