Kepler space telescope finds its first extrasolar planets…
Mission uncovers one Neptune-like and four Jupiter-like bodies.
—
NASA’s planet-hunting Kepler mission is off to a precocious start. The first six weeks of observations recorded by the spacefaring telescope, combined with follow-up studies from the ground, have revealed five previously unknown extrasolar planets—one body roughly the size of Neptune and four low-density versions of Jupiter. All reside within roasting distance of their parent stars.
The findings appear to reinforce hints from ground-based observations that stars have relatively few close-in planets with a mass between that of Saturn and Neptune, says Kepler scientist Dimitar Sasselov of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass.
Lead mission scientist William Borucki of NASA’s Ames Research Center in Mountain View, Calif., and his colleagues announced the findings on January 4 at the winter meeting of the American Astronomical Society in Washington, D.C. The team also describes its results online January 7 in Science.
Astronomers say that the early results from the mission, which detects planets by recording tiny decreases in starlight whenever one of the orbs transits, or passes across the face of its parent star, also bode well for achieving Kepler’s main goal: finding Earthlike planets in or near the habitable zone of sunlike stars.

Crazy, crazy stuff. Didn’t some guy say the we were just a speck of dust compared to the universe? ; )
