What advantages does the Hubble space Telescope have over ground-based telescopes?
The Hubble telescope provides four key advantages over most other optical astronomical facilities: unprecedented angular resolution over a large field, spectral coverage from the near infrared to the far ultraviolet, an extremely dark sky, and highly stable images that enable precision photometry.
Why are telescopes in space better at producing images?
Why is Hubble able to see so much better than telescopes on Earth? Because it is above the Earth’s atmosphere. The atmosphere disturbs the starlight (a bit like looking through water) and blurs the images. So Hubble’s images are much sharper than those from other telescopes.
Why is the Hubble Space Telescope so important?
The telescope has helped scientists understand how planets and galaxies form. Galaxies contain billions of stars. A picture called “Hubble Ultra Deep Field” shows some of the farthest galaxies ever seen. And Hubble has helped scientists learn more about explosions that happen when huge stars burn out.
What is not an advantage of the Hubble Space Telescope?
Which of the following is not an advantage of the Hubble Space Telescope over ground-based telescopes? It is closer to the stars. Which of the following wavelength regions cannot be studied with telescopes on the ground? Telescopes operating at this wavelength must be cooled to observe faint astronomical objects.
Why do space telescopes yield sharper images than ground-based telescopes?
Space-based telescopes like Hubble get a much clearer view of the universe than most of their ground-based counterparts. Ground-based telescopes can’t do the same, because the Earth’s atmosphere absorbs a lot of the infrared and ultraviolet light that passes through it.
Why are some telescopes placed in 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.
Why do we need ground based telescopes?
Most telescopes used by astronomers are on Earth. A telescope on the ground has to look through the Earth’s atmosphere to see into space. This is a problem because the atmosphere can blur our images. The air also blocks out light from parts of the electromagnetic spectrum.
Why do we use space telescopes?
Telescopes are placed into orbit around the Earth or are sent farther out into space to get a clearer view of the Universe. There are many different types of space telescopes. Some are used to study a special object like the Sun. Others are used to study the different types of light given off by objects in space.
What are the advantages and disadvantages of space based telescopes?
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.
What are the advantages of a ground-based telescope?
Compared to space-based telescopes, ground-based telescopes have much to offer. They can be built bigger and for less money. They’re easier to maintain and upgrade. Practically speaking, they also have a much lower risk of being damaged by one of the 500,000 pieces of debris flying through the cosmos—or space junk.
What are the advantages and disadvantages of using a Space Telescope?
In space, however, telescopes are able to get a clearer shot of everything from exploding stars to other galaxies. Another disadvantage for ground-based telescopes is that the Earth’s atmosphere absorbs much of the infrared and ultraviolet light that passes through it.
Is it possible to use a Space Telescope on Earth?
Sure, flying above the atmosphere and receiving the omnidirectional perspective that going to space gives you are definite victories for the space telescope aficionados; there’s no way adaptive optics or a pristine observing site can compete with an observatory that doesn’t have the Earth to contend with.
How do space telescopes detect the Earth’s atmosphere?
Space telescopes can detect these waves. Newer ground-based telescopes are using technological advances such as adaptive optics to try to correct or limit atmospheric distortion, but there’s no way to see the wavelengths that the atmosphere blocks from reaching Earth,…
