We present new high-resolution infrared and optical imaging and spectroscopy of Eta Carinae and its complex circumstellar nebulosity. Diffraction-limited IR images reveal several new structures in the core of the nebula, possibly associated with a compact but disrupted circumstellar dust torus. These images help to clarify a recent controversy regarding the nature of the IR structures around Eta. We compare the structures seen in thermal-IR images to near-IR and optical images and spectra from HST and ground-based observatories.
