A potential dark galaxy — one made primarily of dark matter — may have been spotted in the local universe.
Dark galaxies are theoretical, starless systems whose discovery could help astronomers better understand galaxy formation. The new candidate was found within a large, fast-moving cloud of gas first seen in the 1960s. High-resolution observations of the cloud, reported April 18 in Science Advances, revealed a compact clump of gas that might be a dark galaxy.
“This is the first discovery of a potential dark galaxy in the nearby universe,” says astronomer Jin-Long Xu of the Chinese Academy of Sciences in Beijing.
I guess any living residents of that dark galaxy would also be made of dark matter.
