Astronomers spot black hole spinning unbelievably fast as it swallows up a star – BGR

Black holes are some of the most interesting features of our universe, but they're also not very well understood. Studying distant black holes in any great detail is very difficult due to the fact that nothing, including light, can escape their grasp once

Recoil detectives: searching for black hole kicks using gravitational waves | astrobites

Gravitational waves are believed to be able to “kick” black hole merger remnants out of their host galaxy. We can search for signatures of that kick directly in gravitational wave signa…

Gravitational Lensing Provides Rare Glimpse Into Interiors of Black Holes

The observable Universe is an extremely big place, measuring an estimated 91 billion light-years in diameter. As a result, astronomers are forced to rely on powerful instruments to see faraway objects. But even these are sometimes limited, and must be paired with a technique known as gravitational lensing.

Astronomers are set to peer into a black hole and take a picture of its event horizon

Ever since first mentioned by Jon Michell in a letter to the Royal Society in 1783, black holes have captured the imagination of scientists, writers, filmmakers and other artists. Black holes are regions of space inside which the pull of gravity is so st

Lab Tests Find Confirm Hawking Radiation

A whisper from a lab-manufactured black hole may confirm the existence of radiation predicted by University of Cambridge physicist Stephen Hawking four decades ago. If validated by further research, the finding would offer evidence that particles blinking in and out of existence can rob black holes of mass.
