Exploration Questions: Stars

1. What causes a star to form? What causes it to die?

2. Hayden Planetarium Director Neil deGrasse Tyson advised DC Comics on an episode in which Superman uses a powerful telescope to watch the destruction of his home planet Krypton. Is it really possible to look back in time by looking through a telescope? Why or why not? Why did Dr. Tyson suggest a star 27 light-years away?
