Hace 9 horas · This view, which looks back at galaxies billions of years ago — because it takes that long for such old light to reach us — reveals two galaxies and the black holes at their centers merging ...
Hace 9 horas · These two gigantic black holes and their galaxies consolidated just 740 million years after the universe-forming Big Bang. It’s the most distant detection ever made of merging black holes, scientists reported on May 16. One black hole is 50 million times more massive than our sun.
Hace 9 horas · Hubble View of Green Filament in Teacup Galaxy: Ghostly green filaments in the Teacup Galaxy, illuminated by radiation from a quasar, highlight the active supermassive black hole at its centre. Breathtaking images of black holes captured by NASA's Hubble Space Telescope, revealing the mysterious and dynamic nature of these cosmic giants.
Hace 9 horas · Berlin, Germany (SPX) May 22, 2024. University of Copenhagen astrophysicists have presented evidence that massive stars can collapse into black holes without a supernova explosion. Their study focused on a binary star system, VFTS 243, which suggests that stars can completely collapse under their own gravity.
Hace 9 horas · The infall of matter into the new black hole produces an accretion disk and releases a burst of energy, analogous to the collapsar model. Numerous other models have also been proposed to explain short gamma-ray bursts, including the merger of a neutron star and a black hole, the accretion-induced collapse of a neutron star, or the evaporation of primordial black holes .
Hace 9 horas · Supermassive black holes, found at the centers of most galaxies, have a significant impact on stellar dynamics. The immense gravitational pull of a supermassive black hole can affect the orbits of stars in the galactic center, leading to high velocities and complex orbital patterns.
Hace 9 horas · Wednesday, May 22, 2024 by Indian Defence News. A significant discovery has been made about black holes using the unique abilities of Indian Space Research Organisation’s (ISRO) AstroSat. The satellite, orbiting 650 km above the surface of our planet, has detected aperiodic modulation of high-energy X-ray photons (elementary particles of the ...
