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

American astronomer Edwin Hubble (after whom the Hubble Space Telescope is named) coined the term “Local Group” for the galaxies he had identified as moving through space with the Milky Way. The term ...

The Milky Way isn't just drifting through a giant void in space untethered, but is embedded in a sheet of dark matter like a blueberry in a pancake, new research suggests. An analysis of how galaxies ...

"This is useful to uncover leftovers from galactic interactions, constraining the hierarchical process of cosmic structure formation." When you purchase through links on our site, we may earn an ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. When will the Milky Way collide with the Andromeda Galaxy?

Ultra-faint dwarf galaxies orbiting the Milky Way are cosmic fossils. New simulations reveal how these tiny systems reflect early Universe conditions and why some galaxies grew while others didn't.

Satellite galaxies are low-mass companions bound to more massive host galaxies within a common dark matter halo. In the Local Group—dominated by the Milky Way and Andromeda—these satellites exhibit a ...

A cosmic dance could be the future of the Milky Way as it tracks a course to collide with neighboring galaxies, a University of Queensland survey has found. The paper is published in the Monthly ...

A high-resolution colour image showing the central galaxies NGC5713 and NGC5719 taken by the Hyper Suprime-Cam at the Subaru telescope in Hawaii. A cosmic dance could be the future of the Milky Way as ...
