This page aims to list articles on Wikipedia that are related to astronomy, astrophysics and cosmology. This is so that those interested in the subject can monitor changes to the pages by clicking on Related changes in the sidebar. This list is not intended as an astronomical reference in its own right.
The list is not necessarily complete or up to date - if you see an article that should be here but isn't (or one that shouldn't be here but is), please update the page accordingly.
Three astronomy-related WikiProjects are being developed; please visit WikiProject Astronomical Objects, WikiProject Constellations, and WikiProject Telescopes.
