Scientific Colloquium
March 12, 2004

The Spitzer Space Telescope, NASA's Great Observatory
for infrared exploration of the Universe, was launched
in August, 2003.  Spitzer is a cryogenically/radiatively
cooled observatory which offers scientific opportunities
to the entire scientific community.  The observatory is working flawlessly
on orbit, returning images and spectra of unprecedented
depth and quality.  This talk will highlight the early
scientific return from Spitzer - including results obtained
by the IRAC camera built at GSFC - and point out the likely
directions of further studies and discoveries.
