A new black hole 1,000 light-years away from Earth was discovered by a group of astronomers. This will be the closest celestial neighbor that we have so far. Scientists from the European Southern Observatory (ESO) in Chile ascertained that the cosmic body that they saw is a black hole. They based it through the movement of its neighboring stars, according to the new study published in Astronomy and Astrophysics.
Scientists were trying to pick up the eccentric behavior of the two stars in a system called HR 6819. They are both in the same system and identical in mass and size, but it moves individually. Thomas Rivinius, an ESO scientist who started the study, said: “One of them is rotating very rapidly, so much that it’s almost flying apart ”. Both of the stars are moving through space at different momentum. The astronomers were curious about this two-star system for years. Some of them are thinking that there may be another object nearby, causing the two stars to move differently.
After years of conjecture, Rivinius and his team decided to review with ESO’s La Silla Observatory. The team realized that the stars looked to be orbiting around a celestial object that was about four times or as gigantic as the Sun. But as when they observed it for the first time, there was not anything in the middle of the system, either a star that is hard to see or a black hole. “We could exclude any type of star with that mass being present,” says Rivinius. “So if there’s something with that mass in the system, it must be a black hole.”
Most people are afraid of black holes. But there’s nothing to worry because even though the system is close enough to Earth and can be seen with naked eyes, this black hole is a thousand light-years away and it won’t be a threat to Earth. On the positive side, it is an amazing discovery that there might be even more black holes scattered all over the universe, and even our galaxy.
