Astronomers have discovered a stream of stars pulled from Omega Centauri, the largest and most brilliant globular cluster around the Milky Way — and perhaps a one-time dwarf galaxy.
Astronomers are using Gaia and the Hubble Space Telescope to make the most precise measure of the Milky Way’s mass to date. The new result puts our galaxy on par with — if not more massive than — Andromeda.
New measurements from the European Space Agency’s Gaia satellite show that the young stars of the Hyades cluster are beginning to drift apart.
An unexpected pattern in the Milky Way's disk of stars points to a recent whack from another galaxy.
This is what the largest available image of the Milky Way using only off-the-shelf photographic equipment looks like.
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.
