A team of scientists saw how a star quickly pbaded through a black hole, succeeding in illuminating one of the most mysterious places in the universe, inside one. black hole.
After 26 years of observations in a dazzling environment, a star called S2 orbiting this object made its closest pbad, behaving as predicted by the theory of relativity.

This effect was called "red gravitational shift", or red gravitational displacement.
"It was the first time that we could directly prove the theory of general relativity of Einstein near a supermbadive black hole. In the era of Einstein I could not think or dream of what we are showing today, "said Frank Eisenhauer, Chief Astronomer of the Institute Max Planck for Extraterrestrial Physics
. To achieve this impressive scientific result, a group of scientists from European Southern Observatory (ESO) began to monitor the center of Via Lactea using the Vary Large Telescope ] 26 years ago, in order to be able to observe the movement of stars near a supermbadive black hole.
A rather complex observation considering that a black hole is 26,000 light-years from Earth and has a 16-year orbit, so researchers knew that the star would amount to approaching the black hole in 18 years old.
Taking into account the failures they exhibited in the observations, they improved It was determined that the orbital speed of the star increased to more than 25 million kilometers per hour by getting closer to the black hole. . In addition, the wavelength of the star is lengthened as it tries to escape the gravitational pull of the supermbadive black hole, changing of color from blue to red
Françoise Delplancke ] Head of the Department of Systems Engineering at ESO, explains the significance of the observations: "Here in the solar system, we can not test the laws of physics now and under certain circumstances, in astronomy it is very important to check that these laws are also valid where the gravitational fields are much stronger. "
For the For the moment, observations are still in progress and we hope to be able to confirm another relativistic effect very soon.
