Why do observatories have dome that can opened and turned?
Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during observing, and closed when the telescope is not in use. In most cases, the entire upper portion of the telescope dome can be rotated to allow the instrument to observe different sections of the night sky. Radio telescopes usually do not have domes.
What do microwaves have to do with astronomy?
When examining the universe at optical wavelengths you tend to see bright spots (stars/galaxies) with huge expanses of black inbetween. However, at microwave wavelengths you see a background glow, known as the cosmic microwave background. This is a relic from the very early universe and can tell scientists a considerable amount about the early structure of the universe.
What is the use of telescope in ornithology?
Ornithological telescopes allow bird-watchers to observe birds from a distance, so there is less risk of frightening them away. Since they require a tripod, they are generally heavier to carry than binoculars, but binoculars are more difficult to use since they are more difficult to hold still and steady for any length of time. Also, telescopes are capable of greater magnification than binoculars.
What advantages do reflecting telescopes have over refracting telescopes?
refracting telescopes use lenses instead of mirrors. 1. chromatic aberration: when light passes through a lens it is focused at different points. Blue focuses closer to lens and red farther creating a smeared image. 2. Some light is absorbed by lenses. 3. Lenses are heavy and can only be supported by the edge. 4. Lenses must have to optically acceptable surfaces whereas a mirror only needs one.
Why did astronomers build optical telescopes on mountains?
so that optical astronomers can get a better view of the celestial objects. because as higher you ride from the ground the thinner the atmosphere layer, that are mainly responsible for the jiggling & distortion of the images taken by the optical telescopes..
Optical telescopes allow scientists to study what from objects in space?
Light
Why do astronomers continue to build even larger telescopes?
Radio telescopes allow us to see things that can't be seen in visible light. And vice versa, optical telescopes can show things that are not visible in radio telescopes. So, the information from both kinds of telescopes really complements each other.
How is a microscope an example of a technological design?
The design uses refraction of the objective lens to form an image. This image is then observed with a second lens to allow the eye to see it. Except for the types of lenses used the same principle is used in optical telescopes and binoculars.
Are black series telescopes a good telescope to buy for seeing different plantes?
Black series telescopes are good telescopes to buy for seeing different planets. They allow a clear view for stargazing.
What advantage do reflecting telescopes hAve over refracting telescopes?
One advantage of reflecting telescopes is that the mirrors can be very big. Large mirrors allow reflecting telescopes to gather more light than refracting telescopes do. Another advantage is that curved mirrors are polished on their curved side, which prevents light from entering the glass. Thus any flaws in the glass do not affect the light. A third advantage is that mirrors can focus all colors of light to the same focal point. Therefore, reflecting telescopes allow all colors of light from an object to be seen in focus at the same time.

Will New technologies allow astronomers to use X-ray telescopes on Earth's surface?
We had best hope the answer is 'no'. In order to use x-ray telescopes effectively from the earth's surface, you'd have to get rid of the atmosphere.
Can Earth-based telescopes can detect all forms of light?
No. Many frequencies of light are absorbed by the atmosphere, and so Earth-based telescopes can't detect it. That's why space telescopes such as the Hubble are so valuable; they allow us to see in frequencies that we cannot detect here on Earth.
Why would bigger telescopes allow us to discover more objects?

What is the bad side of Radio Telescopes?
They do not allow for visual observation. on the other hand they could monitor possible UFO radio traffic.
