NASA will host a news teleconference at 2 p.m. EDT Thursday, April 17, to announce a new discovery made by its planet-hunting mission, the Kepler Space Telescope.
The journal Science has embargoed the findings until the time of the news conference.
The briefing participants are:
-- Douglas Hudgins, exoplanet exploration program scientist, NASA's Astrophysics Division in Washington
-- Elisa Quintana, research scientist, SETI Institute at NASA's Ames Research Center in Moffett Field, Calif.
-- Tom Barclay, research scientist, Bay Area Environmental Research Institute at Ames
-- Victoria Meadows, professor of astronomy at the University of Washington, Seattle, and principal investigator for the Virtual Planetary Laboratory, a team in the NASA Astrobiology Institute at Ames
Launched in March 2009, Kepler is the first NASA mission capable of finding Earth-size planets in or near the habitable zone -- the range of distance from a star in which the surface temperature of an orbiting planet might sustain liquid water. The telescope has since detected planets and planet candidates spanning a wide range of sizes and orbital distances, including those in the habitable zone. These findings have led to a better understanding of our place in the galaxy.
For dial-in information, media should e-mail their name, affiliation and telephone number to J.D. Harrington at email@example.com no later than noon Thursday.
