A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed prior to the dawn of time.

"With the James Webb Space Telescope now revealing more supermassive black holes in the early universe, this mechanism may help bridge the gap between theory and observation."

The eROSITA spacecraft has built the most precise map of soft X-rays over Earth, observing a fascinating phenomenon driven by solar winds from the sun.

Samples of Ryugu returned to Earth by the Hayabusa2 spacecraft show that the asteroid bears the scars of a recent bombardment by tiny space rocks.

Acting as stellar archaeologists, scientists have found fossilized magnetism on long-dead white dwarf stars, which may help to explain how stars evolve.

"Each interstellar comet brings a little bit of its history, its fossils, from elsewhere."

"Most planetary systems appear as 'peas in a pod.' This is not the case in the TOI-201 system."

Astronomers have discovered that jets from a cannibalistic black hole are erupting with the power of 10,000 suns.

NASA engineers have shut down another instrument on Voyager 1 to preserve the power of the most distant spacecraft ever sent into space.

Scientists have used a synthetic universe to observe how the first galaxies evolved and grew. In fact, it is so close to the real thing that it's tricking some astronomers.

The interstellar comet 3I/ATLAS changed significantly as it flew by the sun last fall, astronomers have discovered.

Using the James Webb Space Telescope, astronomers have investigated the giant exoplanet 29 Cygni b — work that could clarify the line between planets and stars.

The Dark Energy Spectroscopic Instrument has completed its five-year mission to build the most comprehensive 3D map of the universe to date — but its exploration of the universe continues.

The Jupiter-bound spacecraft JUICE spotted the interstellar invader comet 3I/ATLAS spraying enough water into space to fill 70 swimming pools a day.

"The discovery of this exceptional object has allowed us to accurately study the nature of the stars at the center of an elliptical galaxy in a remote era of the universe, when the galaxy was still young."

Gravitational waves may have provided the first tantalizing evidence of tiny primordial black holes born during the Big Bang, which could account for dark matter.

"This is the first time we have observed, for a large interval in momentum and for multiple species, this flow pattern in a subset of proton collisions in which an unusually large number of particles are produced."

"It is fascinating that an active galactic nucleus can change its brightness so dramatically over such a short period of time."

Astronomers have discovered that rapidly spinning extreme dead stars or pulsars push it to the edge, blasting out radio signals from their extremities.

Using the James Webb Space Telescope, astronomers have investigated the star-forming region W51, resulting in stunning new images.

NASA's Artemis 2 has launched on a history-making journey around the moon and back, and the moment was captured from space.

The launch of NASA's historic Artemis 2 mission looks incredible in these stunning launch photos.

A Virtual Telescope Project livestream aims to track NASA's Artemis 2 Orion spacecraft — here's how to watch it as it travels through space.

SpaceX Starlink spacecraft was seen prior to breaking up in orbit by a satellite.
