For years, three cosmic phenomena have puzzled astronomers. An ultradense concentration of matter distorts the light from a ...

Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

From Antarctic deserts to the human gut, scientists are uncovering hidden microbial worlds that could reshape medicine, ...

When an invisible entity making up 85% of the universe's mass stumps the greatest scientific minds of our time, awe is an understandable response.

Scientists have just slashed the potential hiding spaces for dark matter particles. The LUX-ZEPLIN, or LZ, experiment has searched for and ruled out the existence of dark matter particles with a wide ...

The neutrino “fog” is beginning to materialize. Lightweight subatomic particles called neutrinos have begun elbowing their way into the data of experiments not designed to spot them. Two experiments, ...

The James Webb Space Telescope (JWST) has uncovered supermassive black holes when the Universe was barely 500 million years ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

An artist's impression of gravitational waves (red and blue) emitted by a merging pair of black holes, inside a cloud of dark matter. (MIT) We may have accidentally detected dark matter back in 2019.
