In honor of Halloween, NASA decided to release a playlist of creepy sounds collected from across the solar system. The playlist is embedded below.
There’s no atmosphere or other way of carrying sound waves in outer space, but the instruments aboard NASA’s various spacecraft can capture radio emissions. Those radio emissions are then sent back to Earth and converted into sound waves. The playlist includes the “roar” of Jupiter from the Juno spacecraft as it entered the planet’s magnetosphere. The sound captured reflected the collision of stellar wind and Jupiter’s magnetosphere.
The playlist consists of sounds collected from Jupiter’s largest moon, Ganymede. In 1996, NASA’s Galileo spacecraft collected radio signals from the moon as it made its first ever flyby. There are also sounds captured by the recently departed Cassini spacecraft from its many missions to Saturn. These include sounds from a giant thunderstorm during one of Cassini’s close dives into the planet’s rings. The playlist also features interstellar sounds collected by the Voyager spacecraft and up-close and personal visit with the comet Tempel 1 by the Stardust spacecraft in 2011.
This playlist is probably the scariest thing you’ll encounter this Halloween.
