“We now know the rate of occurrence of habitable planets around the most common stars in our galaxy,” said co-author David Charbonneau (CfA). “That rate implies that it will be significantly easier to search for life beyond the solar system than we previously thought.”

A hypothetical planet is depicted here moving through the habitable zone and then further out into a long, cold winter.

Red Dwarf Planet

The artist's conception shows a hypothetical planet with two moons orbiting in the habitable zone of a red dwarf star.

This is an artist's concept of a hypothetical 10-million-year-old star system. The bright blur at the center is a star much like our sun. The other orb in the image is a gas-giant planet like Jupiter.
