Using the Subaru Telescope's wide-field camera, astronomers have discovered a previously unknown structure surrounding a tiny ...

The Milky Way was once a textbook example of how a spiral galaxy should form and evolve. Now a wave of new observations and simulations is forcing astronomers to admit that many of those origin ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...
