Indian origin astronomer led group dicovers Black Hole 5,000 times vast than our Sun

Some evidence for a new intermediate-mass black hole was discovered by an Indo-American-led team of astronomers from the University of Maryland (UMD) and NASA’s Goddard Space Flight Center. The mass black hole is said to be about 5,000 times the mass of the Sun and will probably be an additional candidate to the list of prospective medium-sized black holes. At the same time, the discovery could provide some strength into the fact that these objects are in-existent.

A similar finding took place in 2014 through a study that precisely measured a black hole that weighed 400 times the mass of the Sun. The study was carried out by some of the same scientists using data from NASA’s Rossi X-ray Timing Explorer (RXTE) satellite.

Nevertheless, according to a post-doctoral associate at the Joint Space-Science Institute, Dheeraj Pasham it is very common to have some doubts about something for the first time.

However, Pasham was quick to state that identification of this second candidate was enough to add some weight to the earlier findings while giving confidence to the technique used. The team used data from the European Space Agency’s XMM-Newton Satellite.

The new mass black hole candidate classified as an ultra-luminous X-ray source known as NGC1313X-1. It is one of the brightest X-ray foundations in the nearby universe even though it has not been easy to expound precisely why ultra-luminous X-ray sources are so bright.

Pasham and his colleagues also recognized two repeating flares as a result of the haphazard X-ray fireworks created by NGC1313X-1.

The two were flashing at an unusually steady frequency, 27.6 and 17.4 times per minute respectively. So far astronomers have not established the cause of these constant flashes though there is the likelihood that it is a result of activity close to the black hole.

Plans are now underway by NASA to unveil a new X-ray telescope called the Neutron Star Interior Composition Explorer (NICER).

Pasham has identified several potential intermediate-mass black hole candidates and is very optimistic about being able to explore them.

In any case, he says that the method they used was purely empirical hence it is not dependent on models and the more reason it is strong.

The study is published in the Astrophysical Journal Letters.


  1. Great achievement from Indian origin scientists. It could have been more happy if we had the same research centers facility to discover things in India.

  2. There is ambiguity in the title of this article. If the the black-hole’s mass is 5000 times the sun,it doesn’t make that black-hole 5000 times vaster than sun. The basic idea of black-hole is “a star collapses on itself after its lifetime”. That is all the mass of a star which is spread over millions of miles in diameter,collapses into a a few hundred miles. It gets so denser that nothing can get out of its gravity,not even light. Discovering a black-hole with more mass has nothing to do with its vastness.

  3. it is 5000 times more mass than sun not vast….. black hole always will be very small compared to stars .but they will be extremely denser.
