An international team of astronomers confirmed the existence of one of the darkest galaxies known to date.The object, called the Dark Galaxy-2 Candidate (CDG-2), is located in the Perseus cluster and was identified thanks to data from the Hubble space telescope and the Euclid space telescope.The study, published in The Astrophysical Journal Letters, describes CDG-2 as an extremely tenuous galaxy whose detection did not begin with its diffuse ste…
Hubble identifies one of darkest known galaxies - 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 NASA/ESA 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 …
Hubble Discovers One of the Darkest Galaxies Known to Exist
Hubble has just discovered one of the darkest galaxies known to exist. It’s named Candidate Dark Galaxy-2, or CDG-2 for short. This faint object is located in the Perseus galaxy cluster, around 300 million light years from Earth. Most galaxies announce their presence with a dazzling display of illumination, but CDG-2 does the opposite, with [...]
"Dark Galaxy" CDG-2 Detected in Perseus
"Dark Galaxy" CDG-2 Detected in Perseus | Hubble Space TelescopeThe low-surface-brightness galaxy CDG-2, shown in this image from the NASA/European Space Agency Hubble Space Telescope, is dominated by dark matter and contains only a sparse scattering of stars. This galaxy is nearly invisible, but by using advanced statistical techniques, scientists identified it by searching for tight groupings of stars called globular clusters at the center of …
What is Candidate Dark Galaxy‑2?
A putative dark galaxy in the Perseus cluster Astronomers have identified a faint object in the Perseus galaxy cluster that behaves like a galaxy but lacks the expected starlight. Designated Candidate Dark Galaxy‑2 (CDG‑2), the object is associated with four compact stellar systems—globular…
