In a nod to the global amateur astronomy community, as well as to any space enthusiast who enjoys the beauty of the cosmos, the Hubble Space Telescope mission is releasing its version of the popular Messier catalog, featuring some of Hubble’s best images of these celestial objects that were once noted for looking like comets but turned out not to be. This release coincides with the Orionid meteor shower—a spectacle that occurs each year when Earth flies through a debris field left behind by Halley’s Comet when it last visited the inner solar system in 1986. The shower will peak during the pre-dawn hours this Saturday, Oct. 21.
