The sun is our life-giving source of light, heat, and energy, and new discoveries are unraveling its epic history. Join NOVA on a spectacular voyage to discover the sun's place in a grand cycle of birth, death, and renewal that makes this the age of stars. Witness how stars of every size and color came to populate our universe; how stars stage a dramatic exit when they explode as supernovae, which can outshine an entire galaxy; and how, billions of years in the future, the age of stars will lead ultimately to an age of darkness.
