Why does the Hubble Space Telescope give clearer images than those from earth?
Hubble does not have to contend with the atmosphere of the earth which bends and distorts images from earth-based telescopes.
How Is The Hubble Tescope Used?
The Hubble Telescope is a freely moving object sent into space by NASA to take pictures and make observations in space, especially in areas not easily accessible with telescopes. There are more than one Hubble Telescope, such as those in deep space versus ones that are fairly close.
Is space travel real or fake?
It's both. Travel by humans to anywhere further away than the Moon is, so far, "fake" (or at best speculative). However, the Apollo manned Moon missions were real, as are low Earth orbit missions like those to the International Space Station and the Hubble Telescope.
What are the special instruments used in studying the sky?
Generally telescopes. These can vary from small affairs you set up in the garden to study the sky, to those actually in the sky as with the Hubble Space Telescope. There are also many dotted around in observatories.
Why does the hubble space telescope produce clearer images than those on earth?
Because the atmosphere is not exactly transparent. It looks that way to us because our eyes are designed to see the wavelengths that move easiest through it. However, air molecules tend to warp, absorb, or otherwise limit our ability to see things in space clearly. The Hubble, and other space-based telescopes, are above the limiting influence of our atmosphere, and as such can see the light from distant objects exactly as they arrive.

Which technology can allow a single ground-based telescope to achieve images as sharp as those from the Hubble Space Telescope?
adaptive optics

Who can use the hubble telescope?
Astronomers, mostly those who work for NASA. Some astronomers from Universities can also access it.
Why was the hubble space telescope sent to space?
The Hubble Space Telescope (HST) was launched into space to allow it to view the heavens without the distortion of images caused by looking through the atmosphere itself, the degradation of images caused by the dust in the atmosphere, and the interference caused by ambient light on the surface of the earth. All those problems can be partially overcome by a careful selection of a location for a telescope on earth, but putting the telescope in space completely eliminates all of them, except space dust.The improvement of the image quality allowed astronomers to look at small objects relatively close to Hubble, or huge objects much farther away.For example Hubble was used to study the dwarf planets in our solar system Pluto and Eris.Hubble was also used to study galaxies BILLIONS of light years away. A light year is a measure of distance. It is the distance light travels in one year. Light travels 5,860,000,000,000 miles in one year, so Hubble can see galaxy sized objects billions of times a light year away.The distance, however, is not the important part of that statement. The important part of the statement "billions of light years away" is "billions of years". Because Hubble can see so far it is, in fact, showing something NOW that happened billions of years ago. That is because the light had to travel for billions of years to reach Hubble. It is allowing astronomers and scientists to observe the universe as it was billions of years ago. This is producing a multitude of theories and scientific papers.that pretty much covered everything i said except that hubble was last luanched to get to the begginning of time, it's a big gamble for sientists...i don't even have to write more now :P

What type of telescope is the famous telescope that orbits the earth?
Telescopes that work with light and radio waves can work from Earth´s surface. Any other types of electromagnetic waves will hardly reach Earth's surface, so to use those (e.g., X-rays, infrared, and others), telescopes have to be taken to outer space.
The Hubble Space Telescope orbits Earth and sends images of distant objects. Why does Hubble form better images than the optical telescopes used on land?
Because it works with pure, fresh, clean light, and not the stuffthat has been dragged through several miles of air first.By the way ... there's only one single Hubble Space Telescope. OnApril 24, 2014, it'll polish off a cool 24 years operating in Earth orbit !
What is the name of the large spiral galaxy found in the bottom right of the Hubble Deep Field?
The point of the Hubble Deep Field observations is that scientists pointed the Hubble Space Telescope toward a dark patch of the sky where there were no known stars or galaxies. Everything observed in those photos had been entirely unknown before the images were obtained. So, nothing there has a "name"; by now, it probably has an index number in some database. But not a "name".

Why does the hubble telescope works better in space than on the earths surface?
We have an atmosphere that gets in the way. Pockets of air at different temperatures and different volumes act as lenses, just like those in the telescope itself, that bend the light and can do so rapidly. In fact, this bending of light is the cause of most UFO sightings. Given the properties of light, this bending can cause a change in shape and color of the object being observed and so can cause a lot of problems with useful data. Placing the telescope above the atmosphere (or in its uppermost reaches) allows the observer to bypass these issues.
