Giant Metrewave Radio Telescope


  1. Astronomers have used an Indian telescope to discover the most distant radio galaxy ever known, located at a distance of 12 billion light-years
  2. The galaxy is from a time when the universe was only 7% of its current age
  3. The galaxy is perceived as it looked when the universe was only a billion years old
  4. It was found using the Giant Metrewave Radio Telescope (GMRT) in Pune

About Giant Metrewave Radio Telescope

  1. GMRT is an array of thirty fully steerable parabolic radio telescopes of 45-metre diameter
  2. It is operated by the National Centre for Radio Astrophysics

About Radio galaxies

  1. Radio galaxies are very rare objects in the universe
  2. They are colossal galaxies with a supermassive black hole in their centre that actively accretes gas and dust from its surroundings
  3. This activity initiates the launch of high-energy jet streams, which are capable of accelerating charged particles around the supermassive black hole to almost the speed of light
  4. The discovery of such galaxies at extremely large distances is important for our understanding of the formation and evolution of galaxies.
