The Blue Marble is a famous photograph of the Earth, taken on December 7, 1972, by the crew of the Apollo 17 spacecraft, at a distance of about 45,000 kilometres. The photograph was originally oriented with the south pole at the top, with the island of Madagascar visible just left of center, and the continent of Africa at its right.

The Magnificent Tail of Comet McNaught  - Comet McNaught, the Great Comet of 2007, grew a spectacularly long and filamentary tail. The magnificent tail spread across the sky and was visible for several days to Southern Hemisphere observers just after sunset.
