Another popular attraction is a Nebula. Nebula's are large clouds of dust and gas held together by gravity. There are also two types of nebula we visit the planetary and stellar. Stellar Nebula's are clouds of dust and gas with a lush collage of colors where star are made. Planetary Nebula's are completely different, they are beautiful shells of gas that surround a star near the end of its life cycle.
