Scientists find the smallest ever black hole

Space scientists have found out a tiny black hole that could collapse under a entirely different class of objects. It has a size of 3.3 solar masses and is situated near a huge star 2MASS J05215658+4359220.

Space scientists seem to have found the smallest black hole ever to get discovered till now that might come under a entirely different class of objects. The researchers at Ohio State University were studying a large star and a companion, which they assert happens to be the smallest black hole ever.

For long, black holes were supposed to exist in two ranges of size. There are black holes that have a mass ranging between five to 30 times that of the Sun and are described as stellar black holes. On the other hand, there are super-massive black holes that having a mass similar to a few million suns.

Now, there is a gap in between these two types of black holes, which scientists accept are filled by black holes which have masses between 100 and 10,000 suns. Such types of black holes are called intermediate-mass black holes, according to a report by New Atlas.

There is a new theory confer to scientists that when the stars break under their own gravity, either they form black holes or energetic neutron stars. There seems to be a limit of 2.1 solar mass under which a break-downing star turns into a neutron star, however, if it is over that limit, then it change completely into a black hole.

The researchers at Ohio State University looked for the black holes that dip in this new category. They looked at a binary star system which is made up by the star 2MASS J05215658+4359220 and its companion. Through a different approach, they found that this especial companion is a likely black hole with low mass. Their research got written in the Science journal.

To look for this hidden black hole, the researchers had to attentively search through the data collected by Apache Point Observatory Galactic Evolution Experiment (APOGEE), which is meant for weighing the light spectra of stars. They were observing the changes in light from stars that may indicate that they are orbiting around some unseen object.
