Hubble Space Telescope (hst): Hubble Space Telescope (hst)

Hubble Space Telescope (HST):

• Hubble Space Telescope (HST):

• 2.7 x diameter, 2.7 x longer wavelength

• HST NICMOS:

• 189 x FoV,
• 38 x better sensitivity at K band, 8 x at H band

• Spitzer:

• 8 x Spitzer diameter
• Diffraction limited at 2 microns vs. 6 microns
• 8 to 24 x better angular resolution
• 10 x lower dark current supports R ~ 1000 at high redshift

• Ground:

• JWST and GSMT are complementary where capabilities overlap:
• HST: Keck diameter ratio ~ JWST:GSMT
• Background ~1,000,000 x larger on ground at 5 microns
