Today we hit "cosmic shores" with a surfboard for Tuesday's blog to experience Ganymede's epic chorus waves!
A recent discovery at Ganymede happened to perfectly align with a symphonic gesture which I could not ignore. Scientists have observed chorus waves at Ganymede that are a million times stronger than at Jupiter. And let's face it, it's not often Jupiter gets upstaged.
Chorus waves are energetic electrons that become trapped in the magnetosphere and spiral along magnetic field lines generating waves in the plasma. So, with a discovery that straddles both the world of music and science, this had to be a dramatic stage moment for Ganymede.

Also, this passage of music draws attention to Ganymedes's other incredible scientific activity — Magnetic reconnection; which happens in many astrophysical environments inside and beyond the solar system.

Magnetic Reconnection
In 1995, the Galileo spacecraft flew straight through an explosive event at Ganynemede; a phenomenon called Magnetic reconnection magnetic reconnection. Galileo saw huge strings of plasma passing between Jupiter and Ganymede.
Reconnection can abruptly convert the energy stored in magnetic fields to energy in charged particles and power diverse phenomena such as solar and stellar flares, magnetic storms and aurorae.
Unlike Monday's blog, where the musical atmosphere was a lilting lullaby, Tuesday, the cosmic womb, awakes by the sound of dramatic hits from timpani, leading to the "chorus waves" event and signals the end of the science chapter.
Tomorrow we become transported in time to explore Ganymede's other significant story and reconnect with A LEGEND!
