Early telescopes showed that Earth was not the center of the universe, as was previously believed. Not always, really there are many different trade offs in costs.. for one, you cannot launch as huge a telescope in space as you can build here on Earth. Space telescopes can detect these waves. Hubble does have the advantage of being a narrow field-of-view observatory, according to McDowell, meaning it's focusing on relatively small swaths of the sky at one time, making it easier to avoid satellite crossings. Telescopes operating at this wavelength must be cooled to observe faint astronomical objects. This is a problem because the atmosphere can blur our images. Webb will have significantly larger field of view than the NICMOS camera on Hubble (covering more than ~15 times the area) and significantly better spatial resolution than is available with the infrared Spitzer Space Telescope. The man advantages of today's Earth-based telescopes are fairly obvious bigger and better lenses and means of manufacturing them, for example but the ways in which Earth-based telescopes are still superior to their "overhead" counterparts cannot be ignored, either. Yet the Hubble Space Telescope has done just that. 7 Why are space-based telescopes better than land-based telescope? The space telescope will also use gravitational lensing techniques to conduct massive exoplanet surveys, possibly discovering many more planets outside our solar system than even the Kepler. 3. It points to the potential of the space program. One plain example of an advantage of a telescope that is based on the Earth is the same advantage carried by all systems without remote components: If the telescope needs to be repaired or otherwise services, it can be done by human beings on the ground under normal conditions of gravity and oxygen. This is why such telescopes are often built at very high altitudes if possible, such as the Mauna Loa Observatory in Hawaii.
