DIY Home Radio Telescope: Capture Cosmic Hydrogen Signals
A new DIY radio telescope design allows amateur astronomers to observe cosmic phenomena using accessible components like a 1-meter satellite dish and a Raspberry Pi. Detailed in a paper by Jack Phelps, this setup focuses on the 21-cm hydrogen line, crucial for studying galactic structures and dark matter. The project is affordable and opens up the possibility of observing not just hydrogen clouds, but also the sun, Jupiter, and other celestial phenomena, making radio astronomy more accessible to hobbyists.
