US, WASHINGTON (ORDO NEWS) — The European Southern Observatory (ESO) in Chile, using one of the world’s most powerful telescopes, discovered a “dancing” star, the possible existence of which next to black holes was predicted by Albert Einstein more than 100 years ago.
Einstein’s general theory of relativity, presented by him in 1915, argued that the orbits in which one object rotates around another do not have to be closed, as in Newtonian mechanics.
A star discovered by astronomers in the very center of the Milky Way, according to a prediction, describes an orbit that resembles a flower in shape, not a classic ellipse.
According to the observatory’s communiqué, this unusual orbit is found in a star that revolves around a “compact radio source,” known as Sagittarius A *.
“This breakthrough in observations confirms evidence that Sagittarius A * must be a supermassive black hole with a mass 4 million times the mass of the Sun,” said Reinhard Genzel, director of the Max Planck Institute for Extraterrestrial Physics and one of the creators of the observatory’s observational program.
The statement also notes that the Sagittarius A * object remote from the Sun for 26 thousand light years and the dense cluster of stars around it provide scientists with a unique laboratory for testing physical phenomena in a previously unexplored mode of extreme gravitation.
