SpaceSpin in this Milky Way bar may show cosmic dark matter does exist
A method akin to studying a tree’s rings reveals the timeline of a slowdown in those stars at the heart of our Milky Way galaxy.

SpaceStars made of antimatter could lurk in our galaxy
Fourteen sources of gamma rays in our galaxy look like they could be antistars — celestial bodies made of antimatter.

PlanetsThe pebbled path to planets
Small pebbles zipping through a sea of gas may give rise to mighty planets.

SpaceHere’s why people picked certain stars as constellations
Patterns of human eye movement help explain why particular sets of stars form iconic shapes, a high school student showed.

SpaceScientists Say: Planet
Planets have to orbit a star, be big enough to form a sphere and keep other objects out of their path around their star.

SpaceRogue planets wander the galaxy all alone
Some planets don’t orbit stars. They were kicked into space long ago. The newest, smallest one found is only about as massive as Earth.
