In the heart of the milky Way discovered a black hole - scientists

Outbreaks of infrared radiation on the borders of a massive object Sagittarius a*, which conducted surveillance of European scientists have confirmed the presence in the centre of a galaxy supermassive black hole. "Even though [Sagittarius A*] is our closest supermassive black hole, it is still incredibly mysterious".

Earlier this year, astronomers were looking for signs that S2, the star with the closest known orbit to the supermassive black hole thought to be at the center of the Milky Way, might-as predicted by Albert Einstein-deviate from the orbital path proscribed by Newtonian gravity.

An worldwide team of scientists used the GRAVITY tool mounted on the interferometer the Very large telescope for observations of flashes of infrared radiation coming from the accretion disk around Sagittarius A* is a massive object in the center of the milky Way.

To capture the moment, the team used a GRAVITY instrument on the Very Large Telescope.

Clumps of gas swirling around at about 30% of the speed of light on a circular orbit just outside a four million solar mass black hole. "An incredible sensitivity to GRAVITY enabled us to observe the process of accretion in real time in unprecedented detail". It's a point of no return for any material in that gets too close to the black hole.

"We were closely monitoring S2, and of course we always keep an eye on Sagittarius A*", said Oliver Pfuhl, a scientist at the Max Planck Institute for Extraterrestrial Physics. As they watched, they saw three bright flares traveling around the black hole's event horizon at about 30 percent of the speed of light - around 216 million miles per hour. But these observations mark the first time scientists can confirm their long-held theory. "During our observations, we had the good fortune to notice three bright eruptions around the Black hole - it was a happy coincidence", said lake to the new observations.

The study leader Reinhard Genzel from MPE said: "This has always been one of our dream projects, but we dared not to hope, that it would be so soon realized".

Scientists have shown a black hole in the center of the milky Way, zoom which managed with the help of a supersensitive receiver ESO GRAVITY.
