Astronomers find the Largest Stellar Black Hole

Black Holes and Their Types-

A black hole is an area of such immense gravity that nothing (not even light) can escape from it.

There are three types of black holes- stellar-mass, supermassive and intermediate-mass.

Stellar-Mass black hole: It is created when a massive star collapses under its own gravity. These black holes typically have ranging from about 5 to several tens of times the mass of the Sun.

Supermassive black hole: A supermassive black hole (SMBH) is the largest type of black hole, boasting a mass that is hundreds of thousands to billions of times greater than that of the Sun.

Intermediate-mass black hole: Intermediate-mass black holes (IMBHs) are black holes whose mass ranges between 50 and 50,000 times that of the Sun. Positioned between stellar-mass black holes and supermassive black holes, they represent a middle ground in terms of size.

Why in the News?

Astronomers at the European Space Agency (ESA) recently stumbled upon the largest stellar black hole in the Milky Way, named BH-3. This discovery was serendipitous, occurring during routine data collection from ESA’s Gaia mission when they observed flexibility in the rotation of a star.

About ‘BH-3’ Black Hole-

  • Its mass is 33 times that of the Sun.
  • This black hole is very close to the Earth- at a mere 2000 light-years away.
  • According to the ESA, it is the second-closest known black hole to the Earth.
  • It is in the ‘Aquila constellation’.

The Way Forward-

According to scientific estimates, our galaxy may contain up to a billion stellar black holes similar to “BH-3”. The majority of stellar black holes do not have stars around them, making it difficult to identify them.

The finding of “BH-3” opens the door for more research into these mysterious celestial phenomena while also deepening our understanding of the various populations of black holes in the Milky Way.
