Solar System Portrait



On another Valentine's Day 25 years ago, cruising four billion miles from the Sun, the Voyager 1 spacecraft looked back one last time to make this first ever Solar System family portrait. The complete portrait is a 60 frame mosaic made from a vantage point 32 degrees above the ecliptic plane. In it, Voyager's wide angle camera frames sweep through the inner Solar System at the left, linking up with gas giant Neptune, the Solar System's outermost planet, at the far right. Positions for Venus, Earth, Jupiter, Saturn, Uranus, and Neptune are indicated by letters, while the Sun is the bright spot near the center of the circle of frames. The inset frames for each of the planets are from Voyager's narrow field camera. Unseen in the portrait are Mercury, too close to the Sun to be detected, and Mars, unfortunately hidden by sunlight scattered in the camera's optical system. Closer to the Sun than Neptune at the time, small, faint Pluto's position was not covered.

February 14th 1779: Captain Cook dies


On this day in 1779, the British explorer James Cook died aged fifty in Kealakekua Bay, Hawaii. Cook is famous for his ‘discovery’ of Australia in 1770, where he landed at Botany Bay and claimed the island for Great Britain. This set the stage for further exploration of the nation and settlement by the British, initially using the island as a penal colony. This colonisation was accompanied with a campaign of violence and persecution against the indigenous Australians, and has left a legacy that is still felt today in modern Australia. After his seminal voyage to Australia, Cook continued his travels and undertook three voyages in total. On the third voyage, Cook landed in Hawaii where the indigenous islanders allegedly initially worshipped him as a god, as his arrival fit the story of the return of their deity Lono. In February 1779, a small group of Hawaiians stole one of Cook’s small boats, and Cook attempted to take their leader hostage in retaliation. The relations between Cook and his men with the indigenous Hawaiians were therefore no longer amicable. Tensions came to a head when the Hawaiians attacked Cook as he was on his way to kidnap the king, and in the fray the explorer was stabbed and subsequently died. Cook’s body was prepared and buried per Hawaiian tradition, a sign that the islanders continued to hold the captain in some measure of esteem. Several of Cook’s sailors also died in the altercation, while the remaining crew continued with the voyage, returning to Britain in October 1780.

February 13th 2008: Australian apology


On this day in 2008, the Australian Prime Minister Kevin Rudd made a formal apology to indigenous Australians, especially the Stolen Generations, for years of mistreatment and oppression. The apology was passed unanimously by both houses of the Australian Parliament and was one of the first acts of the new Parliament. The apology was for the policies of the Australian federal and state governments who had forcibly taken children of indigenous Australians and Torres Strait Islanders away from their families - the Stolen Generations - in what was essentially an attempted cultural genocide. Rudd pledged to bridge the gap between indigenous and non-indigenous Australians. Australia also commemorates an annual ‘Sorry Day’ on May 26th in an attempt to come to terms with the legacy of indigenous persecution.



"The time has now come for the nation to turn a new page, a new page in Australia’s history by righting the wrongs of the past and so moving forward with confidence to the future."
