Why do we put telescopes in space quizlet?

Why do astronomers put telescopes in space? Scientists have placed telescopes in space in order to avoid the interference of our atmosphere caused by air and light pollution. Also, most of the electromagnetic waves are blocked by our own atmosphere.

Why do we put telescopes in the 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.

What is the best reason to put a visible light telescope in space instead of on the ground quizlet?

What is the best reason to put a visible-light telescope in space instead of on the ground? The telescope is above the atmosphere so the light does not get distorted by turbulent air. What does the technique of interferometry allow?

What do astronomers do with telescopes quizlet?

Telescopes enable astronomers to observe many more stars than they could with their eyes alone. Telescopes gather and focus light from objects in space. Astronomers use many kinds of telescopes to study the energy emitted by stars and other objects in space.

Why is it better to place telescopes on a satellite in space rather than placing them on the ground?

Space-based telescopes like Hubble get a much clearer view of the universe than most of their ground-based counterparts. They’re also able to detect frequencies and wavelengths across the entire electromagnetic spectrum.

Why are some telescopes located in space instead of on Earth’s surface quizlet?

Telescopes located outside earth’s atmosphere; located there because there is less light distortion caused by atmosphere; able to collect energy or information that doesn’t pass through earth’s atmosphere; Photo: Hubble Space Telescope orbiting earth. You just studied 15 terms!

Why are most large telescopes reflecting telescopes?

* Refracting telescopes collect light using lenses. Reflecting telescopes use mirrors to bring light to a focus. All large telescopes are reflectors because large lenses are expensive to make and because large lenses sag under their own weight.

Which of the following is one important reason why most large astronomical telescopes are reflecting telescopes rather than refracting telescopes?

Astronomers prefer reflecting telescopes because larger mirrors are lighter and much easier to construct than large lenses, and they also suffer from fewer optical defects.

How do telescopes help us learn about the universe quizlet?

HOW DO TELESCOPES HELP US LEARN ABOUT THE UNIVERSE? We can see fainter objects and more detail than we can see by eye. Specialized telescopes allow us to learn more than we could from visible light alone.

What is the primary purpose of interferometry quizlet?

What is the purpose of interferometry? It allows two or more small telescopes to achieve the angular resolution of a much larger telescope.

What a telescope is used for?

Telescopes collect and magnify the light from distant objects. The problem with observing objects in the night sky is that they are so far away and therefore appear extremely faint. The more light that can be collected with a telescope, the better we can see these objects.

Why do telescopes in space give better images than telescopes on the Earth?

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.

Why can telescopes see further into space and get more detailed images of the universe?

Earth’s atmosphere alters and blocks the light that comes from space. Hubble orbits above Earth’s atmosphere, which gives it a better view of the universe than telescopes have at ground level.

What are the advantages and disadvantages of placing telescopes in space?

In space, however, telescopes are able to geta clearer shot of everything from exploding stars to other galaxies. Another disadvantage for ground-basedtelescopes is that the Earth’s atmosphere absorbs much of the infrared andultraviolet light that passes through it. Space telescopes can detect thesewaves.
