Comparing Physical Properties of Nebulae of Various Classifications

Science Update

What we see with our eyes is often an incomplete story of what a nebula can tell us about itself. Students at the University of Nevada, Reno used the Great Basin Observatory to study six nebulae in an effort to connect their classification to physical properties, such as density and temperature. Students observed three types of Nebulae; an emission nebula, which is a giant cloud of ionized gas that emits light in different wavelengths; a supernova remnant, which is the enriched corpse of a giant star that ended its life in a supernova explosion; and a planetary nebula, which is the slowly shed outer layers of a dead star.
