According to Space.com, NASA has unveiled the existence oftwo planets larger than our own Earth that are made up entirely of large oceans. However, the two planets, Kepler-62e and Kepler-62f, are 1,200 light years away, which makes them impossible to study or analyze with the instruments and technology currently present on our world.
Still, it’s pretty cool that there are at least two other planets out there that have the possibility to have some sort of organisms living on them. These two are being dubbed “Water World” planets in reference to the movie and book that portrayed the Earth as being covered completely by water (of course, they did find land at the end). Sometimes it is pretty cool how science fiction and fantasy act as precursors to actual discoveries.
The discovery of these two planets is important, but their distance to Earth means that they will just be the subject of wonder for years (probably decades and centuries to come). After all, we still do not know everything our oceans are hiding, let alone anything living on two alien planets.
