A dark legacy of the Nazi Era looms far beyond Pluto in the cold outermost reaches of our solar system. Earlier this week we reported that NASA’s New Horizons mission team published the first results of its New Year’s 2019 flyby of the farthest world ever explored, a planetary building block and Kuiper Belt object called Ultima Thule, also known less poetically as object 2014 MU69.

In 1938, decades before the 2019 New Year’s party celebrating the New Horizon’s Mission discovery, the Nazis, so the apocryphal story goes, sent a large team of explorers – including scientists, military units and building crews on war ships and submarines – to the Queen Maud Land region of Antarctica.

While mapping the Queen Maud Land, reports Mental Floss, they discovered a vast network of underground warm-water rivers and caves. One of these caves extended down as far as 20-30 miles and contained a large geothermal lake. The cave was explored and construction teams were sent in to build a city-sized base, dubbed Base 211 or New Berlin, that hosted the SS, the Thule Society, “serpent cults,” various Nazi occultists, the Illuminati, and other shadowy groups.

Ultima Thule or Thule “is a concept that’s very malleable, it’s been around along time,” Eric Kurlander, a historian at Stetson University who has studied Nazi supernatural beliefs, told Newsweek. “It’s not inherently political.” But he added that applying the term to the distant target of a spacecraft might have appealed to Nazis. “The Nazis were fascinated by space and rocketships and things like that,” Kurlander said.
