One advantage the HST has over ground-based telescopes is that there is no atmosphere through which the telescope must look to gather its data. Early telescopes showed that Earth was not the center of the universe, as was previously believed. The technology got better and the planet count ran into the hundreds. Earth's stratospheric ozone layer blocks all wavelengths shorter than 300 nm from . Is Taco Bell healthier than other fast food? The Hubble Space Telescope keeps getting photobombed, and it's just going to get worse. You will be able to capture detail in a truly impressive fashion. The main advantage of the HST is the increased amount of nighttime viewing it affords (T/F) F The term "seeing" is used to describe how faint an object can be detected by a telescope (T/F) F One of the primary advantages of CCD's over photographic plates is the formers high efficiency in detecting light (T/F) T 4 min read. telescope on a windy day is much worse than on a calm day for The air also blocks out light from parts of the electromagnetic spectrum. Because of much less base width, the problems of uplift pressure are minor. Clearer observations can be taken as the atmosphere does not affect it. But the trend line suggests that more and more satellites will cause more and more interference. Most telescopes used by astronomers are on Earth. The Europeans were mainly responsible for the solar array that would power Hubble while in orbit. However, all these advantages do come with a price. They can be built bigger and for less money. 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. Some are used to study a special object like the Sun. Advantages and Disadvantages of an Astronomical Telescope. Taking multiple exposures of the same spot and adding them work on Earth as well as in space -- most of the sky is occulted by the Earth at some point int he Hubble's orbit. If someone fails to see the need for a space program, someone else could point to the numerous successes of the Hubble Space Telescope. Analytical cookies are used to understand how visitors interact with the website. D) Telescopes collect more light and are unaffected by twinkling. Telescopes have also helped us understand the light that radiates from the sun and other stars. Advantages. During the EVAs, COSTAR was installed and the Wide Field/Planetary Camera was replaced with the Wide Field/Planetary Camera 2, which was designed to compensate for the mirror problem.

As mentioned before, the Hubble Space Telescope is not without its problems. Subsequent final assembly of the spacecraft did not take place until 1985. In contrast, space telescopes like the Hubble aren't hindered by the atmosphere and thus produce clearer images. The cookie is used to store the user consent for the cookies in the category "Performance". Scientists and amateur astronomers have had time to work out the pros and cons of ground-based telescopes for several centuries now. Why is Hubble able to see so much better than telescopes on Earth? Scientists note that Earth telescopes are not at risk of being damaged by flying space debris, for obvious reasons. There are advantages of space telescopes and there are advantages of Earth-based telescopes; which you use depends on your means, your goals and your general interests. Earths atmosphere changes and blocks some of the light that comes from space. While visible light can be observed from the ground, ultraviolet light can be easily observed only from space. This ties into the point mentioned above. 1703-1727) is the inventor of the reflecting telescope, having conceptualized the notion in 1666*. This cookie is set by GDPR Cookie Consent plugin. A picture called Hubble Ultra Deep Field shows some of the farthest galaxies ever seen. Ground-based telescopes can't do the same, because the Earth's atmosphere absorbs a lot of the infrared and ultraviolet light that passes through it. This is why in big cities only a few of the brightest stars can be seen in the night sky. However, you may visit "Cookie Settings" to provide a controlled consent. Astronomers and scientists have even placed their creations out in space to complement the data provided by their Earth-based telescopes. Why is the Hubble Space Telescope so important?
