One of the most remarkable trends in gamma-ray astronomy in recent years has been the emergence of high-energy gamma-ray quasars as an important component of the gamma-ray sky. At gamma-ray energies, these active galaxies are bright;

Quasars are peculiar objects that radiate as much energy per second as a thousand or more galaxies, from a region that has a diameter about one millionth that of the host galaxy. It is as if a powerhouse the size of a small flashlight produced as much light as all the ... Overview of X-ray Astronomy and X-ray sources:

The total energy collected by radio astronomers over the history of radio astronomy amounts to about the energy required for a mosquito to make one "push-up"!! The reason we don't receive lots more radiation is that the sources (e.g., the quasars) are so very far away.
