Human Star

Fetus Protostar

Growing Child/Young Adult Main Sequence

Late Adulthood Red Giant

Death White Dwarf/Black Hole/Neutron Star

Spectroscopy

Spectroscopy is a technique used to explore stars and other phenomena found in space. Much of what we know about astronomy uses this tool, and this part will explain this technique as well as connect our understanding of light to what we know about the universe.
