SPACE SOUNDS

SPACE SOUNDS

The beat of the sun

Helioseismology “listen” to the Sun using a unit aboard the SOHO spacecraft.

Rings of Saturn

Saturn is the least dense of the planets: its density is 0.7 – less than that of water.

Magnetosphere of Ganymede

Recorded by NASA’s Gallileo spacecraft, these sounds show that the solar system’s largest moon has a magnetosphere that shields it from Jupiter’s magnetic influence.

Jupiter's magnetosphere

Remnants of the big bang

Radio telescopes received these sounds from a completely black body. Scientists suggest that these are the remains of a big bang.

Pulsar PRS B0329+54

This pulsar is one of the best known and also one of the first to be discovered. It has a period of 715 milliseconds, rotating 1.4 times per second.

Radar echo from the surface of Titan

This recording was made by converting into audible sounds part of the radar echo received by Huygens during the last kilometers of his descent to Titan. As it approached the ground, the intensity increased. Scientists will use the intensity of the echo to reason about the nature of the surface.

Accelerating through the fog of Titan

This recording is a laboratory reconstruction of the sounds heard through Huygens microphones. Several samples taken at different times during the descent are combined together to give a realistic reproduction of what a traveler aboard the Huygens would have heard during one minute of descent through Titan’s atmosphere.

Black hole GRS 1915+105

A theoretical astronomical object formed at the moment of the destruction of a massive star. Black holes are the evolutionary end points of stars at least 10 or 15 times more massive than the Sun.

Electromagnetic activity near Io during the I31 program

The soundtrack demonstrates the intensity of the disturbance of the electromagnetic field with a sharp rise and a sudden drop in electron density near the north pole of Io. The researchers translated the electromagnetic waves in the plasma near Io into the “language” of sound. It is the result of studies of the thin charged shell around Io using Galileo equipment, during its close flyby of the north pole on August 6, 2001. The place where the noise increases a lot is the area where Galileo traverses the paths of moving electrons along the magnetic field lines between Io and Jupiter.

Electromagnetic activity near Io during the I32 program

This soundtrack demonstrates the disturbance of the electromagnetic field near the south pole of Io. These data were obtained during Galileo’s flyby of the South Pole on October 16, 2001.
