Astronomers have uncovered a hidden cosmic web of galaxies and gas by mapping hydrogen light from the early universe.

In this video, we explore the vastness of the universe and attempt to quantify its size. We delve into the concepts of cosmic ...

Despite years of debate and follow-up studies, an odd streak of cosmic light still defies a final explanation. Is it a giant ...

Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.

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

A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and ...

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...

The oldest stars in the Milky Way are forcing a fresh look at one of cosmology’s biggest arguments. If some of them are about ...

Astronomers have created an enormous 3D map of the universe revealing a glowing “sea of light” from hydrogen gas during the cosmic dawn nearly 11 billion years ago.

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples ...

Analysis reveals what appears to be a channel of hot, low-density plasma stretching out from our solar system toward distant ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...
