Distant exoplanets could harbour life in 'terminator zones': Study

"Terminator zones" on distant exoplanets, or zones where the "day" side of the planet meets the "night" side, could potentially harbour extraterrestrial life, according to a new study. Astronomers from University of California, Irvine (UCI), US, describe "terminator" as the dividing line between the day and night sides of the planet, which have one side that always faces its star and one side that is always dark.
