The National Geographic Society is marking its 125th anniversary with a live Google+ Hangout on Sunday, featuring primatologist Jane Goodall, filmmaker and explorer James Cameron, and the oceanographer who discovered the remains of the Titanic, Robert Ballard.
The trio, along with National Geographic explorers around the world, will take questions from the public in a live Google+ Hangout from 1-2.30pm ET (6-7.30pm GMT) this Sunday, 13 January, and will talk about the new age of exploration.
Everyone is invited to submit questions for the explorers via uploading a video question to YouTube with #NatGeo125, posting a question on Google+ or Twitter with #NatGeo125, commenting on the National Geographic News Watch blog, or leaving a comment on this Facebook post.
The Hangout will be viewable on the National Geographic Google+ page or on YouTube.com/NatGeo.
The event will be the first in a series of monthly National Geographic-Google+ Hangouts with explorers leading innovative field research around the world.
