Radio Telescopes
Posted in Telescopes on July 15th, 2010 by admin
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.
This video features a model of the Algonquin Radio Observatory (ARO), located in Ontario’s Algonquin Provincial Park. In 1968, astronomers combined signals from the ARO with those from the Dominion Astrophysical Radio Observatory in Penticton, British Columbia forming a new instrument called a Long Baseline Interferometer.

How often do you get to see the moon this close up?? This is some footage I got last night, 9/8/08 of the moon. My Nexstar 8 telescope was magnifying the moon 120x, allowing the craters of the Northeastern and southeastern quadrants of the moon to be seen in detail. There was a cloud in front of the moon, however, I was still able to get some good shots.
