This result explains a previous finding that this galaxy is missing most of its dark matter. Lacking essential data, scientists were unable to extrapolate information such as the age of the universe, the birth of stars, the existence of black holes and dark matter until the advent of space telescopes. Why telescopes in space have an advantage in terms of effective collecting area and effective resolving power over ground based telescopes? It points to the potential of the space program Although the Hubble Space Telescope is not without its disadvantages, the fact of the matter is that it has been more successful than not. What is one big advantage that the Hubble Space Telescope have over Earth-based telescopes? Optimal ground telescope operation requires low temperature and pressure conditions, but instruments in space don't require environmental stability because space is devoid of large fluctuations in lighting, temperature and pressure. Private companies are . . Scientists and engineers must take different physical factors into consideration when finding a suitable location to place a ground-based telescope. 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. In addition to blurring images, the Earths atmosphere also absorbs significant portions of the light, or electromagnetic, spectrum. example. There is no distortion due to twinkling, glow from the sky or the effects of light pollution. The year 1983 did have its own notable events however, with the founding of the Space Telescope Science Institute at the John Hopkins University in Maryland. What are the advantages of a ground-based telescope? Starlink will connect previously disconnected communities all over the world. The problem is, Hubbles orbit is decaying but good news, there is a solution.. Clearly, though, not all telescopes can be dispatched to space and operated remotely. Columbia crewmembers installed the new Advanced Camera for Surveys (ACS), which had sharper vision, a wider field of view, and quicker data gathering than the Wide Field/Planetary Camera 2.

With a ground based telescope, the light that Although there was initial dissent within NASA over whether the agency should work its way up to a large-scale observatory or take one giant leap to the final product, the decision to develop the Space Shuttle program greatly improved the flexibility NASA would have in designing a space telescope. In the mid-1960s, NASA and its contractors conducted phased studies into the feasibility of a large space telescope. In terms of being able to make detailed observations, you are going to find that the atmosphere causes a lot of problems, particularly in terms of murkiness. Some are used to study a special object like the Sun. the telescope is looking at must travel through our atmosphere 2 What is not an advantage of the Hubble Space Telescope?

In contrast, space telescopes like the Hubble aren't hindered by the atmosphere and thus produce clearer images. Most other advantages of Earth telescopes also revolve around the notion of convenience (or avoiding extreme inconvenience). There are actually several advantages: No bad weather, no day and night: Even the best observing sites on Earth suffer from occasional rain and cloud. This is a problem because the atmosphere can blur our images. Clearer observations can be taken as the atmosphere does not affect it. Although the Hubble Space Telescope has been in orbit since 1990, its origins date long before that. 3. What is the advantage of the telescope? His paper, entitled, While teaching at Princeton University, Spitzer was asked to head a National Academy of Science Ad Hoc Committee on the Large Space Telescope. To date, the telescope has studied more than 40,000 cosmic objects, providing views astronomers were unable to capture from the ground. Analytical cookies are used to understand how visitors interact with the website.

Unfortunately for the program, the large space telescope's total cost was roughly estimated at $400 to $500 million, making it a tough sell. Overall, the researchers found that 2.7% of the individual Hubble exposures with a typical exposure time of 11 minutes were crossed by satellite trails, and that the percentage is increasing with time. STS-103 astronauts also replaced one of the telescope's three fine guidance sensors and installed a new computer, all in time to redeploy Hubble into orbit on Christmas Day. Easy Handling of Earth.
