What advantage if any would radio astronomers have by building their telescopes at the tops of mountains?

Why do optical astronomers often put their telescopes at the tops of mountains, while radio astronomers sometimes put their telescopes in deep valleys? They build telescopes at the tops of mountains to avoid light pollution and better resolution.

Why do astronomers build radio telescopes?

We use radio telescopes to study naturally occurring radio light from stars, galaxies, black holes, and other astronomical objects. We can also use them to transmit and reflect radio light off of planetary bodies in our solar system.

Why are telescopes in different locations working together especially desirable for radio telescopes?

Why are telescopes in different locations working together especially desirable for radio telescopes? Because radio telescopes have such poor resolution. Additional telescopes in between the two farthest-separated telescopes increases the gathering power and resolving power of the effective telescope.

What are the advantages of making a telescope mirror thin What problems result quizlet?

What are the advantages of making a telescope mirror thin? What problems does that cause? Advantage is that it’s lighter, but thin mirrors distort images less and have a lesser weight. If the mirror isn’t very thin, you can expect your image to be distorted and it can take longer to achieve the image you want or need.

Why put a telescope on a mountain?

The reason large telescopes are built on tall mountains or put in space is to get away from the distortion of starlight due to the atmosphere. Because of the elevation, the telescopes are above most of the water vapor in the atmosphere, so infrared astronomy can be done.

Can optical telescopes penetrate interstellar dust?

The center of our Milky Way galaxy is hidden from the prying eyes of optical telescopes by clouds of obscuring dust and gas. But in this stunning vista, the Spitzer Space Telescope’s infrared cameras penetrate much of the dust, revealing the stars of the crowded galactic center region.

Why can’t humans see radio waves?

You can see visible light because the visible-light photons travel in small waves, and your eye is small. But because radio waves are big, your eye would need to be big to detect them. They then turn those radio waves, which human eyes cannot see, into pictures and graphs that scientists can interpret. Source: NRAO.

Can humans see radio waves?

The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays — all of which are imperceptible to human eyes.

Which telescope has the best resolution?

The Hubble Space Telescope
Answer: The Hubble Space Telescope (HST) has a highest resolution of about 0.03 arcseconds, while the Very Long Baseline Array (VLBA) makes images with a resolution smaller than 0.001 arcsec. So, the VLBA has the HST beat when it comes to picture resolution.

What are the 3 main types of telescopes?

There are three main types of telescope. These are refracting telescopes, Newtonian telescopes and Schmidt-Cassegrain telescopes.

Why do astronomers not like beautiful sunsets?

Most people like beautiful sunsets with brightly glowing clouds, bright moonlit nights, and twinkling stars. – There are no clouds, which scatter or block light. – Bright moons cause light pollution, which is why astronomers don’t like bright full moons.

Why do single dish radio telescopes have poor resolution?

Why do single-dish radio telescopes have poor resolving power compared to optical telescopes of the same diameter? Because the size of diffraction fringes is proportional to the wavelength of light being focused, and radio waves have longer wavelengths than visible light.
