SIRTF "Aliveness Test" Image

September 2003:
This engineering image is a quick look at the sky through the Infrared Array Camera (IRAC), one of three scientific instruments aboard SIRTF. The 5 arcmin x 5 arcmin image was taken in a low Galactic latitude region in the constellation Perseus. It results from 100 seconds of exposure time with the short-wavelength (3.6 micron) array.
