Antarctica might be an icy, barren, windswept landscape today, but millions of years ago it was home to thriving forests, dinosaurs, and a breathtaking landscape replete with rivers, lakes and massive canyons. Much of its past is still sitting there, buried underneath layers of ice, waiting to be discovered in the form of fossils and geology. It's even possible that ancient creatures still live under Antarctica's ice, hidden for millennia beneath the continent's cold glacial cap.

here are a lot of lakes in the world. Big lakes, little lakes, red lakes, blue lakes. According to a new survey, there are roughly 117 million lakes on the planet. Using satellite images the survey team counted all the lakes in the world that were bigger than half an acre, says Uppsala University in a release. It's the first time we've ever had such a thorough census of the world's lakes, they say.
