Animated Zoom-In of How Kepler is Revolutionizing the Understanding of the Relationship between Planet's Masses & Radii: The animation shows the mass-radius diagram based on measurements of 127 exoplanets. The video begins by shows planets with masses similar to Jupiter and slowly zooms towards small masses and radii to display a comparison of the physical properties of the Kepler-138 planets relative to Earth, Venus, Mars and Mercury.

Discussion of Kepler-138 Results: Penn Stat's Dr. Daniel Jontof-Hutter joins SETI Institute research scientists Jawson Rowe, Nathalie Cabrol, and Jill Tarter for a discussion about Kepler-138 system and the future of planet hunting.



Planets in Systems from NASA's Kepler Mission: The image above depicts the multiple planet systems discovered by NASA's Kepler mission. 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). For reference, the eight planets of the solar system are shown in blue.

Kepler's Planetary Systems in Motion: This animation shows the orbital position of the planets in systems with multiple transiting planets discovered by NASA's Kepler mission. All the colored planets have been verified. More vivid colors indicate planets that have been confirmed by their gravitational interactions. Several of these systems contain additional planet candidates (shown in grey) that have not yet been verified. (Credit: Dan Fabrycky, UC Santa Cruz)



Confirming Planets using Transit Timing Variations This animation shows the how planet transit times differ depending on whether the system contains one planet or multiple planets. (Credit: NASA Ames Research Center/Kepler Mission)


Related to ALMA Observations of Dusty Disks around Young Stars

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. Note that ALMA has so far only observed a part of the ring. The underlying blue picture shows an earlier picture obtained by the NASA/ESA Hubble Space Telescope. Credit: ALMA (ESO/NAOJ/NRAO).

Left: 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. (Credit: ESA w/ adaptations by David Sing).
