Astronomers claimed that they have discovered the biggest ever black hole in the small galaxy called NGC 1277 which is situated around 250 million light years away from our planet. This galaxy constitutes the mass equal to 17 billion suns. The biggest ever black hole sits in the NGC 1277 galaxy in Perseus constellation.

This gigantic black hole forms around 14 percent of the mass of host galaxy. When compared with the 0.1 per cent of the usual black hole, this massive black hole adds the mass which is equal to 17 billion suns.

Well achieved.
