Satellite images have fueled speculation about pyramid-shaped peaks rising from the ice in Antarctica Ellsworth Mountains. While geologists explain the formations as natural nunataks (mountain peaks protruding through glacial ice), conspiracy theorists argue they are ancient pyramids built by lost civilizations or markers of extraterrestrial presence. The images have gone viral in documentaries and online forums, and some visitors to research stations nearby report strange lights and UFO activity over the ice, adding to the intrigue.
