As I noted here, Kepler-22b was discovered earlier this month. Kepler-22c and Kepler-22d have also been found as part of the mission.
The announcement came today that too more planets have been discovered by the Kepler spacecraft. These two planets have been named, appropriately enough, Kepler-22e and Kepler-22f.
Here is a snippet from The New York Times’ article:
Astronomers said the discovery showed that Kepler could indeed find planets as small as our own and was an encouraging sign that planet hunters would someday succeed in the goal of finding Earth-like abodes in the heavens.
Since the first Jupiter-size exoplanets, as they are known, were discovered nearly 15 years ago, astronomers have been chipping away at the sky, finding smaller and smaller planets.
“We are finally there,” said David Charbonneau, an astronomer at the Harvard-Smithsonian Center for Astrophysics, who was a member of the team that made the observations, led by his colleague Francois Fressin. The team reported its results in an online news conference Tuesday and in a paper being published in the journal Nature.
