NASA said CDG-2 “may be among the most heavily dark matter-dominated galaxies ever discovered” ...

The galaxy NGC 941 was imaged by the Subaru Telescope at the summit of Maunakea, Hawai'i.

Astronomers have detected a ghostly galaxy that is almost completely made of dark matter. The faint object was revealed by just four globular star clusters hiding in the Perseus cluster.

Astronomers using the James Webb Space Telescope have spotted the most distant “jellyfish galaxy” ever seen — a cosmic oddity streaming long, tentacle-like trails of gas and newborn stars as it speeds ...

Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass.

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

When you gaze up at the night sky, you’re looking back in time. Light from the stars takes years, sometimes millennia, to reach your eyes. Now imagine seeing light that’s been traveling for 8.5 ...

A newly discovered jellyfish galaxy, seen as it existed 8.5 billion years ago, is challenging assumptions about conditions in the early universe. Astrophysicists at the University of Waterloo have ide ...
