Hubble, The Space Telescope That Can See The Universe The Hubble Space Telescope is a large telescope in space weighing 24,500 lbs. NASA launched Hubble in 1990, "Hubble is named after Edwin P. Hubble, He was an astronomer"(Rosario). Hubble travels around the Earth taking pictures of planets, stars, and galaxies. "It has seen stars being born and stars die, and it has seen galaxies that are trillions of miles away." Scientists have learned a lot about space from Hubble pictures (Dunbar). In the same way, Hubble can see space better than telescopes on Earth can, it's a different kind of telescope than one would usually use, you don't look through the Hubble Telescope. Hubble uses a high-tech camera that takes pictures then it uses radio waves to send the pictures through the air back to Earth. …show more content…
The "Telescope found a moon around Neptune that had never been seen before, the new moon is Neptune's smallest known moon and is just 12 miles wide" (Kramer), It took around five years of looking through new photos that Hubble had taken before finding the tiny moon. Because of the pictures that Hubble has provided, scientists have determined the universe is around 14-billion years old. "Hubble's images of the galaxies are recorded in shades of black and white, not color. The final color images are artificially made by the scientists through colored filters" (InVisible Culture). The Hubble Telescope is traveling 350-miles above the surface of the earth and can observe fur away galaxies, but there are a couple of nearby objects it cannot look at. One of these is the Sun because it is so bright it would damage the sensors on the telescope in addition to the sun the planet Mercury is another, it too sits too close to the Sun, so Hubble cannot observe
Distances so vast that the light from those areas in space is billion years old. Illingworth was able to see these ancient giants with the Hubble Space Telescope. A telescope that is high above the atmosphere, because it can distort the image. 100 sextillion miles or 17,010,779,502.32 light years is the most distant galaxy Illingworth
Four weeks after space-walking shuttle Endeavour astronauts repaired the Hubble Space Telescope in December 1993, an ecstatic Maryland Senator Barbara Mikulski waved a Hubble picture of the core of the spiral galaxy M100 at her naysaying colleagues. Today, Mikulski could host a Capitol Hill star party: The orbiting telescope has generated more than 100,000 photos of celestial objects, including a cemetery of dying stars, elephant trunks of dust and hydrogen gas twisting in the Eagle Nebula, jovian storms and aurorae, the rocky rings of Saturn and the colossal supernova smoke rings blown from an exploded star, to list a few. Hubble's pictures do double duty not only as congressional lobbying props, but also as screen savers, T-shirt prints, calendar photos, a background for the "Babylon 5" science fiction TV series and even planet trading cards to be provided soon to schoolchildren.
Who has not ever, even if just for a brief moment, looked up at a dark but vividly lit starry night sky and wondered how far those seemingly little lights reach, and if that beauty goes on forever, or if it ends at some point. I believe this question has been pondered by mankind since our creation, and early astronomers are proof of this pondering. Telescopes began as a way for these early astronomers to chart the stars and planets and their movements as they searched for more than what just the naked eye could offer them. In the early 17th century, craftsman began making telescopes, though the tools to invent them had been available for centuries before. Early telescope were called spyglasses and needed improvement. Galileo's Optic Tube, also known as the Galilean telescope is an example of the early creation of refracting telescopes. There were a few different makers and models of refractor telescopes but it was soon discovered they could make a better telescope. With the beginning of the 18th century came the reflecting telescope, which is also called a reflector; an optical telescope that uses either a single curved mirror, or a combination of curved mirrors. There are many types reflecting telescopes: there is the Gregorian telescope, the Cassegrain telescope, and the Ritchey–Chrétien telescope. But today, we are going to be talking about one telescope in particular; "the 200 inch Hale Telescope, which for decades stood as the largest telescope on the planet"(1), from 1948 to 1976. The Hale telescope opened up the skies in ways we never imagined.
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).

Novice stargazers are often disappointed because they cannot see the rainbow of colors that appear in celestial photos taken by the Hubble Telescope. This is because the human eye’s color sensors do not function well under low light levels.
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.
What is astronomy? Astronomy consist of a lot of things that make up our solar system such as: the nine planets, asteroids, meteorites, the moon and the sun. Astronomy is also a fascinating hobby that can be followed by anyone. You do not need to be, as some people seem to imagine, ‘mathematically-minded’ , in order to start, or even to become a very experienced observer. Yet astronomy is one of the few hobbies where not only can you gain great enjoyment, but if you feel want to can very easily make observations of great scientific value.
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/)
What exactly is a space probe? A space probe is an unmanned space vehicle that is designed to explore our solar system and everything in it by using very high-tech instruments. Some common instruments that you will find on a spacecraft include magnetometers, radiometers, cameras that are sensitive to infrared and ultraviolet light, and tools that can detect micrometers, cosmic rays, solar winds, and gamma rays. Space probes study structures in our solar system for various reasons. They use onboard computers to send data back to Earth. In order for these space probes to actually reach space, they must be launched with enough energy to escape the gravitational pull of the Earth. Space probes are not designed to return back to Earth.
People have been venturing out into the universe for many years now. In addition to satellites, both women and men astronauts have traveled into space to collect data about the universe. The first human being, the first animal, and the first spacecraft in orbit, were all achievements of the Soviet Union.
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.
