Transcript of Telescopes
Welcome to the Wonderful World of Telescopes How Telescopes Die Different Kinds Purpose Impact on Society How to use one Famous Astrologists Dazzling Facts Gamma Ray- Used to detect gamma ray energy from other parts of our universe. Has an incredible amount of energy. One of the later installements of telescopes. Requires more detailed designs which would insure that the gamma reading will work properly. X-Ray- Although it can work on Earth it works better in space, this is because our atmosphere interferes with the telescopes X ray technology. Used to study mainly stars, the sun, and supernovas. Reflector- Uses a mirror to gather and focus light. The two mirrors reflect the light so you can see the image which helps magnify the image. Radio- Used to study galaxies, quasars, and stars. Contains a large radio antenna and a sensitive radio reciever/ radio meter. Is able to measure weak radio emmissions. Refracting- Uses two lenses made of different kinds of glass, which helps make seeing things in detail simple so you don't strain your eyes. A glass prism is used to bend light and make a rainbow out of white light. Used to gather and focus light. http://www.astronomynotes.com/telescop/s5.htm -Different Kinds of Telescopes Resources: http://www.kidsastronomy.com/telescopesB.htm -Telescope Types http://members.shaw.ca/quadibloc/science/opt02.htm -Types of Telescopes When people want to see objects in space that the human eye is not able to see we use a telescope. Some telescopes are more powerful than others so you would use a strong one to see things farther away. Astrologists use telescopes to learn more about the universe . We even put telescopes in space to inspect our universe for problems or learn more about the planets/ galaxies. http://imagine.gsfc.nasa.gov/docs/science/how_l1/xray_telescopes.html -Introduction to the X ray Telescope First picture of the sun taken by an X ray telescope http://astrology.alisonmoroney.com/l_astrologers.html -Famous Astrologists The planets in our Solar System Astrology is the study of the universe so an astrologist is a person that studies the universe. This relates to the telescope because they use that to make huge discoveries that changed our knowledge of our galaxy. As you already know there have been billions of Astrologists on this planet, but here are some of the more popular names. Maybe you already know some of them. Pythagoras (580- 500 B.C.) ~A Greek philosopher, astrologists, musician, religious inventor, and mathematitian. Believed that all the planets were all sphere and all revolved around a central point. His way of thinking was different then you could imagine. Aristotle (384- 322 B.C.) ~Believed that the world was sphereical and much smaller than the stars. Also belived that all matter was composed up of four elements: fire, earth air, water and aether( was said to make up celestial bodies).

Proved that the universe is expanding with the Hubble law. Proced Einstein wrong (Einstein said that space was curved by gravity, which meant that it was able to move in or outwards freely, but Hubble pointed out that it the universe stays still though it does expand.) Galileo Galilei (1564- 1642 A.D.)- Improved the design of the telescope in 1609 which was 20 times stronger than the first made by Leppershey. He discovered that there was craters in the moon with, stars in the milky way, the four largest satellites of Jupiter, and the phases of Venus. Hans Lippershey (1570- 1619)- The inventor of the telescope. Although many say they were the first to invent such a thing, Hans was the first person documented that made one. He made quite a few binocular telescopes for the State general in 1608. By having telescopes we have learned so much more about our solar system as well as others. This helps us understand more about are existance and about things beyond ourselves. It is truly part of our experience here on Earth. When we observe space, we can find out if we are in danger. For instance if there's a meteor coming straight for us we'll know. The universe is an insanely diverse place which we should know about, not just for scientific reasons but because we should want to. When we admire all the many things space brings to us we truly realize it is out of this world! By:Mila Menna Pretty simple: Put your eye in the finderscope eyepeice to view whatever you want to see. Set up the telescope to face what you'd like to look at. Use the focuser to make the image clearer and you're set! ~NASA had trouble launching the Hubble Space Telescope due to their financial standings. It was launched in the year 1990, after 7 years delay and it was over their budget limit of $2 billion. ~You should never look at the sun while using a telescope, saying as it amplifies the picture. ~The Hubble telescope was first to find out how old our universe is; it's said to be 13 to fourteen billion years old! ~Most of the famous astronomers on my list are mathematitians, philosophers, musicians, and/ or scientsist. Hmmmm..... The Hubble Space Telescope- A large, optical telescope that was brought into space by a space shuttle in 1990. It was named after Edwin Hubble, the astrologist. Supposed to last five more years. Costs $2.5 billion US dollars. Takes beautiful photographs of areas within its range. Moves 7.5km/ hr. http://www.space.com/6716-major-space-telescopes.htmlFull transcript
-Important Telescopes in Space Important Telescopes In Space Chandra X-Ray Space Observatory- An X ray telescope that is 100 times stronger than any other. Launched in 1999. Named after an astrophysist Subrahmanyan Chandrasekhar. Mission was only supposed to last five years, but elapsed into thirteen. Every few years astronauts check up on space telescopes and replace the nessecary parts for it to procede working. Every space telescope has a mission. Once it has completed the mission and there is nothing left for it to do the telescope is done. Astronauts put special gear onto the telescope way before its mission/ death is near. Telescopes are constantly monitored by the company that sent it up so they will know when it is done running if for some reason it stops which it shouldn't. After the mission is done or the telescope is not running properly the company will send up a robotic spacecraft to attach itself to the telescope. It is then brought down to Earth where the company stores it away or does what they want with it. Some are used in museums. So far there has not been a case where the telescope has just died up in space. Thhis is because it is looked after regularly. when parts need changing they send people up to do that. Definition of a Telescope An Instrument that is used to see parts of outer space that the human eye is not strong enough to view. All telescopes are able to work on Earth but some work better in space. All telescopes that work better in space are able to detect and collect different type of electromagnetic (EM) radiation. http://www.lbl.gov/MicroWorlds/ALSTool/EMSpec/ -Electromagnetic Radiation Telescopes monitor high amounts of radiation in space The Spitzer Space Telescope- Uses infared radiation to detect ratiated parts of space. Sent into space in 2003. Costs $720 million US dollars. Must be only a few degrees above absolute zero to work, this is because it is constantly around heated objects like the sun and could get burned if otherwise. http://www.guide-to-astronomy.narod.ru/scientists_and_astronomers/pythagoras.html -Pythagoras !!Thanks for watching my presentation!!
Electromagnetic radiation is produced from the movement of radiating electrically charged particles. These particles are floating through empty space. This includes gamma rays, infared, ultra violet light, x ray, and radio waves. All of these sources are heated and produce a great amount of energy. There is a chart called the Electromagnetic spectrum that states all objects with that cause electromagnetic radiation. Huh? What is Electromagnetic Radiation? How it's Made: Modern Reflector Telescope
