Sounds of Saturn:
Hear Radio Emissions of
a Planet and Its Moon
Cassini's final orbits revealed
a powerful interaction
between Saturn and
the moon Enceladus.
Scientists observed plasma waves
moving in a circuit
from planet to moon.
The waves were converted
into audio we can hear.
[eerie, high-pitched
sounds like wind]
Time was compressed from 16
minutes to 28.5 seconds,
and wave frequency was
decreased by a factor of 5.
Cassini captured the data
on September 2, 2017,
two weeks before the spacecraft
plunged into Saturn's
atmosphere.
