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 ...

If the fabric of the universe is a flat, rubbery sheet, Earth is a pothole that bends the fabric of spacetime into a funnel around it. But what would it be like to overcome Earth’s gravity, lift off ...

New research has unveiled images of the universe in its infancy—a mere 388,000 after the Big Bang. The snaps of the universe were produced by the Atacama Cosmology Telescope collaboration (ACT), which ...

The universe — everything in existence — is expanding every second! It's only been about a hundred years that humanity has known this, too — that most galaxies are traveling away from us and the ...

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 ...

Researchers have confirmed three objects spotted with the James Webb Space Telescope in the early universe are galaxies brimming with unexpectedly old stars. Credit: NASA-GSFC / Adriana M. Gutierrez ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

Here’s the story we like to tell about the beginning of the universe. Space is expanding evenly everywhere, but if you rewind that expansion you find that all of space was once compacted in an ...
