Telescope Discovers most Distant Radio Galaxy

Pune: An Indian telescope to discover the most distant radio galaxy ever known, located at a distance of  billion light years. It is operated by the national Centre for Radio Astrophysics. GMRT is an array of thirty fully steerable parabolic radio telescopes of  45 metre diameter. According to the study, the galaxy is perceived as it looked when it looked when the universe was only a billion years old.

It is also means that the light from this galaxy is almost 12 billion years old. This type of activities is the launch of high – energy streams, which are capable of accelerating charged particles around the supermassive black hole to almost the speed of light.   

Aayush Saxena from Leiden Observatory in the Netherlands said “ It is very surprising how these galaxies harbour surprising how these galaxies have built up their mass in such a short period of  time”.

On the other side, Huub Rottgering also from Leiden Observatory said “ Bright Radio galaxies harbour supermassive black holes. It is amazing to find such objects as early in the history of the universe; the time for supermassive black holes to form and grow must have been very short. Radio Galaxies are very rare objects in the universe. They are colossal galaxies with a supermassive black hole in their centre that actively accretes gas and dust from its surroundings.”
