We report results from observations taken at different wavelengths (optical, radio and NIR) of the bipolar Protoplanetary Nebula OH 231.8+4.2. Radio interferometry with high spatial resolution has been particularly revealing. We study the complex structure and dynamics of this object as well as its rich chemistry.
