JWST: Launch, Commissioning, and Cycle 1 Science

Science Meeting
August 20 - 22, 2018
Vienna, Austria/Room F2

The James Webb Space Telescope (JWST) is expected to revolutionize our understanding of the near- to mid-infrared sky by enabling observations with an unprecedented combination of superb angular resolution and sensitivity. Since JWST is a general-purpose observatory, its scientific success is dependent on the broader scientific community to make new discoveries. The 2018 IAU General Assembly will provide an important international platform to inform the broader community about plans for commissioning and Cycle 1 science and what to expect in the near-future for JWST.

This focus meeting will highlight the science that will be enabled by JWST early in its life cycle and touch on commissioning, Early Release Science (ERS), Guaranteed Time Observer (GTO), and General Observer (GO) programs slated for cycle 1. Members of the design team for the four JWST science instruments (MIRI, NIRCam, NIRSpec, and NIRISS) will discuss the science potential of their instruments. Talks and discussion sessions aimed at the broad science topics enabled by JWST, from our solar system to the edge of the universe, will be drawn from contributions from the entire astronomical community. Given the cross-disciplinary and international nature of JWST’s mission, this focus meeting will be the ideal opportunity to discuss the science that will be enabled with JWST in the near-term.

Key topics include:

  • The scientific prospects of JWST from within our solar system to the edge of the universe.
  • Solar system science with JWST: From the surfaces of asteroids to the atmospheres of giant planets.
  • Exoplanet science with JWST: From the birth of planets to the search for life.
  • Galactic science with JWST: From the birth and evolution of stars and everything in between.
  • Extragalactic science with JWST: From galaxies near to far and first light.
  • JWST for all astronomers: Cycle 1 science and future opportunities.
  • JWST’s four remarkable instruments and their unique science capabilities.
  • Ensuring the science yield of JWST through ground-testing, commissioning, and calibration activities.
