Astronomers, with the help of NASA's Kepler Space Telescope, have discovered a planet that closely resembles Earth's size and orbits a red dwarf star in the habitable zone about 493 light-years away.
Less than a month after scientists discovered liquid methane waves on the Saturn moon of Titan, researchers, using NASA's Cassini spacecraft, have now discovered a body of liquid water under the icy surface of Saturn's other moon Enceladus.
The Saturn moon Titan is one of the most peculiar places in the solar system as it is the only planetoid besides earth to be carrying stable bodies of liquid on its surface - although that liquid is comprised of methane and ethane.
