Hubble Space Telescope:

Known as Hubble, this telescope was sent into Earth’s orbit in 1990. It is named after the asronomer Edwin Hubble. It is one of the largest and most versatile, and well known as both a vital research tool and a public relations boon for astronomy.

Hubble’s Involvement with Space Research:

Hubble is one of the most famous names when it comes to space research and astronomy because of his work in the following fields:

1. Redshift- redshift increases with distance
2. Discovery of the asteroid 1373 Cincinnati.
3. The universe goes beyond the Milky Way- there are more galaxies than the Milky Way.
4. Hubble’s Law-redshift in light coming from distant galaxies is proportional to their distance.

Hubble Space Telescope is currently orbiting the Earth in the upper atmosphere. If not re-boosted, the telescope will crash through the Earth atmosphere between 2010 and 2032.

Hubble’s Constant-Hubble’s Law- a statement in physical cosmology which states that the redshift in light coming from distant galaxies is proportional to their distance. It is considered the first observational basis for the expanding space paradigm and today serves as one of the most often cited pieces of evidence in support of the Big Bang.
