The Hubble Space Telescope, known for recording awe-inspiring images of the cosmos while advancing the field of astronomy, is under threat. 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. 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. The costliness of a space telescope such as the Hubble telescope includes the cost of materials, labor and launching it into space. Ground-based observatories took the reins, providing the historic first burst of exoplanet discovery. 4 Why was the telescope such an advancement for the study of space?

In addition to demonstrating conclusively that the Earth and the other planets revolve around the sun, and that the solar system in turn spins around the center of the Milky Way galaxy, ground-based telescopes have bolstered human knowledge about distant objects as the telescopes have become more powerful. A mirror reduction from 3 to 2.4 meters helped bring the project down to about $200 million, approximately half the originally expected price tag. The Hubble Space Telescope keeps getting photobombed, and it's just going to get worse. It's 14 meters long, again not freaking huge. Why is Hubble able to see so much better than telescopes on Earth? Which is cheaper a Space Telescope or a ground-based telescope? It does not store any personal data. Hubble allows us to see objects more clearly because it is above the clouds in Earth's atmosphere. For optical telescopes such as the ones being discussed, the only real advantage of putting a telescope in space is that it can do its job much better there.
