Answer 1

Answer:

1. telescope

2. astronomers

3. radio waves

Explanation:

A telescope allows one to magnify what they're looking at to see it closer than it actually is. Astronomers are those that study planets, stars, and other celestial bodies in space. Modern telescopes have the ability to detect radio waves from astronomical objects that emit them from far away.  This allows us to see what we normally would not be able to.
