Earth. Satellite image of the Earth, centred on Antarctica. The South Pole is at centre. Water is blue, vegetation is green, arid areas are brown, and snow and ice are white. Both land and ocean floor topography are shown. Antarctica is a frozen continent, permanently covered in snow and ice. Surrounding Antarctica are the waters of the Southern Ocean, mixing with the Atlantic Ocean (upper centre), the Pacific Ocean (lower left) and the Indian Ocean (centre right). Around the edge of the hemisphere is New Zealand (lower centre), Australia (lower right), and the southern parts of Africa (upper right, the island of Madagascar is also seen) and South America (upper left).

Comet Lovejoy at dawn
Comet Lovejoy at dawn over the Southern Ocean. At upper right is part of the Milky Way, the band of billions of stars that is our galaxy seen from the inside. Comets are icy bodies from the outer solar system that boil and form a bright tail of gas and dust as they approach the Sun. Comet Lovejoy reached its closest approach to the Sun on 16 December 2011. Photographed on 23 December 2011 from Cape Schanck, on the Mornington Peninsula, Victoria, Australia.

Iceberg. Mawson - Life and Death in Antarctica, 2008
A colour image of a large iceberg in the Southern (or Antarctic) ocean. In a bold historical experiment, adventurer Tim Jarvis retraces the gruelling experience, with similar meagre rations, primitive clothing and equipment to uncover what happened to Mawson physically—and mentally—as a man hanging on the precipice of life and death.
