The IRAC photometry reveals ongoing star formation in the M8 complex, with 64 class 0/I and 168 class II sources identified in several locations in the vicinity of submm gas cores/clumps. Description: The Spitzer Space Telescope IRAC observations of M8 were obtained by the Spitzer Science Center (SSC) on 2005 September 16. File Summary:
