SOLAR SYSTEM

Detailed explanation-1: -Since 1990, the Hubble Space Telescope has been orbiting Earth and sending back images of space for astronomers to view and interpret. What benefit is there to a telescope that orbits Earth? Views from outer space telescopes are clearer than those from Earth-based telescopes.

Detailed explanation-2: -The Hubble Space Telescope is a large telescope in space. It was launched into orbit by space shuttle Discovery on April 24, 1990. Hubble orbits about 535 kilometers (332 miles) above Earth. It is the length of a large school bus and weighs as much as two adult elephants.

Detailed explanation-3: -Scientists have used Hubble to observe the most distant stars and galaxies as well as the planets in our solar system. Hubble’s launch and deployment in April 1990 marked the most significant advance in astronomy since Galileo’s telescope.

Detailed explanation-4: -Hubble has provided evidence of an accelerating universe Astronomers use these massive explosions to measure distances to far-off galaxies, and have found that the expansion of the universe is accelerating. The cause of this mysterious acceleration has been dubbed “dark energy."

Detailed explanation-5: -Hubble was designed as a general purpose observatory, meant to explore the universe in visible, ultraviolet and infrared wavelengths. To date, the telescope has studied more than 40, 000 cosmic objects, providing views astronomers were unable to capture from the ground.

Detailed explanation-6: -The Hubble telescope provides four key advantages over most other optical astronomical facilities: unprecedented angular resolution over a large field, spectral coverage from the near infrared to the far ultraviolet, an extremely dark sky, and highly stable images that enable precision photometry.
