Pyramids in Egypt increased by 17. Infrared satellite images found buried pyramids, 1000 new tombs and 3000 ancient settlements.
NASA satellites from 700 km above the earth, equipped with powerful cameras filmed the pyramids. In principle they can photograph objects with a diameter less than 1 meter of ground.
Infrared cameras are used to capture various materials beneath the surface.
The team, led by Dr. Sarah Parkak, analyze satellite images. Ancient Egyptians built their houses of adobe, which is much denser than the surrounding soil. So in the pictures are seen buried houses, temples and tombs.
"These are the only objects near the surface. There are thousands of sites buried by sediments from the Nile. This is only the beginning of this type of research, "said Dr. Parkak.
Two potential pyramids are in the Sahara region. On them already have begun trial excavations, which show that they can become one of the most important archaeological sites in Egypt.
The ancient Egyptian pyramids are massive monuments with a large square base and four triangular walls that meet at a common point at the top. The ancient Egyptians probably chose that form of the tombs of their pyramids because of their solar religion.
They believed that the Egyptian sun god Rah, who is the father of all pharaohs, had appeared on Earth from a pyramid-shaped mound, and then created all the other gods.
Donald Redford is one of the researchers of the Egyptian pyramids. He believes that the Egyptians began to raise immediately pyramids around 2700 BC and it lasted a thousand years until 1700 BC.
The first pyramid was built by King Djoser of the third Egyptian dynasty. Its architect was Imohtep. Today the most famous pyramids in Egypt are the Pyramids at Giza, the most popular is the Great Pyramid, designed for Pharaoh Khufu.
According to Professor Robert Redford who made his calculations, for the construction of the Great Pyramid were needed from 20 000 to 30 000 workers and about 23 years. For comparison: for the construction of Notre Dame were needed 200 years.
