Transcript of Evolution of telescopes

Galileo telescope
Galileo made the first telescope in 1609.
Galileo's telescope concentrated light to make celestial objects able to be seen better than the human eye. The two lenses consisted concave and convex lenses.
Multi-Mirror telescope
People could not make the mirror in telescopes bigger than 200 inches without distorting the image, so they made a giant mirror by adding many mirrors to create a single image. These became known as multi-mirror telescopes.
Radio Telescopes
Using parabolic reflectors, or dishes, radio waves bounce off and meet at a focal point. A receiver captures them, amplifies them, then sends to a computer to store data. These are called Radio Telescopes.
Solar telescopes
Astronomers used ordinary reflectors to study the sun, but the light gathered was too much to make it able to study. So they readjusted the lenses so it captures the right amount of light. They called these solar telescopes.

What are Telescopes?
A telescope is a concave and convex
mirror connected by a cylinder. The
light gathered is met at a focal point
and looks bigger. This makes things
easier to study than with the human
eye.
