via the RSGB: Asteroid named after radio amateur

The International Astronomical Union has named a celestial body after a radio amateur. Space physicist and radio amateur Asta Pellinen Wannberg, SM3UHV, is a professor at the Department of Physics at Umea University. She has made a ground-breaking effort to use scattering radar when studying meteors that are activated when small particles penetrate the atmosphere. […]

Totality-minus-6 months: Ten ways to get fired up for an all-American solar eclipse

Six months from today, millions of Americans will watch the sun darken during a rare coast-to-coast eclipse – and it’s not too early to get into the spirit of totality.

NASA discovers mysterious electron superhighway above Earth

Some electrons are speeding above Earth’s surface at nearly the speed of light, and NASA isn’t sure why. According to a new study, the tiny, charged particles were found accelerating to high speeds in an unexpected part of space, farther from Earth than previously realized. The region these fast electrons were found in, known as […]

via HACKADAY: Listening to Jupiter on a DIY Radio

If you want to get started with radio astronomy, Jupiter is one of the easiest celestial objects to hear from Earth. [Vasily Ivanenko] wanted to listen, and decided to build a modular radio receiver for the task. So far he’s written up six of the eight planned blog posts. The system uses an LNA, a […]

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 […]
