Black hole sun, won't you come? It all depends on a star's mass before it dies.

Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable 'burping' bouts. Half of all star-killing black holes may experience the same.

The use of atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mysteries of dark energy and dark matter in the lab.

The discovery represents the first evidence that low-mass T.Tauri stars, which are less than 10 million years old, can emit gamma radiation.

So-called 'picojets' spotted by ESA's Solar Orbiter could be feeding high-speed gas outflows from the sun in the form of both energy and matter.

Scientists are still in the dark about what is causing a huge shadowy patch to appear against the blue background of Neptune’s sky.

Also known as "failed stars," brown dwarfs are celestial bodies that sit on the boundary between gas giant planets and tiny stars.

The puzzle of how supermassive black holes grew so large just after the Big Bang could soon be solved.

A century-old mystery of how galaxies change shapes has been solved by considering 'survival of the fittest' collisions between cosmic titans.

Astronomers have found planets that are twice as wide as Jupiter and more than 10 times as heavy, but there's a limit to how big planets can get.

The sun's corona is 200 times hotter than its surface, defying models of stellar bodies. Now, this 80-year-old puzzle may finally have a solution.

Superfast changes to the intensity of a jet blasting out from a small black hole have been detected for the first time.

Astronomers reveal 'the final chapters of a star's life' in a stunning James Webb Space Telescope's image of the exploding Ring Nebula.

NASA has identified a supermassive black hole blasting its energetic jets straight toward Earth. Don't worry, though, this blazar is located 400 million light-years away.

A massive galaxy far from Earth seems to be entirely devoid of dark matter, contrary to all accepted cosmological models.

Ghostly nebulas created by exploding stars appear to align in the Milky Way's bulging center. Astronomers may finally know why.

Three early galaxies discovered by the James Webb Space Telescope could actually be titanic stars powered by a dark matter heart.

A supernova that erupted when a massive star died could have destroyed our infant solar system — if it weren't protected by a cocoon of molecular gas.

Astronomers using the James Webb Space Telescope have discovered a feeding supermassive black hole from when the universe was less than 600 million years old.

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy.

New research looking at the cosmological constant problem suggests the expansion of the universe could be an illusion.

A new analysis of the Jupiter-sized exoplanet WASP-76 b reveals that the world is carrying the remains of its long-lost neighbor in its atmosphere.

The enormous gamma-ray burst, called the Brightest Of All Time (or BOAT), may be powered by its strange jet structure, scientists say.

A new study questions if our planet could capture rocky and icy visitors from outside the solar system — and how scientists could spot them.

A newly discovered supernova can be watched as it develops in real-time online and for free. The livestream will begin at 6:30 p.m. EDT (2230 GMT) on Friday, May 26.
