PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

This artist's concept shows a Super Venus planet on the left, and a Super Earth on the right. Researchers use a concept known as the habitable zone to distinguish between these two types of planets, which exist beyond our solar system.

Super Venuses and Super Earths are similar to Venus and Earth, respectively, but larger in mass. Similar to our solar system's worlds, a Super Venus would most likely be a dry, toxic wasteland while a Super Earth might host oceans.

The habitable zone is the region around a star where liquid water -- an essential ingredient for life as we know it -- can pool on the surface. Earth lies within the habitable zone around our star. A recent study looked at the planet Kepler-69c, discovered by NASA's Kepler mission and originally thought to lie in its star's habitable zone. The planet is 1.7 times the size of Earth and lies 2,700 light-years away. The analysis showed that this planet lies just outside the inner edge of the zone, making it more of a Super Venus than a Super Earth. That means the planet is not a tropical paradise, but more likely scorching hot, with volcanic eruptions.

The search for planets as small as Earth, situated in the habitable zones of stars like our sun, is ongoing.

NASA Ames manages Kepler's ground system development, mission operations and science data analysis. NASA's Jet Propulsion Laboratory in Pasadena, Calif., managed Kepler mission development. Ball Aerospace & Technologies Corp. in Boulder, Colo., developed the Kepler flight system and supports mission operations with JPL at the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder. The Space Telescope Science Institute in Baltimore archives, hosts and distributes the Kepler science data. Kepler is NASA's 10th Discovery Mission and is funded by NASA's Science Mission Directorate at the agency's headquarters in Washington.
