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, potentially one of the strongest candidates for an isolated 'dark galaxy,' containing nearly 500,000 times the sun's mass in neutral hydrogen. The discovery was posted on arXiv preprint server on September 24.
