Where are ground telescopes best located?
For optical telescopes, most ground-based observatories are located far from major centers of population, to avoid the effects of light pollution. The ideal locations for modern observatories are sites that have dark skies, a large percentage of clear nights per year, dry air, and are at high elevations.
How far can ground based telescopes see?
The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.
What are the two major reasons for placing telescopes in satellites?
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.
What is the difference between refracting and reflecting telescopes?
Reflecting telescopes use mirrors to gather the light. Refracting telescopes use lenses. There are different kinds of reflectors, but in general the refractors all follow the same basic design.
What are the advantages and disadvantages of putting a telescope in space?
8 Advantages and Disadvantages of Hubble Space Telescope
- The earth’s atmosphere. The first advantage?
- The detail is absolutely extraordinary. When you can eliminate the atmosphere, you have a degree of clarity that is still largely unmatched.
- It points to the potential of the space program.
- Operating in space.
- Time consuming.
- Expensive.
- Repairs are difficult.
- Out of date.
