Scientists may have identified the gravitational waves that make up some of the universe’s background, not just those coming from unusual events like black hole collisions. New Atlas reports that the ...

The local universe may be expanding more slowly than previously thought, a discovery that could relieve a pesky discrepancy ...

Even when you remove the bright stars, the glowing dust and other nearby points of light from the inky, dark sky, a background glow remains. That glow comes from the cosmic sea of distant galaxies, ...

Astronomers are trying to listen to the universe's background hum — a cascade of gravitational waves believed to exist since the first rapid inflation of space following the Big Bang over 13.8 billion ...

A never-before-seen image of the cosmic microwave background, combining data from the Atacama Cosmology Telescope (ACT) and the Planck satellite, offers a high-definition view of the early Universe.

Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown.

Astronomers across the world announced on Thursday that they have found the first evidence of a long-theorised form of gravitational waves that create a "background hum" rumbling throughout the ...

The fabric of the universe is constantly rippling, according to astronomers who have discovered a background buzz of gravitational waves. These waves may be produced by supermassive black holes ...
