- The earth’s atmosphere. The first advantage?
- The detail is absolutely extraordinary.
- It points to the potential of the space program.
- Operating in space.
- Time consuming.
- Expensive.
- Repairs are difficult.
- Out of date.
What is one disadvantage for having the Hubble telescope in space?
Disadvantages
. There are some limitations with the
Hubble Space Telescope
when imaging the Moon due to its sensitivity to light and it cannot image areas in the direction of the Sun. They are exceptionally expensive to build and position in place. Maintenance is difficult.
What are 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 and disadvantages of a 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 some advantages of the Hubble Space Telescope?
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.
Can we see Hubble from Earth?
Hubble is best seen
from areas of the Earth that are between the latitudes of 28.5 degrees north and 28.5 degrees south
. This is because Hubble’s orbit is inclined to the equator at 28.5 degrees. … In contrast, the ISS passes over much more of the Earth because its orbit has a higher inclination at 51.6 degrees.
What is the most powerful telescope on Earth?
James Webb Space Telescope
, the world’s largest and most powerful space telescope, will be launched in 2021. The world’s largest and most powerful space telescope unfolded its giant golden mirror for the last time on Earth on Tuesday, a key milestone before the $10 billion (roughly Rs.
What are the disadvantages of putting telescopes in space?
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.
Which of the following 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.
Why do astronomers want telescopes in space?
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 is the most important factor to consider when purchasing a telescope?
The most important aspect of any telescope is
its aperture
, the diameter of its main optical component, which can be either a lens or a mirror. A scope’s aperture determines both its light-gathering ability (how bright the image appears) and its resolving power (how sharp the image appears).
What are the advantages of space based observatories?
Do not contend with the effects of Earth’s atmosphere, which include scattered light and
atmospheric absorption
, both of which reduce the flux measured from a NEO on the ground, and atmospheric emission, which can blind a telescope to a NEO in the infrared.
Why is a telescope in space better than one on 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.
What are 5 disadvantages of a refracting telescope?
- Very high initial cost relative to reflector.
- A certain amount of secondary spectrum (chromatic aberration) unavoidable (reflector completely free of this) The colours cannot focus at one point.
- Long focal ratios can mean that the instrument is cumbersome.
What are 2 problems with refracting telescopes?
The two problems with refracting telescopes are
a chromatic aberration and spherical aberration
.
What is the biggest advantage to having a telescope 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.
