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

Six years after its finale, Star Wars: The Clone Wars remains the creative foundation for modern Star Wars, from The ...

A new study suggests that "little red dots" spied by the James Webb telescope could be the universe's short-lived first ...

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing ...

New 3D map of the early universe from HETDEX reveals faint hydrogen light linking galaxies 9 to 11 billion years ago.

Using the James Webb Space Telescope, an international team of researchers has discovered chemical fingerprints from enormous ...

A closer look at the Lambda Cold Dark Matter model, its core components, supporting evidence, and why new observations are ...

Using gravitational waves as a measure of the universe's rate of expansion could solve the biggest headache in physics, the so-called "Hubble tension." ...

A new study explains how some supernovas are particularly dazzling—the glow from a magnetic, spinning ball of neutrons called a magnetar. An assist from Einstein is what settled the case ...

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 ...

One of the largest known stars in the universe underwent a dramatic transformation in 2014, new research shows, and may be preparing to explode. A study led by Gonzalo Muñoz-Sanchez at the National ...
