Astronomers may have discovered the closest black holes to Earth | Scientists think two, or even three, black holes could live just about 150 light years from our planet. Space.com #space#astronomy#astrophysics#blackholes
Astronomers uncover details of a massive star, ASASSN-14li, devoured by a black hole, challenging previous theories and hinting at new methods for cosmic exploration.
Pocket book edition of “Light in the Darkness” arrived. The story of the 1st image of a black hole, that I witnessed first hand, but which already started when we first looked at the night sky and wondered about its secrets. You learn a great deal about astrophysics and the philosophical questions surrounding it. It was a #4 bestseller in Germany, has 4.5/5 stars on Amazon and is available in 12 other languages. #astrophysics#BlackHoles#books#bookstodon#astrodon#astrophotography#astronomy
'Twisty' new theory of gravity says information can escape black holes after all: Einstein's theory of relativity say black holes are 'bald', but a new tweak to his research may give the mysterious objects their long-sought 'hair.' #space#spaceexploration#astronomy#physics#blackholes#astrophysics
A University of Kansas survey of a swath of the cosmos using the James Webb Space Telescope has revealed active galactic nuclei (AGN)—supermassive black holes that are rapidly increasing in size—are rarer than many astronomers had assumed previously.
How Did Supermassive Black Holes Grow So Quickly, So Early?
Supermassive black holes are a mystery. These monster black holes with millions or even billions of times the mass of the Sun were already present in the first billion years of the age of the Universe. How did they get enough raw material to grow so quickly? A new study suggests that it all comes down to the giant molecular clouds in galaxies that get funneled into the centers of galaxies during mergers, feeding the hungry black holes. The simulations predict they can grow from millions to billions of solar masses within a few hundred million years.
"I can see my father as he was then, a deep-eyed, deep-skinned, welterweight of a man—broad-shouldered and slim in the waist. At least this is how my four-year-old eyes remember and reenact him, sailing Las Vegas Boulevard, the nose of his ’69 Charger cutting through neon, the clamor of sudden jackpots and cocktails a’ripple in his wake." —Erica Vital-Lazare for The Baffler
New research led by Newcastle University and published in the Monthly Notices of the Royal Astronomical Society has revealed that supermassive black holes obscured by dust are more likely to grow and release tremendous amounts of energy when they are inside galaxies that are expected to collide with a neighboring galaxy.

Could white holes actually exist? (www.space.com)
White holes are mathematically possible, according to general relativity. But does that mean they're actually out there?
