The Sound of Jupiter

NASA’s Juno spacecraft has crossed the boundary of Jupiter’s immense magnetic field. Juno’s Waves instrument recorded the encounter with the bow shock over the course of about two hours on June 24, 2016.

Bow shock is where the supersonic solar wind is heated and slowed by Jupiter’s magnetosphere. It is analogous to a sonic boom on Earth. The next day, June 25, 2016, the Waves instrument witnessed the crossing of the magnetopause. Trapped continuum radiation refers to waves trapped in a low-density cavity in Jupiter’s magnetosphere.

  1. For your possible interest – Luís, the following is a New Zealand choral group dedicated to mostly (but not only) sacral music and I thought they may provide an interesting counterpoint to your own excellent Portuguese choristers (though I suspect “counterpoint” be be the wrong choice of word). I would be interested in your reaction to their efforts, their being from such a ‘new’, and antipodean country so far away:

  2. Oh yes indeed, I am from there. A brother of mine still lives there and saw them recently (I now live in Perth Australia). He sings in a local choir.
