JWST:Planets to Cosmology

Mario LivioSpace Telescope Science Institute


Hardware progressing:Mirror in final stages of testing


The James Webb Space Telescope

Hardware progressing: Sunshield full-scale membrane

The JWST sunshield - full scale membrane

Log scale: 2.0” x 2.0”

Linear scale: 2.0” x 2.0”


JWST will see the very first galaxies

Hubble UDF

Simulated JWST


Razor sharp vision of early universe

1’x1’ region in the UDF – 3.5 to 5.8 μm

Implications for: Pop III star clusters?, reionization, cosmic star formation history, structure formation, galaxy evolution

Spitzer, 90,000s per band(GOODS collaboration)

JWST, 1000s per band(simulated)


The James Webb Space Telescope

Extrasolar planets:habitable zone

JWST will see planets around other stars


Spectrum of a knownlife-bearing planet


JWST: spectroscopy and photometry of transiting exoplanets

Temperature-pressure profiles, molecular species, moons


Discovery of: Water Worlds, necessary ingredients for life
