Mysterious golden orb found at bottom of ocean - and scientists have no idea what it is

Scientists have found a golden orb at the bottom of the ocean - and they admit they have no idea what it is.

Researchers operating a remotely operated vehicle (ROV) spotted the shiny mystery 3.2km deep off the coast of Alaska on 30 August.

A team from the U.S. government's NOAA Ocean Exploration department were left confused and excited by the sighting.

In footage from the find, a member of the Seascape Alaska 5 expedition crew is heard to say "it's like the beginning of a horror movie", while another suggests "I'm pretty sure this is how the first episode of the X-Files started."

Upon spotting the orb, the team make suggestions on what it could be, including a yellow hat, a face, an egg casing or dead sponge.

One researcher says: "It's almost like it was a face and whatever it was on it fell off."

Another says: "It's definitely got a big old hole in it, so something tried to get in or get out."

Ultimately, the team decided to suck the specimen up with a special collection pipe and take it to a ship-based laboratory.

Emily Crum, of NOAA, says the "orb" was successfully recovered and taken to NOAA Ship Okeanos Explorer.

Emily explained Tuesday (5 Sep): "I just received confirmation from the expedition coordinator on the ship that the orb remains a mystery.

"Sounds as if they won't learn more until after the expedition is over and they can take the specimen into a full lab setting."

NOAA Ocean Exploration's mission is set to last until 16 September.

They explain: "During the expedition, the team will work to fill gaps in our understanding of the region by conducting focused mapping and remotely operated vehicle operations in waters deeper than 200 metres (656 feet)."
