messier 57
"One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them" -J.R.R. Tolkien
Every Monday has been devoted to our ongoing series on Messier's objects for nearly a year now, and we've covered some spectacular objects, from open star clusters to spiral galaxies, from globular clusters to giant ellipticals, from star-forming nebulae to the rare starburst galaxy, and from the lone supernova remnant to Messier's greatest mistake. With 110 deep-sky wonders to choose from, each one tells its own unique story.
