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…
A faint galaxy has been discovered deep in the universe, where despite the absence of stars, gravity has left a strange mark.
NASA Scientists Found a Nearly Invisible 'Ghost Galaxy' Made of 99% Dark Matter
Astronomers have identified a distant galaxy so faint it barely qualifies as visible. It’s not just the distance part that has researchers squinting to get a better view. Dubbed Candidate Dark Galaxy-2, or CDG-2, the object appears to be composed of at least 99.9 percent dark matter, the invisible substance believed to make up most of the universe’s mass. Detailed in The Astrophysical Journal Letters, the finding is based on data collected from …
At 300 million light years from Earth, the Hubble telescope discovered a "dark galaxy", composed of 99.9% black matter. This discovery questions our understanding of the cosmos and plunges us into the invisible.

slashdot.orgAstronomers Think They've Spotted a Galaxy That's 99.9% Dark Matter
Astronomers have spotted a galaxy they believe is made of 99.9% dark matter, reports CNN - and it's so faint, it's almost invisible: 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....

DePasquale (STScI)] Astronomers using the Hubble Space Telescope have discovered a galaxy, dubbed Candidate Dark Galaxy-2 (CDG-2), located about 300 million light-years away, that appears to be composed of at least 99.9% dark matter. This makes it one of the most extreme examples…
