Greetings, E.T. (Please Don’t Murder Us.)

On Nov. 16, 1974, a few hundred astronomers, government officials and other dignitaries gathered in the tropical forests of Puerto Rico’s northwest interior, a four-hour drive from San Juan. The occasion was a rechristening of the Arecibo Observatory, at the time the largest radio telescope in the world. The mammoth structure — an immense concrete-and-aluminum […]

via HACKADAY: See Satellites with a Simple Radio Telescope

Have you got a spare Dish Network antenna lying about? They’re not too hard to come by, either curbside on bulk waste day or perhaps even on Freecycle. If you can lay hands on one, you might want to try this fun radio telescope build. Now, don’t expect much from [Justin]’s minimalist build. After all, […]

Grote Reber Listens to Space: Out Of This World Hobbies at Eco Relics (Florida)

January is national hobby month, a time to acknowledge our interests that fall outside of our professions. Hobbyists and amateurs have reached the highest levels of human creativity, from backyard astronomers and garage chemists to Sunday painters and midnight scrawlers. Consider Grote Reber, for instance, an American original born in Wheaton, Illinois, in 1911. When […]

via HACKADAY: Junkyard Dish Mount Tracks Weather Satellites

There’s a magnificent constellation of spacecraft in orbit around Earth right now, many sending useful data back down to the surface in the clear, ready to be exploited. Trouble is, it often takes specialized equipment that can be a real budget buster. But with a well-stocked scrap bin, a few strategic eBay purchases, and a […]

via HACKADAY: Listen to the Sun, Saturn, and the Milky Way with Your Own Radio Telescope

Students from the Indian Institute of Science Education and Research combined a commercial satellite dish, a satellite finder and an Arduino, and produced a workable radio telescope. The satellite dish provides the LNB (low noise block) and the associated set-top box is used only for power. Their LNB employs an aluminum foil shield to block […]

via HACKADAY: The Tiny Radio Telescope

Radio telescopes are one of the more high-profile pieces of scientific apparatus. There is an excitement to stories of radio astronomers of old probing the mysteries of the Universe on winter nights in frigid cabins atop massive parabolas, even if nowadays their somewhat more fortunate successors do the same work from the comfort of their […]
