Emission and Reflection Nebulae

Nebulae are clouds of interstellar gas where stars are born as the gaseous material condenses into a tightly packed mass. Emission nebulae have one or more bright stars nearby that cause the gases to emit energy primarily in the reddish hydrogen-alpha part of the spectrum. Reflection nebulae have one or more bright stars nearby but not close enough to cause emission, and only bluish light from the stars is reflected.

Planetary Nebulae

These deep sky objects are tiny and not like the large emission and reflection nebulae where stars are born. A planetary nebula is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from a star late in its life, and only exists for a few tens of thousands of years. They are also not related to planets, but were given this name when first discovered in the 1700s because they resembled the size and shape of planets.

Star Clusters

Loose star clusters appear to be associated as stellar groupings in the sky, but often are separated by greatly different distances from the earth. Note the blue nebulosity around the stars of the Pleiades. Globular clusters do form a spatially connected group, and often there more than a million stars in a single cluster. Galaxies contain hundreds of billlions of stars.
