- Why is it so difficult to see planets around other stars?
- Why did the Americans think it was impossible for a gas giant to have a 4-day orbit?
- Discuss how it was possible for planets to be "hiding" in the astronomers' data. What did the American scientists find when they re-analyzed their own data, which they had been collecting for years?
- At the beginning of the video, our Sun is shown as being very close to its planets (including Earth) and barely larger than them. Considering proportions, distance, and the imaginary blue lines, what is wrong with the representation? How might it be shown more accurately?
- What does this video tell you about the processes of science?
