A slice of sky in the constellation Bo繹tes, dubbed the "Extended Groth Strip", observed by NASA's Spitzer Space Telescope. The area covered is about 1 by 0.12 degrees. These patterns of light appear to be from the first stars and galaxies that formed in the universe. This image shows an initial infrared view of this patch, including foreground stars and a confusion of fainter galaxies, seen at a wavelength of 4.5 microns.
