Astronomers Discover Potential Dark Galaxy Using Hubble Telescope

Astronomers have identified a faint galaxy, dubbed Candidate Dark Galaxy-2 (CDG-2), which is believed to consist of at least 99.9% dark matter. This discovery, made with the Hubble Space Telescope, could provide significant insights into dark matter, a substance that dominates the universe but remains invisible. Located approximately 300 million light-years from Earth, CDG-2 may belong to a theoretical class of galaxies known as 'dark galaxies,' which contain few or no stars. The findings suggest that CDG-2 has only 0.005% of the brightness of the Milky Way, highlighting its extreme dimness. Further observations, potentially with the James Webb Space Telescope, are necessary to confirm the extent of its dark matter content and its physical properties.

Key Details: • CDG-2 is located about 300 million light-years from Earth. • It is estimated to have only 0.005% of the brightness of our Milky Way galaxy. • Further observations are needed to confirm the properties of CDG-2, potentially using the James Webb Space Telescope.
