That discovery also confirmed Einstein's theory.
Anonymous to the public just days ago, a USA 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. Of course, this wasn't an easy task.
The image is the result of a massive collaboration involving the efforts of hundreds astronomers from all over the globe.
The measurements are taken at a wavelength the human eye can not see, so the astronomers added color to the image.
Black holes gobble up anything in their vicinty, even light.
Black holes are monstrous celestial entities exerting gravitational fields so vicious that no matter or light can escape. The methodology had to be rethought from the get-go.
Black holes are "like the walls of a prison".
As researchers explained, while the black hole itself cannot be seen because no light could escape its gravity, one can see a black hole'sshadow produced by the event horizon.
KUALA LUMPUR, April 11 ― Kevin Koay Jun Yi from Penang has the distinction of being among the first team of global scientists to have captured the firstimage of a black hole ― an astronomical achievement that is making waves worldwide since its release yesterday.

Black holes are extremely tricky to spot, owing to their distance from the Earth, and hence, their tiny visible size.
Their lack of light has made them hard to study - and very hard to document. This black hole is an almost-unimaginable 6.5 billion times the mass of the Sun.
The black hole observed by the scientific team resides about 54 million light-years from Earth. It also helps to unlock the mystery of black holes. These telescopes operated as if they were one giant instrument that's the size of Earth. The Significance Of A Photo More than just historical value, the photo of the black hole is an important step forward in continuing to study space.
The implementation involved a technique called Very-long-baseline interferometry, where a virtual dish is created by employing multiple dishes.
"Just a couple of years later, Karl Schwarzschild - he was a German astronomer who was stationed on the Russian front in World War One and was charged with calculating artillery trajectories - somehow gets ahold of Einstein's manuscript and realises something awesome". With the tech in place, scientists then had to figure out the best time to conduct the search simultaneously. It is more than six times bigger than the sun. Researchers are picky at the start of the experiment, but by the end of it, they will scavenge whatever they can. But creating an image of the black hole required a telescope quite a bit larger.
How can the astronomers a picture of a Black hole? The second one is situated in the heart of Messier 87. Another was at the South Pole.
The major discovery provides visual evidence of the existence of black holes and pushes the boundaries of modern science. NASA's Chandra X-ray Observatory, Nuclear Spectroscopic Telescope Array, and Neil Gehrels Swift Observatory space telescope missions all participated as well as NASA's Fermi Gamma-ray Space Telescope.
If the data is collected at the same time, scientists can use it to produce an image.
The Bruins also won three out of four games this season, though the last time these two teams played was back on January 12. A series that went to Game 7 a year ago will see the majority of the main players return for both clubs in the rematch.

If you can beat them by scoring a lot of goals you have to do it, because they have a great team and have great history. It's probably also a good thing for United to have the first leg at home.
