The '''Hubble Space Telescope''' is an American space probe in earth orbit that explores objects if space. It is operated by [[NASA]]'s [http://www.nasa.gov/centers/goddard/home/index.html Goddard Space Flight Center] and the [http://www.stsci.edu/resources/ Space Telescope Science Institute]. The [[telescope]] was launched April 25, 1990 and began operations soon thereafter.

The telescope is named after astronomer [[Edwin Hubble]] whose observations of galaxies led him to the discovery that the universe is expanding.

'''The Hubble Ultra Deep Field''' is a picture taken by [[Hubble Telescope]]'s Advanced Camera for Surveys (ACS) and the Near Infrared Camera and Multi-object Spectrometer (NICMOS) of an "empty area" one tenth the diameter of a full moon when viewed from Earth. The 11.5 square [[arc minute]] area is equivalent to a grain of sand held at arm's length. Taken over a period of almost 11 days, the picture required 400 orbits around Earth and 800 exposures, which is equivalent to approximately 1 million seconds of exposure time. With an estimated 10,000 [[galaxy|galaxies]] in this image, nearly every speck of light is an entire galaxy or group of galaxies.
