Are Nebulae within or outside of our galaxy Nebula comes from a Greek word meaning Cloud April 1920 National Academy of Sciences Washington DC Harlow Shapley had determined size of Milky Way Galaxy pushed that nebulae were relatively close by objects.

This compilation of data on deep-sky objects covers Messier objects, New General Catalogue objects and Index Catalogue objects. These are classified as galaxies, clusters and nebulae of which 500 individual objects are listed. Observing the deep-sky beyond the limits of the Solar System is by far the most popular speciality for amateur astronomers. Two major catalogs of deep-sky objects are widely used: Messier\'s catalogue of 109 objects and the New General Catalog (NGC) which contains thousands of objects. This catalog has entries for each of more than 500 deep-sky objects - all the Messier objects plus selected NGC objects. As well as the usual astronomical data they also detail physical factors, astrophysical information, evolution, ans unusual features. The objects are all listed in NGC order, which were originally assigned in approximate order of location from west to east, convenient for reference because objects that can be seen on a given night will occur within a few pages of each other in the book. Have Fun Exploring the Stars with Close-up Views of Space Objects Right from Your Own BackyardIt doesn’t take an astronomy degree to feel like an astronaut and explore space with a small telescope. See It with a Small Telescope takes the mystery and struggle out of exploring the unknown and discovering new worlds! With hands-on tips and tricks, this book offers a complete guide to unleashing the full power of a small telescope and going beyond the basics.Without technical jargon and complicated star charts, this book offers step-by-step instructions and easy-to-use illustrations for finding over 100 celestial objects in the night’s sky, including:Saturn’s RingsJupiter’s MoonsOrion Nebula Andromeda GalaxyPolaris Double StarPegasus Globular ClusterApollo 11 Site...and more! A rare look at the southern skies\' greatest glories.The celestial objects of the Southern Hemisphere are fascinating to astronomers everywhere. The southern stars, nebulae, and galaxies have exotic names like Omega Centauri, the Tarantula Nebula, Canopus, the Vela Supernova, the Coal Sack, and the Magellanic Clouds.And there\'s more: the Southern Milky Way is crammed with clusters and nebulae of great interest to resident astronomers of the southern hemisphere, and to the many visitors from the north who relish the opportunities to view the clear, dark skies of the interiors of southern Africa and Australia with binoculars, telescopes and cameras.Pearls of the Southern Skies depicts 71 Deep Sky Objects photographed by Dieter Willasch and described in detail by Auke Slotegraaf. The text and pictures are laid out season by season, and accompanied by 15 easy-to-use full-color location charts.
