Optical Telescopes Part I
Posted in Telescopes on October 28th, 2010 by admin
The beginning of modern Astronomy is often linked to Galileo building his first telescope in 1609 — roughly 400 years ago! While he was not the first person to use a telescope, Galileo made many fascinating discoveries, ultimately revealing that the Earth orbits the sun.
This video showcases the Zenith Telescope, built by Troughton & Simms in London, England circa 1872. Surveyors used this telescope to mark the boundary between Canada and the United States along the 49th parallel in western Canada.

Reissued in HD. Bad Astronomer Phil Plait shows us the ropes on the Red Planet. His amazing book “Death from the Skies,” is now available in paperback via Amazon.com.
Science video on Mars presenting VRMars Astronomy Software. The video shows panoramas and images, including the “Whale” panorama and Martian sunset, taken by NASA’s Mars Rover Spirit during the Mars Rover Mission. The video was created with the use of virtual reality science software VRMars-Spirit – The Red Planet Mars 3D, released by Sciterian Technologies, and powered by the technology VRPresents that gives an impression of being on the surface of Mars. Great astronomy video for those interested in science, and space exploration enthusiasts. Get this astronomy program at www.vrmars.com or www.vrmars.com/VRMars-Spirit-The-Red-Planet-Mars-3D.htm , and enjoy roving Mars. See the planet like you were one of the Mars Rovers at www.vrplanet.com .

The Sun and stars emits radio waves — not just visible and infrared light. In the 1930s, Karl Jansky built the first devise to “listen” to the sun, collecting radio waves from far off stars and focusing them onto a detector. This invention provided astronomers with a completely different view of the Universe — prompting the discovery of radio stars, quasars, and black holes.
The new WorldWide Telescope enables space ex[ploration from the desktop. It stitches together imagery from
