Discovery of Kepler-16b
NASA’s Kepler mission has turned fiction into fact. A world with a double sunset that was first imagined in 'Star Wars' over 30 years ago in a galaxy far, far away has become scientific reality. Credit: NASA / Ames Research Center

First Multi-Planet System Discovered by Kepler
NASA's Kepler Mission has discovered the first confirmed planetary system with more than one planet transiting the same star. The announcement of the discovery of the two planets, Kepler 9b and 9c, is based on seven months of observations.

Getting to Know the Goldilocks Planet
NASA's Kepler spacecraft is discovering a veritable avalanche of alien worlds. As the numbers mount, it seems to be just a matter of time before Kepler finds what astronomers are really looking for: an Earth-like planet orbiting its star in the 'Goldilocks zone'.

Kepler Discovers Earth-size Planet Candidates
NASA's Kepler mission has discovered its first Earth-size planet candidates and its first candidates in the habitable zone, a region where liquid water could exist on a planet's surface. Five of the potential planets are near Earth-size and orbit in the habitable zone of smaller, cooler stars than our sun.

Kepler- One Year Anniversary
NASA's Kepler spacecraft has successfully completed the first year of its mission to search for Earth-like planets in our galaxy.

Kepler- The Search for Earth-Size Planets Begins
Since its launch in March, 2009, the Kepler Mission has announced the discovery of 9 confirmed exoplanets (or planets outside our solar system). This video explores how the team works to combine photometry from the spacecraft, data from ground-based observatories and precise asteroseismic analysis to determine if Earths are common or rare in our Galaxy.

Kepler-20 System Overview
NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system. The planets, Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet's surface, but they are the smallest exoplanets ever confirmed around a star like our sun

NASA's Kepler Mission Discovers Multiple Planets Orbiting Twin Suns
NASA's Kepler mission has discovered the first transiting circumbinary system -- multiple planets orbiting two suns -- 4,900 light-years from Earth, in the constellation Cygnus, proving that more than one planets can form and survive in orbit around a binary star. The inner planet, Kepler-47b, orbits the pair of stars in less than 50 days. It is thought to be a sweltering world, where the destruction of methane in its super-heated atmosphere might lead to a thick haze that could blanket the planet. At three times the radius of Earth, Kepler-47b is the smallest known transiting circumbinary planet. The outer planet, Kepler-47c, orbits its host pair every 303 days, placing it in the so-called 'habitable zone,' the region in a planetary system where liquid water might exist on the surface of a planet. While not a world hospitable for life, Kepler-47c is thought to be a gaseous giant, slightly larger than Neptune, where an atmosphere of thick bright water clouds might exist. For more ...

Study of Hubble Data Revives 'Dead' Exoplanet
In 2008, Hubble astronomers announced the detection of a giant planet around the bright star Fomalhaut. Recent studies have questioned this conclusion. Now, a reanalysis of Hubble data has revived the 'deceased' exoplanet as a dust-shrouded world with less than twice the mass of Jupiter.

The Hubble Legacy- Exoplanets
Three astronomers in NASA Goddard's Exoplanets and Stellar Astrophysics Laboratory discuss how Hubble's coronagraph and resulting images have helped scientists find planets orbiting distant stars.

Webb Telescope- Planetary Evolution
Stars and planets form in the dark, inside vast, cold clouds of gas and dust. The James Webb Space Telescope's large mirror and infrared sensitivity will let astronomers peer inside dusty knots where the youngest stars and planets are forming
