Sakurai's Object has entered a new stage of its evolution with the "born again" star shedding material in a powerful stellar wind extending over a region similar in size to our solar system.

To solve the mystery of strange "Little Red Dot" objects spotted by the James Webb Space Telescope, astronomers have looked at the bigger picture, studying their host galaxies.

The discovery of 50 "ghost" galaxies located up to 100 million light-years away may solve an astronomy puzzle.

Some vampire white dwarfs that feed on companion stars can transform into neutron stars, but like a cosmic Goldilocks, conditions must be "just right" for this extreme makeover.

Using the James Webb Space Telescope, astronomers have discovered that the ring system of the tiny solar system body is even more interesting than they knew.

The sun may have swallowed a super-Earth planet in its early history, and our star may still be hiding the evidence, new research suggests.

A catalog of almost 3,000 white dwarfs that exploded as type Ia supernovas after overfeeding on companion stars indicates that dark energy is changing over time.

Wrinkles on the surface of Mercury have revealed that the closest planet to the sun is shrinking faster than scientists thought.

Though their origins may be shrouded in mystery, fast radio bursts could be used to probe some of the universe's biggest puzzles, including the nature of dark matter and dark energy.

A "forbidden" merger between two black holes may not have been quite as impossible as previously thought. New research that suggests the black holes involved were smaller than first calculated.

Using ALMA, astronomers have watched as two stars come together to form a massive stellar binary, finding chaos that indicates they emerged from different backgrounds.

A photon from the biggest cosmic explosion since the Big Bang, the gamma-ray burst nicknamed "the BOAT," should not have reached Earth, according to Einstein. Now scientists may know how it did.

Scientists may finally know why Venus, Earth's twin, lacks a moon, finding that the hottest planet in the solar system may have consumed its own natural satellite.

Scientists have spotted the first hints that Einstein's formulation of gravity operates in the quantum realm.

Astronomers have used the MeerKAT radio telescope to detect hydrogen gas located billions of light-years away, from a period when the cosmos was billions of years younger.

Scientists are close to understanding how stars forge the elements that comprise our planet, bodies and pretty much everything else around us, and how they explode to distribute these elements.

"This transition, from a spherical cloud to a protoplanetary disk, is one of the most significant events in all of solar system history."

Over massive supermassive black holes too big for early galaxies and detected by the James Webb Space Telescope may not be quite so massive after all.

Using the LUX-ZEPLIN experiment, scientists may have detected the first direct evidence of dark matter, in the form of a rare interaction between a WIMP particle and ordinary matter.

Studying 75 meteorites falling to Earth, scientists have identified the seven stages a space rock goes through as it crashes through our atmosphere.

Some stars encounter supermassive black holes and live to tell the tale. New research shows why the flares these encounters cause dim over repeated episodes.

Astronomers are closer than ever to confirming the discovery of the first starless or "failed" galaxy, packed with dark matter and gas but with virtually no stars.

Using the James Webb Space Telescope, astronomers have studied 72 young sun-like stars to discover that forming planets is a real race against time.

A newly discovered water dominated exoplanet is in hot-water literally and figuratively, it orbits so close to its parent star it is headed to a fatal collision that will see it devoured.
