   A closeup of the aurora australis over the Antarctic in the Blue Marble image highlights the thin fragile atmosphere that sustains all life on Earth. Note that South is up.

   These images, the first such images taken by humans in over 54 years, remind us of the beauty and the fragility our planet, and of our shared responsibility to care of it and of each other.
