The Hubble telescope has offered modern man, a glimpse into the deep reaches of space that Galileo Galilei could have only dreamed of. The Hubble is in the above the haze of our atmosphere, this provides a benefit to the Hubble that is not available on the earth. The Hubble being free of the atmosphere this allows for clear pictures. Another benefit is that the Hubble does not have to compete with light pollution like ground based telescopes. The Hubble was launched April 24th 1990 since it being in orbit for over 26 years. Since it has been in orbit around Earth. The Hubble has been instrumental for expanding man kinds understanding of our local solar system, galaxy, and the universe. The Hubble telescope has received multiple visits from multiple space shuttles for maintenance, repairs, and upgraded observational tools. With twenty-six years of service time, the Hubble has observed and produced some of the most awe inspiring photos of our planets, stars, and deep space. The Hubble Deep Field (HDF) is when the Hubble was pointing to one section of the nights sky, observing and focusing on as much light as possible, within this one section of the night sky. The idea for the Hubble Deep Fields originated in results from the first deep images taken after the __repair in 1993__. These images showed many galaxies, which were often quite unlike those we see in the local Universe and could not otherwise be studied using conventional ground-based telescopes. The first Deep Field, the Hubble Deep Field North (HDF-N), was observed over 10 consecutive days during Christmas 1995(http://www.spacetelescope.org/science/deep_fields). The information gained by this experiment has allowed man kind to essentially see the big bang, This of course spurred the scientific community to want to have better equipment up on the Hubble for better quality and high definition photos.The Hubble Ultra Deep Field from 2004 represents the deepest portrait of the visible universe ever achieved by humankind. Using the improved capabilities of the Advanced Camera for Surveys, the __camera__ installed during the __2002 servicing mission__, a new Deep Field was observed, in the constellation of Fornax (the Furnace)(http://www.spacetelescope.org/science/deep_fields/). The Hubble has been in operation for a long time, over the years parts are going to wear down and then they are going to reach a point of no return. These setbacks can have a domino effect that have and can cause issues down here on earth. For example this happened In late September 2008, only two weeks before the mission was to launch, a malfunction occurred in one of the systems that commands the science instruments and directs the flow of data within the telescope. The problem was fixed by switching to a backup system, but NASA was unwilling to leave the telescope without a spare. The mission was delayed until May while engineers and scientists tested and prepared an existing and nearly identical system. Astronauts were able to install the spare Science Instrument Command and Data Handling unit in addition to all previously scheduled tasks( http://hubblesite.org/the_telescope/team_hubble/servicing_missions.php).
Hubble Witnesses Massive Comet-Like Object Pollute Atmosphere of a White Dwarf
Scientists using NASA’s Hubble Space Telescope have witnessed a massive object with the makeup of a comet being ripped apart and scattered in the atmosphere of a white dwarf, the burned-out remains of a compact star. The object has a chemical composition similar to Halley's Comet, but it is 100,000 times more massive and has a much higher amount of water. It is also rich in the elements essential for life, including nitrogen, carbon, oxygen, and sulfur.
These findings are the best evidence yet for a belt of comet-like bodies orbiting the white dwarf, similar to our solar system's Kuiper Belt. These icy bodies apparently survived the star's evolution as it became a bloated red giant and then collapsed to a small, dense white dwarf.
Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full moon. The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 2003 and 2004. By collecting faint light over many hours of observation, it revealed thousands of galaxies, both nearby and very distant, making it the deepest image of the universe ever taken at that time. The new full-color XDF image is even more sensitive, and contains about 5,500 galaxies even within its smaller field of view. The faintest galaxies are one ten-billionth the brightness of what the human eye can see. https://www.nasa.gov/mission_pages/hubble/science/xdf.html
