NASA’s Kepler space telescope recently identified a system of five exoplanets orbiting a red dwarf star about 1,200 light years from Earth. Two of the exoplanets (dubbed Kepler-62e and 62f) lie within the habitable zone of the system and are thought to be completely covered by water. Kepler-62e is particularly interesting to researchers, as it is only 1.6 times the size of Earth and appears to have a climate that would be warm and humid all the way to its polar regions. Although it is difficult to imagine civilizations arising on such water worlds, scientists believe that conditions are possibly conducive to the evolution of fairly advanced organisms – assuming, of course, that life got a start at all.
