TITLE "A Star's Life"
AUTO SELECT TEXT "Introduction" "Stars, like everything else in the"
"universe are born, live out their lives and die. Stars have"
"extremely long lifetimes, making it impossible for a human to"
"observe an entire stellar life cycle. But, you can look around"
"the sky and see examples of young stars, middle age stars and"
"old stars, all in one night."
AUTO SELECT TEXT "The Nursery" "Stars are born within a huge cloud of gas"
"and dust. This giant cloud is called a diffuse nebula. A diffuse"
"nebula is illuminated by the newly formed stars. The stars heat up the"
"gas and cause it to glow. Press MODE to view a ""stellar nursery""."
