A photograph I like

This photo was "taken" on april 10th of 2019 by Event Horizon Telescope Collaboration (EHT), in this photo we can see a black hole, but what is really interesting for me is how they took this photo. I said "taken" because it is not like a simple photo when you taked, this was made with many photos of telescopes around the world, these photos were procesed and complemented by theorical information of blacks holes and after a lot of work this was the result, the first photograph of a black hole in the history.
Also the photo is pretty cool, it is just a red tonaliy very light and dark in a black background. And finally the black holes are incredible objects because nothing can escape from them
