Dark matter makes up most of the mass in galaxies and galaxy clusters. In fact, scientists estimate that ordinary matter makes up only about 5% of the universe, while dark matter makes up about 27%.

Scientists have chilled SuperCDMS detectors to near absolute zero in order to find dark matter that makes up 85 percent of ...

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 ...

A near invisible realm. The post Hubble Spots Bizarre Galaxy That Appears to Be 99.9 Percent Dark Matter appeared first on Futurism.

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.

An unexplained glow that appears to emanate throughout the Milky Way’s outer regions could be our first hint of what dark matter is made of, but astronomers say it is too early to know for sure. Dark ...

Astronomers have just identified what appears to be a cosmic anomaly: a faint galaxy with so few visible stars that, according to calculations, as much as 99.9 percent of its mass is dark matter. The ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

Six thousand eight hundred feet below the floor of an active nickel mine in northern Ontario, something has gone extremely cold. Not cold in the way of a walk-in freezer, or a liquid nitrogen tank, or ...

If dark matter particles decay, then scientists could hunt for signs of this process, including X-ray or gamma-ray radiation or even emitted "ghost particle" neutrinos, in vast clusters of galaxies.
