"Join explorers and scientists, master photographers and adventurers at National Geographic Live — a lecture series featuring behind-the-scenes tales and magnificent images from one of the world's largest non-profit science and education foundations."

So far I have seen this two lectures:

Kakani Katija: Ocean Currents "Can tiny sea creatures affect weather around the world? Emerging Explorer Kakani Katija looks to a new field of science for answers." Read on

Kevin Hand: Exploring Alien Oceans "The best chance of discovering life beyond Earth might lie in the icy moons of Jupiter." Read on
