17 ore fa · The solar dynamo that drives sunspots and solar flares could be located near the surface of the sun scientists find, solving a 400-year-old solar mystery and providing a weird link to black holes.
2 giorni fa · A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
4 giorni fa · The observed black hole is in a system called MAXI J1820 + 070, which is made up of a star smaller than the sun and the black hole itself, estimated at 7 to 8 solar masses.
5 giorni fa · SMART NEWS. James Webb Telescope Detects Earliest Known Black Hole Merger, Just 740 Million Years After the Big Bang. The new observations could help explain how black holes became so...
3 giorni fa · Supermassive black hole (SMBH), a black hole more than one hundred thousand times the mass of the Sun. Nearly every large galaxy has a supermassive black hole at its centre. Active galactic nuclei, such as Seyfert galaxies and quasars, are powered by supermassive black holes.
2 giorni fa · A supermassive black hole (SMBH or sometimes SBH) is the largest type of black hole, with its mass being on the order of hundreds of thousands, or millions to billions, of times the mass of the Sun (M ☉).
5 giorni fa · Using X-ray data to test Einstein’s theory of gravity, their study gives the first observational proof that a “plunging-region” exists around black holes: an area where matter stops circling the hole and instead falls straight in.
