Unexplained ‘Woman’s Voice’ Recorded by NASA in Pacific Remains a Mystery
A strange sound, named ‘Julia’, was detected by the NOAA in 1999 from the Pacific Ocean. Theories have ranged from drifting icebergs to alien vessels, but the actual source is still uncertain.
A peculiar and eerie sound emerging from the deep Pacific Ocean has continued to baffle scientists for decades. Often described as similar to a ‘woman’s voice’, the unusual sound was first picked up in 1999 by the National Oceanic and Atmospheric Administration (NOAA), and its origin remains entirely unidentified.
Despite thorough attempts to determine the origin, NOAA experts were only able to trace it to a region in the Pacific between Bransfield Strait and Cape Adare. The sound, which lasted nearly three minutes, was detected from more than 3,000 miles away.
The sound, named ‘Julia’, had a distinctly haunting tone—many listeners said it resembled a woman humming softly. But even after 25 years, its true source remains a mystery, according to LADbible.
Bransfield Strait and Cape Adare are not adjacent regions, but are instead separated by hundreds of kilometres.
As no conclusive scientific theory was available at the time, several individuals came up with eerie conspiracy theories about its origin.
Some speculated it might be an alien spacecraft navigating underwater.
According to a Reddit post, during the same period the sound was recorded, NASA’s Apollo 33A5 satellite allegedly captured an image of a massive shadow moving through the southwestern part of Cape Cadre, around the same time the sound was picked up.
Many, however, remain doubtful of the extraterrestrial angle. One user wrote: “Not really… if it’s genuine, this creature hasn’t tried to harm us or create problems by coming near any ships. So honestly, nothing changes even if it’s true. Sailing in the ocean will still be the same.”
Another noted: “Actually, there are quite a few examples of unidentified loud noises like this, and each one ends up with some crazy conspiracy theory attached. That’s just how the Internet works.”
NOAA had earlier explained: “This sound was captured on March 1, 1999, via the eastern equatorial Pacific autonomous hydrophone array. The most probable source of the sound referred to as ‘Julia’ is a huge iceberg that ran aground near Antarctica. Given the ambiguity in the azimuth direction of arrival, the origin could lie between Bransfield Straits and Cape Adare, with the likely origin time being 1999 JD60 21:05 GMT.”
