A mineral brought back to Earth by the first men on the Moon and long thought to be unique to the lunar surface has been found in Australian rocks more than 1 billion years old.
Named after Apollo 11's 1969 landing site at the Sea of Tranquility, tranquillityite was one of three minerals first discovered in rocks from the Moon and the only one not to be found, in subsequent years, on Earth.
Australian scientist Birger Rasmussen said tranquillityite had "long been considered as the Moon's own mineral" until geologists discovered it, by chance, in rock from resources-rich Western Australia.
THE green flares of the aurora australis seen on Saturday night were the brightest they have been in seven years, says Astronomical Society of Tasmania spokesman Bob Coghlan.
Mr Coghlan said the natural light show was caused by photon oxygen emissions in the Earth's upper atmosphere reacting against strong solar winds, causing an eerie green glow.
