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.
What disadvantages does the Hubble Space Telescope have over ground-based telescopes?
You’ve probably seen HST pictures, and they really are much more detailed than you can get from the ground. The disadvantages are mainly to do with the hassle of operating in space. It’s much more expensive, so you can’t have such a large telescope. If things go wrong it’s much harder to repair them.
What are two advantages that the Hubble Space Telescope has 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.
What are 2 disadvantages for space based telescopes?
Disadvantages. Space telescopes are much more expensive to build than ground-based telescopes. Due to their location, space telescopes are also extremely difficult to maintain. The Hubble Space Telescope was serviced by the Space Shuttle, but most space telescopes cannot be serviced at all.
What is the advantage of using space telescopes over ground telescopes?
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 are the advantages and disadvantages of a space based telescope to an Earth based one?
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 and disadvantages of telescopes?
Advantages and Disadvantages of an Astronomical Telescope
- It creates large magnification,
- Superior resolving power per inch of aperture,
- Its field of view is wide,
- Superior performance in inferior conditions – image steadier,
- The image is free from aberration, not reflections or interruption of the light path,
What are three advantages to space telescopes?
Advantages. Clearer observations can be taken as the atmosphere does not affect it. There is no distortion due to twinkling, glow from the sky or the effects of light pollution. Wider wavelengths of the electromagnetic spectrum can be observed such as infrared, ultraviolet, x-rays and gamma rays.
What are the advantages of having a telescope?
- Superior revolving power per inch of aperture.
- Superior performance in inferior conditions – image steadier.
- Not reflections or interruption of light path.
- Near permanent optical alignment – minimum maintanance.
- Long focal ratios can mean use of longer focus, simplier, eyepieces.
What advantages do space telescopes have over earthbound telescopes quizlet?
What advantages do space telescopes have over earthbound telescopes? A space telescope that orbits above Earth’s energy-absorbing atmosphere is able to detect the entire electromagnetic spectrum.
What are problems with ground-based telescopes?
In addition, turbulent motion in the atmosphere blurs the light travelling through it, causing objects to twinkle and appear fuzzy. Another problem with ground-based telescopes is that they are subject to local weather conditions, and high clouds can ruin the chance of making any useful observations.
What are ground-based telescopes?
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. Parts like x-rays, gamma rays, infra-red and long radio waves.
What are disadvantages of optical telescopes?
The disadvantage is that the smaller optical telescopes cannot gather as much light, so they are not very powerful if you seek more distant objects like galaxies and nebulae.
What are the advantages of space based observatories such as Hubble versus those 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 does the Hubble telescope work better?
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 of placing telescopes in space quizlet?
What are the advantages of putting telescopes in space? allows us to observe the rest of electromagnetic spectrum that does not reach ground/sea level.
