Professor Lee Berger, palaeontologist, explorer and member of The National Geographic Society, gestures as he explains the scientific relevance of discovering Homo Naledi in the Rising Star caves system in The Cradle of Human Kind, on May 11, 2023. The news shakes the foundations of human evolution: world-renowned paleontologist Lee Berger announced on Monday that he had discovered the oldest graves ever found in South Africa, pushing back the first traces of mortuary practices by some 100,000 years . The oldest tombs discovered so far were found in Israel and Egypt at the beginning of the 20th century. They date from around 100,000 years before our era and house the remains of Homo sapiens, the direct ancestor of man. The burials unearthed in South Africa date from -200,000 to -300,000 years.

The latest view of Saturn from NASA's Hubble Space Telescope captures exquisite details of the ring system?which looks like a phonograph record with grooves that represent detailed structure within the rings?and atmospheric details that once could only be captured by spacecraft visiting the distant world. One such intriguing feature is the long-lasting hexagon-shaped structure circling the planet's north pole. It is a mysterious six-sided pattern caused by a high-speed jet stream. NASA's Voyager 1 spacecraft first discovered the
