Exoplanet may be 'made almost entirely of liquid water'

So far, most of the exoplanets we hear about are gas giants (like Jupiter) or massive, rocky "super-Earths." Neither of which are ideal for life. But a recent study suggests a planet circling the red dwarf "GJ 1214b" may be "made almost entirely of water." (New Scientist) The planet is 19-times the size of earth, but just 6.6 times the mass. "Such an object could be composed primarily of water." The discovery could be "the first clear example of a whole new population of exoplanets."
