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.

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

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 ...

New observations from the James Webb Space Telescope (JWST) suggest the cosmos may be much older than once believed. For decades, scientists have held that the universe is about 13.8 billion years old ...

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.

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

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 ...

If you look across space with a telescope, you'll see countless galaxies, most of which host large central black holes, billions of stars and their attendant planets. The universe teems with huge, ...

There’s endless debate among cosmologists about what really makes up the emptiness of outer space, though many believe that mysterious stuff that we now call dark matter and dark energy represent a ...

A NASA team using the Hubble Space Telescope found an object in space never recorded before, nicknamed “Cloud-9.” Cloud-9 is a starless, gas-rich, dark-matter cloud considered a “relic” or remnant of ...
