Physicists know that something unseen is sculpting the cosmos, outweighing ordinary matter by roughly a factor of five, yet every detector built so far has come up empty. One of the most audacious ...

The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of ...

Add Yahoo as a preferred source to see more of our stories on Google. The movements of galaxies could reveal the physics behind dark matter. (Credit: NASA) A new study in the journal Nature examines ...

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 ...

Scientists search for "decaying" dark matter (DDM) because it offers unique signatures like specific X-ray or gamma-ray lines or neutrino signals not seen in normal matter, potentially revealing dark ...

Astronomers have shed light on a decades-long debate about why galaxies rotate faster than expected, and whether this behaviour is caused by unseen dark matter or a breakdown of gravity on cosmic ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

A researcher identified gamma ray emissions that appear to have originated from dark matter, but other physicists still aren’t convinced. Reading time 4 minutes Astronomers have spent nearly a century ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using ...

A new study in the journal Nature examines the distribution of dark matter in the universe, attempting to figure out if it obeys the same laws as regular matter. What it found suggests that dark ...
