A potential dark galaxy — one made primarily of dark matter — may have been spotted in the local universe. Dark galaxies are theoretical, starless systems whose discovery could help astronomers better ...

The field of galaxy formation and evolution synthesizes the physics of baryons and dark matter to describe the origin of systems such as the Milky Way and the enormous diversity of the galaxy ...

Add Yahoo as a preferred source to see more of our stories on Google. A dark matter galaxy behaves very differently than a conventional one. (Credit: NASA) A galaxy made of 99.94% to 99.98% dark ...

All galaxies are dominated by dark matter, an invisible "stuff" that outweighs all of the matter comprising stars, planets, and moons by around five to one. But in some galaxies, dark matter takes ...

A team of astronomers have found a mysterious object in the distant universe that could be dark matter or an inactive smaller ...

Astronomers using the Hubble Space Telescope, the Euclid observatory, and the Subaru Telescope have identified a ghostly galaxy in the Perseus cluster that is roughly 99% dark matter, with visible ...

image: Dark Galaxy VIRGOHI 21 has no starlight but radio waves from neutral hydrogen betray its existence. The contours superimposed on this optical image indicate how much gas was detected. This ...

Galaxies with central surface brightness fainter than 26 mag/arcsec 2 are generally known as "almost dark galaxies." They lack an unambiguous optical counterpart and they are usually missed in the ...

Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass. Because it’s so abundant, astronomers believe it should explain many unsolved ...
