Aspect Details
DiscoveryThe quasi-stellar radio sources (Quasars) were first discovered six decades ago.
DescriptionThese are very luminous objects in faraway galaxies that emit jets at radio frequencies.
LocationThey are located in supermassive black holes, which sit in the centre of galaxies.
FormationQuasars are formed when an event causes a huge amount of gas to pile onto the central supermassive black hole in a galaxy. As the supermassive black hole eats a lot of the gas, it releases ferocious fountains of energy in the form of radiation. This leads to the formation of quasar.
SizeMost quasars are larger than our solar system.
Is a quasar just a black hole?Yes, a quasar is just a black hole. However, it is a supermassive black hole that is growing rapidly by gobbling up huge amounts of gas.

Some important points about J0529-4351

1) It is the brightest and the fastest-growing quasar discovered so far.

2) It is a quasar with a central supermassive black hole accumulating material at the rate of the mass of 370 Sun-like stars per year — about one Sun per day.

3)  It is over 500 trillion times more luminous than the Sun.
