For two decades the Japanese VERA radio astronomy project has been gathering data to build up a 3D map of the position and velocity of objects revolving in our galaxy. The latest analysis indicates that the Earth is 2,000 light-years closer to the cent… Continue reading Earth is 2,000 light-years closer to galactic center than we thought
The HackRF is an exceptionally capable software defined radio (SDR) transceiver, but naturally you need to connect it to a computer to actually do anything with it. So the PortaPack was developed to turn it into a stand-alone device with the addition of a touchscreen LCD, a few buttons, and …read more

The National Radio Astronomy Observatory (NRAO) has announced a new addition to NASA’s upcoming moon-shot Artemis program. From the silent skies on the far side of the Moon, the DAPPER spacecraft will listen out for radio signals from the “Dark Ages” o… Continue reading Lunar orbiter to listen for radio signals from cosmic “Dark Ages”
Matt Blaze discusses (also here) an interesting mystery about a Cuban one-time-pad radio station, and a random number generator error that probably helped arrest a pair of Russian spies in the US.
