Kepler Confirms First Planet in Habitable Zone of Sun-like Star

From NASA Science:

The newly confirmed planet, Kepler-22b, is about 2.4 times the radius of Earth. Scientists don’t yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets.

This goes to show how we have so much more to learn about our universe. Astronomy is just one of the very exciting fields today.
