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 are the advantages and disadvantages of having 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.
What is the biggest disadvantage of putting a telescope in space?
Which of the following is the biggest disadvantage of putting a telescope in space?
Space telescopes are much more expensive than similar ground-based telescopes
.
What are the 3 disadvantages of ground-based telescopes over space telescopes?
- Lower Cost. Ground-based telescopes cost about 10 to 20 times less than a comparable space telescope. …
- Maintenance Issues. …
- Site Requirements. …
- Image Quality. …
- Deficient Data.
What are some problems with telescopes?
- Chromatic abberation. The red and blue light focusses at different locations creating coloured halos. This occurs because the path taken by blue light through glass bends more than red light. …
- Lens distortion. A very large glass lens will tend to become distorted due to its own weight.
What are two advantages of putting a telescope in space?
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 some disadvantages to using visible light to study objects in the universe?
| Table 1. Recent Observatories in Space | Observatory Date Operation Began Bands of the Spectrum | Hubble Space Telescope (HST) 1990 visible, UV, IR | Chandra X-Ray Observatory 1999 X-rays | XMM-Newton 1999 X-rays |
|---|
What is the consequence of seeing on ground based telescopes?
To see the bulk of galaxies actually forming would require the removal of a last and major limitation of telescopes of modest size: all images observed with ground based telescopes are
affected by the image blurring that occurs as the light travels the last tiny fraction of its journey from the galaxies through the
…
What is the main drawback of earth based optical telescope?
Can receive only visible light/ radiation
.
Cloud over in Earth’s atmosphere can be a barrier
.
City lights put limitations
.
What are three advantages of using a space based telescope such as Hubble over land 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.
Are telescopes bad for the environment?
TMT officials say the world’s largest telescope will be a
zero-waste facility
, while the state has determined it doesn’t pose a risk to the Big Island’s water supply. … A 1998 state audit found that observatories left trash and old equipment and damaged historical sites and endangered species candidate habitat.
What are the pros and cons of reflecting telescopes?
| Pros Cons | Large mirror = better light collecting capacity No chromatic aberrations (colored fringes around stars) Relatively low cost Optical quality often disappointing Collimation and mirrors cleaning processes Open tube = high vulnerability to dust, humidity..etc Bulky and heavy |
|---|
What are the pros and cons of telescopes?
- 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,
How many space telescopes are in space?
| Name Space agency Location | Hipparcos ESA Earth orbit (223–35,632 km) | Hubble Space Telescope NASA & ESA Earth orbit (586.47–610.44 km) | MOST CSA Earth orbit (819–832 km) | Swift Gamma Ray Burst Explorer NASA Earth orbit (585–604 km) |

How does seeing affect resolution?
Seeing is a major limitation to the angular resolution in astronomical observations with telescopes that would otherwise be limited through
diffraction by the size of the telescope aperture
. … A seeing disk smaller than 0.4 arcseconds or a Fried parameter larger than 30 centimeters can be considered excellent seeing.
Which of the following telescopes would not be suitable for ground-based observations?
Which of the following telescopes would not be suitable for ground-based observations: Only
X-ray telescope and ultraviolet telescopes
above would not be suitable.
What are refractor telescopes good for?
Refractor Telescope
They are ideal for
viewing larger, brighter objects such as the Moon and planets
. Pluses for refractor telescopes include “right-side-up” images, the ability to come to thermal stability quickly meaning low image distortion, and a sealed tube which means little maintenance is required.
How did Mauna Kea affect the environment?
Another concern is the telescope’s potential impact on wildlife. Not many animals can live on the 13,796-foot peak of Mauna Kea. But in the past, telescope development has restricted
the habitat of the Wekiu bug
, contributing to its being listed as a candidate for an endangered species until 2011.
What is a major disadvantage of a refracting telescope?
Disadvantages. All refractors
suffer from an effect called chromatic aberration (“color deviation or distortion”)
that produces a rainbow of colors around the image. … This is why the early refracting telescopes were made very long.
Are radio telescopes affected by pollution?
So it is less well known that radio telescopes are
jeopardized by invisible electromagnetic pollution
, not just sources like TV transmitters but from garage openers and other devices that have stronger signals than do twitches from millions of light years away.
Is the Mauna Kea telescope nuclear?
TMT will be connected to the local Hawaii Island power grid, just like the other observatories currently on Maunakea. Will nuclear power be used?
No
.
Why do scientists need space telescopes?
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.
Why are bigger telescopes better?
“The bigger a telescope is,
the more light it can catch and the better the sharpness of the image becomes
.” Larger telescopes enable astronomers to observe fainter objects. … Larger telescopes also enable astronomers to observe and analyze planets around distant stars – and maybe find another Earth out there.
Is refractor or reflector telescope better?
If you are interested in astrophotography, purchasing a refractor is a better option because of it’s specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a
reflector telescope is ideal
.
What is the name of NASA’s space telescope?
NASA launched
the James Webb Space Telescope
on Saturday, after years of delays and budget hikes. Webb is 100 times more powerful than the Hubble Space Telescope and expected to revolutionize astronomy. The telescope must first unfold itself in space, travel 1 million miles, and calibrate its instruments.
What is the name of NASA’s most famous space telescope?
| Names HST Hubble | Mission type Astronomy | Operator NASA · STScI · ESA | COSPAR ID 1990-037B | Spacecraft properties |
|---|
Where are space telescopes located?
Launched on April 24, 1990, aboard the Space Shuttle Discovery, Hubble is currently located
about 340 miles (547 km) above Earth’s surface
, where it completes 15 orbits per day — approximately one every 95 minutes.
