A team of international scientists observing a star in the Milky Way has for the first time confirmed Einstein's predictions about what happens to the movement of a star pbading by. a supermbadive black hole.
Last year 's general theory of relativity predicted that starlight would be extended to longer wavelengths by the extreme gravitational field of a black hole, and that the The star would appear more red, an effect known as the gravitational shift. The first time we were able to directly test Einstein's theory of general relativity near a supermbadive black hole, Frank Eisenhauer, chief astronomer at the Max Planck Institute for Extraterrestrial Physics, said to Einstein's
journalists, he could not think or dream of what we are showing today. "
A team of scientists from the European Southern Observatory began to monitor The Milky Way's central zone uses its Very Large Telescope to observe the movement of stars near the supermbadive black hole 26 years ago [19659007Theblackholeis26000light-yearsfromEarthandhasambadof4milliontimesthesun
Scientists have chosen a star, S2, to follow.With a 16-year-old orbit, they knew that It will return near the black hole in 2018.
For more than 20 years, the accuracy of their instruments has improved and in May 2018, they were able to take extremely precise measurements in conjunction
The orbital speed of the star increased to more than 25 million km / h at the approach of the black hole
The wavelength of the star then stretched that she was trying to escape the gravitational pull. "Odele Straub, of the Observat Paris, tells the story of the supermbadive black hole

Scientists now hope to observe d & # 39; Other theories of the black hole "It's the first step of a long road that the team has been doing for many years and that we hope to continue in the coming years," said Reinhard Genzel of the MEP, who led the so-called national team,
