How a black hole can be so big, with 59% of galactic mass!

Astronomers discovers "The biggest ever black hole" 

Black holes are always an interesting and exciting topic for us. As much as we try to explore them as much they are going to surprise us.

We never had any proper information about these celestial bodies, may be this is the reason that they keep surprising us with time.

The information we know about Black holes are, they are the body of massive mass which possess infinite gravitational force around it.

Black holes form when a star totally consume its fuel of nuclear fusion and unable to fuse further then the balance between its mass and gravitational force disturbed hence star starts collapsing until it convert into a single point of infinite mass and density.

When black hole totally convert into a single point then that point is termed as point of singularity which posses intimate hence it make a big and deep curve in space time which is deeper than curve made by any other object and that point and curve is simultaneously termed as black hole.

Because of such pit like curve, all the  objects are attracted towards that black hole, a hypothetical region around black hole from where no object can escape is known as event horizon.

Once if light entered in event horizon then it also can’t escape from its gravitational pull.

Only these information about Black holes are sufficient to excite any one but the reality is, we haven’t see any black hole yet. The reason behind this is simple, they didn’t reflect light so how can we see them?

We have see a black hole recently but we know they really exist even before because we had detected the proof of their existence because of their gravitational force on the objects near a black hole.

Today we know that there is a super massive black hole in centre of our milky way galaxy named as “Sagittarius A*” (pronounced as sagittarius a star) and not only in our galaxy black holes must present in the centre on each and every galaxy. It may be smaller than the sagittarius A* or may be bigger than that.

In 2012 astronomers discovered a body of huge mass in a galaxy NGC 1277 which is 220 million light years away from us in Perseus constellation.

After rechecking with the same instrument and by changing instrument they confirmed that is a black hole of 17 million solar mass.

According to calculations, this black hole of NGC 1277 have mass of 59 percent of bulge of its galaxy which is equal to 14 percent of the total staller mass of the galaxy where normally black holes are 0.1 percent of mass of the its galaxy.

According to Carl gebhardt of university of Texas, this black hole could be the first object in new class galaxy-black hole system.

The event horizon of this black hole is wider as 11 times the orbit of Neptune around sun, which is really massive.

According to Remco van den bosch it takes a year to calculate and double check the mass of this black hole to submit their research paper to publish.

Some astronomers believe that, the size of central part of this galaxy and its black hole is interlinked between each other.

The closest competitor of this black hole is a black hole in galaxy NGC 4486B which contain 11 percent of bulge mass of its galaxy.

According to Bosch’s team, they have discovered five other galaxies NGC 1277 which also may contain black hole of same size as NGC’s black hole or may be even larger than that. After this discovery, once again black hole surprises us and this time by its size.
