This is why in big cities only a few of the brightest stars can be seen in the night sky. advantage is that such telescopes are not encumbered by the Hubble Space Telescope Facts Hubble Space Telescope is about the size of a large school bus. Earth can be excavated by hand, transported in baskets and compacted with cattles walking over it. One plain example of an advantage of a telescope that is based on the Earth is the same advantage carried by all systems without remote components: If the telescope needs to be repaired or otherwise services, it can be done by human beings on the ground under normal conditions of gravity and oxygen. The main advantage of the Hubble Space Telescope is in it's name. This is not because such telescopes are materially closer to their objects of inquiry, but rather because the Earth's atmosphere can distort images so badly.

Astronomers began raising concerns about the potential for interference shortly after the launch of the first batch of 60 Starlink satellites in 2019. Even the invention of adaptive optics, a technique that reduces the effect of atmospheric interference on image quality, can't reproduce the image clarity of space telescopes. The first serious concepts of a space-based optical observatory began just after World War II. One such observatory is Chinas Xuntian space telescope, which is scheduled for launch as early as this year. To date, the telescope has studied more than 40,000 cosmic objects, providing views astronomers were unable to capture from the ground. In the mid-1960s, NASA and its contractors conducted phased studies into the feasibility of a large space telescope. 8 One way to sharpen up images from ground-based telescopes is to use a technique called adaptive optics or AO.

BY Nicholas Gordon. 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. 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. 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. NASA originally planned to launch in 1983, but the program experienced a considerable delay. Galaxies contain billions of stars.

Other NASA studies had also originally called for space telescopes, albeit using smaller mirrors that the 120-inch size proposed by the National Academy of Sciences. 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. Hubble has advantages over most telescopes when it comes to making detailed images of celestial objects like the Eagle Nebula. As a result, the angular resolution of space telescopes such as the Hubble Space Telescope is often much smaller than a ground-based telescope with a similar aperture.
