How do telescopes benefit us?

jst search it in Google. lol

1. The aperture of a telescope is several times larger than the aperture of human eye so that the objects that can not be normally seen by unaided eye can be seen. Light- gathering power of a telescope is proportional to the area of its aperture and hence depends on the square of the radius of the mirror. Therefore a 20 cm diameter telescope collects four times more photons than a 10 cm diameter telescope.

2. A telescope can be equipped to record light over a long period of time, by using photographic film or electronic detectors such as photometers or CCD detectors while the eye has no capability to store light. A long-exposure photograph taken through a telescope reveals objects too faint to be seen with the eye, even by looking through the same telescope.

3. A third major advantage of large telescopes is that they have superior resolution, the ability to discern fine detail. Small resolution is good. The resolution is directly proportional to the wavelength being observed and inversely proportional to the diameter of the telescope.

Telescopes have changed the way man views himself in relation to the Universe. It is responsible for many important discoveries like determining the orbits of the planets in our solar system. The Hubble telescope shows us billions of galaxies, with billions of stars in each one. We can see the birth and death of stars, so we know what will happen to our own star in a few billion years. We watched the impact of the Shoemaker-Levy into Jupiter, we're seeing Mercury up close now, and Cassini is looking at Saturn and her moons. We may find life in some of these moons. We could never reach out as far as we have in the Universe without our telescopes.

It helps us see things that our eyes could not see from a far sight. It makes a image byfocusing on light that reflects on to its mirrors and then you have a clear image. If we did not have this amasing invetion we could not have binoculars and never get to see oter space from earth!

Answer 5

Telescopes allowed astronomy to take a huge leap forward when Galileo first pointed a telescope into the sky (he did not invent the telescope, but was the first to use it to observe celestial objects and record his discoveries) and was able to see things that could not be seen by the naked eye.

Answer 6

with out the telescope we would think that earth was the only planet and there was no solar systems or no galaxies

Answer 7

Easier to be a peeping Tom at a distance.
