When you hear about the Hubble Telescope what comes to your mind? Brilliant, huge, and genius all of these things describe the Telescope and Hubble himself. Edwin Powell Hubble once stated. What is the most well known telescope? Some may say Fermi Gamma-Ray Space Telescope, Spitzer Space Telescope, The Kepler Mission, but to others the Hubble Telescope is the most well known. The Hubble Telescope was named after one of the greatest scientist, Edwin Hubble.
Edwin Hubble was an astronomer that was born on November 20, 1889 in Marshfield, Montana. Edwin died on September 28, 1953 in San Marino, California. He was a very well known astronomer. Hubble purposed the idea of there being other galaxies other than the Milky Way and that the universe

The telescope was launched in 1990 by NASA. Hubble is about as long as two school busses (43.5 feet) and weighs about the same as two full grown elephants (24,500 pounds). It travels at about five miles per second. The telescope is 353 miles above Earth. Hubble faces towards space to take pictures of the stars, planets, and other galaxies. The telescope has a 94.5 inch aluminum-coated glass mirror. It observes light that is infrared, visible, and ultraviolet. The Hubble Space Telescope was scheduled to launch in October of 1986. Due to the Space Shuttle Challenger exploding after just a minute into its flight on January 28, 1986 all shuttles stopped for two years. The finished parts were moved to storage. The workers changed minor parts on the delay and continued to improve the solar batteries and upgrading other systems. On April 24, 1990 the telescope launched into space aboard the Space Shuttle Discovery. The telescope carried five different instruments. The instruments include the Wide Field/Planetary Camera, the Goddard High Resolution Spectrograph, the Faint Object Camera, the Faint Object Spectrograph and the High Speed …show more content…
The telescope made its one-millionth discovery in 2011. Before the Hubble Telescope scientist predicted the age of the universe to be around 10 to 20 billion years old. Hubble gave scientists the information to have a more precise answer of 13.7 billion years old. A main reason for this great discovery was Hubble’s observations of special types of bodies called Cepheid variable stars. Cepheid variable stars have very stable patterns of brightness that make them very effective at measuring distance. Although scientist know about the existence of dark energy now, because of the Hubble telescope they recovered the existence of dark energy in the early stages of the universe up to nine billion years ago. Dark energy is believed to accelerate the expansion of our universe, but it was first believed that after the Big Bang the expansion slowed

lifetime. Some of Edwin Hubble's greatest accomplishments were: Edwin Hubble proposed a classification system for nebulae, which are fuzzy little patches of light that are up in the sky. He discovered a variable star, called the Cepheid. It is located in the Andromeda Nebulae. Edwin Hubble settled decisively the question of the nature of the galaxies. Edwin Hubble's distribution of galaxies was determined to be homogeneous in distance. Edwin wanted to classify the galaxies according to their content, distance, shape, and pattern of brightness. By observing redshifts Edwin saw that galaxies were moving away from each other at a rate constant to the distance between them (this is known as Hubble's Law).
In the article from the official NASA website, NASA gives a list of Hubble’s accomplishments, which gives the reader a comprehensive picture of Hubble’s importance. Hubble has not only given astronomers the most detailed images of outer-space in existence, but also taug...
Just recently a major discovery was found with the help of a device known as The Hubble Telescope. This telescope has just recently found what many astronomers believe to be a black hole, After being focuses on a star orbiting empty space. Several pictures of various radiation fluctuations and other diverse types of readings that could be read from that area which the black hole is suspected to be in.
The Orion Nebula is a spectacular sight. Consequently, it has been a preferred target of the Hubble Space Telescope (HST) over recent years. The HST has provided a great deal of insight into the complicated process of star formation. In June of 1994, C.
I was born with an inherent fascination for all things celestial. Ever since I was young, I have been staring at the night sky trying to find constellations, or using my juvenile imagination to create my own. My efforts to find, view, and mentally catalogue everything the heavenly bodies have to offer has led me to employ some over-the-top measures, but the most extreme of them all might be the night I stayed awake through the wee hours of the morning to catch a glimpse of a meteor shower. Over the course of an entire year, the memory of this stupefying event is still as lucent and vivid as it was that very night so long ago.
in physics. In that same year, the researchers in Germany developed and launched two A-2 rockets that reached over 1.4 miles high. After the first launch, the team experienced failures, and more failures. However, they did create the world’s largest rocket. The A-4 rocket was 45 feet long, and had a 25 ton thrust which delivered a 1-ton warhead that could reach a target up to 160 miles away. In February of 1956, a new organization was formed for the development of the Jupiter Rockets. With these rockets, the Pioneer IV went past the moon and into orbit around the sun following its launch March 3rd,
The Hubble Telescope is the world’s first space-based optical telescope. The Hubble telescope received its name from American astronomer Dr. Edwin P. Hubble. Dr. Hubble confirmed an ever expanding universe which provided the basic foundation of the Big Bang theory. The first concept of the Hubble telescope came from Lyman Spitzer in 1946 who at that time was a professor and researcher at Yale University, Professor Spitzer believed that Earth’s atmosphere blurs and distorts light and a space orbited telescope would be able to surpass this problem. He spent nearly all of his life dedicated to making this concept into a reality. (http://hubblesite.org/the_telescope/hubble_essentials/)
In 1998 The Accelerating expansion of the Universe was discovered by two competing groups of scientists called the Supernova Cosmology Project and the High-Z Supernova Search Team that were led by Saul Perlmutter, Adam Reiss, and Brian Schmidt. And In 2011 they were awarded noble prizes in physics for their discovery of the accelerating expansion of the Universe. They did so by applying new technologies like computers and digital cameras to study and measure the spectrum and brightness of the light from other galaxies. The discovery proved the possible existence of a repulsive gravity force called dark energy that is responsible for accelerating the expansion of space. It challenged the previous assumptions of physicists whom believed that the expansion of the universe should be slowing down and it would eventually stop expanding or start contracting again because the attractive force of gravity. It also led to a change in the understanding of the workings of the universe. The discovery made by the two groups of scientists working and competing with each other has greatly added to the understanding of the workings of the universe and of how it began.
Redshift -and blueshift- describe how light changes as objects in space move closer or further away from earth and other planets. American astronomer, Edwin Hubble was the first to theorise and illustrate the redshift phenomenon and link it to the thought of an expanding universe. His observations, revealed in 1929, showed that nearly all galaxies he observed are moving away from each other. Hubble studied the Andromeda Galaxy, and to do this he used the 100-inch Hooker telescope located in South California. It was at that point when Hubble took long exposure images of distant galaxies. He was able to calculate the velocity of the pictured galaxies and was able to prove that everything is expanding and moving
Telescopes are commonly used and discussed by people in everyday life. They are instruments that were created to gather and focus light from a certain part of the ‘electromagnetic spectrum’. They generally are referred to when talking about wavelengths of light that can be seen by the human eye. These wavelengths are most commonly magnified and are studied ‘optically’, hence the name, optic telescopes. However there is a different type of telescopes that cannot be seen by the naked eye known as non-optical telescopes.
Telescopes are an arrangement of lenses or mirrors or both that gathers visible light, permitted direct observation or photographic recording of distant objects. A telescope can be used in many ways such as viewing stars, moons, planets, looking at the city from a tall building, or looking at wildlife. All telescopes are not the same, some are better than others. There are three different kind of telescopes. Reflecting which uses two mirrors instead of lenses, Catadioptric (CAT) which combines lens with two mirrors, and Reflectors. In this paper, I will be talking about a refractor telescope and explaining the terms of different terms that describe a telescope in addition special characteristics that makes a telescope a good choice for what you need it for.
One thing us as humans have never been able to fully understand is astronomy. Always having an unexplained mystery, astronomy also has served as a way to keep time and predict the future. The word “astronomy” is defined as the study of heavenly bodies, meaning anything in the sky such as stars, galaxies, comets, planets, nebulae, and so on. Many people, if not everyone, is amazed by the night sky on a clear, moonless night.
A telescope is a device used to magnify distant objects. Telescopes can be used to look at things on earth or at objects in space. The telescopes for use on the earth are known as terrestrial telescopes and the telescopes for looking into space are known as astronomical telescopes.
This telescope is the result of an international collaboration of 17 countries lead by NASA, European Space Agency and Canadian Space Agency. It will help us determine the geometry of the universe and enable us to establish whether the universe will expand forever.
