Black hole: 29-years old algorithm behind the image

It was the 29-year-old Katie Bouman, who led the development of the algorithm and the program that made it possible to put together data from astronomical telescopes around the world to the first, historical picture of a black hole.

The black holes studied Sagittarius A* in the Galactic centre and an even bigger black hole in the center of the galaxy Messier 87, 57 million light-years away in the constellation of Virgo.

but the image appears in relief against a halo of light and particles in the so-called händelsehorisonten, the limit for how close the light can get before it is sucked in by gravity.

the Image has pusslats together by gigantic amounts of data from astronomical telescopes in several locations on the earth.

Just to transport the large number of hard drives that you needed was a project.

Katie Bouman the theory behind the method in order to assemble the picture.

" You would have needed a telescope as large as the entire earth to get a picture of the black hole. But by using the telescope are at different locations and combine data from them when the earth rotates, we could simulate a telescope as large as the globe, " she says.

an advanced jigsaw puzzle – on the basis of the data collected and the data was missing. Through a variety of uteslutningsmetoder were sorted and compared the pieces with other images from space, until a probable picture of the black hole appeared.

One of the companies on the teknikuniversitetet MIT has tweeted a photograph of Katie Bouman when the image for the first time be created on her computer. https://twitter.com/MIT_CSAIL/status/1116020858282180609

”Look klentroget when the first ever picture of a black is to be reconstructed,” she writes in the same picture on his Facebook page.

In another tweet, which shows Katie Bouman with all the hard drives with the data from the telescopes, comparing her with the legendary Margaret Hamilton, one of the pioneering programmers behind the apollo mission. https://twitter.com/MIT_CSAIL/status/1116007460039483392
