US EditionNASA’s Hubble Telescope Detects Possible ‘Dark Galaxy’
- Astronomers have detected a galaxy called CDG-2 that appears to be made of at least 99.9% dark matter using the Hubble Space Telescope.
- If confirmed, CDG-2 would be one of the most dark matter-heavy galaxies ever found, containing few or no stars.
- Dark matter is invisible and has never been directly observed, but its presence can be inferred due to its gravitational effects on regular matter.

A group of astronomers identified an extremely thin galaxy that can be composed in 99.9% by dark matter, one of the most difficult substances to study in the universe. The discovery, made with data from the Hubble Space Telescope and other observations, opens a new front to investigate how this invisible component dominates the cosmic structure.
Astronomers have detected a galaxy so faint it is almost invisible, a discovery that could help shed light on one of the most elusive substances in the universe.
NASA’s Hubble telescope detects possible ‘dark galaxy’
By Jacopo Prisco, CNN (CNN) — Astronomers have spotted a galaxy so faint, it’s almost invisible — a discovery that could help illuminate one of the most elusive subtances in the universe. The researchers found Candidate Dark Galaxy-2, or CDG-2, using the Hubble Space Telescope, and they believe it’s made of at least 99.9% dark matter. If their finding is backed by further observations, CDG-2 would be one of the most dark matter-heavy galaxies ev…
Astronomers have discovered such a weak galaxy that it is almost invisible — a discovery that could help in the elucidation of one of the most effluent substances in the universe.
Astronomers have identified a galaxy so large that it is almost invisible — a discovery that can help light up one of the most sensitive substances in the universe. Researchers have found the Candidate Dark Galaxy-2, or CDG-2, using the Hubble Space Telescope, and believe that it is composed of at least 99.9% of dark matter. If the discovery is confirmed by new observations, the CDG-2 can be one of the galaxies with greater concentration of dark…
How do you find something that you don't see - even somewhere in the vastness of the universe? Astronomers have done just that: they discovered an almost invisible galaxy that is almost entirely dark matter. (Read more)
