The Universe


Galactic survey
At the beginning of the mission, Spitzer will hold a series of imaging surveys in the mid and far infrared. Census Deep and a small region of space, including one centered on the Hubble Deep Field (English) , study the young and distant universe with redshifts of about 5, which corresponds to about 12 billion years.
