Teaching with the Show Visualizations of the Sun and Earth are
created from observations made by scientists using both ground-
based and space-based telescopes. To support a class discussion
after viewing Journey to the Stars , you may wish to review the
main content points from each section of the show and then use
the Guiding Questions - We live on a planet that orbits a star
that is one of hundreds of billions in our galaxy. - Our star,
the Sun, is a middle-aged yellow star of somewhat above average
mass. - Without nurturing light that carries energy from our
Sun, life as we know it would not exist. - And without the
elements formed by stars that lived and died billions of years
ago, we—and everything around us—would not exist. Scientists use
supercomputer models to understand star formation and star
clusters. The first stars were massive-they burned hot and
heated the surrounding gas (red, purple, white filaments). They
lived fast and died young in supernova explosions (white region
in center). 2. Stellar
