Just noticed the largest black hole ever!
A black hole happens when a star several times bigger than this sun runs out of nuclear fuel, mainly hydrogen. As it cools it will contract to unimaginable density or gravity, one teaspoon could be in the order of the weight of a whole planet.
Eventually in just a moment the massive and now condensed star implodes into a supernova, from there it becomes a neutron star by the force of even greater gravity. This exacerbation causes even light to become trapped by gravitational pull, both the fabrics of space and time are squeezed.
That area of deformation in nature is called the event horizon, it is the distortion circle you can see in the picture; through there are consumed galactic dust and gas, and entire stars with their family of planets.
Over billions of years they meet and they merge, creating even more massive black hole. And today's discovery is 17 billion times the mass our sun, that's some big monster with an angry appetite!
