Although this water is in ice form, there is a possibility that there is only a crust of ice with a liquid ocean underneath. Because of powerful thermal pulses caused by the tidal forces of Jupiter and the other moons, Europa may be the best place in the solar system for finding life forms. Europa’s vast oceans are unequalled in the solar system, with one exception. 2 Using sophisticated instrumentation, lightning experts have learned that lightning travels at one-third the speed of light. A lightning bolts is five times hotter than the surface of the sun and have ten times more power than the output of a large power company. A single discharge can actually contain twenty or more successive strokes, occurring too fast for the eye to separate. Some seem to stretch for 500 miles when observed from outer space. It is possible that a lightning bolt, which seems very large, is really a series of bolts.
