The Far-Infrared Deep Extragalactic Legacy survey is a Spitzer Legacy science program which has obtained the most extensive deep field imaging with the Spitzer/MIPS instrument. This is the first program to obtain true far-infrared data (at 70 and 160 microns) deep enough to detect hundreds of relatively ordinary (not only hyperluminous) dusty starburst galaxies and active galactic nuclei at 1 < z < 2.5. The FIDEL 70 micron data measure rest-frame thermal emission from warm dust that is believed to be a very direct tracer of star formation, longward of the complex mid-infrared region that is dominated by strong spectral features (e.g. PAH emission, silicate absorption) with complex underlying physics. At the same time, extremely deep (near GOODS-depth) 24 micron imaging detects mid-infrared emission from much larger numbers of galaxies at fainter luminosities. The survey covers approximately 0.6 square degrees in three fields: the Extended Groth Strip (as part of the AEGIS consortium), the Extended Chandra Deep Field South, and GOODS-North. The Spitzer observations have recently been completed, and here we present the FIDEL data and show science results from early analysis.
