Some objects emit only radio waves or only X-rays. This is why it is important to study the Universe with various kinds of space observatories. … By collecting gamma rays, astronomers are able to see these violent events and can judge exactly how they shape the Universe.

Why do astronomy scientist use observatories?
Astronomers can improve their chances of a good image by putting observatories on mountain-tops (above some of the atmosphere), but there will still be limits to how crisp their images will be, especially for faint sources. Visible-light observatories in space avoid the turbulence of the Earth’s atmosphere.
Why are astronomers interested in building observatories capable of detecting?
Why are astronomers interested in building observatories capable of detecting neutrinos, cosmic rays, and gravitational waves? These things are not forms of light, and therefore can provide different types of information than light about objects that emit them. … Observatory X consists of a single 50-meter telescope.
How are observatories used by astronomers?
Space-based observatories
Space telescopes can be used to observe astronomical objects at wavelengths of the electromagnetic spectrum that cannot penetrate the Earth’s atmosphere and are thus impossible to observe using ground-based telescopes.
What were the observatories used for?
Observatories are used to make observations in the radio, infrared and visible light (optical) regions of the electromagnetic spectrum. Most telescopes are put into domes to protect their instruments from poor weather.
Where is the best place to put a telescope on Earth?
Astronomers now have a new potential location to try to avoid the twinkling. Only one problem though: it’s really cold, especially this time of year. A team of astronomers from Canada, China, and Australia have identified a part of Antarctica as the ideal place to put observational telescopes.
What is the old name of observatory?
The Madras Observatory was an astronomical observatory which had its origins in a private observatory set up by William Petrie in 1786 and later moved and managed by the British East India Company from 1792 in Madras (now known as Chennai).
What is the ideal way if cost is no object?
The problems encountered with lenses caused this scientist to build reflecting telescopes of his own design. Nearly all large optical telescopes built today are ________. What is the ideal way, if cost is no object, for a telescope to avoid atmospheric disturbance? Place it in space.
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.
Which of the following is the most important reason for putting 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. Most of the time this is a good thing.
How many space observatories are there?
There are over 350 professional observatories operating in the United States.
Why are observatories so important?
Why are space observatories important? The answer concerns twinkling stars in the night sky. To reach telescopes on Earth, light from distant objects has to penetrate Earth’s atmosphere. … Observatories located in space collect data free from the distortion of Earth’s atmosphere.
What is the largest telescope in the world?
The largest visible-light telescope currently in operation is at Gran Canarias Observatory, and features a 10.4-meter (34-foot) primary mirror. The Hobby-Eberly Telescope at McDonald Observatory near Fort Davis, Texas, has the world’s largest telescope mirror.
What are some disadvantages of observatories?
- 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.
How do we observe space?
Space telescopes
Objects in the universe emit other electromagnetic radiation such as infrared, X-rays and gamma rays. These are all blocked by the Earth’s atmosphere, but can be detected by telescopes placed in orbit round the Earth. Telescopes in space can observe the whole sky and can operate both night and day.
How do scientists observe space?
Things in space which release or reflect light, like stars or planets, can be seen either with the naked eye or with telescopes. By looking at that light, scientists can either directly tell where objects in space are, or at least can make deductions about their locations.
