Why is the Hubble telescope located in space?

• So it can be closer to the stars it magnifies
• They have very large optical lenses
• So its images arent distorted by Earth's atmosphere 
• So it can be operated by astronauts 

What are disadvantages of refracting telescopes (choose all)

• images are wrong color

• images are more blurry

• gravity can distort the lens

• images may be too big

Who invented the telescope?

• Galileo Galilei

• Isaac Newton

• Hans Lippershay

• Maria Mitchell
