<p>Create/expand category description</p> <p><b>New page</b></p><div>This category collects astronomical and astrophysical work on this wiki: observation and interpretation of stars, galaxies, quasars, the solar system and the wider universe, together with celestial mechanics.<br /> <br /> It overlaps deliberately with [[:Category:Cosmology]], which covers the origin and large-scale structure of the universe, and with [[:Category:Redshift]], which covers the interpretation of spectral shifts — the single most contested observational question in this literature, since almost everything the standard model says about distance, age and expansion rests on reading redshift as recession velocity.<br /> <br /> Entries include anomalous-redshift and quasar-association work in the tradition of Halton Arp, alternative accounts of stellar structure and energy generation, solar system dynamics and the exploded-planet literature, variable stars, pulsars, and observational challenges to accepted distance scales.<br /> <br /> [[Category:Theory &amp; Models]]</div>
