“Moon Anomaly” -Massive Blob Detected Buried Under Solar System’s Largest Impact Crater

China’s Chang’e-4 mission


On Jan. 3, 2019, the Chinese spacecraft Chang’e 4 (above) safely landed on the Far Side floor of the Moon’s Von Kármán crater, naming the site, “Milky Way Base.” Located within an even larger four-billion-year-old impact crater known as the South Pole–Aitken basin roughly 2,500 kilometers in diameter and 13 kilometers deep –the largest impact crater in the Solar System –it now appears that the “Milky Way Base” sits atop of an abnormally massive blob buried deep below.


“Moon’s Two Faces” –Mystery Solved By Wayward Dwarf Planet Collision

Moon's Farside


The mystery of the stark difference between the Moon’s heavily-cratered farside and the lower-lying open basins of the Earth-facing nearside has puzzled scientists for decades began in the Apollo era with the first views of its farside. Measurements made by the Gravity Recovery and Interior Laboratory (GRAIL) mission in 2012 filled in more details about the structure of the Moon — including how its crust is thicker and includes an extra layer of material on its farside suggests the differences were caused by a wayward dwarf planet colliding with the Moon in the early history of the solar system.
