We present new results on the massive young cluster NGC 2264 based on the analysis of data acquired from the Spitzer Space Telescope. The MIPS (Multiband Imaging Photometer for Spitzer) has enabled us to identify the most recent episodes of star formation in NGC 2264. In particular, the 24 micron data combined with submillimeter observations from Wolf-Chase (2003) indicate that the most recent star formation events have occurred primarily within dusty filaments of dense gas in the central regions of the complex. These observations provide interesting constrains for theoretical models of collapsing molecular clouds. Additional IRAC (Infrared Array Camera) and near-infrared JHK 2MASS data has enabled us to assemble spectral energy distributions which help elucidate the natures of the deeply embedded sources and confirm their extreme youth and status as protostellar objects.
