The Amazon river is known to be the second longest in the world, shorter only than the Nile but, remarkably, scientists have discovered another river flowing thousands of feet beneath it.
Researchers from Brazil's National Observatory believe the subterranean river is 3,700 miles long, about the same length as the Amazon on the surface.

Dr Valiya Hamza, from the BNO, said the discovery of the underground river came from studying temperature variations at 241 inactive oil wells drilled in the 1970s and 1980s by Brazil's state-run oil company, Petrobras.
