These 8 sounds and signals are subjects of constant speculation between conspiracy theorists and scientists alike, but it’s possible that we’ll never know their origin or meaning...
Several times during 1997, a sound reverberated through the Pacific Ocean that has been a mystery to science ever since. Dubbed “the Bloop”, the sound rises rapidly in frequency over one minute and was loud enough to be picked up by multiple sensors located up to 5,000km apart. These underwater listening devices were put in place in an area known as the “deep sound channel” during the Cold War to detect and track Soviet submarines, and are now used by the National Oceanic and Atmospheric Administration to monitor natural phenomena.
The NOAA says there’s no way the sound was man-made, and while it does sort of resemble a sound made by a living creature, there’s no whale in the world that’s large enough to produce a sound of such volume – not even gigantic blue whales.
2. The Hum
All over the world in places like Hawaii, New Mexico and England, every now and then people turn to each other and say, “What’s that humming sound?” It’s described as an irritating, persistent low-frequency sound that resembles the sound of a distant diesel engine idling and can often be felt as vibrations in the body. According to people who have heard it, microphones just can’t seem to accurately capture this noise. It’s loudest indoors, at night and on weekends.
On Big Island in Hawaii, the noise is attributed to volcanic activity, but the same certainly can’t be said in Kent, England or Taos, New Mexico.
3. Bizarre Booms
“Mistpouffers” – it’s a funny name for a series of bizarre booms that have been heard in waterfront communities ranging from Bangladesh to the Netherlands, typically described as a cannon sound or extremely loud thunder despite the absence of clouds in the sky. It’s frequently heard on calm summer days in the Bay of Fundy, Canada and has also been reported in Italy, Ireland, India, Japan, the Philippines, Ireland and in several U.S. States. These booms are no modern invention – the Iroquois explained similar noises to early white settlers as the sound of the Great Spirit continuing to shape the earth.
In 1978, a boom heard on Bell Island off Newfoundland in Canada was powerful enough to damage homes. While some may still believe that it was caused by supernatural phenomena and a recent History Channel special questioned whether secret electromagnetic pulse weapons tests could be the culprit, the cause is still a mystery.
4. The ‘Slow Down’ Sound
Recorded on May 19th, 1997 – the same year as ‘The Bloop’ – this unexplained sound is seven minutes long, slowly descending in frequency toward the end. Known as the ‘Slow Down’ sound, it was loud enough to be heard on three sensors at a range of nearly 2,000km. Nothing like it has been heard ever since.
During the Cold War, as Soviet Navy ballistic missile submarines patrolled the North Atlantic and Arctic Ocean, they kept hearing the strangest sounds: what they described as “quacking”, the Russian version of our own onomatopeotic “ribbit” of a frog. The sounds were heard whenever the subs passed certain areas of the sea and seemed to be coming from a moving underwater object. However, nothing registered on sonar.
The Soviets believed at the time that they were hearing some kind of secret U.S. Technology and interpreted the sounds as a somewhat frightening threat. Today, scientists believe the sounds may have come from marine life like giant squid, which – lacking rigid internal skeletons – might not show up on sonar.
6. The Spooky Sounds of Saturn’s Rings
They’re eerie and otherworldly, exactly the kinds of bizarre noises you would expect to hear in a sci-fi film – but they’re actually real recordings from another planet. The Cassini spacecraft began detecting these auroral radio emissions from Saturn’s atmosphere in 2002, which have natural rising and falling tones similar to those emitted by Earth.
7. The UVB-76 Buzzer
It seems like a mystery worthy of LOST – a strange repeating radio signal from Russia, punctuated by occasional cryptic messages in Russian. Short, monotonous buzzing tones have been emitted 25 times per minute, 24 hours a day since 1982, and nobody knows exactly why. Perhaps it’s used to transmit encoded messages to spies, or signal the status of some undercover military installation. Or, maybe it’s just related to high-frequency Doppler weather radar.
The voice messages transmitted by this signal, which have occurred only three times in 1997, 2002 and 2006, have all been numerical in nature. One features a Russian male voice saying “”Ya ? UVB-76. 18008. BROMAL: Boris, Roman, Olga, Mikhail, Anna, Larisa. 742, 799, 14.”
8. The ‘Wow’ Signal
Did aliens try to contact us with an interstellar signal detected in 1977? The strong narrowband radio signal picked up by The Big Ear telescope of Ohio State University lasted for a total of 72 seconds and matched the expected signature of an interstellar signal, prompting Dr. Jerry Ehman to circle the signal on a printout and write “Wow!” beside it.

It kind of reminds me of flashes I've seen that would light up valleys at night. I remember one time I was out 4 wheeling in the middle of nowhere in a valley then all of a sudden there was a extremely bright flash for about 1 or 2 seconds that lit everything up completely.
That has only happened a few times, but not just to me.
