Astronomers have discovered a mysterious galaxy that emits no visible light. They have found the first dark galaxy in nature. It’s a loner lying 94 million light-years away.
Apart from a small fraction of stars, more than 90% of it is composed of dark matter. At first, the researchers thought it was a regular dwarf galaxy with very few stars. However, a detailed analysis of the galaxy revealed it’s an oddball that defies all expectations. Its properties challenge our understanding of extragalactic astronomy.
Furthermore, this dark galaxy could solve one of the biggest astronomical mysteries, the missing satellite problem.
