Black Holes Don't Live Forever, But They Might Live Long Enough To Look Like White Holes

Black holes evaporate through Hawking radiation, meaning their days are numbered. But a new study finds they could enter a metastable stage where they look similar to white holes.

Exploding Stars, Black Holes, and the Forbidden Gap

An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe....

The Universe Is Full of ‘Impossible’ Black Holes. Now Scientists Know Why

There are black holes that are too big to be born from the death of a star but aren’t quite supermassive either. There’s finally evidence for where those came from.

When Spacetime Crystallises, a Black Hole is Born

Physicists have thought for decades that microscopic black holes can theoretically emerge not from exploding stars but from delicate "critical states" in which space and time organ...

Tiny black holes: crystals of space and time

Scientists have found a formula describing a strange phenomenon: space and time can form a kind of 'crystal' that may turn into a black hole.

Black holes don't live forever, but they might live long enough to look like white holes

Black holes live forever, at least according to general relativity. Once material crosses a black hole's event horizon, it is trapped forever, until the last day of cosmic time. Bu...

Shredded stars reveal how black holes ignite trillion-sun flares

Supermassive black holes are among the most enigmatic objects in the universe. They typically weigh millions or even billions of times the mass of the sun and sit at the centers of...

Black Hole Jets Pack Power of 10,000 Suns, Stunning New Study Reveals

New observations reveal how black hole jets behave under pressure, offering a crucial benchmark for understanding their role in cosmic evolution. A new study led by Curtin Universi...

Webb reveals black hole that formed before its galaxy

Which comes first, the galaxy or the black hole? We don't know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel an...

"Little red dot" in early Universe is a naked supermassive black hole

The black hole accounts for over two-thirds the mass of the object it inhabits.

Mysterious ‘Red Dot’ Galaxies Could Have ‘Relic’ Black Holes Predating the Big Bang

A new study explains how dense pockets of matter could have survived over an age-old cycle of multiple ‘Big Bangs.’

Two Tiny Galaxies Have Black Holes That Should Not Exist. JWST Is Explaining Why

A Strange Black Hole Mystery Has Stumped Physicists Since 1993. Researchers May Finally Have the Answer

Some black holes could have tamer origins—in the folds of unusual "spacetime crystals" that researchers finally managed to capture in a formula.

Black holes slamming into scorching stars may be causing mysterious blue flashes in the cosmos

Powerful bright blue cosmic explosions called Luminous Fast Blue Optical Transients could be caused when a black hole or neutron star slams into the universe's hottest class of sta...

Biggest black holes built up in busy star clusters after series of violent merging events

Most massive black holes detected via spacetime ripples likely grew from repeated violent collisions in dense star clusters, not direct star collapse.

'Dancing' jets erupting from a cannibalistic black hole have the power of 10,000 suns

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