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.

Precise Measurement of an Alien World's Sizeimage

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.

First Earth-Size Planet in the 'Habitable Zone' of Another Starimage

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.

A Small Step Toward Discovering Habitable Earthsimage

Sagan Fellow Jared Males is lead author on a recent ApJ paper describing images of an exoplanet obtained with an Earth-based telescope using essentially the same type of imaging sensor found in digital cameras. The technology still has a long way to go, however the accomplishment takes astronomers a small step closer to imaging earth-like planets around other stars. Sagan Fellow Katie Morzinski is a co-author on the paper.

Meet the 2014 Sagan Postdoctoral Fellows!

2014 Sagan Summer Workshop

Presentations from this year's workshop on Imaging Planets and Disks are posted here; videos of the presentations will be posted in the coming weeks. Click here for more information.

Nearby Star List Available

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).

Call for 2014B NASA Keck Proposals

Second Kepler Science Conference, Nov. 4-8, 2013

Archived videos of talks, including the public lecture by Frank Drake, are available as links on the agenda page. Posters are also available as links on this page.

Have We Found Other Earths?

Read the statement of Dr. John M. Grunsfeld, NASA's Associate Administrator, Science Mission Directorate, before the Congressional Committee on Science, Space, and Technology Subcommittee on Space.

KOA Releases DEIMOS Data

The Keck Observatory Archive has released to the public 628 nights of data from the DEIMOS instrument. The released data include 27,409 science files and 56,514 calibration files. Another 665 nights of data will be released as their propriety period expires. Altogether, the DEIMOS total includes 38,308 science files and 71,881 calibration files (10.2 TB total). Access DEIMOS and other data here.
