Tools of Astronomy Song

Tools of Astronomy Song.Here is a song I created to help my 6th grade students study. I hope you enjoy. It's been 26 really long years No days of torture but he was bitter Galileo was forced to stay home Because he made better telescopes with more power La, la, la, the inquisition, la, la, la, not geocentric, la, la, la oh well, la, la, la Look at the sky tonight, tonight At observatories on top of the world Tonight, satellites, are dancing on edge of the atmosphere Telescopes could be reflecting, radio or refracting Making light, more bright, of the sky, tonight He saw that Jupiter had many moons Was able to see Saturn, Milky Way has many stars Surface of the moon was not so smooth Thanks Galileo Galilei La, la, la, whatever, la, la, la, heliocentric, la, la, la, oh well, la, la, la Look at the sky tonight, tonight At observatories on top of the world Tonight, satellites, are dancing on edge of the atmosphere Telescopes could be reflecting, radio or refracting Making light, more bright, of the sky, tonight You got me singing like Whoa, come on, ohh, it's all matter, whoa, everybody now, ohh Telescopes reflecting use mirrors Keep the light up and shoot it on down But refracting use convex lenses Focus the light to the eyepiece lens Radio detects low vibration Focus the waves from far outer space Satellites can see UV, x-rays Gamma rays in the atmosphere And a spectrograph breaks the light down and it Splits the colors to show what's around and Temperature and chemical <b>...</b>

Teach Astronomy - Reflecting Telescopes

refractor telescopes video






www.teachastronomy.com Essentially all modern telescopes used by research astronomers are reflecting telescopes. They use mirrors to bend, deflect, and focus light to form an image. The first reflecting telescope was perfected by Isaac Newton, and reflecting telescopes of larger and larger aperture have been produced ever since. Edwin Hubble discovered the distant nature of galaxies and the expansion of the universe using the largest reflecting telescope at the time just outside Los Angeles. For several decades the largest reflector was the 200-inch or 5-meter diameter telescope at Mount Palomar. The Russians built a 6-meter telescope in the 1970s. Currently the largest single mirror telescopes are just over 8-meters in diameter. The advantage of a reflecting telescope relative to a refractor is that the mirror can be very large and thin because the light is only reflected from the front surface. A reflector also reflects all the waves of light by equal amounts, and so the images that are formed have no chromatic aberration. The two slight disadvantages of reflecting telescopes are that the mirror's surface is exposed to the elements and must be occasionally recoated and the fact that since the light is focused in front of the mirror, some of the light must be blocked by a secondary or by a detector to gather the light.

Galileo and 400 Years of Telescopic Astronomy - book launch talk - PART 1

reflecting telescopes video






A fascinating talk by one of the authors about the astronomy book Galileo and 400 Years of Telescopic Astronomy by Peter Grego and David Mannion. Dr. Mannion gives an impassioned and absorbing account of the history of astronomy, scientific advances and how the use of the telescope changed our world - and indeed universal - view forever. The talk was filmed in Waterstones, Canterbury at the book launch there. Our kind gratitude to Waterstones and all the staff who helped facilitate a wonderful evening.
