A team using the NASA/ESA Hubble Space Telescope has uncovered a new type of astronomical object—a starless, gas-rich, dark-matter cloud that is considered a "relic" or remnant of early galaxy formation. Nicknamed "Cloud-9," this is the first confirmed detection of such an object in the universe. The finding, published in The Astrophysical Journal Letters, furthers the understanding of galaxy formation, the early universe, and the nature of dark matter itself.
