1. 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”

4. 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

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
