Kepler telescope discovers first five exoplanets
NASA’s Kepler space telescope, designed to find Earth-size planets in
the habitable zone of sun-like stars, has discovered its first five new
exoplanets, or planets beyond our solar system.
Kepler’s high sensitivity to both small and large planets enabled the
discovery of the exoplanets, named Kepler 4b, 5b, 6b, 7b and 8b. The
discoveries were announced Monday by the members of the Kepler science
team during a news briefing at the American Astronomical Society meeting
in Washington.
“These observations contribute to our understanding of how planetary
systems form and evolve from the gas and dust disks that give rise to
both the stars and their planets,” said William Borucki of NASA’s Ames
Research Center in Moffett Field, California. Borucki is the mission’s
science principal investigator. “The discoveries also show that our
science instrument is working well. Indications are that Kepler will
meet all its science goals.”
Known as “hot Jupiters” because of their high masses and extreme
temperatures, the new exoplanets range in size from similar to Neptune
to larger than Jupiter.
