Computer simulations carried out by astronomers from the University of Groningen in collaboration with researchers from Germany, France and Sweden show that most of the (dark) matter beyond the Local ...

Scientists from Argentina’s National University of San Juan say they’ve discovered a “large scale structure” in a largely unseen part of the Milky Way galaxy, according to a new preprint paper ...

When it comes to the Milky Way and Andromeda galaxies, there’s a whole “will they or won’t they” thing going on. In 2012 scientists published their results of Hubble Space Telescope observations ...

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 ...

Tiny galaxies orbiting the Milky Way may hold clues to one of cosmology’s biggest mysteries. Ultra-faint dwarf galaxies are ...

Scientists sifted through a lot of noise to observe a new-to-us galaxy cluster. The cluster is hiding in plain sight behind the massive visual bulk of the Milky Way. To see through the visual noise, ...
