A team of scientists has uncovered what may be one of the largest hidden geological structures on Earth — a continent-sized “megastructure” buried deep beneath Antarctica. It’s so massive, in fact, that it’s larger than the country of India. Fun geology fact: India is the world's seventh largest country (behind Australia) in terms of landmass. The discovery, published in Nature Geoscience , was made using seismic imaging and advanced geophysical data that allowed researchers to peer beneath the Antarctic ice sheet and crust. The study reveals a vast region of unusually thick and ancient rock extending across much of East Antarctica. Researchers estimate the buried structure spans millions of square kilometers, making it comparable in size to major landmasses such as India or Western Europe. If exposed at the surface, it would rank among the largest geological features on the planet.…
