Radio Astronomy

Listening to the Universe

Amateur radio astronomy projects — from hydrogen line observations to solar monitoring, pulsar timing, and Jupiter storm detection.

1420 MHz

Hydrogen Line

Mapping galactic structure by observing neutral hydrogen emission at 1420.405 MHz — the most accessible radio astronomy target for amateurs.

10–300 MHz

Solar Radio Bursts

Monitoring Type II and Type III solar radio bursts associated with flares and coronal mass ejections using simple wideband receivers.

20.1 MHz

Jupiter Storms

Detecting Jovian decametric radio storms generated by plasma interactions between Io and Jupiter's magnetosphere — predictable and detectable with a simple dipole.
