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. Hubble orbits above Earths atmosphere, which gives it a better view of the universe than telescopes have at ground level. The atmosphere causes the apparent twinkling effect of stars, although stars don't actually twinkle in space. 4 What are three advantages of using a space based telescope such as Hubble over land based telescopes? In order to move from concept to reality, the telescope needed support from NASA, the only agency likely to be able to execute the National Academy's recommendation. B) Telescopes can collect far more light with far greater magnification. No light pollution Light pollution is the effect city lights have on the sky, making it brighter and therefore making it more difficult to look at the stars. The earths atmosphere The first advantage? What are telescopes used for? Born in 1889, Hubble discovered that many objects previously thought to be clouds of dust and gas and classified as nebulae were actually galaxies beyond the Milky Way. Theyre also able to detect frequencies and wavelengths across the entire electromagnetic spectrum. The Perkin-Elmer mirror was completed in 1981, but the entire optical assembly was not put together until 1984. (Courtesy of Analytical Graphics, Inc.) Figure 4.1.1-4.

Necessary cookies are absolutely essential for the website to function properly. Another disadvantage for ground-basedtelescopes is that the Earths atmosphere absorbs much of the infrared andultraviolet light that passes through it. Clearer observations can be taken as the atmosphere does not affect it. In addition, there are many wavelengths from the electromagnetic spectrum that do not reach Earth because they are absorbed or reflected by the Earth's atmosphere. or reset password. The most recent servicing mission to the spacecraft, servicing mission 3B, came aboard STS-109 in March, 2002. This is why such telescopes are often built at very high altitudes if possible, such as the Mauna Loa Observatory in Hawaii. Shattered comets and misshapen asteroids. I primarily work with TESS transit data and Hubble Space Telescope exoplanet transmission spectroscopy data, and I'm also interested in enabling more collaborative science with open source astronomical software tools.

And Hubble has helped scientists learn more about explosions that happen when huge stars burn out. 4 Why was the telescope such an advancement for the study of space? One major advantage is that it does not have to contend with the distortion of light caused by the atmosphere. Space telescopes can detect thesewaves. These optical instruments eventually evolved into the gigantic telescopes sitting in observatories at the apexes of mountains and volcanoes such as Mauna Kea in Hawaii. Astronomers using Hubble data have published more than 15,000 scientific papers, making it one of the most productive scientific instruments ever built. Time consuming Regardless of the work that needs to be done with the Hubble Space Telescope, you can count on a long wait. 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. 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.
