Mystery Golden Orb Found 2 Miles Deep Finally Identified

After three years of scientific detective work, researchers have finally identified a mysterious golden object found two miles beneath the Gulf of Alaska's surface.

The answer? Dead cells that once formed the base of a massive sea anemone, leaving behind a 4-inch glowing orb stuck to a rock on the seafloor.

Scientists discovered the puzzling sphere in 2023 during a research mission west of Prince of Wales Island. A remotely operated vehicle plucked it from the ocean floor aboard the NOAA Ship Okeanos Explorer, and experts immediately started scratching their heads.

Initial guesses ranged from an egg case to a dead marine sponge. But solving the mystery required a team effort from NOAA Fisheries and the Smithsonian National Museum of Natural History, using everything from DNA sequencing to deep-sea expertise.

"We work on hundreds of different samples and I suspected that our routine processes would clarify the mystery," said Allen Collins, a zoologist at NOAA Fisheries' National Systematics Laboratory. "But this turned into a special case that required focused efforts and expertise of several different individuals."

The discovery came from Seascape Alaska, an ambitious program mapping one of Earth's least-known frontiers. Right now, 61% of Alaska's waters remain unmapped territory, making each expedition a journey into the genuine unknown.

Why This Inspires

The golden orb mystery shows how much wonder still hides in our oceans. The sea anemone species that left this cellular calling card can grow tentacles stretching up to 7 feet long, a reminder that alien-like creatures thrive right here on Earth.

These mapping missions do more than satisfy curiosity. The work helped the U.S. State Department establish extended continental shelf claims in the High Arctic and Bering Sea in 2023, protecting American interests while advancing our understanding of ocean ecosystems.

And the discoveries keep coming. In 2024, the same program found a gas-emitting volcano-like structure rising 500 meters from the Arctic Ocean floor, proving that every dive brings new surprises.

"So often in deep ocean exploration, we find these captivating mysteries," said Capt. William Mowitt, acting director of NOAA Ocean Exploration. "This is why we keep exploring, to unlock the secrets of the deep and better understand how the ocean and its resources can drive economic growth, strengthen our national security, and sustain our planet."

The golden orb now rests in the Smithsonian's collection, a testament to human curiosity and the incredible creatures sharing our blue planet.
