A team led by NExScI scientist John Johnson used data from NASA's Kepler mission to discover the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star and are 0.78, 0.73 and 0.57 times the radius of Earth. Click here for the press release.
Habitable Zone Gallery
This Habitable Zone Gallery provides information for exoplanetary systems with known planetary orbital parameters including a planetary properties table, a gallery that plots the orbits and the location of the HZ, and movie animations for the planetary orbits.

The Keck Observatory Archive (KOA) has released raw and calibrated images from the Near Infrared Camera 2 (NIRC2). This is the first imaging instrument archived in KOA, and the third instrument altogether. As of May 7, 1,240 nights of NIRC2 data have been archived, and 932 nights are public. These data include all four observing modes. New data will be added whenever NIRC2 is scheduled on the telescope. The NIRC2 data may be accessed through the KOA search page.Proposal Call for Exozodi Key Science Team
NASA solicits proposals to become members of the Large Binocular Telescope Interferometer (LBTI) Exozodi Key Science Team (LBTI-ST). This proposal call is now closed. Click here for more information.Call for NASA Keck Observing Proposals
The call for 2012B proposals for NASA Keck time is now closed. Proposals for the 2013A observing semester will be due on Sept. 13, 2012. Click here for more information.Billions of Planets
NExScI scientist Dr. Stephen Kane co-authored a paper (Nature, January 2012) announcing the discovery that the Milky Way galaxy contains at least 100 billion planets from statistical studies of microlensing events. Click here for the NASA press release.
