I will review an article by Strafella et al. who imaged the Vela-D molecular cloud at 3.6, 4.5, 5.8 and 8.0 microns using the Spitzer IRAC array. A total of approximately 170,000 point sources were detected in at least one of the wavebands at the 5sigma sensitivity level. The derived point source catalog was combined with additional observations at longer wavelengths to probe the young stellar object population and star formation history in the region.
