The universe doesn't come with an instruction manual—but if it did, University of Missouri Assistant Professor Charles ...

Two galaxies that closely neighbour the Milky Way are at war, with the larger tearing the smaller galaxy to shreds. The Magellanic Clouds are two dwarf galaxies, visible from the Southern Hemisphere, ...

An analysis of star movements from the Gaia spacecraft reveals that the Small Magellanic Cloud — a satellite galaxy bound to ...

Galaxies may not be as simple as "young and blue" or "old and red." A new idea from astrophysicist Charles Steinhardt proposes a third type: red star-forming galaxies that break the mold. These galaxi ...

Whether a galactic environment has the right conditions for habitable planets to form could depend on how the black hole in that galaxy is rotating.

Looking for a really big story, I naturally headed for "Galaxies in Collision." Bradley Whitmore of the Space Telescope Science Institute in Baltimore brought us up to speed. We've known for a ...

The plasma that makes up the accretion disk comes from farther out in the galaxy. When two galaxies collide and merge, gas is funneled into the central region of that merger. Some of that gas ends up ...
