Explanation:
Detailed explanation-1: -The main reason we put telescopes into space is to get around the Earth’s atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. Our atmosphere acts like a protective blanket letting only some light through while blocking others. Most of the time this is a good thing.
Detailed explanation-2: -Hubble flies around, or orbits, high above Earth and its atmosphere. So, Hubble can see space better than telescopes on Earth can.
Detailed explanation-3: -The Earth’s atmosphere blurs our view of the cosmos. It also blocks certain types of radiation. For an unobstructed view, you need to be above the atmosphere. That’s why we launch telescopes into space.
