The Atacama Cosmology Telescope in Chile has released its final batch of data after 15 years — and it proves that the Hubble ...

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 ...

Astronomers are closing in on a result so statistically secure that, in their language, it borders on certainty: a 99.9999999 ...

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 ...

Final data from the Atacama Cosmology Telescope has ruled out 30 models of the universe, sharpening the Hubble tension and ...

The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us. This marks the edge ...
