A team of astronomers using the Hubble Space Telescope studied a starless, gas-rich, dark-matter cloud and found it to be a new type of astronomical object—a failed galaxy that never produced stars. Nicknamed Cloud-9, it is a fossil remnant from the early days of the universe.
Scientists have long sought evidence of such a phantom object. But only when they turned Hubble’s sharp vision toward Cloud-9 could they confirm its starless nature—a finding that furthers the understanding of galaxy formation, the early universe, and the nature of dark matter itself: https://news.stsci.edu/4bdj2Ov
