How does adaptive optics in telescopes help solve problems caused by atmospheric turbulence?
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?
Astronomers can address issues with Earth-based telescopes by using adaptive optics to correct for atmospheric distortion, selecting observing sites at high altitudes or in deserts with stable air, and designing telescopes with larger mirrors to gather more light and improve image resolution. Additionally, they can employ techniques like interferometry to combine light from multiple telescopes for enhanced resolution.
What problems do astronomers have when looking through telescopes?
Astronomers may face challenges such as light pollution from surrounding urban areas, atmospheric turbulence which can distort images, and limited observation time due to weather conditions and the Earth's rotation. Additionally, technical issues with the telescope or instrumentation can also hinder observations.

How do astronomers solve problems using telescopes on earth?
Astronomers use telescopes on Earth to collect and analyze light from celestial objects, which allows them to study their properties, such as composition, distance, and motion. By employing various types of telescopes—optical, radio, and infrared—they can observe different wavelengths of light, revealing information that might not be visible to the naked eye. Advanced imaging and spectroscopy techniques enable astronomers to resolve complex problems, such as mapping star formation in galaxies or detecting exoplanets. Additionally, ground-based telescopes are often equipped with adaptive optics to compensate for atmospheric distortions, enhancing the clarity and detail of observations.
Why can the electromagnetic spectrum only be seen in space?
Due to the atmosphere and atmospheric pressure on the planet Earth the viewing of the Electromagnetic spectrum will or can be seen. It will be seen as a blur due to these atmospheric problems, hence the reason Nasa has puts telescopes in space and on high elevated places.
Are there any useful effects of refraction?

What kinds of problems occur with opticol telescopes?
Optical telescopes are of two types: refractive and reflective. The refractive telescopes have chromatic aberration (huh? different colors are focused in different plains -- huh?). This is less of a problem with reflective telescopes.
Why are most large telescopes reflecting telescopes?
They are refracting telescopes(:Large refracting telescopes are no longer built because there were too many problems with them. There was color distortion, light pollution, and when the object hits the focal point it turns upside down. Then you don't see the object for what it really is, you see it upside down and weird-ed out. They are to complicated and scientists believed they should just stick with the simple, small, original refracting telescopes!!!!-Meghan Betts (8th grader)
