NASA released "creepy" space sounds last week on its website just in time for Halloween.
The sounds were made when engineers converted captured radio waves in space into sound waves, NASA said on its website. The sounds include the spacecraft Juno passing through Jupiter's magnetic field in 2016, plasma waves from the Van Allen probes, Saturn's radio emissions captured by Cassini, and Galileo's first flyby of Jupiter's largest moon, Ganymede.
One of the sounds NASA released came from NASA's Stardust spacecraft while it was pelted by dust particles and small rocks from the comet Tempel 1 in 2011.
Science Alert described the recordings as sounds "from cacophonic plasma waves to eerie Saturn radio emissions and whispers caught off Jupiter's moons, this playlist of space sounds is weird, beautiful, and a little unpleasant at times."
NASA described Juno's recording of Jupiter on June 24, 2016, as a "roar" over two hours. The plasma waves heard from the Van Allen probes, like a "roaring ocean surf," can be heard across space, the space agency said.
Galileo's audio track during Ganymede's flyby represented data from the spacecraft's Plasma Wave Experiment instrument designed to add sound to radio signals to better understand the signal, called "data sonification," NASA noted.
Saturn's radio waves are closely related to the auroras near the poles of the planet, which are similar to Earth's northern and southern lights, NASA said.
Many on social media marveled over the space sounds.
