The Physics Of Astronomy And Astronomy

“classified Hubble as a Cassegrain reflector, who was among the first to suggest a basic optical design.”1 The Hubble space telescope was launched and deployed in April of 1990, which “marked the most significant advance in astronomy since Galileo's telescope. Thanks to four servicing missions and more than 25 years of operation, the view of the universe and humanity's place within it has never been the same.” 2 In describing how

The telescope is an optical instrument designed to make distant objects appear nearer. It contains an arrangement of lenses or mirrors or both that gathers visible light, permitting direct observation or photographic recording of distant objects. (Lacki, B. C. 2011). With the use of telescopes we have been able to learn a lot more about the planets in our universe. It has helped us understand about some of the history of everything around us. Also it has been able to track asteroids and comets or any randomly flying objet in outer space that might become threatening to our planet.

The Hubble costs about 2.5 billion dollars to make. Also it has 6 cameras and sensors. It was launched in the honor of Edwin Hubble (also why the telescope was named after Edwin). As the telescope goes around in orbit with a light spectrum from the ultraviolet to near infrared it is able to take some very incredibly close and clear images. The telescope uses a digital camera to capture all of the great images and uses radio waves to send the pictures through air back to the Earth so we all are able to see what great things are happening outside of the Earth. With all of the information we get from the telescope we are able to stars being born and stars die. We are able to see galaxies that trillion miles away. It was able to see a comet pieces crash into gases above Jupiter. Also, we have been to discover moons that are around pluto that have never been able to see before. Additionally, we are able to understand how planets and galaxies form. We have so much information and have discovered so many new things from the Hubble Space

Although telescopes were a revolutionary discovery they would come at a price. As described in my second site “Ground-based telescopes cost about 10 to 20 times less than a comparable space telescope...Because of their sensitivity to environmental factors, ground-based telescopes would need to be set up in specific spots. Scientists and engineers must take different physical factors into consideration when finding a suitable location to place a ground-based telescope.” These disadvantages make it difficult to get the full experience of using the telescope correctly and using it to benefit the viewer.

Infrared and ultraviolet telescopes are also used which makes it easier to differentiate what are actually planetary nebulae.

Many scientist used telescopes to look at the planets and turned up the brightness. It helped showing how far the planet was and to show there are planets between the star and earth. Scientist started looking for pulsating stars and using them to find different planets. To find smaller planets scientist used NASA’s Kepler telescope. The telescope was very helpful for NASA and it proved that there are smaller planets. They figured out that some stars have planets. NASA’s help was very successful and they found different planets by the

Measuring both telescopes to Galileo’s telescope and the Hubble Space Telescope, they are all remarkable with their individual functions and purposes. The Hubble Space Telescope is more high-technology than the other three and has made tons of findings from the outer aspect of the Earth. Though Galileo’s telescope was not as impressive compare to the modern ones, knowing the early times was limited but Galileo still has the idea and ability to make it was impressive and worth the

The Hubble Space Telescope is a telescope that was launched into space in 1990, April 24th. Its primary function was to take pictures of stars, planets, moons, galaxies, etc. This type of telescope is different from a telescope such as the Hooker Telescope as it is in space, rather than on Earth, and was used for different things. Over the many years that this extraordinary telescope has orbited in space, it has helped scientists with many new discoveries and refined previous theories or beliefs. One of the biggest discoveries this telescope has made is the discovery of galaxies that we did not know of previously because they were so far away. This discovery was very important as it has lead scientists to calculating a more accurate age of the universe. The Hubble Space Telescope made this discovery by observing Cepheid variables, which are stars with the same average brightness. Although, their brightness is essentially the same, the stars would seem either brighter or dimmer depending on its position in relation to Earth. For example, if one Cepheid variable was 100,000 light years away and another Cepheid variable was 200,000 light years away, the second star would seem dimmer as it is further away from the Earth and our perspective makes it look like it is not as bright. Scientists can use this observation to work out around how far away a Cepheid variable, and ultimately a galaxy, is from the Earth. Using this information and the pictures taken by the Hubble Space Telescope, scientists were able to work out a more accurate age of the universe which was around 13.75 billion years old. Without this sort of technology, we wouldn’t know as much about the universe as we do now and we may not have been able to refine our knowledge on the age of the universe. To sum up, the Hubble Space Telescope is an important piece of

So many adults and young people alike are in awe of the seemingly limitless skies that are made visible on a clear night. But while we stare in wonder, without the help of space-borne telescopes, we could only imagine what threats the cosmos has to offer.

The NASA Spitzer telescope is uniquely situated in space to be able to help astronomers solve the mysteries of not only this new Milky Way exoplanet, but for all of the other possible new planets, stars, and other items to be found some day in the universe. It is part of the big adventure of searching the skies to figure out how and where planets are situated in our Milky Way galaxy.

The most advanced telescope today in the 21st Century differs vastly to the ones invented during the Renaissance time era. Many of these advanced telescopes are stationary to a specific area and are enormous in size. These telescopes are very advanced and often require more than 1 person

Telescopes make faint images more clear and bright (Morgan & Dinwiddie pg. 118-119). The bigger the telescope, the sharper the image it shows (Morgan & Dinwiddie pg. 118-119). Telescopes collect light to focus on objects, and targets for a better quality image (Morgan & Dinwiddie pg. 118-119). On professional telescopes, lasers guide it to the focus, so the pictures don’t turn out blurry (Morgan & Dinwiddie pg. 118-119). The Hubble Vision telescope has provided the best images of galaxies and planets, such as Uranus, founded by William Herschel (Goldsmith

The science of astronomy has come a long way. For instance, Galileo discovered the first four moons of Jupiter. Nicolaus Copernicus proved that the Earth wasn’t the center of the solar system. But one man will change all that is known about space. Edwin P. Hubble had discovered a amazing discovery that rocked the whole astronomy community, there were other planets, stars, and galaxies outside of our own. Hubble’s discovery changed everything man has ever known about the stars.

The Hubble Space Telescope is one of the most amazing machines in orbit right now. 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. In 1975, the European Space Agency and NASA began to develop the telescope that would change astronomy for ever. In 1977, Congress approved funding for the development of the space telescope and NASA named Lockheed Martin Aerospace Company as the prime contractor

As stated on nasa.gov, “Hubble has made more than 1.2 million observations since it’s missions began in 1990.” Hubble has also expanded astronomers knowledge about the universe and space as a whole. The most famous observation made by this telescope was that of galaxies beyond our own, Milky Way, and discovering that the universe is much larger than further predicted. Before this telescope, ground based telescopes could only see into our galaxy and could not reach any further. Therefore, it was thought that the Milky Way was the only galaxy included in space and the universe. Due to the fact, Hubble’s telescope, expands and allows for the study across a wider light spectrum, astronomers can see beyond further predicted. Another famous observation, studied by astronomers was that of the study of uncharted territories of the cosmos. As proposed on hubblesite.org, “It became increasingly clear to astronomers that Earth’s atmosphere distorted starlight, which made it difficult to obtain razor-sharp views of celestial objects. The idea of placing a telescope in space, above Earth’s turbulent air, had been kicked around for several years. But scientists pondered how to transport a telescope into space.” That was until, Hubble’s creation that displayed imagery of the cosmos. Once again it had accomplished a feat that had troubled ground based telescopes. In
