We used archival Spitzer infrared data to look for new young stellar objects (YSOs) in Cometary Globule 4 (CG4) in Puppis. CG4 is approximately 1300 parsecs away and one of about 30 cometary globules in the Gum Nebula, many of which are known to be forming stars. CG4 is dramatic in appearance, and that has brought it to the attention of both scientists and the public. Our team used archival Spitzer InfraRed Array Camera (IRAC) and Multiband Imaging Photometer for Spitzer (MIPS) data, combined with 2 Micron All Sky Survey (2MASS) data as well as optical data obtained by collaborators. We used infrared excess to investigate the properties of previously known YSOs in this region and identify additional new candidate YSOs in this region. This research was made possible through the NASA/IPAC Teacher Archive Research Project (NITARP) and was funded by NASA Astrophysics Data Program and Archive Outreach funds.
