Discussion questions

Discussion

"Cosmic Dawn" follows the people who built the James Webb Space Telescope over many years.

  1. Webb is designed to see the very first galaxies. Why do we need such a huge, powerful telescope to do that?
  2. What are some problems the team had to solve before Webb could work in space?
  3. Building Webb took decades of teamwork. What does that tell you about big science projects?
