3. Hold the piece of paper with the smaller hole up to the screen. What do you notice?
This represents what the Hubble Space Telescope can see.
4. Hold up the piece of paper with the larger hole up to the screen. What do you notice?
This represents what the Nancy Grace Roman Telescope will see.
5. Compare what you can see with the two viewers.
- How does using each viewer change what you see?
- How many of the small viewers would it take to cover the whole image? How many larger viewers?
- Which viewer helps you focus on a single detail? How could that help a scientist?
- Which viewer helps you see many details together? How could that help a scientist?
- Which would you use to explore the universe? Which would you use to look carefully at a star? Why?
6. Bonus! Repeat the activity looking at a different picture of the universe or take both viewers outside to look a the night sky. What do you notice?
