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 ...

Ultra-faint dwarf galaxies orbiting the Milky Way are cosmic fossils. New simulations reveal how these tiny systems reflect ...

Add Yahoo as a preferred source to see more of our stories on Google. A simulation of the cosmic sheet as seen from the side, with voids above and below. (Wempe et al., Nat. Astron., 2026) The Milky ...

New simulations show that early ultraviolet light controlled whether ultra-faint dwarf galaxies could form stars.

Astronomers have uncovered evidence that the Milky Way is not drifting through space alone but is embedded in a vast, flat structure of dark matter stretching tens of millions of light-years. The ...

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 ...

A computational model of the early-to-present-day Universe predicts that some of the first stars formed in structures that challenge conventional classification. Read the paper: The emergence of ...

A cosmic dance could be the future of the Milky Way as it tracks a course to collide with neighbouring galaxies, a new survey has found. A high-resolution colour image showing the central galaxies ...
