Spinning black holes store rotational energy that can be extracted; when a black hole is immersed in an externally supplied magnetic field, reconnection of magnetic field lines within the ergosphere can generate negative energy particles that fall into the black hole event horizon while the other accelerated particles escape stealing …

  Astronomers have discovered about 750,000 quasars, which are among the brightest and most energetic objects in the universe. Despite its uninspiring designation, J0313-1806 is distinct from other quasars. This recently spotted object is the oldest known quasar in the universe, with a supermassive black hole more than 13 billion …

In a new paper in the journal Physical Review Letters, an international team of theoretical physicists described a scenario for the formation of primordial black holes from vacuum bubbles in the early Universe and discussed its intriguing realization that can naturally account for all of the dark matter. ‘Baby universes’ …

  The release of the first-ever image of a real black hole in 2019 was a watershed moment for science, but there’s still more work to do. The Event Horizon Telescope (EHT) team is still planning future observations, but it’s also looking at old data to strengthen our understanding of …

Astronomers using the twin LIGO detectors located in Livingston, Louisiana, and Hanford, Washington, and the Virgo detector located near Pisa, Italy, have detected gravitational waves from the most massive binary black hole merger ever discovered. The two spinning black holes merged when the Universe was only about 7 billion years …
