Unexpected Rotational Motion Detected in Ultra-Diffuse Galaxies of Hydra Cluster
Astronomers have identified unusual patterns of movement in a class of faint galaxies known as Ultra-Diffuse Galaxies (UDGs) within the Hydra cluster, located around 160 million light-years away. These small and dim galaxies, previously thought to have a random internal motion, have exhibited rotational movement in nearly half of the observed cases. The findings challenge … Read more
