Resting at a depth equivalent to about 17 Empire State Buildings stacked top to bottom, the Factorian Deep was discovered in 2019 by American explorer and entrepreneur Victor Vescovo, as part of his Five Deeps Expedition to map the deepest points of the world's five oceans. Vescovo personally piloted a submersible named "Limiting Factor" (for which the Factorian Deep was named) to the bottom of the Atlantic Ocean's South Sandwich Trench – an undersea canyon that spans roughly 600 miles (965 kilometers) of seafloor between South America and Antarctica.

So, where is this charismatic leader buried? Does he have a monumental tomb like the pyramids built for the ancient Egyptian pharaohs, or a mausoleum with terra–cotta warriors, like the one built for China's first Qin emperor?

The finding comes from a study of prehistoric sea-deposits found on the shores surrounding the "doomsday" Thwaites Glacier and the neighboring Pine Island Glacier, both located on the West Antarctic Ice Sheet. The chilling news? Antarctica's glacial melt, driven by climate change, is advancing faster than ever before in recorded history, researchers have reported June 9 in the journal Nature Geoscience.
