A new study has uncovered a dozen stellar-mass black holes within 3 light-years of the supermassive black hole at our galaxy’s core — and these might be just the tip of the iceberg.
Citizen scientists have discovered a system of five sub-Neptune planets, NASA scientists follow the spin of Comet 41P, and speedy clouds of gas shed light on the Millky Way's history.
The region around Sgr A*, the 4-million-solar-mass black hole at the heart of our galaxy, is a complex and dynamic place. New Atacama Large Millimeter/submillimeter Array (ALMA) observations of the Milky Way’s center now reveal more about this harsh, inhospitable environment.
Astronomers have transformed star data from the Gaia and Hipparcos missions into a video that predicts stellar motions millions of years from now.
