Icebergs, Antarctica

The name 'Antarctica' is derived from Ancient Greek word 'antarktikos,' meaning opposite the Arctic. The concept of an 'Antarctic region' was first mentioned by Greek philosopher Aristotle around 350 BCE. Despite this early reference, it wasn't until the 19th century that humans actually laid eyes on Antarctica. It is the coldest, driest and windiest of the Earth's continents, with temperatures plunging as low as -80 degrees Celsius. Vast ice sheets and glaciers found here hold about 70% of the world's fresh water. The waters are dotted with icebergs, as seen in today's image, which drift across the Southern Ocean and gradually melt over time. Species like Emperor and Adélie penguins, along with seals, mites, roundworms and moss piglets, have made this icy habitat their permanent home.
