Parker: Sounds of the Solar Wind
Explanation: What does the solar wind sound like? A
wind of fast moving particles blows out from
our Sun, and although
space transmits sound poorly, particle impact and variable-field data from NASA's near-Sun
Parker Solar Probe is being translated into
sound. The disarming audio track of the featured video recounts several of
these reverberations, including spooky-sounding
Langmuir Waves (heard first), hurricane-sounding
Whistler Mode Waves (heard next), and hard-to-describe
Dispersive Chirping Waves (heard last). Also impressive is the video's time-lapse visual track which shows
Parker's view to the side of its sun shield, and where the planets
Earth,
Jupiter,
Mercury and
Venus appear in succession, interspersed with bursts of
powerful cosmic rays impacting the imager. The nature of the solar wind near Mercury is
surprisingly different from near the Earth, and
much study is underway to better understand the differences.
