NASA’s James Webb Space Telescope — the largest and most powerful space science observatory ever built — is designed to give astronomers unprecedented insight into the mysteries of the cosmos. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency. It is scheduled to launch this fall.

Cornell University scientists are playing key roles in the mission. The following are available for interviews:

Nikole Lewis is the principal investigator for one of the teams investigating the TRAPPIST-1 system — rocky, Earth-size worlds that orbit an ultra-cool star 41 light-years from Earth. She is an assistant professor of astronomy and the deputy director of the Carl Sagan Institute.

Ray Jayawardhana and Lisa Kaltenegger are part of a team that will dedicate 200 hours of time on the Webb telescope to characterize exoplanets. Jayawardhana is the Dean of Arts and Sciences and a professor of astronomy. Kaltenegger is an associate professor of astronomy and director of the Carl Sagan Institute.

Jonathan Lunine is the interdisciplinary scientist for astrobiology on the Webb mission. His hours on the telescope will be mostly used to look at gas giant planets that are very close to their stars. Lunine worked for decades on the Saturn Cassini program. He is chair of the department of astronomy.

James Lloyd helped develop an instrument for the telescope that will be used to image planetary systems and their environments. His research interests cover broadly extrasolar planets and the development of astronomical instrumentation. Lloyd is a professor of astronomy.
