Scientists may have detected a black hole devouring a neutron star | CBC News

First, astronomers made history when they detected a gravitational wave from two black holes merging. Then it was two neutron stars. Now, astronomers believe they’ve detected a gravitational wave coming from another first-time discovery: a black hole swallowing a neutron star.

How to Understand the Image of a Black Hole – YouTube

We have just seen the first image of a black hole, the supermassive black hole in the galaxy M87 with a mass 6.5 billion times that of our sun. But what is that image really showing us? This is an awesome paper on the topic by J.P. Luminet: Image of a spherical black hole with thin accretion disk Astronomy and Astrophysics, vol. 75, no. 1-2, May 1979, p. 228-235 https://ve42.co/luminet Continue reading

Could the Earth be swallowed by a black hole? – TED Talk by Fabio Pacucci

From asteroids capable of destroying entire species to supernovae that could exterminate life on Earth, outer space has no shortage of forces that could wreak havoc on our planet. But there’s something in space that is even more terrifying than any of these — something that wipes out everything it comes near. Continue reading

How We Know Black Holes Exist?

This video is about the astronomical amount of astronomical evidence for black holes, ranging from x-ray binaries with accretion disks, supermassive infrared-radiating galactic nuclei black holes, orbital characteristics of high mass binaries, and direct gravitational wave detection of inspiraling merging black hole binaries with LIGO. Yes, they’re real. Continue reading
