NASA’s Hubble Identifies One of Darkest Known Galaxies
Release date: Wednesday, February 18, 2026 10:00:00 AM Eastern Standard Time
The elusive object dubbed CDG-2 may be composed of 99% dark matter.
Most galaxies in the nearby universe are quite luminous. But some are so faint they’re nearly invisible. Astronomers, using the Hubble Space Telescope in combination with other observatories, identified a galaxy that appears to be almost entirely dominated by dark matter with only a smattering of stars. The galaxy, known as Candidate Dark Galaxy-2 (CDG-2), appears to contain just four globular star clusters (compared to the Milky Way’s 150-plus), and dimly shines with the light of only about 6 million Suns.
