Using VLBI to create an Image of the black hole in the center the Galaxy M87

This video shows the global net of telescopes in the EHT collaboration.
With a process called Very Long Baseline Interferometry they can be combined into a huge, single telescope the size of the earth.
This enables scientists to observe the black hole in the center of for example our galaxy, which is comparable to photographing an apple on the surface of the moon.
As the single telescopes move with the rotation of the earth more and more information about the observed object is gained.
After 24 hours the shadow of the black hole as well as the bright ring of plasma (see ) can clearly be seen.
