In case you don't know, a black hole is an area in space, in which gravity is so strong that light simply can not escape. Black Holes are tricky bodies that are hard to recognize as they swallow up the light. It was this mission that brought about giving the first evidence of black holes following quite a while of research. However, Ohio State University's professor Todd Thompson stated that scientists found a huge red star, which seemed to orbit something way smaller to be a black hole in Milky Way.
To locate a hidden black hole, the scientists looked at the Doppler shift of stars and compared this to their brightness over time. The article alluded to a black hole around the giant star 2MASS J05215658+4359220 (J05215658, for short).
This reportedly suggests that there may be a brand new population of black holes that experts have been missing until now.
Generally, a binary system like this - the place a black hole orbits a star is easy to detect, as a result of the black gap's vast gravity pulls material from the sun in, lighting up the black hole with radiation. Astronomers can detect that from Earth. However, stars that are nearby black holes are also different in behavior. That's the case with J05215658.
Even though, there is still every possibility that the black hole could be up to six times as massive as the sun because there is a little bit of uncertainty room built into the calculations. A significant Doppler shift can indicate a strong source of gravity, and when a star's brightness goes up and down in a set pattern, that suggests there is a large object orbiting the star which sometimes blocks its light. When stars die, they have two options for the cosmic afterlife based on their mass: Big stars collapse into a black hole and little stars become a dead, neutron star.
If they really did find a new kind of black holes, we can find out more about the stars that explode, which then form the black holes, which then form neutron stars.
To solve the mystery, astronomers will need to discover similar-sized objects lurking in the cosmos and identify what exactly they are.
