If you didn’t know any better, you would likely think that space is a relatively quiet place. However, that couldn’t be any further from the truth.

On the contrary, space is very loud, with various sounds and signals being detected throughout. While many of these sounds can be explained as the sounds of shifting planets, some of these sounds are unexplainable signals that are quite frankly terrifying.

1. WOW signal

First detected in 1977, at the Big Ear Radio Observatory in Ohio, the WOW signal was initially thought to be aliens. While various theories have been thrown around, nothing has ever been confirmed. The most recent theory is that the sound could have been emitted from Comet 266P/Christenson because the signals emitted from the comet have been matched. Even with that being said, there are still those who disagree with this theory.

2. Venus signal.

The Venus signal was detected during a recent pass when NASA’s Parker Solar Probe flew by Venus and picked up some strange radio signals. They heard them for seven minutes, and they began working to try to understand what had caused the sounds. While many people do believe them to be the alien origin, they were found to match the signal that would be caused by the gases on Venus.

3. Space roar.

When you are in space, no one can hear you scream. The reason for this is that space is composed of radio waves which are quite loud. When scientists looked at the ‘space roar’ back in 2006, it was six times louder than what they had expected. The fact that it’s so loud has astonished scientists, who say that the signal is so loud and coming from so many directions, that it cannot be one object.

4. The Lone Survivor

In 2003, astronomers involved in a search for extraterrestrial intelligence detected several unexplainable signals in space. When they tried to reconfirm their findings and finished analyzing the data, they found that all of them had disappeared. Well, except for one that continued to get stronger. To this day, the source of the signal remains a mystery.

5. Milky Way radio burst.

In the past few years, scientists have discovered a series of flashes of cosmic radio waves that are referred to as fast radio bursts (FRBs.) The sounds were coming from a galaxy that is over 3 billion light-years away. The even stranger fact is that the host galaxy is a star-forming dwarf system, and this fact is what keeps scientists puzzled.

6. BLC-1

In 2019, a Ph.D. student from the University of Sydney, Andrew Zic began observing a nearby star Proxima Centauri. While observing it, a strange signal was observed that is known as BLC1. After testing the signal, scientists explained the signal away by saying that it must be radio signals coming from Earth, however, not everyone is convinced.

7. Lorimer Burst

One of the first fast radio bursts was detected in 2007 and was discovered by a team led by Duncan Lorimer. What they found was an incredibly bright pulse, which was so bright that the scientists observing it didn’t believe it was real. When they began analyzing it, they found that it came from a galaxy billions of light-years away. Even stranger was the fact that whatever had produced it had to be capable of releasing as much energy as our Sun releases in 80 years. But, it was released in a millisecond.

8. Solar system exit.

Between the years 2012 and 2013, NASA’s Voyager 1 spacecraft sent signals that it picked up after passing through the end of our solar system and entering into deep space. The sound it recorded was anything but settling. It sounds as though something or someone is shrieking. I have linked a video below so you can listen.

9. Saturn’s Rings

Saturn is my favorite planet because its rings are beautiful. However, would you believe me if I told you that Saturn’s rings make a sound? In 217, the Cassini spacecraft picked up sounds from inside of Saturn’s rings. Not only do the rings make noises, but the noises are also extremely creepy.

10. Juno Picks Up Eerie Sounds from Jupiter’s Moon

During its flyby Jupiter’s moon, Juno recorded some strange noises. The resulting sounds were screeches, bleeps, and howls that will leave goosebumps on your skin. Not only that, but during the recording, there is an abrupt change in frequency that is unexplainably weird.

11. Signals Coming from the Heart of Our Galaxy

Earlier this year, astronomers from Australia detected strange radio signals from the center of the Milky Way. According to Ziteng Wang, a Ph.D. student working with the team, the strangest aspect of this signal is the fact that it is highly polarized. On top of that, the sound turns on and off irregularly, and as it stands, there is no known source for it.
