Space.com: NASA's Kepler Comes Roaring Back with 100 New Exoplanet Finds

KISSIMMEE, Fla. — NASA's Kepler spacecraft has bounced back nicely from the malfunction that ended its original exoplanet hunt more than two years ago.

Kepler has now discovered more than 100 confirmed alien planets during its second-chance K2 mission, researchers announced today (Jan. 5) here at the 227th Meeting of the American Astronomical Society (AAS).

The $600 million Kepler mission launched in March 2009, tasked with determining how commonly Earth-like planets occur throughout the Milky Way galaxy. Kepler has been incredibly successful, finding more than 1,000 alien worlds to date, more than half of all exoplanets ever discovered.

Will Kepler Find Habitable Moons?

From Science Daily:

ScienceDaily (Sep. 3, 2009) — Since the launch of the NASA Kepler Mission earlier this year, astronomers have been keenly awaiting the first detection of an Earth-like planet around another star. Now, in an echo of science fiction movies a team of scientists led by Dr David Kipping of University College London thinks that they may even find habitable ‘exomoons,’ too.

The new results will appear in a paper in Monthly Notices of the Royal Astronomical Society.

Planet-finder Shows Its Power: Kepler Orbiting Telescope Should Soon Find Alien Earths

ScienceDaily (Aug. 7, 2009) — The first results are in from the Kepler orbiting observatory, the world's most powerful planet-searching telescope, and according to MIT planetary scientist Sara Seager they show that the instrument should have no trouble detecting "alien Earths" -- planets that are about the size of our own.

From Science Daily:

ScienceDaily (Aug. 7, 2009) — The first results are in from the Kepler orbiting observatory, the world's most powerful planet-searching telescope, and according to MIT planetary scientist Sara Seager they show that the instrument should have no trouble detecting "alien Earths" -- planets that are about the size of our own.

After its launch on March 6, Kepler began taking test data for engineering purposes. It was this engineering data, before the official inauguration of science operations, that produced the observatory's first published results, appearing this week in the journal Science. Seager, the Ellen Swallow Richards Associate Professor of Planetary Science and Associate Professor of Physics, is part of the Kepler science team but was not personally involved in this initial paper. She appeared at a NASA press conference on Thursday, Aug. 6, to comment on the significance of the results.

Kepler Spacecraft Sees Its First Exoplanets

From New Scientist:

The planet-hunting Kepler space telescope has found its first extrasolar planets: three alien worlds that had been previously discovered with ground-based telescopes. The finds confirm that Kepler's instruments are sensitive enough to detect Earth-like planets around sun-like stars – but they might also be unexpectedly sensitive to charged particles in space that can zap circuitry.

Kepler launched on 6 March with a simple charge: Stare at a swatch of sky for three and a half years, and look for Earths. The telescope will hunt transiting exoplanets, planets that pass in front of their stars and dim their brightness at regular intervals.

Let The Planet Hunt Begin: Kepler Spacecraft Begins Search For Other Earth-like Worlds

From Science Daily:

ScienceDaily (May 15, 2009) — NASA's Kepler spacecraft has begun its search for other Earth-like worlds. The mission, which launched from Cape Canaveral, Fla., on March 6, will spend the next three-and-a-half years staring at more than 100,000 stars for telltale signs of planets. Kepler has the unique ability to find planets as small as Earth that orbit sun-like stars at distances where temperatures are right for possible lakes and oceans.

"Now the fun begins," said William Borucki, Kepler science principal investigator at NASA's Ames Research Center, Moffett Field, Calif. "We are all really excited to start sorting through the data and discovering the planets."

Kepler Blasts Off In Search Of Earth-Like Planets

From The L.A. Times:

The $590-million mission, jointly managed by JPL and NASA, will examine a star-rich stretch of sky for a planet where water could exist in liquid form.

NASA's Kepler spacecraft blasted off from Kennedy Space Center in Florida on Friday on a three-year mission to find Earth's twin, a Goldilocks planet where it's neither too hot nor too cold, but just right for life to take hold.

The Delta II rocket, carrying the widest-field telescope ever put in space, lifted off the launch pad at Cape Canaveral at 10:49 p.m. Eastern time.

The launch vehicle headed downrange, gathering speed as its three stages ignited, one after the other, passing over the Caribbean island of Antigua and tracking stations in Australia before climbing into orbit.

The Kepler Telescope: Taking A Census Of The Galaxy

At the Astrotech payload processing facility in Titusville, Florida, workers from Ball Aerospace check the star trackers on NASA's Kepler spacecraft before testing. NASA

From Time Magazine:

Think you could stare at a single spot without blinking for three and a half years? Then be glad you're not NASA's Kepler telescope, which is set to blast into space from Cape Canaveral this Friday night. Kepler's job may sound boring to you, but what the spacecraft accomplishes could be extraordinary: the discovery of the first Earth-like planets orbiting sun-like stars. Those kinds of places might well be brewing Earth-like forms of life.

Space Telescope To Boost Hunt For Alien Earths

From The New Scientist:

HOW common are alien Earths - small, rocky planets orbiting at the right distance to be not so hot that water boils and not so cold that it stays frozen? Till now clues have been hard to come by, because surveys have not been sensitive enough to find many such planets.

That should soon change thanks to the Kepler space telescope, which NASA is expecting to launch on 5 March. Its unique positioning in the solar system and unprecedented sensitivity mean that for the first time we will be able to see Earth-size planets in the "habitable zone" of their stars - the region where the temperature on the planet should be right for liquid water to exist at its surface.
