Outer space is a vast mystery to us tiny humans here on earth. But every once in a while, we get a glimpse of what it's really like out there. This list is full of creepy space noises that have been recorded over the past several decades. Most of them are naturally-occurring phenomena produced by atmospheric changes or changes in electromagnetic fields, but some of them have yet to be explained - and yes, it is possible that some of them come from extraterrestrial intelligent life.These spooky space sounds just might be the key to communicating with whomever might be out there beyond our solar system...
Radio Emissions from Saturn
NASA's Cassini spacecraft began detecting radio emissions from Saturn in 2002, when the craft was first approaching the planet. According to NASA, these radio waves come from Saturn's poles, and are linked to Saturn's aurora - the same phenomenon as the aurora borealis here on earth. The sounds in the video have been sped up and adjusted so that they are within the frequency of human hearing.
"Outer Space Music" from the Far Side of the Moon
In 2016, NASA released to the public the sounds that Apollo 10 astronauts heard while on the far side of the moon over four decades ago. The astronauts would have been out of radio contact with Earth on the far side of the moon, leading some (including astronaut Al Worden) to believe that these sounds came from an extraterrestrial source. NASA, however, has dismissed the noises as radio interference between the lunar module and the command module of the mission.
The Heartbeat of a Black Hole
Binary star system GRS 1915-105 consists of a black hole and a star that constantly feeds it. An MIT professor took X-ray data from the black hole and translated it into sound. Sped up, the track becomes an eerie, heartbeat-like pattern, which is the sound of the black hole repeatedly spewing out matter.
A Singing Comet
The European Space Agency's Rosetta spacecraft recorded a strange "song" from a comet in 2014. Scientists think the sounds were produced by oscillations in the comet's magnetic field. The audio has been adjusted to bring the sounds within the range of human hearing.
