To get better images with large telescope mirrors. it is necessary to counteract the distortions caused by the atmosphere and gravitational/thermal stresses.
* By making them bigger.* By compensating for atmospheric disturbance, with something called adaptive optics.
It uses lasers or sunlight or in some circumstances moonlight. That causing reflection.
Adaptive optics which change the shape of large mirrors during observation have helped to reduce atmospheric distortion.
A large aperture telescope that does not have adaptive optics which can compensate for unevenness in the atmosphere.

adaptive optics, It's a lot easier for a computer to constantly monitor and change the shape of multiple thin mirrors than it is to use a telescope with a large thick mirror that has to thermally adjust before being able to focus sharply, and even then, a large mirror or lens can't compensate for air turbulence the way a telescope with computer controlled adaptive optics can.

The Earth's atmosphere carries with it pollutants and water vapor that tend to attenuate incoming light from space and reflect light back to Earth emanating from ground sources. The atmosphere can act as an unrefined lens that can distort images due to its inhomogeneous density. Interference between light and various gasses in the atmosphere may act to distort the wavelength of incoming starlight. To put a telescope into space allows one to eliminate these difficulties by removing the atmosphere from the observations. I do not know of adaptive optics specifically but I would take it that adaptive optics would allow for refinement and correction for atmospheric interferences when observations are made on Earth by mathematical methods.
Optics is the study of light.

Yes, culture is adaptive.
all the adaptive features of a goat!
Primarily:Turbulence in the earth's atmosphere which creates twinklingMaybe also:Gravitational stresses due to tilting a telescopeThermal deformations caused by uneven heating/cooling of a telescope mirror
