supernova

An enormous gamma-ray burst from a dying star was the most powerful recorded, scientists have said.

Becky Smethurst tells Newsweek a black hole is a couch cushion, "not pulling anything towards them. But if you lose something down the side, it's gone forever."

Scientists have discovered an ultra-bright phenomenon in the distant universe that could have come from a star destroyed by a black hole.

Australia's Astronomical Society has awarded its revered Page Medal to two amateur astronomy projects for the first time in its history.

Prolific star hunter Filipp Romanov, 24, previously discovered 80 variable stars, planetary nebula, and binary stars, but SN 2022bsi is his first supernova.

Images of the Cartwheel galaxy located around 500 million light-years from Earth show a massive star erupting in a supernova that will disperse heavy elements throughout the Universe.

The black hole is stealing material from a companion star, in a process that could show how black holes get a kick from supernova explosions that form them.

The void is located 170,000 light-years from Earth, within one of the Milky Way's satellite galaxies, the Large Magellanic Cloud.

Early Chinese astronomers thought the flashes of light in the sky were stars that appeared briefly then vanished.

The blast emitted more energy than the entire Milky Way galaxy for the short time it lasted and took half the age of the universe to reach us.

Supernovae are cataclysmic explosions that occur during the last evolutionary stages in the life of massive stars.

The last ever explosions will be silent fireworks that take place long after everything else in the universe has died, a study has found.

"This all-sky image completely changes the way we look at the energetic universe," said researcher Peter Predehl.

One suggestion is the star collapsed into a black hole without producing a supernova—a phenomenon that has never been identified in such a large star before.

Betelgeuse a nearby red supergiant star which is up to 20 times more massive than our sun.

The star, named J0740+6620, has a mass more than two times that of our sun, but is just 18 miles wide.

The two balloon-like structures stretch hundreds of light-years and are thought to have formed in a violent eruption seven million years ago.

The snow contained substantial quantities of dust-enriched with iron-60—which isn't naturally produced on our planet.

The exploding star system is located around 7,500 light years away in the constellation Carina (The Ship's Keel.)

These early stars may have blown up in a more violent and asymmetric fashion than previously thought.

On June 16, 201, the discovery of a strange flare in the sky was reported in an astronomical telegram.

Researchers link a supernova explosion 2.6 million years ago to the extinction of marine megafauna.

The supernova may indicate the birth of a neutron star binary system, according to a new paper.

This is the first time astronomers have directly imaged the brutal phenomenon.

Scientists think the star was once part of a binary system until its companion exploded in a powerful supernova, causing it to be blasted off into space.

"When I first saw the Kepler data...my jaw dropped. I said, 'Oh wow!'"

Scientists think Victor Buso's images are the first of their kind.

When massive stars come to the end of their life cycles, they self-destruct in a cataclysmic final explosion.

The explosion occurred thousands of years before the current oldest record of such an event.

These mammoth cosmic engines have transformed our universe.
