How do optical telescopes work to view objects in space?

A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. The bigger the mirrors or lenses, the more light the telescope can gather. Light is then concentrated by the shape of the optics.

How are optical telescopes used in space science?

Telescopes are placed into orbit around the Earth or are sent farther out into space to get a clearer view of the Universe. Others are used to study the different types of light given off by objects in space. X-ray and gamma-ray telescopes study the hottest and most explosive objects in space.

Why do scientists use telescopes to view space?

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.

How do optical telescopes help scientists?

For example, telescopes are helping with monitoring the meteors and asteroids, which potentially could pose a threat to Earth. A telescope is used to see objects far away, but we often think of telescopes as scientific instruments, we look through and get an image, through some optics.

What are optical telescopes used for?

Optical telescopes are used for astronomy and in many non-astronomical instruments, including: theodolites (including transits), spotting scopes, monoculars, binoculars, camera lenses, and spyglasses. There are three main optical types: 1. The refracting telescope which uses lenses to form an image.

How do scientists use telescopes to study the origins of the universe?

Telescopes have also helped us understand the light that radiates from the sun and other stars. Some new telescopes allow us to study objects in the universe by detecting the heat or radio waves or X-rays they emit. Telescopes are now discovering planets around other stars.

Why do optical telescopes work better in space?

Space telescopes have the advantage of being above the blurring effects of the Earth’s atmosphere. In addition, there are many wavelengths from the electromagnetic spectrum that do not reach Earth because they are absorbed or reflected by the Earth’s atmosphere.

What do optical telescopes do?

An optical telescope is a telescope that gathers and focuses light mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct visual inspection, to make a photograph, or to collect data through electronic image sensors.

How is an optical telescope useful?

People use optical telescopes (including monoculars and binoculars) for outdoor activities such as observational astronomy, ornithology, pilotage, hunting and reconnaissance, as well as indoor/semi-outdoor activities such as watching performance arts and spectator sports.

What do scientists use telescopes for?

Astronomers use telescopes to detect the faint light from distant objects and to see objects at wavelengths all across the electromagnetic spectrum.

How does a optical telescope work?

Optical telescopes allow us to see further; they are able to collect and focus more light from distant objects than our eyes can alone. This is achieved by refracting or reflecting the light using lenses or mirrors. This second lens is then responsible for focusing that light to produce a clear image of the object.
