For the first time, scientists have built a digital version of the Milky Way that follows the motion of individual stars, not ...

Over the past decade or so, astronomers have speculated about the characteristics of rogue planets in the Milky Way galaxy. These "free-floating" worlds don't orbit stars, but instead roam the ...

The Milky Way has just been reconstructed in unprecedented detail, with artificial intelligence helping astronomers track the ...

The Milky Way keeps its planets close to its chest. Stars in a thin, flat disk bisecting the galaxy have more planets on average than stars in a thicker, enveloping disk — and astronomers now think ...

It's easy to imagine clone armies, lightsabers, and starships on some of these very real planets.
