The universe is ancient and vast it is about 13.7 billion years old. And from the day of its formation, the universe is continuously expanding. The universe is full of planets, stars, black holes, nebulae, galaxies, exoplanets.
Astronomers on Thursday announced the discovery of a massive structure. This structure is about 300 times the Milky Way. European Southern Observatory (ESO) spotted six galaxies trapped in a spiderweb-like structure around a supermassive black hole. This structure is less than 1 billion light-years away from the Earth. There may be more similar structures in the universe.
A black hole is formed when a massive star expires. When a star dies in a supernova explosion it either creates a neutron star or if the star is massive then it creates a black hole. These black holes feed on the star clusters. The spider web structure of galaxies contains enough gas within to feed the black hole to turn it into a supermassive giant. Our Milky Way also has a supermassive black hole at the center and it is about 4 million times the mass of the sun and about 14.6 million miles in diameter.
