Astronomen entdecken Galaxie, von der angenommen wird, dass sie zu 99 % aus dunkler Materie besteht

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 ever found.

CDG-2, which is about 300 million light-years from Earth, appears to be so rich in dark matter that it could belong to a hypothesized subset of low surface brightness galaxies called “dark galaxies,” which are believed to contain few or no stars.
