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 ...

A new study has estimated the universe’s possible age by using precise data on stars.

The researchers said that the "hydroxyl gigamaser" was generated by the merger of two galaxies some 8 billion light-years away.

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.

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.
