A mysterious “golden orb” discovered deep beneath the ocean off Alaska’s coast has finally been identified by scientists after puzzling researchers for more than two years.
The unusual object was first found in 2023 during a deep-sea expedition by the National Oceanic and Atmospheric Administration (NOAA), more than two miles below the surface in the Gulf of Alaska.
A Strange Discovery in the Deep Ocean
Scientists aboard NOAA’s exploration vessel used a remotely operated vehicle to examine the ocean floor when they spotted a golden, dome-shaped object with a small hole, attached to a rock.
At the time, researchers were unsure what they had found. Early theories ranged from:
- An unknown species
- A deep-sea egg casing
- A type of sponge or coral
The object’s unusual appearance and lack of clear biological features made identification difficult, even for experienced marine scientists.
Years-Long Investigation Solves the Mystery
After extensive analysis involving multiple institutions, including the Smithsonian National Museum of Natural History, scientists have now confirmed the orb’s identity.
Researchers determined that the object is a remnant of a rare deep-sea anemone, known as Relicanthus daphneae.
Specifically, the “golden orb” is believed to be part of the structure that once anchored the organism to the ocean floor, composed of biological material left behind after the animal detached or died.
Why It Was So Hard to Identify
Scientists say the discovery proved unusually challenging because the object did not resemble a typical marine organism.
- It lacked visible features like tentacles or symmetry
- It appeared smooth and “fleshy” with a single opening
- It was found in an extreme environment more than 3,000 meters deep
The case required a combination of genetic testing, microscopic analysis, and collaboration across scientific disciplines to confirm its origin.
