Anonymous to the public just days ago, a US computer scientist named Katie Bouman has become an overnight sensation due to her role in developing a computer algorithm that allowed researchers to take the world's first image of a black hole.
                                               

"I'm so excited that we finally get to share what we've been working on for the past year!" The 29-year-old Bouman, a postdoctoral researcher at the Harvard-Smithsonian Center for Astrophysics, gushed on her Facebook account Wednesday after the image was published.

The term "black hole" refers to a point in space where matter is so compressed that it creates a gravity field from which even light can not escape. The massive black hole in the photo released Wednesday is 50 million light years away at the center of a galaxy known as M87.

While the existence of black holes has long been known, the phenomenon proved to be impossible to witness. 201

6 Bouman developed a algorithm named CHIRP to sift through a real mountain of data collected by the Horizon Telescope project from telescopes around the world to create an image.

The volume of data-four petabytes (4 million billion bytes) – Massachusetts Institute of Technology (MIT) operated by the Massachusetts Institute of Technology (MIT).


To ensure the accuracy of the image, The Harvard-Smithsonian Astrophysics Center, operated by Harvard University, gave the data to four different teams. Each team independently used the algorithm to get an image.

After a month of work, the four groups presented their results to the other teams.

"That was the happiest moment I've ever had [when] I saw all the other teams have images that were very similar, "Bouman told The Wall Street Journal."

"No one algorithm or person made this image," wrote Bouman, who will fall in the beginning. Work as an Assistant Professor at the California Institute of Technology (Cal Tech).

"It required the amazing talent of a team of scientists from around the globe and years of hard work to develop the tool, data processing, imaging methods, and analysis techniques that were necessary to pull off this seemingly impossible feat, "she said on Facebook.

" It has been really a honor and I am so lucky to have had the opportunity to work with you all. "
