There may not be a more humbling experience than looking at Earth's place in the Galaxy in relation to other heavenly bodies in Ultra Deep Field.
Hubble scientists attempted to accomplish something extraordinary in 1996, so they trained the Hubble telescope on a part of the sky that appeared absolutely empty. A patch no bigger than a grain of sand, held out at arm's length and devoid of any planet, stars or galaxies. The area was close to the familiar constellation, the Big Dipper.
Hubble, a space telescope launched in April 1990, has been orbiting the earth ever since. Its unparalleled advantage lies in the fact that it is stationed outside of Earth's atmosphere, thus giving it a clear view of space.
It was somewhat a risky undertaking by the astronomers, considering that observation time on this telescope is in very high demand and some questioned whether it would be wasted looking at mere darkness. Others feared that the images thus collected would be as black as the space at which it was being pointed.
