A Radio-Loud Quasar, the farthest source of radio emissions, has been discovered by an international team of astronomers with the help of the European Southern Observatory's Very Large Telescope. Astronomers later discovered that most quasars have very low radio emissions, yet are currently known by the same name. They are only found in galaxies, which contain giant black holes that give energy to these glowing disks. Blackholes are holes in space where the force of gravity is so high that there cannot be a transit of light from there. Most active galaxies have a giant black hole at the center that draws nearby objects. Let's know more about Radio Loud Quasar.
