Here we report the sizes and masses of three planets orbiting Kepler-138, a star much fainter and cooler than the Sun. We determine that the mass of the Mars-sized inner planet, Kepler-138 b, is $0.066^{+0.059}_{-0.037}$ Earth masses. The middle and outer planets are both slightly larger than Earth…

The diagram compares the planets of our inner solar system to Kepler-186, a five-planet star system about 500 light-years from Earth in the constellation Cygnus. The five planets of Kepler-186 orbit an M dwarf, a star that is is half the size and mass of the sun. The Kepler-186 system is home to Kepler-186f, the first validated Earth-size planet orbiting a distant star in the habitable zone – a range of distance from a star where liquid water might pool on the planet's surface.

Zooming in on Fomalhaut This video sequence starts with a wide-field view of the sky around the star Fomalhaut in the constellation of Piscis Austrinus (The Southern Fish). Fomalhaut is the brightest star in the constellation and one of the brightest stars known to have an orbiting planet. It lies about 25 light-years from the Earth and is surrounded by a huge disc of dust. The final view of this video shows a new ALMA image of the disc (orange) and the new results from ALMA have given astronomers a major breakthrough in understanding a nearby planetary system and provided valuable clues about how such systems form and evolve.

Planets in Systems from NASA’s Kepler Mission The image above depicts multiple planet systems discovered by NASA’s Kepler mission and confirmed by transit timing variations (as of January 2012). Out of hundreds of candidate planetary systems, scientists had previously verified six systems with multiple transiting planets (denoted here in red). Now, Kepler observations have verified planets (shown here in green) in 11 new planetary systems. Many of these systems contain additional planet candidates that are yet to be verified (shown here in dark purple).

When an exoplanet transits across the face of its host star atoms and gases in its atmosphere absorb some of the starlight at specific wavelengths. These absorption wavelengths form a unique fingerprint, allowing researchers to identify the presence of Potassium.
