Astronomy EOY Review

The Hubble Space Telescope, one of mankinds greatest advances in understanding space, was launch in 1990. Hubble is a space-telescope that orbits Earth above the atmosphere. How can a space-telescope such as Hubble provide more valuable data than a traditional ground-telescopes used by astronomers?

• closer to objects in space

• more expensive and better technology

• atmosphere distorts and blocks the light

• secret technology not used in ground-telescopes
