How adaptive optics in a telescope help solve problems caused by atmospheric turbulence?
Wiki User
∙ 14y ago
The atmosphere is a chaotic mixture of gases and vapours. The turbulences in the atmosphere distort the paths of light-rays falling on the Earth from distant celestial objects, thereby distorting the images they form in telescopes.
To compensate, the more advanced modern telescopes use lasers to measure the current distortion in the atmosphere directly in the path of the telescope, and use those measurements to change the shape of the mirror in the telescope from millisecond to millisecond, thereby cancelling much of those distortions.

How do astronomers solve the problems with earth based telescopes?
Adaptive optics which change the shape of large mirrors during observation have helped to reduce atmospheric distortion.

What type of telescope minimizes color focus problems?
A telescope with achromatic lenses.
What problems did making the telescope make?
The telescope helped us by showing us what we can't see with our eyes

What problems have there been with the hubble telescope?
the mirror was not right
Did the hubble space telescope have any problems?
yes
How is the hubble telescope getting fixed?
when there are problems with the hubble space telescope, astronomers send astronauts to go fix the problem.
Explain two reasons for sending telescopes into space?
Astronomers have several reasons to send telescopes into space, including: * The atmosphere makes stars look blurry. the simple answer is the atmosphere. The layers of air in the atmosphere may seem clear but contribute to a fuzzy picture in space. To avoid this they send telescopes into space where nothing is in between the telescope and the observed object. One reason for sending telescopes into space is so that people can get a better look at the stars the second reason for this is so that scientist can discover more about stars. * The atmosphere completely blocks some kinds of light -- in particular, ultraviolet and far-infrared light. On earth, spectrometers using this kind of light tell us a lot about local materials. To get the same information about stars and planets, we need to put the spectrometer outside the veil of the atmosphere. People who are not astronomers have other reasons to send telescopes into space, including * Telescopes on "weather satellites" and "spy satellites" pointed at earth can get photos and accurate maps of places and weather that are extremely difficult to get in any other way.
What problems did the Hubble space telescope face when it was in space?
launch delays, budget problems and a incorrect mirror
