TL;DR: The James Webb Space Telescope (JWST) as discussed by the authors is a large (6.6 m), cold (<50 K), infrared-optimized space observatory that will be launched early in the next decade into orbit around the second Earth-Sun Lagrange point.

TL;DR: In this paper , the authors characterize the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period, with an emphasis on differences from pre-launch expectations.

TL;DR: The science objectives of the James Webb Space Telescope fall into four main themes: the End of the Dark Ages: First Light and Reionization, The Assembly of Galaxies, The Birth of Stars and Protoplanetary Systems, and Planetary Systems and the Origins of Life as discussed by the authors.

TL;DR: The James Webb Space Telescope (JWST) as mentioned in this paper is a large, segmented mirror with a five-layer sunshield that allows the telescope and instrument module to passively cool to cryogenic temperatures.
