Astronomers just found a third galaxy without dark matter, supporting a radical cosmic collision theory
astronomers has uncovered a third galaxy devoid of dark matter, challenging conventional wisdom about the invisible substance that is believed to hold galaxies together. Published in a new study ...
These three galaxy images from the AEGIS survey show a range of galaxy types: a disk-like spiral galaxy (top), a cloud-like elliptical galaxy (middle), and an irregular galaxy resulting from a ...
Galaxy formation and evolution dynamics describe the sequence by which primordial density fluctuations in the expanding Universe collapse into dark matter haloes, drawing in baryonic gas that cools, ...
In the vast darkness of the early universe, a spiral of light named Zhúlóng offers a new glimpse into cosmic history. This galaxy, shaped like our Milky Way, formed just a billion years after the Big ...
Ultra-diffuse galaxies (UDGs) are a class of low-surface-brightness systems characterised by large effective radii and diffuse stellar distributions. Despite stellar masses comparable to dwarf ...
Dark matter-free galaxy NGC 1052-DF9 was confirmed by Yale astronomers on June 16, 2026 — the third of its kind ever found ...
