GOODS unites extremely deep observations from NASA's Great Observatories,
ESA's Herschel and
and from the most powerful ground-based facilities,
to survey the distant universe to the faintest flux limits
across the electromagnetic spectrum.
GOODS data track the formation and evolution of galaxies across cosmic time
and map the history of universal expansion using high redshift supernovae.
The survey covers a total of roughly 320 square arcminutes in two fields centered on the
Hubble Deep Field North and the
Chandra Deep Field South.
It incorporates a
Spitzer Space Telescope Legacy Program
to carry out the deepest observations with that facility at 3.6 to 24 microns, a
Hubble Space Telescope Treasury Program
for deep high-resolution optical imaging, and a
Herschel Space Observatory open time Key Program
with the deepest far-infrared observations at 100 to 500 microns.
The space-based observations are complemented by ground-based imaging and spectroscopy,
including extensive commitments of
and NOAO observing time.
GOODS public data products are extensively used by the astronomical community at large.
