According to an article, published in the Nature-journal this tuesday, an international group of scientists has used modern technology to visualize the inside of the pyramid. For the first Time since the 19th century, scientists discovered a large, previously unidentified chamber inside the Great Pyramid in Giza by using muon-detectors. This newly discovered large space is around 30 meters in length and could be horizontal or sloped like the Grand Gallery. The Egyptian Ministry of Antiquities has prohibited any intrusive techniques, such as drilling holes through the stone and inserting a camera, to prevent damage to the pyramid. The Nature-Journal has published some very interesting pictures and graphics about the newly discovered chamber which you can find and see here on nature.com. A short 360-degrees video about the discovery can be watched here on cnn.com.
