Essay on Hubble Telescope

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

Dark matter is a type of matter that is invisible, but accounts for most of the mass and structure of the universe. Hubble allowed scientists to observe how dark matter bends the light of galaxies that are far away through gravitational lensing. Scientists could then theorize about the existence of dark matter. Due to Hubble’s unique viewpoint, scientists could also map where dark matter is located and how it is distributed in galaxies. Hubble also played a large role in the discovery of dark energy. Dark energy is a repulsive force that causes the universe to expand at a faster and faster rate. Hubble not only detected the presence of dark energy, but also that it has been around since almost the beginning of the universe. It was used to look back in time at supernovae, which are used to trace how the universe expanded. Only Hubble could be used for this task because telescopes on the ground would be unable to see these very distant and faint supernovae. Hubble changed the field of astronomy through its part in discovering dark matter and dark

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

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,

This has helped us learn far more about the origins of our Universe and the formation of galaxies from around a billion years after the creation of the Universe, where the galaxies appear to be very shapeless and small, to today where they are larger and formed into spirals or discs. The Hubble Space Telescope has helped pinpoint the age of the Universe to 13.7 billion years22 by studying 31 Cepheid variable stars22, whose fluctuating brightness can be used to calculate their distance thus the expansion and therefore age of the Universe. Knowing the age of the Universe helps astronomers and cosmologists model the Universe and its evolution over its lifetime accurately, which is immensely valuable information to

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.

The Hubble sequence is also known as the “Hubble tuning- fork” because of the shape it is represented by. The Hubble scheme divides galaxies into three broad classes based in their appearance.

Hubble helped determine the age of the universe and the way galaxies are formed. Revealed extraordinary detail about the process by which sun-like stars end their lives as planetary nebulae. The telescope allows to study the universe across a wide swath of the light spectrum structure of the universe and map the distribution of elements fundamental to life. Astronomers believe they formed the most distant objects with Hubble with a Distance of 13.2 billion years away. According to nbcnews.com, Scientist Labb`e stated that previous searches have found 47 galaxies at an adequately later time, when the universe was about 650 millions years old. Hubble has also discovered dark matter. Dark matter is invisible, but reveals its existence via gravity, makes up roughly 23% of the universe. The telescope made it easier to understand how Dark Matter behaves and could help scientist figure out more detail about dark matter. Hubble has greatly expanded astronomers knowledge of the Universe. Before the telescope, distance to far off galaxies were not well known. Hubble’s millionth exposure is of the Planet HAT-P-7b, a gas giant planet larger than Jupiter orbiting a star hotter than our sun. HAT-P-7b, also known as 2b, has been studied by NASA’s planet hunting Kepler observatory after it was discovered by ground- based observations. Hubble now is being used to analyze the chemical composition of the planet’s

“The Hubble, has given us nothing less than an ontological awakening, a forceful reckoning with what is the telescope compels the mind to contemplate space and time on a scale just shy of the infinite.” implied Ross Anderson, an engineer. With this one telescope, created by a normal astronomer, scientists and astronomers are able to see space as never seen before. They are able to make mind boggling observations that contemplate space to an infinite scale. Thousands of discoveries about space have been observed through this lense and without the magnitude of high level instruments compiled into this large instrument most of these observations would never have been discovered. As proposed by Floyd E. Bloom a researcher, on izquotes.com, “As

“What is this object?” Some of you may ask. Well it is easy. The Hubble Space Telescope is basically your average telescope on steroids. It can see as far

Here are Some intriguing facts about the Hubble Space Telescope. The Hubble Space Telescope was launched aboard Space Shuttle Discovery on april 24 1990and has been running for 27 years. Hubble has been around the earth 148,000 times and has racked up an impressive mileage of 3.8 billion miles. The HST has made over 1.3 million observations of 42,000 celestial bodies. Approximately 2 terabytes of data are added to HST database everyday. astronomers have used Hubble data to publish over 14,600 papers on the cosmos and has been referenced over 600,000 times in

Catadioptric telescopes are those that use both mirrors and lenses to produce an image. The most common or popular type of catadioptric telescope is the Schmidt-Cassegrain telescope. Schmidt-Cassegrain telescopes (SCT) are a catadioptric design, meaning they use both lenses and mirrors. SCTs are primarily reflecting telescopes, but they use a corrector lens to eliminate aberrations that would result from the mirror design alone. In an SCT the incoming light passes through the Schmidt corrector lens (also called a corrector plate) at the front of telescope. It is reflected from a concave primary mirror at the back of the scope which focuses the light to the front of the telescope where it is reflected again by a smaller, convex secondary mirror. Finally, the light travels back through a hole in the primary mirror to the rear of the scope where an eyepiece is located for visual observing. (Starizona.com, 2015)
