The 'Habitable Edge' of Exomoons

Astronomers have their fingers crossed that within the haul of data collected by NASA's Kepler mission, which has already detected nearly three thousand possible exoplanets, hide the signatures of the very first exomoons.

The discovery of alien moons will open up an exciting new frontier in the continuing hunt for habitable worlds outside the Solar System. With the confirmation of exomoons likely right around the corner, researchers have begun addressing the unique and un-Earthly factors that might affect their habitability.
