We have discovered a large number of symmetric shells around luminous central sources at 24 μm with MIPS on board the Spitzer Space Telescope. Follow-up investigation utilizing the data from the GLIMPSE project, which samples the 3.5-8.0 μm wavelength range, as well as 2MASS and the Digitized Sky Survey shows that about 65% of these shells are only detected at 24 μm. We also find that most of the central sources of the circumstellar shells are still detected in the 2MASS J band, but largely invisible in the optical. A SIMBAD search within 1' of the accurate central source coordinates reveals that most of these sources (99%) have not been previously studied. We suspect that a fraction of the central stars represent a population of highly obscured massive stars. We will present early results from dedicated follow-up observations aimed at characterizing this population.
