NASA Exoplanet Science Institute Headlines
NExScI is the science operations and analysis center for NASA's Exoplanet Exploration Program. We provide tools and archives for the exoplanet community, administer the Sagan program of fellowships and workshops, and support the Large Binocular Telescope Interferometer and administration of the NASA Keck telescope time.

Sagan Fellow Jennifer Yee is the lead author on a recent ApJ
paper that uses Spitzer data along with ground-based data to find a remote gas planet about 13,000 light-years away, making it one of the most distant planets known. Read the full story here
The NASA-funded Large Binocular Telescope Interferometer, or LBTI, has completed its first study of dust in the "habitable zone" around a star
, opening a new door to finding planets like Earth. Dust is a natural byproduct of the planet-formation process, but too much of it can block our view of planets. The findings will help in the design of future space missions that have the goal of taking pictures of planets similar to Earth, called exo-Earths. NExScI provides data archiving and public distribution and project science functions for the LBTI for NASA.
A study by Bertrand Mennesson (JPL) and Rafael Millan-Gabet (NExScI) used Keck Interferometer data to tightly constrain the amount of exozodi dust likely to be encountered by future missions to image exo-Earths. The study also found a link between warm dust in the habitable zones of nearby Sun-like stars and more distant colder dust reservoirs analogous to the Kuiper belt. This link could be used to select stars around which to search for exo-Earths. Read more in the full stories from JPL

Future efforts to image exoplanets directly will concentrate on the nearest and brightest stars.
A catalog listing
the properties of such stars is now available for use in planning such missions (e.g. WFIRST-AFTA).
The Keck Observatory Archive (KOA)
announces the first public release of OSIRIS data. These data products contain complete sets of metadata for raw (level 0) images, including WCS information derived by KOA; and reduced (level 1) browse products derived from the public OSIRIS pipeline, automated by KOA. Finally, the search engine returns the optimum set of calibration files for reduction of raw science files. Altogether, we have released data from 1,003 nights, containing 32,000 science files (2.4 TB).
Data from all active instruments at the Keck Observatory are now in the public domain.
