Mysterious golden orb discovered on the ocean floor near Alaska is identified over 2 years later
Ahh! The mystery of the unidentified golden object discovered on the ocean floor off Alaska’s Pacific Coast in 2023 has been solved.
Although scientists often encounter alien organisms in the deep sea, these mysteries are usually solved quickly as experts compare notes and information. But even after a week, researchers were unable to determine whether the golden orb belonged to a known species, represented a new species, or was an unknown life stage of a documented species. The surprising discovery quickly attracted the attention of the scientific community and the public.
“Isn’t the deep sea delightfully strange?” Sam Candio, a National Oceanic and Atmospheric Administration scientist who participated in the expedition, said: September 2023 declaration. “While it’s a bit embarrassing to be stunned by this finding, it’s a reminder of how little we know about our own planet.”
The smooth, metallic-looking drop looked like a treasure treacherous crab from disney Moana He would hoard it. Was it a dead sponge or an egg carton? Something extraterrestrial?
None of the above. This week at NOAA researchers confirmed The golden orb was part of a giant deep-sea anemone.
Here’s what we know.
The approximately 4-inch object was discovered clinging to a rock among white sea sponges
In August 2023, NOAA Ocean Exploration, a federal program dedicated to exploring the unknown depths of the ocean, embarked on a three-week cruise in the Gulf of Alaska. The team spotted a perforated, shiny, golden orb clinging to a rock among white sea sponges more than 3 kilometers below the surface.

The rock itself was too large to pick up, so the researchers used a suction sampler to carefully collect the golden object.
It was then sent to the Smithsonian National Museum of Natural History for further research and analysis.
Scientists eventually determined that the approximately 4-inch golden object was a remnant of dead cells that formed at the base of a giant sea anemone known as Relicanthus daphneae. It was the part of the anemone that stuck to the rocks.
Researchers with specific expertise needed to pool their knowledge

Ultimately, researchers had to analyze both the physical structure and DNA of the sphere. NOAA’s statement as a “complex endeavor.”
“We study hundreds of different samples, and I suspected our routine processes would clarify the mystery,” said Allen Collins, a zoologist and director of NOAA Fisheries National Systematics Laboratory. “But this turned out to be a special case that required the focused effort and expertise of several different individuals. This was a complex mystery that required morphological, genetic, deep-sea and bioinformatics expertise to solve.”
Where do we go from here
While researchers have solved the mystery of the golden sphere, Earth’s deep oceans still hold many mysteries, NOAA said.
“In deep ocean exploration, we often encounter fascinating mysteries like the ‘golden sphere.’ “With advanced techniques like DNA sequencing, we are able to solve more and more,” said Capt. William Mowitt, NOAA Acting Director of Ocean Exploration. “That’s why we continue to explore to unlock the secrets of the deep and better understand how the oceans and their resources can spur economic growth, strengthen our national security, and sustain our planet.”
