Before Watching
Ask students what kind of objects they see when they look up into the sky. Review the visible objects students might see—such as stars and planets—as well as the ones they probably don't—including galaxies and supernovae. Discuss what a light year is and tell students that the farther away that astronomers detect radiation, the closer they are to seeing what the beginning of the universe was like. Have students record how scientists in the program react to the news of discoveries. Do scientists dismiss them or find discoveries exciting?
After Watching
Discuss the benefits or drawbacks to having different approaches to measuring the universe. What are the advantages or disadvantages to the competition among scientists to be first in a discovery? Review students' observations about how scientists in the program approached and interpreted their data and the data collected by other scientists. Why might scientists react differently? How do scientists deal with different interpretations of the same data?
