Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

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

Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown.

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 ...

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.

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.

Now physicists from the University of Washington are taking a big swing at answering that question. All matter exerts gravitational force. The more mass the object has, the greater the force. Yet, a ...

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.

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 ...

A team of researchers proposes a new vision of the Universe's first moments. Their model eliminates the need for traditional speculative hypotheses. Cosmologists have long worked with the inflation ...
