Found lurking at the heart of galaxy, a monster black hole

Вокруг черной дыры в центре Млечного пути можно безопасно двигаться

Black holes are objects whose very big is hard to escape the force of the light. The team used the world's largest optical instrument, the European Southern Observatory's Very Large Telescope in Chile, and combined the light of its four 8.2-meter mirrors to get the resolution of a 130-meter virtual telescope using a new instrument called GRAVITY.

According to a statement from ESO, a group of scientists from multiple European institutions observed flares of radiation coming from * a href="*" target="_blank" data-component="externalLink" rel="noopener" *Sagittarius A*, the massive object at the heart of our galaxy.

The flares originate from material orbiting very close to the black hole's event horizon - making these the most detailed observations yet of material orbiting this close to a black hole.

"It's overwhelming to actually be a witness as Material to a supermassive black hole runs with 30 percent of the speed of light around", said scientists Oliver Pfuhl, Max-Planck-Institute for extraterrestrial physics (MPE) in Garching near Munich. Substance for the first time observed so close to the point of no return.

For its in the journal "Astronomy & Astrophysics" published studies, the worldwide team of scientists used the Very Large Telescope (VLT) of ESO in Chile. "An incredible sensitivity to GRAVITY enabled us to observe the process of accretion in real time in unprecedented detail".

Dusk for Dawn: NASA's mission to Vesta and Ceres has ended
It is expected to remain in orbit around Ceres for decades, but will no longer be able to communicate with Earth. NASA has revealed that its Dawn spacecraft's mission has ended due to a lack of fuel.

A video shows a swirling cluster of gas, circling the orbit at approximately 30 percent of the speed of light, just outside a 4 million solar mass black hole.

"We were closely monitoring S2, and of course we always keep an eye on Sagittarius A*", explained Pfuhl. "During our observations, we were lucky enough to notice three bright flares from around the black hole - it was a lucky coincidence!"

"This has always been the project of our dreams, but we dared not even hope that it will become a reality so soon", says Reinhardt, the Ganzel from MPE, who led the study.

This analysis adds further evidence to the long-standing assumption that the black hole residing in the centre of the Milky Way is supermassive.
