This is a simulated view of a black hole in front of the Large Magellanic Cloud. The black hole itself appears dark as light cannot escape its limits
The ratio between the black hole Schwarzschild radius and the observer distance to it is 1:9. Of note is the gravitational lensing effect known as an Einstein ring, which produces a set of two fairly bright and large but highly distorted images of the Cloud as compared to its actual angular size.
