Oral Session #34 at the 191st meeting of the American Astronomical Society inWashington DC will be devoted to recent discoveries about the nature of the extremely luminous and massive star Eta Carinae. This session will highlight new radio, near-IR, optical, and X-ray observations prior to (and during?) the predicted "spectroscopic event" expected to occur in early 1998, along with implications for the single-star-vs-binary star models. This session will also include contributions discussing the nature and origin of the extended nebulosity around the star.
