Satellite Images Show Mysterious Nan Madol Ruins From a Brand-New Perspective

The ancient complex of Nan Madol on the island of Pohnpei in Micronesia has fascinated visitors for centuries. Now, thanks to satellite technology, researchers have captured the ruins from a perspective that's rarely seen.

As Yahoo 7 reports, the new aerial footage debuted on an episode of the Science Channel series What on Earth? In the recent installment, experts discussed Nan Madol, a chain of intricate, human-made islands that is sometimes called the "Venice of the Pacific" and is a UNESCO World Heritage Site. The name Nan Madol means "spaces between," a reference to the network of canals connecting the ruins.

The 100-odd blocky stone structures were built atop coral reefs in a lagoon off a remote island in the western Pacific Ocean. The walls of the artificial islands can reach up to 25 feet tall and are 17 feet thick in some parts. In total, the rocks that make up the site weigh nearly 827,000 tons. Archaeologists believe that portions of the city have been there for more than 1000 years, and that the site once served as the ceremonial, political, and residential hub for the native Saudeleur people. Little is known about how its builders were able to move such massive amounts of stone without levers, pulleys, or metal. 

Today, the Micronesian island of Pohnpei is home to 36,000 people, and even among locals, the landmark is notorious. Legends of spirits haunting the area have earned it the nickname "Ghost City." The ruins give off such an eerie vibe that H.P. Lovecraft used them as inspiration for the home of Cthulhu in a short story.

Take a Closer Look at the $17 Billion 'Holy Grail of Shipwrecks'

Feast your eyes on these new images of the treasure among the wreckage of the Spanish ship San José, often called the "holy grail of shipwrecks." When it sank on June 8, 1708, it was carrying gold, silver, jewels, and other precious cargo worth roughly $17 billion today. Now, Woods Hole Oceanographic Institution (WHOI) is revealing the major role it played in the 2015 expedition to find the San José.

The three-masted, 62-gun Spanish galleon exploded and sank at the hands of the British during the War of the Spanish Succession. It was carrying its riches to the Colombian city of Cartegena to finance the war. Archaeologists had been trying to find the San José for decades before it was finally located on November 27, 2015, during an expedition organized by Colombia, Maritime Archaeology Consultants (MAC), and WHOI. The multibillion-dollar treasure, which still sits nearly 2000 feet below the surface of the ocean near Cartegena, is just now being revealed.

WHOI's autonomous underwater vehicle REMUS 6000 was responsible for finding the elusive wreck. REMUS has been with the project since the beginning: The machine created the first side-scan sonar images of the site. After that, REMUS journeyed to a point 30 feet above the site and captured high-resolution photos of the ship's distinctive bronze cannons, which are engraved with dolphins. REMUS's documentation of this defining feature allowed scientists to positively identify the wreck as the fabled San José. (Thanks to whoever had the idea to put dolphins on the cannon in the first place.)

WHOI also released REMUS's photos of the wreckage, which show details of the horde, including ceramics and those famous cannons. "This constitutes one of the greatest—if not the biggest, as some say—discoveries of submerged patrimony in the history of mankind,” Colombian president Juan Manuel Santos said back when the treasure was discovered.

The San José's treasure is the subject of a legal battle for ownership between Colombia and U.S. salvage company Sea Search Armada, which helped look for the wreck. In 2011, four years before the San José was even found, the court ruled that the booty belongs to Colombia, but the dispute is ongoing. Because of the legal drama, the exact location of the wreck remains a government secret.

Below, check out the newly released pictures for a closer look at cannons, teacups, and other ceramics.

Researchers Accidentally Discover 128-Year-Old Shipwreck

Scientists conducting a routine survey of the waters along Australia's east coast got more than they bargained for when they accidentally discovered a 128-year-old shipwreck.

Their encounter with the sunken Carlisle, which sank in 1890, was captured on camera, and Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) has released footage showing an aerial view of the wreckage, teeming with schools of fish.

The researchers were mapping the seafloor of Bass Strait, which separates mainland Australia from the island of Tasmania, to improve nautical charts for the major shipping route, according to Mashable. During a scan of the waters, the sunken ship showed up as a "blip," ABC reports.

"We just happened to go over this blip, and we noticed it, and thought, 'Oh jeez, that looks just a little too much like a shipwreck,' and so we did a little bit more investigating and looked at it digitally," CSIRO hydrographer Matt Boyd told ABC. "Then once we established that yes, it was a shipwreck, we put a drop camera down."

Volunteers from the Maritime Archaeological Association of Victoria then went to the site and confirmed that the ship was indeed the Carlisle. It most likely collided with rocks while sailing from Melbourne to Newcastle, where it was supposed to pick up coal on its way to South America. All 23 crew members survived, escaping on three life boats.

The researchers discovered two more shipwrecks during a weeklong expedition from Brisbane to Hobart, one of which was identified as the HMAS Pioneer, a ship built for the British Royal Navy in 1900 that was scuttled in 1931.
