Learning Space 103: The Fall lineup of New Stars

By on October 28, 2015 in

One of my favorite things to do with students in the late fall is to take them outside and point first to the Orion nebula, then to the Pleiades, and finally to the Hyades cluster, saying “these are snap shots in the evolution of open clusters.” Each of these systems is the home of young stars, but while the Orion nebula is very much a stellar nursery, with stars just 10 million years old or younger, the Pleiades, is more like a day care center with stars 100 million years old or younger. At the same time, Hyades is more like an afterschool program for stars 730 million years old or younger. All these systems are filled with celestial children. In their youth these stars still gather in clumps. But, as they age, the stars will drift apart until, as adults, they have no memory of the place they were born.
