Telescope essay

The Hubble Telescope mirrors are made of glass and coated with multiple layers of pure aluminum that are three-millionths of an inch thick and a coat of magnesium fluoride that is one-millionth of an inch thick to make them reflect visible, infra-red and ultraviolet light.

After being deployed, astronomers immediately found out that the telescope could not be focused. By looking at the different wavelengths or the spectrum of light from a celestial object, you can tell many of its properties and features.

Inan astrophysicist named Dr. The Corrective Optics Space Telescope Axial Replacement consisted of several minute mirrors that would intercept the beam of the flawed mirror and relay the corrected beam to the scientific instruments at the focus of the mirror.

Telescope essaythe telescope was finished and was named after Edwin Hubble, an American astronomer whose observations of variable stars in distant galaxies confirmed that the universe was expanding and gave support to the "Big Bang" theory.

After a long delay due to the Challenger disaster, the Hubble Telescope went into orbit in Most of the time, interstellar gases and dust can create a barrier for our vision of visible light from various To do this, the Hubble Telescope is equipped with various scientific instruments.

The digital data is then transformed into amazing pictures that we can look at on the news, online, magazines, and newspapers. The primary mirror weighs pounds and the secondary mirror weighs in at This idea was very extravagant because no one had yet launched a rocket into outer space. Then the secondary mirror reflects the light through a hole in the center of the primary mirror to a focal point behind the primary mirror.

Scientists came up with a solution to correct the defect in which they came up with a replacement "contact" lens called COSTAR.

The light that is detected by the CCD are digital signals, which are then stored in on-board computers, which then are relayed to earth to study and learn from. The Hubble Telescope was reported to be 50 times more sensitive than ground-based telescopes with 10 times better resolution.

It held five scientific instruments, had more thanparts, and had 26, miles of electrical wiring. The Hubble telescope is a compound telescope design where light enters the telescope through the opening and bounces off the primary mirror to a secondary mirror.

The WFPC2 can take images through various filters like red, green, and blue to make natural color pictures. InCongress approved funding for the development of the space telescope and NASA named Lockheed Martin Aerospace Company as the prime contractor to oversee its construction.

All four of the CCD chips are exposed to the target at the same time, and the target image is centered on the desired CCD chip in either high or low resolution. At the focal point, half transparent mirrors distribute the light to the various scientific instruments. The Hubble Telescope took a total of eight years to develop.

There are various scientific instruments that are needed for the Hubble Telescope. Lyman Spitzer proposed that a telescope in space would reveal better and clearer images that are even far from earth than any ground telescope.The Hubble Space Telescope is a telescope placed in orbit over our planet’s atmosphere.

This particular positioning (outside the earth’s atmosphere) allows the set of device to take sharp optical images of otherwise very faint spatial objects.

The telescope is a device that permits distant and faint objects to be viewed as if they were much brighter and closer to the observer.

The first person to use the telescope to observe the sky was Galileo. The idea of the project is that because the telescope is high in the sky, the infrared blocking water vapor on the ground will not affect the telescope and the telescope will have a much clearer view of the infrared universe (than if a telescope.

The Hubble telescope is a compound telescope design where light enters the telescope through the opening and bounces off the primary mirror to a secondary mirror.

Then the secondary mirror reflects the light through a hole in the center of the primary mirror to a focal point behind the primary mirror. Essay about The Invention of the Telescope: Galileo Galilei - "Nature is relentless and unchangeable, and it is indifferent as to whether its hidden reasons and actions are understandable to man or not." This quote was once said by one of the most famous scientist in history; his name was Galileo Galilei.

The telescope has changed the world greatly by being able to make distant objects appear closer and more distinct. It helped scientists to discover things that could not be seen by the naked eye. For example, a lot of things in space would have not been discovered if it were not for the telescope.

Also, it helped the world of eyesight.
