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

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.

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

The multi-institutional survey triples the number of dwarf galaxies surveyed for satellites, the researchers report in The Astrophysical Journal. The study identifies 355 candidate satellite galaxies, ...

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 ...
