Considerable efforts have been expended trying to model the structure of the heliosphere, with some degree of success. The Voyager 1 spacecraft crossed the heliospheric termination shock at a distance essentially consistent with many of the models and much of the basic physics appears to be understood. The first discovery of one the heliospheric boundaries was however made some years before with the detection of the hydrogen wall using (for space physics) the novel technique of Lyman-alpha absorption measurements by the GHRS instrument on Hubble. The unexpected additional absorption of Lyman-alpha photons by the heliospheric hydrogen wall enabled estimates of the size and properties of the heliosphere that are consistent with the Voyager 1 observations and, furthermore, provided a tool to explore related observations to nearby stars. Consequently, previously unmeasurable stellar winds from solar-like G stars have been detected using this technique and the properties of the winds have been inferred. This talk will review and highlight the relationship between the understanding and modeling of our heliosphere and the extension of these models to other interstellar environments, to other stellar winds and astrospheres, and to planetary nebulae.
