|Abstract =
Earth-size exoplanets and their slightly larger ‘super-Earth’ cousins are the most abundant planets orbiting close to Sun-like stars. These planets have diverse physical compositions, unusual atmospheres, and poorly understood origins. My talk will trace the discovery and early characterization of these small worlds through Doppler and transit surveys, and look forward to future discoveries with instruments such as SHREK.

|Abstract =
The most obvious method of studying extrasolar planets - directly imaging them alongside their parent star - is also the most difficult. Image contrasts exceeding a billion to one, at subarcsecond separations, are required to detect an analog of our solar system in reflected starlight. Following the charge of the Astro2010 decadal survey, the NASA Exoplanet Exploration Program (ExEP) is tasked with developing the technology and precursor science needed to realize the goals of directly imaging Earth analogs and characterizing their atmospheres for habitability and the presence of life. In this talk, I will review the history of efforts to image extrasolar planets; the methods that can be used, and technical challenges that must be met to image and characterize Earth analogs; the role of exoplanet imaging on the WFIRST mission; and how ExEP and the broader community are working to make a "New Worlds" space telescope into a ready option for our community in the 2020s.

Short bio sketch:

Karl Stapelfeldt is Chief Scientist of the NASA Exoplanet Exploration Program at NASA's Jet Propulsion Laboratory in Pasadena CA. He is an observational astronomer specializing in studying circumstellar disks, exoplanets, and planet formation at optical, infrared, and millimeter wavelengths. He has a B.S.E. in Engineering Physics from Princeton University and a Ph.D. in Astrophysics from Caltech. From 1993-1998 he was a member of the HST/WFPC2 instrument science team that restored Hubble's vision, followed by more than a decade in Project Science Office for the Spitzer Space Telescope. He has extensive experience in studies of future space missions for exoplanet direct imaging. From 2011-2016 he was Chief of the Exoplanets and Stellar Astrophysics Laboratory at NASA Goddard Space Flight Center.
