What the Hubble Telescope Has Taught Us

Another great advantage of the Hubble telescope, is that it allows Astronomers to have observations without the interference of cloud cover and illuminating glow of the atmosphere that is caused by the light from the sun. The reason why Hubble allows Astronomers to have such great observations without the above interferences, is because Hubble is in space and is orbiting the Earth. Also, being that Hubble orbits the Earth and is above the atmosphere, this allows Hubble and it's Astronomers to have a wide range view of the electromagnetic spectrum. One of the greatest things about Hubble is that it allows observations to be consistent and it's optical stability allows Astronomers to detect small changes in what they are

The Hubble Space Telescope has been sent into space to take pictures of our universe. Hubble has made more than 1.2 million observations since its launch on 1990. The Hubble weighs 27,000 pounds. It does not travel, it just takes

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 Discovery Channel Telescope secured the telescope’s name and they got the use the telescope first. They used the telescope for their television networks to make images. “Astronomers declared the instrument fully operational on the first day of 2015, ending a commissioning period that lasted 2½ years. In their advantage “The vast array of science projects that will be possible with this telescope will dazzle readers of this magazine for years to

The pictures you see on calendars. The pictures you set as your lock screen. The pictures you buy for your room. A lot of those cool graphic pictures are from galaxies and exploding rocks found in outer space outside of the Milky Way taken by the Hubble Telescope. The Hubble Telescope is a giant telescope that orbits the Earth and is able to see the understanding of what is happening in our universe according to mashable.com. Without the telescope we would not be able to know the things we know now about everything that is going on outside of Earth and outside of the Milky Way. Edwin Hubble created the telescope and the telescope is also named after him because of what he did to help out. He answered a lot of unanswered questions about our universe that no one else has been able to answer. Edwin Hubble is the most

First, it is important to distinguish that the size of the universe gives us a different view of our sky than what may actually be happening in it. In 1929, Edwin Hubble established a law that implies one of the more mind-bending, Star Wars worthy concepts of astronomical study: what we see is not only far, far away, but is also long ago (http://hyperphysics.phy-astr.gsu.edu/hbase/Astro/hubble.html (Links to an external site.)Links to an external site.). Light takes so long to travel from even some of the closest objects to our solar system that we are not capable of viewing things in real-time. Objects we see at night may, in fact, be long gone from their regions of the sky.

The Hubble space telescopes findings have transformed the way scientist view the universe. Hubble has sent some of the most detailed images of the cosmos. These images have been the best images that humankind has ever seen. Over the years it has send back images of mysterious black holes, life cycle of star and picture of new planets. Even photos of the universe shortly after the big bang. Before hubble some of the most remarkable cosmic phenomenon such as black holes, were unable to be examined as they trap all light. Hubble was able to describe black holes due to what occurred around them. As black holes devour the the remaining of galaxies and hot cosmic

The only thing standing in Edwin’s way of getting a clean picture of the stars was this thing known as the Earth’s atmosphere, which because of the fluidic gas and dust that make up the atmosphere it often “blurs visible light, causing stars to twinkle and making it difficult to see faint stars.”(Dunbar) As this makes his job virtually impossible, a German scientist comes up with the idea of a telescope in space to not only see farther but also to see clearer, this was a crucial turning point in Hubble’s findings and will eventually lead to the one of the greatest and most recognized theories around the world.

On April 24th of 1990, The Hubble Space Telescope was launched. This was an important event for NASA, because they finally had something to looked further into the space. The Hubble Space Telescope was known as (HST), and it was sent to orbit around our earthly planet. Did you know it took only 97 minutes to orbit around our planet? Hubble Space Telescope helped change the NASA’s thought on the universe because,

The telescope is an instrument which increases our ability to observe far away objects through the collection of electromagnetic radiation, the most prevalent type of telescope is the optical telescope which collects light, however there are other kinds of telescopes which collect UV and X -Rays. Optical telescopes use lenses to redirect light to a specified point. Different lenses are used for different magnifications of celestial objects. This essay will be mainly discussing optical telescopes.

Since its conception in 1958, NASA has been a pivotal organization in innovative technology and space exploration. With inventions such as the Hubble telescope, or the space shuttle, NASA has provided the world with existential research regarding space. With a renewal of popular interest in NASA, the organization would be able to continue contributing vital research in the medical, and technological fields, as well as the future exploration of space as humans know it, and the future habitation of other planets.

However, Hubble understood that teaching was not for him, so after one year he wrote to Moulton, his astronomy professor at University of Chicago, about rejoining the university as a graduate student. Hubble studied at Yerkes Observatory in Wisconsin, which was equipped with a 40 inch refractor. His first discovery was made when comparing images of nebulae over a few years. He noticed that there were faint changes occurring in the nebulae demonstrating that changes in nebulae could occur (Osterbrock, 1990).. Hubble completed his doctorate in 1917(Brown, n.d.), to which his thesis was titled “Photographic Investigations of Faint Nebulae.” His thesis would foreshadow many of his future discoveries as it emphasized that the nebulae exist outside of the Milky Way and possibly millions of light years away (Osterbrock, 1990). Upon completion of his Ph.D., Hubble was offered a job at Mount Wilson Observatory near Pasadena, California (Brown, n.d.). The observatory was home to the most powerful telescope in the world at that time, the new 100-inch Hooker Telescope. It was here where Hubble would stare at the stars and discover so much about the cosmos (Osterbrock,

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

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. At the focal point, half transparent mirrors distribute the light to the various scientific instruments. 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. The primary mirror weighs 1825 pounds and the secondary mirror weighs in at 27.4 pounds.

As proposed in an article posted on amazing space.org, “The telescope, a basic reflector with a 94.5 in (2.4 meters) mirror.” While also having being a second mirror that the light bounces to to. Within that mirror, many instruments were compacted together that allowed for clear and visible views in infrared and ultraviolet light. It was different compared to any other ground based telescope whereas it allowed astronomers to observe and witness details that had never been seen before due to Earth being in the way for those other telescopes. The telescope revolves around the earth completely every ninety-seven minutes at the speed of five miles per second, allowing for many observations in space. The observations occur when light hits the main mirror and then bounces towards the second mirror in which the second one focuses the light. The telescope began to be created in 1977 and was originally supposed to launch during the year of 1985. Unfortunately an accident had occurred when a space shuttle challenger exploded and flights into space took a halt. It was finally launched on April 4th of 1990 once the halt had stopped. The improved observations had begun and the history of astronomy had changed. Unfortunately there were some minor setbacks that had to be dealt with. One setback was that the primary mirror was ground incorrectly in which the curve of it was too flat. It was off just
