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 search for the universe’s center starts with a simple intuition: if everything exploded outward in the Big Bang, there ...

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.

An image showing a computer simulation (more than 50 million light years across) of one possible scenario for the large-scale distribution of light sources in the universe. Andrew Pontzen/Fabio ...

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 ...

The most detailed snapshots so far of the infant universe are confirming that the cosmos consists mostly of mystery material, called dark energy, that accelerates the universe’s expansion. The new ...

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 ...

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 ...
