There is a naked black hole that sits about 1 billion light-years from Earth in a galaxy named SDSS J1126+2944. Its mysterious origins remain just that – mysterious!

Most of the galaxies in the universe have huge black holes towards their centers. These have clusters of stars around them that are thick in their consistency. However, now astronomers have discovered a black hole that is – so to say – naked.

It seems to have lost its entire accompanying cluster of stars. The finding was announced recently. What remains a mystery is the force that might have broken apart the cobweb of stars.

There is a hunch the astronomers have and it just might be right. An extremely rare medium-sized black hole may be responsible for the clean-up act, but this remains a prediction and is not an established fact.

Since black holes cannot be directly observed, such a hypothesis remains a makeshift belief of science. This black hole is one billion light years away from the earth. It is situated in SDSS J1126+2944, according to Sciencemag.

This is a merger of two galaxies. It was detected in 2014. It consisted of a small object towards one side of the view which had another giant black hole at its center.

The two black holes are separated by 7000 light years. The larger one has 500 times as many stars as the smaller one. There is a possibility that many millions of years ago, when the merger took place, gravitational forces stripped the smaller black hole of its cluster of stars.

But then it might be the case that it began its journey with fewer stars since it is a different kind of black hole.

While supermassive black holes dominate the central points of galaxies, smaller ones are known to exist as well. The larger ones weigh billions of times the mass of our sun, while the smaller ones weigh about ten times the weight of our sun.

Intermediate black holes remain a prediction and they have not yet been detected. Such objects have been observed, that could possibly be these intermediate black holes, but the evidence is flimsy.

The problem seems to be that the Chandra X-Ray Observatory can detect such objects but it doesn’t tell us what exactly they are in their consistency. The latest discovery of a naked black hole is probably an object in a dwarf galaxy.

This may be a hundredth of the size of a normal galaxy. It is too early to make anything out of it. The most science can do at the moment is make a postulate or hypothesis.
