The quest for extraterrestrial life hinges on the results of planetary exploration, but some scientists believe humans should be looking at moons instead.
A team of researchers from Australia and California say they have identified more than a hundred planets in the Milky Way that may have moons that could be prime targets in the search for alien life.
Their findings will also be used to help develop a powerful new telescope that will be able to look for biosignatures, or the telltale signs of life as we know it, in the moons of other planets.
In a new paper published in the Astrophysical Journal, astrophysicists from the University of Southern Queensland and the University of California, Riverside say they have found 121 giant planets outside the solar system that are possibly surrounded by moons that could serve as hosts for life.
