Question 1

What is the biggest problem in gathering radiation from space to study universe?

Answer 1

air

Question 2

What does the earth’s atmosphere do to make it difficult?

Answer 2

interferes with light rays, completely blocks many EM radiation so they cannot be studied from the surface

Question 3

Twinkling starlight reason?

Answer 3

due to light rays being jiggled and deflected as they come though the shifting atmosphere.

Question 4

What does twinkling starlight effect?

Answer 4

For astronomers, limits the clarity and accuracy of their measurements and observations

Question 5

How do they avoid the problem of earths atmosphere interference?

Answer 5

Optical telescopes built on top of high mountains, putting them above the most unstable and densest part of atmosphere so they get a clearer view.

Question 6

Why use satellite astronomy?

Answer 6

EM radiations completely blocked by the atmosphere

Question 7

What cant you use to study useful astronomy on ground level?

Answer 7

infrared, X-ray, gamma and arts of microwave and UV spectrum.

Question 8

What is the solution for the block of EM radiation?

Answer 8

Modern astronomy done from satellites, only solution for some type of observations
