That means that the telescope is on planet Earth, as opposed to a planet in outer space, like the Hubble Telescope, the Planck Telescope, the Chandra Telescope, etc.
It is a telescope based on our earth
The Hubble Space Telescope is a space-based observatory launched by NASA in 1990. It orbits Earth and captures high-resolution images of celestial objects in visible, ultraviolet, and infrared light. Hubble has greatly contributed to our understanding of the universe and made countless scientific discoveries.
No. The Hubble Space Telescope was built on Earth and launched into space. It is about the size of a bus.
The Hubble Telescope is a space telescope which is approximately 559 kilometers away from the surface of the earth in a "low earth orbit" which indicates that it is orbiting under 200 kilometers.
No, the Hubble Space Telescope is not bigger than the Earth. The Earth has a much larger diameter (approximately 12,742 kilometers) compared to the Hubble Space Telescope, which is about 13.2 meters long and 4.2 meters wide.
Hubble does not have to contend with the atmosphere of the earth which bends and distorts images from earth-based telescopes. http://wiki.answers.com/Q/Why_does_the_Hubble_Space_Telescope_give_clearer_images_than_those_from_earth

Atmospheric and environmental interference.
An earth-based telescope has to contend with atmospheric turbulence, which can distort and blur images. This is not a concern for a space-based telescope, which operates above Earth's atmosphere and can provide clearer images.
not affected by earth's atmosphere
The Hubble is in orbit around planet earth.
The main advantage would be the absence of an atmosphere. Any telescope on earth can only "see" electromagnetic (light) waves after they have travelled through the atmosphere, losing some of their directional integrity, which distorts the image seen in earth bound telescopes. Some light waves never make it to the telescope at all.
A space telescope produces clearer images because it is above Earth's atmosphere, which can distort and blur light from space. By being in space, the telescope eliminates the atmospheric turbulence that can affect the quality of images produced by Earth-based telescopes. This allows space telescopes to capture sharper and more detailed images of celestial objects.
I think that a land-based telescope has the atmosphere as an obstacle for good observations, while the space telescope hasn't, so the images taken are more defined. Moreover, the earth orbit of the space telescope allows it to get a wide range of angles. Text by Jim West70
The telescope in orbit around the earth as of 2010 is the Hubble Telescope.
It does not have the interference caused by the earth's atmosphere to see through, so it can make a better quality image.
A land-based telescope is a telescope that is located on Earth's surface, as opposed to being placed in space or on an airborne platform. These telescopes are typically situated at observatories and are used to study celestial objects and phenomena from the ground.
There is no distortion from Earth's atmosphere.
