Blood Falls seeps from the end of the Taylor Glacier. Scientists believe a buried saltwater reservoir is partly responsible for the red color, which is a form of reduced iron. Photograph by: Peter Rejcek, National Science Foundation, Date Taken: December 14, 2010

The Ferrar Glacier forms a wide highway from the polar plateau to McMurdo Sound. It was named for Hartley T. Ferrar, geologist of the British National Antarctic Expedition, 1901-04. Photograph by: Kelly Speelman, National Science Foundation, Date Taken: January 6, 2011

This Norwegian Lutheran Church is located at the abandoned Grytviken whaling station on South Georgia Island. The island is governed by Great Britain via King Edward Point Station, located a short distance from this church.

Nacreous Clouds
Nacreous clouds, observed on January 6, 2011. These polar stratospheric clouds at 80,000 feet are the highest of all clouds. They only occur in the polar regions when the stratospheric temperature dips below 100 degrees below zero Fahrenheit (-73 C). They are also the site of chemical reactions that break down ozone in the upper atmosphere and contribute to the creation of the ozone hole above Antarctica. Image credit: Kelly Speelman

South Pole Telescope
The 10-meter South Pole Telescope at Amundsen-Scott South Pole Station is shown here. The red lights are used to minimize light pollution, but still enable people to see while walking to and from the facility during the six months of darkness. This telescope collects data on cosmic microwave background radiation and black matter. Image credit: Daniel Luong-Van, National Science Foundation
