Unusually fast-moving gas clouds near a nearby galaxy suggest they may have come from outside the galaxy. Scientists have identified high-velocity gas clouds in the nearby spiral galaxy M83, moving at speeds that differ markedly from the galaxy’s normal rotational motion. These unusual velocities su...

NGC 3603-A1 is a pair of giant stars locked in a rapid 3.8-day orbit. Their dynamic relationship provides clues to how massive stars evolve and form black holes. A team of astronomers combined archival data from the Hubble Space Telescope with fresh observations to obtain precise measurements of the...

New simulations suggest globular clusters form in multiple ways and point to a mysterious new type of star system that may already lie hidden in the Milky Way. For centuries, astronomers have tried to explain how globular clusters, among the oldest and densest stellar systems in the universe, first ...
