             Quasars emit energies of millions, 



Quasars emit energies of millions, billions, or even trillions of electron volts. This energy exceeds the total of the light of all the stars within a galaxy. The brightest objects in the universe, they shine anywhere from 10 to 100,000 times brighter than the Milky Way.

Quasars are capable of emitting hundreds or even thousands of times the entire energy output of our galaxy, making them some of the most luminous and energetic objects in the entire universe," according to NASA. For instance, if the ancient quasar 3C 273, one of the brightest objects in the sky, was located 30 light-years from Earth, it would appear as bright as the sun in the sky. (However, quasar 3C 273, the first quasar to be identified, is 2.5 billion light-years from Earth, according to NASA. It is one of the closest quasars.)

The Backwards Moon🌒🌒 Triton orbits Neptune in what is known as a retrograde orbit. This means that it orbits Neptune a direction opposite the planet's rotation.
