Here are selected samples of different types of radio noise detected by the Radio JOVE system.


S-Bursts (WCC Radio Telescope)

S-bursts (short bursts) have durations of a few thousandths to a few hundredths of a second and can occur at rates of tens of bursts per second. Groups of S-bursts sound like popcorn popping -- or like a handful of pebbles thrown onto a tin roof. S-bursts are often associated with the Io-B or Io-C source (sources that are influenced by the location of the Galilean moon Io).

L-Burst (University of Florida Radio Telescope)  

L-bursts (long bursts) last from a few tenths of a second to a few seconds and sound like ocean waves breaking up on a beach.

Mixed Io-C Activity (WCC Radio Telescope)  

On occasion the Jovian activity is a mix of L and S-bursts.


Solar Burst (WCC Radio Telescope)

Solar bursts typically last from half a minute to a couple of minutes and often sound like a rapid increase in the background noise (hissing noise) followed by a gradual decrease back to the original baseline level.

Galactic Background

Galactic Noise (University of Florida Radio Telescope)

Glactic Background Radio Noise is caused by relativistic electrons spiraling in the galactic magnetic field.
