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.

While analyzing spectrographic data from the W.M. Keck Observatory in Hawaii, NASA Keck PI Kim Vy-Tran spotted a strong detection of hot hydrogen gas that appeared to arise from a massive, bright elliptical galaxy. This fingerprint of hydrogen led to the discovery of a record-breaking cosmic magnifying glass. Read the full story
Sagan Fellow Sarah Ballard is the lead author on a ApJ paper
describing the most precise measurement ever of the radius of a planet outside our solar system. The findings confirm Kepler-93b as a "super-Earth", about one-and-a-half times the size of our planet. Although super-Earths are common in the galaxy, none exist in our solar system. Exoplanets like Kepler-93b are therefore our only laboratories to study this major class of planet.
The NASA Exoplanet Archive
has 10 new planets, including Kepler-186 f, an Earth-radius planet located within the habitable zone of the host star, as featured in this press release
and the published paper
for applications for the 2015 Sagan Postdoctoral Fellowships is now closed. Click here

The 2015 Sagan Summer Workshop on Exoplanetary System Demographics: Theory and Observation
will be held July 27-31, 2015 at Caltech. Click here
for more information.
Videos of the presentations from this year's workshop on Imaging Planets and Disks
are now posted, view them here
and on the Sagan Summer Workshop YouTube channel

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).
Archived videos of talks, including the public lecture by Frank Drake
, are available as links on the agenda page
The Keck Observatory Archive (KOA) has released to the public data from the Echellette Spectrograph and Imager (ESI) instrument. 780 nights of data have been released, consisting of 21,988 science files and 27,935 calibration files.
KOA has also released to PIs, 973 nights of data from the the now decommissioned Near Infrared Camera (NIRC), comprising 263,238 files with a data volume of 276 GB. These data will start to become public in July 2015. Access ESI, NIRC, and other data here
