British-based scientists have recreated the conditions around black holes using a water bath, shedding new light on the extraction of energy from the astronomical phenomenon. Matthew Stock reports. Continue reading
Scientists say they can now “hear the universe” at a news conference in which they confirmed they have detected gravitational waves, a landmark discovery.
NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) recently caught a glimpse of five of these secluded beasts. While hidden from view from most other telescopes, NuSTAR can spot them by detecting the highest-energy X-rays, which can penetrate through the enshrouding gas and dust.
NASA scientists believe the gravitational pull of black holes in the galaxy is causing dark matter to smash together at such high intensity that it is emitting gamma-ray light.
(Next Media) – The discovery of a giant black hole which is growing faster than usual challenges our current theories of black hole expansion.
