poster of Kepler-186f
Where the Grass is Always Redder on the Other Side


Kepler-186f is the first Earth-size planet discovered in the potentially 'habitable zone' around another star, where liquid water could exist on the planet's surface. Its star is much cooler and redder than our Sun. If plant life does exist on a planet like Kepler-186f, its photosynthesis could have been influenced by the star's red-wavelength photons, making for a color palette that's very different than the greens on Earth. This discovery was made by Kepler, NASA's planet hunting telescope. Source: PlanetQuest, December 30, 2014. [Click image to get high resolution version.]
poster of super-Earth HD 40307g
Experience the Gravity
of a Super Earth


Super-Earths are larger than Earth, but smaller than giant planets, mostly between 1.25 and 2 times the diameter of Earth. Strangely, although the Kepler has found super-Earths to be some of the most common planets, there are no super-Earths in our own Solar System. HD 40307g is about 2.4 times Earth's radius. We aren't sure if it has a rocky surface or one that's buried beneath thick layers of gas and ice. At eight time the Earth's mass, its gravitational pull is much, much stronger.

poster of Kepler-16b
Relax on Kepler-16b - Where your shadow always has company


Like Luke Skywalker's planet "Tatooine" in Star Wars, Kepler-16b orbits a pair of stars. Depicted here as a terrestrial planet, Kepler-16b might also be a gas giant like Saturn. Prospects for life on this unusual world aren't good, as it has a temperature similar to that of dry ice. But the discovery indicates that the movie's iconic double-sunset is anything but science fiction. Source: PlanetQuest, December 15, 2014. [Click image to get high resolution version.]
Kepler Candidates/Transit of Venus Poster (2012 Feb 7; front updated 2013 Jan 7)

Using the prolific planet hunting Kepler spacecraft, astronomers have discovered 2,740 planet candidates orbiting other suns since the Kepler mission's search for Earth-like worlds began in 2009. To find them, Kepler monitors a rich star field to identify planetary transits by the slight dimming of starlight caused by a planet crossing the face of its parent star. In this remarkable illustration (above left) created by Jason Rowe of NASA's Kepler Science Team, all of Kepler's planet candidates are shown in transit with their parent stars ordered by size from top left to bottom right. Simulated stellar disks and the silhouettes of transiting planets are all shown at the same relative scale, with saturated star colors. Of course, some stars show more than one planet in transit, but you may have to examine the picture at high resolution to spot them all. For reference, the Sun is shown at the same scale, by itself below the top row on the right. In silhouette against the Sun's disk, both Jupiter and Earth are in transit.
