  We report results from a Hubble Space Telescope (HST) and Near-Infrared
Camera and Multiobject Spectrometer (NICMOS) program to study the distribution
of hot neutral (molecular hydrogen) and ionized circumstellar material in the
young planetary nebulae NGC 7027. HST/NICMOS provided very high spatial
resolution imaging in line and continuum emission, and the stability and large
dynamic range needed for investigating detailed structures in the circumstellar
material. We present dramatic new images of NGC 7027 that have led to a new
understanding of the structure in this important planetary nebula. The central
star is clearly revealed, providing near-infrared fluxes that are used to
directly determine the stellar temperature very accurately (T = 198,000 K). It
is found that the photodissociation layer as revealed by near-infrared
molecular hydrogen emission is very thin, and is biconical in shape. The
interface region is structured and filamentary, suggesting the existence of
hydrodynamic instabilities. We discuss evidence for the presence of one or more
highly collimated, off-axis jets that might be present in NGC 7027. The
evolutionary future of NGC 7027 is discussed.
