More planets than stars: Kepler's legacy

The Kepler mission enabled the discovery of thousands of exoplanets, revealing a deep truth about our place in the cosmos: There are more planets than stars in the Milky Way galaxy. The road to this fundamental change in ...

Do red dwarfs or sunlike stars have more Earth-sized worlds?

Earth is our only example of a habitable planet, so it makes sense to search for Earth-size worlds when we're hunting for potentially-habitable exoplanets. When astronomers found seven of them orbiting a red dwarf star in ...

Astronomers detect a second planet orbiting two stars

Planets orbiting binary stars are in a tough situation: They have to contend with the gravitational pull of two separate stars. Planetary formation around a single star like our sun is relatively straightforward compared ...

The strange orbits of 'Tatooine' planetary disks

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary star systems share ...

Kepler Mission

The Kepler Mission uses a NASA space telescope designed to discover Earth-like planets orbiting other stars. Orbiting the sun for at least 3.5 years, Kepler will use a photometer developed by NASA to continuously monitor the brightness of over 100,000 stars in a fixed field of view. The data collected from these observations will be analyzed to detect periodic fluctuations that indicate the presence of transiting exoplanets. The mission is named in honor of German astronomer Johannes Kepler.

Kepler is a mission under NASA's Discovery Program of low-cost, focused science missions. NASA's Ames Research Center is the home organization of the science principal investigator and is responsible for the ground system development, mission operations and science data analysis. Kepler mission development is managed by NASA's Jet Propulsion Laboratory. Ball Aerospace & Technologies Corp. is responsible for developing the Kepler flight system.

The Kepler Spacecraft was launched on March 6, 2009 at 22:49:57 UTC-5.
