The last mineral thought to have been unique to the Moon has been discovered in the remote Pilbara region of Western Australia. Tranquillityite, named after the Sea of Tranquillity where the Apollo 11 moon-walkers landed in July 1969, was tentatively identified while studying a polished slice of Earthly rock in a scanning electron microscope.
