The data also includes details of more than 1,000 additional exoplanet candidates.

The mission is expected to continue until at least 2016, in which time many more exoplanet candidates are expected to be found.

Is used to verify exoplanet candidates found by Kepler.

In June 2010, some 43 days after Kepler came online, its operating scientists submitted a list of over 700 exoplanet candidates for review.

Now, researchers working with data from the Kepler space-based observatory have identified two more promising exoplanet candidates orbiting binary stars, known as Kepler-34b and Kepler-35b.

Kepler 22-b was one of 54 exoplanet candidates in habitable zones reported by the Kepler team in February, and is just the first to be formally confirmed using other telescopes.

In addition to discovering hundreds of exoplanet candidates, the Kepler spacecraft has also reported 26 exoplanets in 11 systems which have not yet been added to the Extrasolar Planet Database.
