Signs of a planet transiting a star outside of the Milky Way galaxy may have been detected for the first time.

Scientists have a good estimate on the staggering number of stars in the universe.

The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.

Billions of galaxies are in the universe, with billions of stars in every galaxy. Could billions of planets be out there too?

An odd metallic star called LP 40-365 is hurtling out of the Milky Way galaxy at absurd speed, researchers say. It's "shrapnel" from an exploding star.

New research shows that many stars in the Milky Way galaxy may have Earth-like planets in their orbit. The finding is somewhat at odds with previous work.

Team uses data from space telescopes to create music.

An international team of astronomers, led by the University of Cambridge, announced the most detailed ever catalogue of the stars in a huge swathe of our Milky

Not all planets orbit stars. Rogues float through the galaxy in darkness and are almost impossible to see.

A new method suggests we should aim to detect dark matter haloes by tracing galactic gas.
