A DISCOVERY Channel treasure hunter has made an “astonishing” discovery in the depths of the Bermuda Triangle that he believes is evidence of aliens landing on Earth.

Darrell Miklos uses secret maps created by his ex-NASA astronaut pal Gordon Cooper to unearth shipwrecks in the briny deep.

But during one of these trawls, intrepid explorer Miklos stumbled across huge mysterious structures that he thinks could change how we view our place in the universe forever.

The huge unidentified submerged “spaceship” is covered in 15 unusual “protrusions” — which Miklos describes as “unlike anything I have ever seen.”

Miklos, who will show off his other-worldly find on his Discovery Channel show Cooper’s Treasure, said: “It was also something that was completely different from anything that I’ve seen that was made by nature.”

The mystery objects were found lying on the seabed near the Bahamas — within the notorious 1.3 million km watery grave known as the Bermuda Triangle.

It is the scene of countless strange disappearances of planes and ships — attached to which are curious tales that some discredit as myth but others say point to extra-terrestrial or even paranormal happenings.

Veteran diver Miklos made his mammoth discovery during a hunt for the wreck of English ships related to the 16th century British sea captain Sir Francis Drake.

But using maps designed in the 1960s by astronaut Cooper, Miklos detected more than 100 magnetic “anomalies” at an undisclosed location deep in the Caribbean waters.

He claims Cooper gave him the detailed maps after he was diagnosed with Parkinson’s, before his death in 2004 at the age of 77.

In the first season of the show Miklos and his team used them to track down a centuries-old anchor thought to come from one of Christopher Columbus’ ships.

Cooper’s maps also led Miklos to dozens of other significant ship wrecks across the Caribbean worth millions.

Describing his approach to his latest find, Miklos said: “I was trying to identify shipwreck material based on one of the anomaly readings on Gordon’s charts when I noticed something that stuck out, that shocked me.”

He said the object has the appearance of a “battleship” with a steep wall, from which five protruding arms stick out like cannons.

Using special breathing apparatus to reach the 300-foot (91.5-meter)-deep “spaceship,” Miklos said he and his fellow divers noticed that it did not appear to be man-made.

And the fact it was covered in thick coral suggested the object — if it landed there from beyond our planet — did so hundreds if not thousands of years ago.

Miklos added: “Certainly nothing I’ve ever seen based on my experience — and I have years of experience at doing this, we’ve identified multiple different types of shipwreck material — this doesn’t match or look anything like that.”

Looking back at the Cooper charts, Miklos came across a puzzling note left by the former spaceman at the site of the structure — “unidentified object.”

Now, Miklos wants to investigate the mysterious site further — despite the risk he faces of being dubbed an alien conspiracy theorist.(SD-Agencies)
