And here's the person behind the algorithm that made the picture possible, 29-year-old computer scientist Katie Bouman:


Other sources say that all of the telescopes involved in this amassed 5 petabytes of data. That's a lot of disc space.

The black hole in this caricature would not have reminded me of the brain of Donald Trump but of his sphincter, though some might ask: "Où est la différence"?

The amazing and fascinating thing is that to photograph it the whole earth had to be turned into a telescope. Let me quote from the article:

"In order to image an object as small as Sagittarius A*, you need a really big telescope. In this case, the researchers turned the whole planet into a huge telescope by combining data from eight radio telescopes located all around the world. Using a technique called Very Long Baseline Interferometry, or VLBI, the instruments of all these observatories located thousands of miles from one another were linked to form a “virtual telescope”, whose resolving power is as big as the space between the disparate dishes."

Keep in mind that the by far biggest telescope on earth has a diameter of a bit over a 100 meters (almost 104), so this means that this virtual telescope is about one hundred twenty-five thousand times as big as the biggest telescope on earth.

You can actually see the light bending inward creating a huge lifesaver type of shape around the circumference.   Eerie and amazing, though troubling that it's close enough to photograph.

On the other hand I'm pretty sure that's Sheperd Doeleman's porch light.

No, this is not a belated April fool's joke; scientists really managed to take a photo of a black hole. And here it is:



As you can guess it was extremely hard to get; Sheperd Doeleman, an astronomer at Harvard University and the Harvard-Smithsonian Center for Astrophysics, who directed the project behind the black hole image, said: "... it’s the equivalent of seeing an orange on the moon or being able to read the newspaper in Los Angeles while you’re sitting in New York City”.

The article also mentions that the image looks eerily like the eye of Sauron from "Lord of the Rings", which is a sentiment I share.

And here a link to the whole article:
