How are telescopes used to study stars?

Telescopes launched into space represent the next phase of studying stars. Space telescopes orbit the Earth but are programmed to study stars in various ways. Other telescopes detect X-rays, given off when neutron stars pull material into their gravity.

What can telescopes tell us about stars?

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.

How does a telescope track stars?

The telescope is at one end of the declination axis and it is balanced by a counterweight at the other. With this arrangement once an astronomer has pointed the telescope at a star or other celestial body, he or she can follow the motion of the stars by a simple movement of the telescope around the polar axis.

How do space telescopes work?

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 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.

What can you see in space with a telescope?

The Webb Telescope is an infrared telescope, meaning it uses infrared radiation to detect objects in space. It is able to observe celestial bodies, such as stars, nebulae and planets, that are too cool or too faint to be observed in visible light — what is visible to the human eye.

Why are a lot of space telescopes built on mountains?

Most important, putting an observatory on a mountaintop means there’s less air to see through, so the “seeing” is better. On a mountaintop, there’s also less air above you to absorb light from the stars.
