A stronomers report the discovery of a truly incredible object. They are calling it Candidate Dark Galaxy-2 (CDG-2), a somewhat humdrum name for something truly incredible, a galaxy made almost ...

Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

A team of astronomers have conducted a study that has lifted the veil on a nearly 100 year mystery that explains an odd dark ...

Now physicists from the University of Washington are taking a big swing at answering that question. All matter exerts gravitational force. The more mass the object has, the greater the force. Yet, a ...

Astronomers working with NASA’s James Webb Space Telescope have produced the sharpest wide-area map of dark matter ever assembled, more than doubling the resolution of previous efforts built on Hubble ...

Add Yahoo as a preferred source to see more of our stories on Google. The universe is packed with riddles, but few are as stubborn or as fascinating as dark matter. First proposed in 1933 by ...

The spacecraft bus that will deliver NASA's Nancy Grace Roman Space Telescope to its orbit and enable it to function once there is now complete after years of construction, installation, and testing.

An international research team has found that the Milky Way and its galactic neighbors appear to sit inside a vast, flat concentration of dark matter, a structure stretching roughly 10 megaparsecs and ...

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 ...

Scientists at OIST have, for the first time, directly tracked the elusive “dark excitons” inside atomically thin materials. These quantum particles could revolutionize information technology, as they ...

The reddest galaxies with the largest central bulb show the largest bars -gigantic central columns of stars and dark matter-, according to a scientific study that used Google Maps to observe the sky.
