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. The Hubble telescope provides four key advantages over most other optical astronomical facilities: unprecedented angular resolution over a large field, spectral coverage from the near infrared to the far ultraviolet, an extremely dark sky, and highly stable images that enable precision photometry. Telescopes are placed into orbit around the Earth or are sent farther out into space to get a clearer view of the Universe. The first advantage? Can the Constitution be changed by the president? These observations allow us to characterize the galactic and local environ What are the pros and cons of space telescopes? 4 min read. The Hubble Space Telescope (HST) has several advantages over telescopes on the ground. Others are used to study the different types of light given off by objects in space.

Even the invention of adaptive optics, a technique that reduces the effect of atmospheric interference on image quality, can't reproduce the image clarity of space telescopes. In space, however, telescopes are able to get a clearer shot of everything from exploding stars to other galaxies. These streaks are readily removed using standard data reduction techniques, and the majority of affected images are still usable, The New York Times quoted a NASA spokesperson as saying. But as more satellites are launched, the issue could become more pressing, for Hubble and other space telescopes. Funding for the telescope was originally denied by the House Appropriations Subcommittee in 1975, but this prompted a large-scale lobbying effort by NASA and leading astronomers, led by Spitzer and John Bahcall, another Princeton astronomer who was also an original proponent of the telescope. Scientists and engineers must take different physical factors into consideration when finding a suitable location to place a ground-based telescope. Ground-based telescopes cost about 10 to 20 times less than a comparable space telescope.

Earth's atmosphere obscures our view of space, so we put satellites, like the Hubble Space Telescope, above the atmosphere to see better. Theyre easier to maintain and upgrade. Ho-Diep Dinh has been writing since 2005. In contrast, NASAs James Webb Space Telescope would be unaffected, because its far beyond Earth-orbiting satellites. Operating in space Not surprisingly, operating a telescope that is in outer space can be a hassle. In February, 1997, the crew of STS-82 installed the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) and the Space Telescope Imaging Spectograph (STIS) to detect infrared light from deep-space objects and take detailed photos of celestial objects.

Telescopes on the ground may be cheaper, but Hubble - The Conversation Final Results from theHubble Space TelescopeKey Project to Measure the Hubble Constant . 2 What is not an advantage of the Hubble Space Telescope? Hubble allows us to see objects more clearly because it is above the clouds in Earth's atmosphere. Ground-based observatories have an advantage here over space-based ones because they can enjoy a much greater field of view. Satellites in low Earth orbit (LEO) spin around Earth once every 90 minutes. Some are used to study a special object like the Sun. Because of the protective effect of the atmosphere, ground-based telescopes can't pick up the lethal, invisible portions of the electromagnetic spectrum such as ultraviolet rays, x-rays and gamma rays.
