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

The ESA's Mars Express and ExoMars Trace Gas Orbiter spacecraft watched as a superstorm that ravaged Earth also struck the Red Planet.

The Milky Way nebula RCW 36 resembles a stunning cosmic bird of prey in an incredible Very Large Telescope image.

The galaxy NGC 941 was imaged by the Subaru Telescope at the summit of Maunakea, Hawai'i.

"TIC 120362137 is currently the most compact known 3+1-type quadruple star system."

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."

One of our universe's biggest stars has dramatically turned into a rare, yellow 'hypergiant' star, and astronomers aren't sure when it will go supernova.

"We can study a diverse population of supermassive black holes and their radio jets at different stages of their evolution."

Astronomers have dived into the turbulent and chaotic heart of the Milky Way, discovering hidden chemistry around our galaxy's supermassive black hole.

Astronomers suspect the heart of the Milky Way may be hiding a big secret: a rapidly spinning, highly magnetic, neutron star-powered pulsar.

Using the James Webb Space Telescope, astronomers have investigated 70 dusty galaxies at the very edge of the universe that challenge our understanding of cosmic evolution.

The NASA/JAXA X-ray spacecraft has allowed astronomers to dive into the metaphorical "eye of the storm" swirling around supermassive black holes.

Scientists have discovered that active supermassive black holes don't just kill their home galaxies, but can also eradicate star formation for their neighbors.

Using the Hubble Space Telescope, astronomers have discovered what seems to be a galaxy that is the most heavily dominated by dark matter ever seen.

The investigation could solve the mystery of how supermassive black holes grew so large in the early universe.

"This data provides us with rare insight into how galaxies were transformed in the early universe."

An unusual tidal disruption event spotted by astronomers may be the result of an elusive intermediate mass black hole ripping apart a star.

Scientists have used a novel new approach to discover the potential origins of the sun goddess particle Amaterasu, the second most energetic cosmic ray ever to be detected striking Earth.

Scientists have named two systems of colliding supermassive black holes after Lord of the Rings locations, Gondor and Rohan.

A mysterious object has caused a long-lasting and extreme dimming of a distant star, but is this object a 'failed star' brown dwarf, or an exceptionally massive super-Jupiter exoplanet?

New research suggests that the heart of the Milky Way may be dominated by a dense clump of dark matter rather than the supermassive black hole Sagittarius A*.

"We found an unexpected chemical complexity, with abundances far higher than predicted by current theoretical models."

"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate."

Astronomers used James Webb Space Telescope data to determine the density of the universe's most mysterious "stuff."

"If our hypothesized dark charge is true, then we believe there could be a significant population of primordial black holes, which would be consistent with other astrophysical observations, and account for all the missing dark matter in the universe."
