Question 1:
Why are telescopes placed in space?

Student answers will vary. Some students might say that space telescopes can see objects more clearly because they are above the blurring effect of Earth's atmosphere. Other students might say that space-based infrared telescopes are important because space is the best place to do infrared astronomy. Earth's atmosphere glows brightly in infrared light, making it difficult to accurately measure light from faint celestial infrared objects.
