|Our sun, and other stars like it, do not remain exactly as they appear now. Stellar lifetimes are much longer than ours, but like us, they progress though stages of life. The story of these stages tells us about the formation of the planets and their fate in the events to come billions of years from now. In this tour, we investigate the life cycle of stars like our sun.|
