Answer 11

Galaxies don't emit any energy. Galaxies are just collections of stars, dust, black holes, etc. The stars and what not are emitting energy, but galaxies themselves do not. Other than stars the only energy being emitted by some galaxies is in the form of quasars. Most galaxies have a super massive black hole at the center. When these black holes are actively "feeding" they form a quasar. But many, such as the one at the center of our galaxy, are not an active quasar.

Ah, are you referring to Lyman-Alpha radiation that the Voyager probes just recently detected? This is ultraviolet light emitted by hydrogen atoms as they cool down. This radiation had never been detected in the Milky Way before just because it was drowned out, we knew it was there though.
