The Great Pyramid of Giza is the last of the Seven Wonders of the Ancient World still standing. And now scientists have discovered a large and mysterious void at its heart. They've found an internal structure at least 30 metres long, directly above a passage known as the Great Gallery. It's got experts puzzling over what it is. The pyramid was constructed as a monumental tomb during the reign of Pharaoh Khufu more than 4,500 years ago. To peer into previously unexplored parts, researchers used an imaging technique called muon tomography. That involves tracking cosmic particles that bombard our planet at close to the speed of light and penetrate deep into solid objects. It's the first major inner structure found in the Great Pyramid since the 19th Century. Now scientists hope the noninvasive scanning technique will reveal more secrets of the ancient world.
