What is a quasar, energy radiated by the large black hole present in this galactic nucleus, where they are found and the quantity of light emitted.
Meaning of the term quasar
Quasars are mysterious celestial objects that astronomers discovered in 1960.
They are sources of light and radio waves, like galaxies.
However, they appear as bright as 200 galaxies together, but much smaller than these.
How can such a small body produce so much light?
Probably a black hole located in the center of the quasar makes it smaller and it emits a strong light before disappearing.
