Moons of Mars
Mars has two moons, Phobos and Deimos, which are thought to be
captured asteroids. Both satellites were discovered in 1877 by Asaph
Hall and are named after the characters Phobos (panic/fear) and Deimos
(terror/dread) who, in Greek mythology, accompanied their father Ares,
god of war, into battle. Ares was known as Mars to the Romans.
Singing Comet
This was detected by Rosetta coming from Comet 67P/Churyumov-Gerasimenko. It is due to oscillations in the magnetic field in the comet’s environment.
The particles the comet is releasing into space are being electrically charged due to ionization.
The sounds of Neptune captured from the NASA Voyager.
This is the sound Jupiter emits via electromagnetic waves.
