Jupiter Mosman, was born in north-western Queensland. When he was a small boy, he turned up at Kynuna Station south of Julia Creek in western Queensland. Hugh Mosman, owner of Tarbrax Station, was visiting Kynuna Station at the time and adopted the boy and named him John Joseph Jupiter Mosman. He called him Jupiter because his eyes were "large, luminous, and as limpid as a planet".

Hugh Mosman sold his property, Tarbrax, and decided to go prospecting. He travelled with Jupiter, to Ravenswood where  he became acquainted with the prospector George Clarke and together with a Mr Fraser commenced a prospecting  expedition in 1871.

The expedition set out from Ravenswood heading for the Seventy Mile Pinnacle, (now known as Mount Leyshon) after which they swung back towards the high bluff, (now known as Towers Hill), as it was an easily seen landmark.

In December 1871, the party arrived on the western side of the bluff and camped beside a creek where Jupiter discovered the gold-bearing brownstone quartz that led to mining of the deep-vein reef that they called the North Australian. Their claim was registered in Ravenswood. It was the first mine on the new Charters Towers goldfield. Many mines were later established that  provided a much-needed boost in the development of north Queensland.

Jupiter parted ways with Mosman in 1891 and went back to the land either gold-prospecting or working cattle.

He retired and lived at Eventide Home for the Aged in Charters Towers where he died on 5 December 1945 aged 85.
