Abstract: High spatial resolution radio continuum and mid-infrared images of a prototypical stellar wind-blown bubble have been used to infer general properties of this class of object. In particular, I explore the spatial relationships between warm thermally emitting dust, the polycyclic aromatic hydrocarbons-dominated photo-dissociation region, and ionized hydrogen gas, and use these to compare with bubble evolution models. This bubble appears to be <106 years old. Candidate YSOs and the ionizing star are identified using a grid of spectral energy distribution models for YSOs and main sequence and giant stars. The location of the candidate YSOs on the rim of the HII region and the association with an infrared dark cloud suggest that several of the YSO candidates have been triggered by the expansion of the HII region.
