Our cosmic neighborhood may be far more crowded than previous estimates have suggested. New research hints the Milky Way could have many more small dwarf galaxy "satellites" around it than expected.

(CNN) — A collision between our Milky Way galaxy and its largest neighbor, the Andromeda galaxy, predicted to occur in about 4.5 billion years, has been anticipated by astronomers since 1912. But new ...

A long-term survey of small, “satellite” galaxies that orbit larger galaxies across the universe offers new insights into our own galaxy, the Milky Way. Since 2012, the Satellites Around Galactic ...

From your place inside the Milky Way, you are living within a galaxy that keeps a detailed chemical diary. Every star holds clues about when it formed and what the galaxy was like at the time. Over ...
