JWST: Planets to Cosmology
Mario Livio Space Telescope Science Institute
2
Hardware progressing: Mirror in final stages of testing
3
Hardware progressing: Sunshield full-scale membrane
The James Webb Space Telescope Hardware progressing: Sunshield full-scale membrane The JWST sunshield - full scale membrane - Each successive layer of the sunshield is cooler than the one below it, heat radiates away from between layers. - Jason has Kapton in his office if needed. Log scale: 2.0” x 2.0” Linear scale: 2.0” x 2.0”

JWST will see the very first galaxies
Hubble UDF Could also stress: 1.) Success of archives 2.) Prize postdoctoral fellowships – Hubble, Spitzer, Chandra, ?Webb? springboard for launching career in astronomy. Simulated JWST
5
Razor sharp vision of early universe
Spitzer, 90,000s per band (GOODS collaboration) 1’x1’ region in the UDF – 3.5 to 5.8 μm JWST, 1000s per band (simulated) Implications for: Pop III star clusters?, reionization, cosmic star formation history, structure formation, galaxy evolution
6
Extrasolar planets: habitable zone
The James Webb Space Telescope Extrasolar planets: habitable zone JWST will see planets around other stars Maggie Masetti, Goddard - Picture on bottom is their fridge.
7
Spectrum of a known life-bearing planet
8
JWST: spectroscopy and photometry of transiting exoplanets
Temperature-pressure profiles, molecular species, moons
9
Discovery of: Water Worlds, necessary ingredients for life
