Hubble Space Telescope Essay - 1737 Words

According to a newsletter sent out by the National Aeronautics and Space Administration (NASA), the purpose of the Hubble Space Telescope was, and is, to gather light from cosmic objects so scientists can better understand the universe around us. Up until the deployment of the Hubble Space Telescope, all telescopes were Earth based and had the disadvantage of having to peer at the stars through the Earth’s atmosphere. The Earth’s atmosphere provides a large amount of distortion when viewing very far objects, like space, through a telescope. Placing a telescope in space eliminates the distortion and provides images that are significantly clearer and in turn, easier to examine. The Hubble Space Telescopes six different science instruments†¦show more content†¦The fourth important instrument is the Near Infrared Camera and Multi-Object Spectrometer, which is basically Hubble’s heat reader. It is very sensitive to infrared light which makes it useful for ob serving objects tainted by gases and dust. It is also used to peer into the deepest parts of space. The fifth important instrument is the Space Telescope Imaging Spectrograph, which is a utility instrument that separates the light from the cosmos into its component colors. It is also used to study black holes, the composition of galaxies, and the atmosphere of planets around all stars. The sixth and final important instrument is called the Fine Guidance Sensors, which target devices that lock on to â€Å"guide stars† and measure their positions in relation to the objects being viewed. The sensors also perform celestial measurements. The Hubble Space Telescope is powered by solar cells which are solid-state electrical devices that convert the energy of light directly into electricity by an effect called the Photovoltaic effect. When many solar cells are put together they are called solar modules which can also capture energy from sunlight. When many modules are placed together it is called a solar panel. Hubble had many problems finding funding for the telescope.

Bigger and better telescopes were built all over the world. Planets, stars, and nebulae which could not be seen by the naked eye were now being routinely noted and logged. Such is the case with the fantastic discoveries for which the Hubble Space Telescope has been responsible during the twentieth century.

Telescopes were invented so that people could better view the stars and planets. Eventually, someone had the grand idea to launch one into space. It was named after the famous astronomer Edwin Hubble. Despite the trouble it has given engineers and astronauts since its launch, the Hubble space telescope has led to dozens of scientific breakthroughs and has changed the way humankind sees the universe.

There are many different telescopes used in astronomy, most of which are massive, and have special qualities. Although they all have great features and are well working instruments, they need innovations sometimes. Over the years they have discovered mind boggling objects, and they are still looking. Telescopes have evolved, and helped astronomers, in many ways since the first telescope was built.

From simple optical telescopes to radio telescopes and high-energy telescopes, people constantly improve observational technologies to make more discoveries. This scientific development reached its climax as people launched a revolutionary telescope above the a tmosphere for a better quality of image. These revolutionary changes in observational technology help this universe be more comprehensive to human. The first telescope-like device appeared in 1608 when a lens-makerRead More Revolution in Cosmology Resolves Dispute over Universes Age1430 Words   |  6 PagesRevolution in Cosmology Resolves Dispute over Universes Age Just under seven years ago, astronomers using the Hubble space telescope presented results they hoped would help answer one of the most contentious issues in astronomy of the 20th century – the question of the distance scale of the universe. But there was some unease when the result was announced. According to the report, other galaxies were close enough that, extrapolating backwards from their current rate of recession and making adjustmentsRead MoreAmerican in the 90s Essay736 Words   |  3 PagesThe era of the 1990’s was an explosive time in American history both figuratively and literally.

In 1946, an astrophysicist named Dr. Lyman Spitzer proposed that a telescope in space would reveal better and clearer images that are even far from earth than any ground telescope. This idea was very extravagant because no one had yet launched a rocket into outer space. As the US space program excelled quickly over the early years, Spitzer lobbied NASA and Congress to develop a space telescope.
