B) Telescopes can collect far more light with far greater magnification. Final Results from theHubble Space TelescopeKey Project to Measure the Hubble Constant . What is the advantage of putting a telescope in space instead of on earth? But Hubble's future would be in limbo once again, when tragedy struck on January 28, 1986. Clearer observations can be taken as the atmosphere does not affect it. Telescopes have also helped us understand gravity and other fundamental laws of the physical world. What Makes Hubble Different From Telescopes on Earth? While this distortion still allowed scientists to study the cosmos and make significant discoveries, it resulted in less spectacular images, and some of the original mission could not be fulfilled. Disadvantages and limitations of Earth based optical telescopes They can only be used at night. Earths atmosphere changes and blocks some of the light that comes from space. The Hubble Telescope was a worldwide phenomenon even before it was launched into space, so anticipated was its ability to capture dazzling imagery from miles above Earth, where its optical apparatus would be unencumbered by the distorting effects of the Earth's atmosphere. Which is cheaper a Space Telescope or a ground-based telescope? or reset password. The first advantage? 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. 1703-1727) is the inventor of the reflecting telescope, having conceptualized the notion in 1666*. name.
