Previously, the only two confirmed exoplanets in the habitable zone of their star (where liquid water could exist) were orbiting the same red dwarf star.

NASA's orbiting Kepler telescope has found an exoplanet, called Kepler-10b, located over 500 light years from Earth.

The CoRoT (Convection, Rotation and Transits) telescope which orbits Earth under the control of the French Space Agency (CNES) has found six new exoplanets.

NASA’s orbiting Kepler telescope launched last March.
