The universe is mostly a ghost story we don’t understand. Everything we know of, the stars, the planets, and everything on ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it.

The universe is packed with riddles, but few are as stubborn or as fascinating as dark matter. First proposed in 1933 by astronomer Fritz Zwicky, this elusive substance refuses to play by the rules: ...

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.

Dark matter is so pervasive throughout galaxies that its presence explains the stability and motion of stars in systems such as the Milky Way. For example, current models indicate that our galaxy is ...

According to general relativity, gravity is the distortion of spacetime. Heavyweight cosmic entities like stars or galaxies generate enough gravitational force to bend spacetime. When light travels ...

Scientists have just slashed the potential hiding spaces for dark matter particles. The LUX-ZEPLIN, or LZ, experiment has searched for and ruled out the existence of dark matter particles with a wide ...

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 ...

About 85 percent of the matter in the universe is thought to be dark matter, yet there is still no confirmed direct detection of any dark matter particle. Ground-based detectors, space-based ...

A new study suggests that dark matter may consist of particles with different masses. By introducing a two-component self-interacting dark matter model, the researchers show that both the low-density ...

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.
