You will be able to capture detail in a truly impressive fashion. 4 What are the disadvantages of Earth based telescopes? Telescopes that capture infra-red rays, x-rays and gamma rays, which cannot be seen but are very important in physics, have to be in space because the atmosphere occludes them completely. Having telescopes on Earth that allowed people to look at the relatively distant heavens was one of the most transforming (and controversial) developments in human history.

The Perkin-Elmer mirror was completed in 1981, but the entire optical assembly was not put together until 1984. In space, however, telescopes are able to geta clearer shot of everything from exploding stars to other galaxies. 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. 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.

Practically speaking, they also have a much lower risk of being damaged by one of the 500,000 pieces of debris flying through the cosmosor space junk. To date, the telescope has studied more than 40,000 cosmic objects, providing views astronomers were unable to capture from the ground. For what its worth, SpaceX and NASA are looking into the possibility of reboosting Hubble to a more sustainable orbit, in collaboration with a privately funded space effort called the Polaris Program. This is due to not only the lengthy wait, owing to the distance, but it is also due to the challenges of working in space.
