Most of the strange galaxies on this list are known to astronomers by two classifications: the Messier catalog or the New General Catalog. Messier’s catalog was compiled in 1771 by French astronomer Charles Messier as a way to organize the host of cosmic discoveries happening at the time. A particular fan of comets, Messier made the list with his assistant Pierre Méchain to filter out non-comet items. The New General Catalog (NGC) of Nebulae and Clusters of Stars is a collection of various types of deep sky objects compiled by John Louis Emil Dreyer. Numerous revisions have cleaned up the listing, now one of the most comprehensive catalogs to date with 7,840 deep space objects. From a galaxy which resembles a cosmic sunflower unfolding before our eyes to a hellish-looking mass of gas and matter to violent galactic collisions which seem oh-so-peaceful in still images, here are the 25 Most Bizarre Galaxies in the Universe.
