The Simons Observatory is one of the most ambitious cosmic observatories on Earth, dedicated to studying the cosmic microwave ...

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 ...

A new look at radio maps of the sky shows a pronounced tilt, called a dipole, that astronomers are still unable to explain ...

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 ...

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 ...

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 ...

Scientists found where the universe’s missing matter went. Black holes have been pushing it far away from galaxies.

UChicago-led study analyzes massive galaxy clusters mapped by the Dark Energy Survey, offers new way to probe cosmic laws ...

He led a team of scientists who helped confirm that a Big Bang was the source of the universe. The discovery earned him a ...

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 ...
