Exoplanets Containing Water May Be More Common Than Believed

Some exoplanets with masses two to four times the size of Earth can be explained by large amounts of water- and they may be more common than previously thought, say researchers. The 1992 discovery of exoplanets orbiting other stars has sparked interest in ...
