The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

The Vera C. Rubin Observatory has started releasing its first discoveries: including supernovae, variable stars and asteroids ...

In the name of open science, the multinational scientific collaboration COSMOS has released the data behind the largest map of the universe. Called the COSMOS-Web field, the project, with data ...

Scientists using NASA's James Webb Space Telescope now think the "little red dots" spotted in the early universe could be a new kind of space object. They call it a "black hole star." Credit: T.

The James Webb Space Telescope (JWST) continues to deliver awe-inspiring views of the cosmos and the art world has taken notice. Digital artist Ashley Zelinskie took that inspiration to the next level ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In 1935, ...

Mind-bending materials called quasicrystals have an orderly structure, but without a regularly repeating pattern. They’ve been found in meteorites and the debris from the first atomic bomb test.
