Day by day, astronomers are discovering new types of black holes. Blackhole forms when a massive star explodes after completing its life period. A black hole is a place where gravity pull is so high that even light cannot pass through it. Gravity pull is high because the whole matter of massive star gets squeezed in the tiny hole. As a light can’t pass through the hole, it appears as a black. In the new research, astronomers discovered a new black whose mass is 70 times than our sun. But according to different stellar black hole studies, this type of massive black hole can’t exist in our galaxy. But according to studies, most of the stars in our galaxy losses their mass at the end of their life due to various factors before collapsing into the black hole. So Scientists are confused about the existing of such a big black hole.
Scientists named this black hole as LB-1. Black holes are tough to detect because they don’t emit measurable radiation & radio waves. English scientist John Michell in 1783, stated one method according to this method if the light-emitting star is orbiting around the black hole, then we can find the existence of black holes and this method is known as radial velocity method. This method is beneficial to find invisible things. Earlier scientists discovered such massive black due to Collison of two black holes. But this black hole is not in our galaxy.
According to some theories, LB-1 is formed by the collision of 2 black holes. Then it captured the light-emitting star. Another possibility is supernova fallback in this dying star explodes & immediately falls into his core. This creates a massive black hole, but this only possible on the paper; there is no practical evidence of it. Astronomers stated that LB-1 might be an example of this theory. This discovery can help the astronomers and scientists to find new black holes in the future.
