This artist’s concept portrays the seven rocky exoplanets within the TRAPPIST-1 system, located 40 light-years from Earth. The Telescope Scientist Team will collaborate with other JWST teams to observe these worlds with Webb in an effort to detect the first atmosphere of an Earth-sized planet beyond our solar system.

The JWST Telescope Scientist Team, led by AURA President Matt Mountain, has provided scientific support of the Webb Observatory development since 2002. The team has access to 210 hours of Guaranteed Time Observer time, which will be used to address three key subject areas through different observational techniques:

  • Characterization of the exoplanet atmospheres of a hot Jupiter, a warm Neptune, and a super Earth, through transit and eclipse spectroscopy
  • Characterization of exoplanet systems, debris disks, and brown dwarfs, through coronagraphic imaging
  • Characterization of the stellar proper motion kinematics of Local Group dwarf galaxies and the Galactic Center through astrometric imaging

The joint goal of these studies is to scientifically demonstrate the telescope performance after JWST launch. The results will provide new insights into exoplanet atmospheres, systems, and formation, as well as into galaxy formation, the characteristics of dark matter, and the black hole in the Galactic Center.
