Aliens may be living under the ice of exoplanets
Stephen Hawking is part of a project searching for intelligent life elsewhere in the universe, and the first place they may want to check is under ice.
Because scientists believe oceans hidden under high-pressure ice on alien planets could be 15 times deeper than our own and contain alien life.
Researchers say despite the thick layer of ice, if there enough heat is given off by the planets' interior, water can stay liquid under the icy surface.
The study was led by Dr. Lena Noack of the Royal Observatory of Belgium, whose team came to the conclusion that their water theory would hold true for planets up to 10 times the size of Earth.
The two exoplanets Kepler 62e and 62f could have oceans below their icy surface. 62e is estimated to be 1.6 times larger than Earth, and 62f may be 1.4 times larger.
Researchers are hoping to apply Noack's theory to Jupiter's moon Ganymede, as it appears to have a high water content relevant to its mass.
Or, if you prefer mythology to science, you could posit that any living beings on Ganymede may be hiding in the form of eagles.
