Nebulae and Other Star Birthplaces

This page focuses on the captivating nebulae and other cosmic structures that form stars, many of which have interesting nicknames! Each listing lists the constellation that the star-forming region is in, and some listings might have a link to an image from Hubblesite.org, NASA's Astronomy Picture of the Day, or another website.
