black hole observing

Our first direct imaging of a black hole. And not any old black hole. This is the heart of the giant galaxy Messier 87.

Katie Bouman was responsible for developing the algorithms for aggregating the data from the fleet of telescopes used around the world.

I like the wide field shot from the Chandra X-ray telescope to get some context.

You can also see the relativistic jet from the black hole.

Check out the detailed blog entry at the Chandra web site.

I also like the diagrams by Alain Marck.

I think they give a good sense of what we're looking at.

See the NASA article for more info.
