Google has just announced that they have begun making the entire 10-million photo archive of LIFE magazine available on their servers. To access the images just do an image search for a topic, adding "source:life" to your search query. Searching for "antarctica source:life" or "arctic source:life" serves up some stunning photography, most of it never published before. Here is just a small sampler:

Lt.j.g. John Tuck in charge of Anundsen-Scott base in Antarctica. (1956)

Beautiful vistas of rocky escarpments, snow-topped peaks, as seen from low-flying plane. (1956)

Russians at Mirny station entertaining visiting US scientists working on joint project in penguinology. (1964)

Google says that so far it has only added about 20% of LIFE's photo archives to its servers, but that the rest will be available in the coming months, so check back often.
