Majestic-12, also known as MJ-12, is a part of the US government that oversees US relations with extraterrestrials. See Majestic-12 Discussion and Wikipedia.

MJ-12 was founded following the Roswell Incident in 1947 by President Truman by Presidential Directive. Initially tasked with covering up the Roswell Incident and researching into the alien spacecraft that was recovered, the depth of its mission changed in 1980 when MJ-12 made contact with Greys, actual Extraterrestrial Biological Entities. The Greys provided them with advanced technology and other information, which MJ-12 adapts for use. The organization has twelve divisions, each with their own responsibilities and sub-projects:

Majestic-12 runs very few facilities exclusively. More often there are Majestic-only buildings at military bases and federal reservations, or restricted offices at CIA, NSA and NRO facilities around the world.1
