Hubble and James Webb Search For the Edge

Hubble and James Webb Search For the Edge""," It certainly was a lot of money to pay for a telescope that circled the Earth and could not focus. The Hubble would quickly become an object of ridicule and the subject of numerous jokes on late night television. Fifteen years later, it is very safe to say that nobody is laughing now. For more than a decade, the Hubble telescope has captured many of the most spectacular images of outer space. However, even though the final planned servicing mission for the telescope is scheduled for October of this year, the Hubble's best pictures of the Universe may be yet to come. The space walks will be necessary for astronauts to install new scientific instruments to enhance the telescope. During the mission, the Hubble will receive a new set of the gyroscopes that will stabilize the telescope, and batteries and thermal blankets to extend Hubble's operational life until at least the year 2013. The Hubble Telescope is responsible for dating the age of the Universe at 12-14 billion years. It cannot see the period after the big bang when the Universe began an expansion that continues to accelerate to this day. The years after the Big Bang are known for the formation of the first stars and the creation of the first galaxies. It is a search that will be undertaken by Hubble's successor, the James Webb Space Telescope (JWST). However, in order for the James Webb Space Telescope to see objects at the edge of the Universe after the Big Bang, it will need to be a much different telescope than the Hubble. This distance puts the telescope well beyond the reach of space shuttle servicing missions, and therefore the telescope is expected to have a much shorter life than the Hubble. Finally, powerful cooling systems will help to dramatically lower the spacecraft's temperature to a -447 degrees Fahrenheit in order to be cold enough to complete its mission. In contrast, the Hubble was equipped to capture mostly visible light and ultraviolet parts of the spectrum. Scientist call this phenomenon red shift, and it means that light from the most distant (and therefore oldest) object is deep in the infrared part of the light spectrum, a part of the light spectrum which the Hubble is currently unable to see. It is hoped that the telescope will allow astronomers to observe the birth of galaxies, the physics of star and planet formation, and the entire early development of the Universe. Hubble was the trailblazer in the search of outer space through time. It is a scientific search to see the edge of the Universe, a view from the distant past that will increase our understanding of space, for the world of tomorrow. TRY SOMETHING NEW JUST CLICK HERE
