What is a nebula? A nebula is a cloud of interstellar dust and gases that can be seen as either bright patches in the sky if light is being reflected off of it, or dark areas of the sky if the mass of dust and gases are blocking, or absorbing, the stars brightness from our vision.

In this article you will find a listing of the common names of nebulae beginning with the letters, A through C. When reading about the different nebula, you will discover that someone has been quite descriptive in choosing names. When looking at the nebula and then comparing them to everyday objects, names like Bug, Ant, Boomerang, Cat’s Paw and Crab were used. This group of nebula also includes the well-known Carina Nebula and the inspiring Cone Nebula.

This series on nebula was introduced in What is a Nebula? Part 1, Different Kinds of Nebula. In that article different classifications of nebula were discussed. Part 1 also contains a complete listing of all the nebulae. If you need to find information about a specific nebula, it can be located in that alphabetical listing. Clicking on it will take you directly to its picture and description.

Some of these just look too unreal. And yet, they are about as real as you can get. Looking at them is more beautiful than abstract art. There is no better artist, than Nature. Amazing hub, enjoyed it all the way through! I always been fascinated with the glowing arena of Nebulas! Thanks for sharing homesteadbound.

Jangaplanet - I too believe that these are truly beautiful. My favorite is V838 Monocerotis. It's pictures have always fascinated me. I hope you had a chance to look at the rest of this series including the one that has V838 Monocerotis. Nebulae are truly beauty that nature has provided for our pleasure. Thanks so much for stopping by!
