Through Exoplanet and James Webb Space Telescope

History

In 1995, astronomers using ground-based observatories discovered 51 Pegasi b, the first exoplanet orbiting a Sun-like star. NASA launched the Kepler space telescope in 2009 to search for Earth-size exoplanets. By 2015, they had confirmed more than a thousand exoplanets, while several thousand additional candidates awaited confirmation.

To help coordinate efforts to sift through and understand the data, NASA needed a way for researchers to collaborate across disciplines. The success of the Virtual Planetary Laboratory research network at the University of Washington led Mary A. Voytek, director of the NASA Astrobiology Program, to model its structure and create the Nexus for Exoplanet System Science (NExSS) initiative. Leaders from three NASA research centers will run the program: Natalie Batalha of NASA's Ames Research Center, Dawn Gelino of the NASA Exoplanet Science Institute, and Anthony Del Genio of NASA's Goddard Institute for Space Studies.
