FAST and Arecibo point to possible dark galaxy with vast hydrogen reservoir
Astronomers have found a vast reservoir of hydrogen with something conspicuously missing: detectable starlight. The object, called AGC 322753, contains roughly 2 billion times the sun's mass in neutral hydrogen, a potential supply of material for making stars. Its radio signal suggests the gas may be rotating in a disk, yet deep astronomical images reveal no matching glow.
