Contemporary artist Rachel Sussman has photographed the world's oldest continuously living organisms that are 2,000 years old and older. Braving some of the world's harshest climates spanning from Antarctica to Greenland, the Mojave Desert, and the Australian Outback, she's compiled her photographs and stories of her epic adventures into the beautiful new book The Oldest Living Things in the World. The book includes 124 photographs and 30 essays.
Here are some of the pictures.
Still curious? Sussman gave a 2010 TED talk on the project.
