Lone, starless cloud may be a 'dark' galaxy
Astronomers using China's FAST radio telescope have discovered a compact cloud of hydrogen with no visible stars or galaxy around it.
Summary
Astronomers using China's FAST radio telescope have discovered a compact cloud of hydrogen with no visible stars or galaxy around it. This could be one of the strongest candidates yet for an isolated "dark galaxy," containing nearly 500,000 times the sun's mass in neutral hydrogen. The discovery paper was posted to the arXiv preprint server on Sept. 24.
