Why have astronomers built the largest optical telescopes on the top of mountains?
To get above the thickest part of the Earth's atmosphere. The air absorbs light and its movements distort the image.
What else can I help you with?
Why do optical astronomers place telescopes at the top of mountains while radio astronomers put their telescopes in valleys?
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.
Are the largest telescopes optical telescopes?
No. Radio telescopes are the largest, consisting of multiple (sometimes hundreds) of dishes tens of metres across in enormous arrays.
Most optical telescopes used by professional astronomers are in?
Most optical telescopes used by professional astronomers are located on mountains or remote locations away from city lights to minimize light pollution and atmospheric disturbances. Some observatories, such as those in Chile and Hawaii, are known for having excellent observing conditions due to high altitudes and clear skies. Telescopes are also placed in space, like the Hubble Space Telescope, to avoid atmospheric interference.
Used by astronomers to study stars and planets?
Astronomers use telescopes to study stars and planets by capturing light from these celestial objects and analyzing it. They can gather data on the properties of stars and planets, such as their temperature, composition, and distance from Earth, to deepen our understanding of the universe. Telescopes come in various forms, such as optical telescopes, radio telescopes, and space telescopes like the Hubble Space Telescope.
How do astronomers study the very outer regions of the universe?
radio waves. Of course they also use very big optical telescopes.
What is an instrument used by astronomers to gather information aboutstars?
An optical telescope is commonly used, with radio telescopes used by the larger institutes.
How astronomy is related to technology?
All of the observational tools needed by astronomers: astrolabes, quadrant, clocks, sextants, octant, spectrographs, polarimeters, telescopes, optical mount, radio telescopes, space telescopes, etc. are products of various technologies.
What kinds of telescopes are used to see stars in visible light?
Refracting telescopes and reflecting telescopes are commonly used to observe stars in visible light. These telescopes utilize lenses or mirrors to gather and focus light, allowing astronomers to view stars with clarity and detail.
What three properties do optical telescopes have aid astronomers?
1) light-gethering power, 2) resolving power, and 3) magnifying power
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
How do astronomers try to improve the quality of ground based optical telescopes?
* By making them bigger.* By compensating for atmospheric disturbance, with something called adaptive optics.
What instrument to look at the sun?
Solar telescopes are used by professional astronomers both on earth and on satellites. These instruments differ from other optical telescopes because they do not need to collect light and also must deal with the heat from the object they focus on. The telescopes are very large.
