These are hot, young, blue stars all traveling together as a group. Binoculars will reveal some gas around the young stars. Now look nearly overhead and you will see a yellowish star called Capella in the constellation Auriga the Charioteer. This star is a middle aged yellow star, much like our star, the Sun. It is actually a multiple star system and binoculars will reveal one of Capella's companions.
Many stars are double and multiple systems.
Some only appear double due to line of sight, while other stars actually revolve around each other and form a physical pair bound by gravity. There are a number of good examples of stars in the senior age status. Stars can meet their ends in a few different ways all of which depend on one thing, their mass. The more massive a star, the faster it evolves. Stars which are about half the size of the Sun burn up their hydrogen and then slowly cool down.
