Quasars give off huge amounts of energy. They can be a trillion times brighter than the Sun! Astronomers think that quasars are located in galaxies which have black holes at their centers. The black holes may provide quasars with their energy. Quasars are so bright that they drown out the light from all other stars in the same galaxy. The word quasar is short for quasi-stellar radio source. Quasars give off radio waves, X-rays, gamma-rays, ultraviolet rays, and visible light. Most of them are larger than our solar system.
A male Gulf Signal Blenny (Emblemaria hypacanthus) peers from the top of its abandoned mussel hole giving a partial display of its large dorsal fin used both to attract potential mates and fend off competition. Glad I found several these little guys and can’t wait to look for them again soon in the #gulfofcalifornia !
