Scintillation. Our atmosphere is in continous motion. Warm air changes the angle of EM waves passing through a little bit differently than cold air. The constant motion causes constant shifts in the waves. This is why the stars seem to twinkle. In space, there is no such distortion. Space borne telecopes see far clearer images because of this.

Why are some telescopes placed in space above the earths atmosphere?

Some telescopes are placed in space to avoid the Earth's atmosphere, which can distort and absorb light from celestial objects. Atmospheric interference can blur images and limit the wavelengths of light that reach the ground. By positioning telescopes in space, astronomers can obtain clearer, more detailed observations across a broader range of wavelengths, including ultraviolet and infrared, which are blocked by the atmosphere. This enables more accurate studies of the universe and its phenomena.


What instrument can view the heavenly bodies clearly and without the filtering effect of the earths atmosphere?

A space telescope such as the Hubble Space Telescope can view heavenly bodies clearly without the filtering effect of Earth's atmosphere. These telescopes orbit above Earth's atmosphere, providing a clear view of objects in space without distortion or interference.


What causes the pressure of the atmosphere?

Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.


What is free atmosphere?

The free atmosphere refers to the layer of the Earth's atmosphere above the planetary boundary layer where air moves freely and is not influenced by the Earth's surface. It is typically above the lowest few kilometers of the atmosphere and is important for understanding atmospheric processes on a larger scale.


Does the earths atmosphere extend about 1 kilometer above its surface?

No, the Earth's atmosphere extends much higher than 1 kilometer above its surface. The exosphere, the outermost layer of the atmosphere, extends up to 10,000 kilometers above the Earth's surface.

Why would an X-ray telescope based on Earth not be able to detect X-Rays emitted distant stars?

Earth's atmosphere absorbs and scatters X-rays, preventing them from reaching the surface. To detect X-rays from distant stars, X-ray telescopes need to be placed in space above the atmosphere. This allows them to collect and study X-rays without interference.


Why do some telescopes that collect electromagnetic radiation in the shorter wavelengths need to be placed either in dry areas or outside the atmosphere?

Telescopes that collect electromagnetic radiation in shorter wavelengths, such as ultraviolet or X-rays, need to be placed in dry areas or outside the atmosphere because water vapor and other gases in the atmosphere can absorb or scatter such high-energy radiation, affecting the observations. Placing these telescopes in dry areas or above the atmosphere helps ensure that they can collect unimpeded data in these wavelengths.


Why are some telescopes placed above earths atmosphere?

They're at high elevation - to escape the atmospheric disturbance caused by natural and man-made heat 'currents'. Shifting heat currents cause images collected by telescopes to distort. Placing them at higher altitudes minimises the effect, so the images are clearer. Additionally, being high up, they're away from towns and cities, which vastly reduces the amount of 'light pollution' created by man-made light sources.


Why are near infrared telescopes located on mountaintops and ultraviolet telescopes in Earth orbit?

Mountaintops are ideal for near-infrared telescopes because the high altitude reduces atmospheric interference and light pollution. Ultraviolet telescopes are placed in Earth orbit to avoid absorption of ultraviolet light by Earth's atmosphere, which allows for clearer observations of objects emitting in the ultraviolet spectrum.


What layer of the earths atmosphere extends 17km above the earth?

stratosphere

Why is it important that the projectile in the last question be above the Earths atmosphere?

because of Air Ressistant


Why are astronomical IR telescopes deployed well above the cloud but never on the ground?

Ground based telescopes are not as effective at these observations because infrared light is largely blocked by water in Earth's atmosphere.


What is the air above the earths surface called?

The layer of air above the Earth's surface is called the atmosphere. It is composed of various gases and extends several kilometers into space.
