Astronomers have heard the faint hum of gravitational waves echoing throughout the universe for the first time. For nearly a decade, scientists have been hunting for the gravitational wave background, ...

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 ...

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.

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 ...

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.

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 ...

Astronomers have developed a new technique to detect the cosmic ultraviolet background radiation that keeps the universe ionized and hot. Their findings provide clues as to why astronomers observe ...

Astronomers have developed a way to detect the ultraviolet background of the universe, which could help explain why there are so few small galaxies in the cosmos. Astronomers have developed a way to ...

Scientists just got a valuable tool in their quest to understand the cosmic microwave background radiation that persists from the earliest days of the universe. The South Pole Telescope recently ...

General relativity is one of the most successful theories mankind has ever developed, but one of its predictions—the existence of gravity waves—has never been confirmed. Gravity waves are analogous to ...
