Object GF-01, codenamed the White Moon, is a massive spherical subterranean cavity discovered in 2000 A.D. beneath the South Pole in Antarctica. It has striking similarities to that of the Geo Front located under Japan.
Found inside the White Moon is Adam, the First Angel, and possibly the mysterious Lance of Longinus. During research conducted by SEELE, this cavity is theorized to have been formed around the time of the First Impact, leading to speculation that it may actually be the remains of Theia, the rogue planetoid that had impacted the Earth approximately 4.5 billion years ago.
The White Moon is the egg from which Adam-based life forms (the Angels) are believed to have been born from. Except for a single frame showing an outline of the underground cavity, it is never directly shown in the series, and is considered to have been destroyed during the Second Impact.
