Astronomers using the Hubble Space Telescope, the Euclid observatory, and the Subaru Telescope have identified a ghostly galaxy in the Perseus cluster that is roughly 99% dark matter, with visible ...

Astronomers have detected a ghostly galaxy that is almost completely made of dark matter. The faint object was revealed by just four globular star clusters hiding in the Perseus cluster.

A galaxy made of 99.94% to 99.98% dark matter immediately challenges and updates models for how dark matter works. It also sheds light on how the universe arrived at the large-sca ...
