I've been a fan of the photography and the stories featured in National Geographic Magazine since I was a child. I explored the world by simply turning the pages. It featured some of the most amazing and groundbreaking photography then and it's never stopped finding new ways to surprise. On January 13, 2013, the National Geographic Society will celebrate its 125th anniversary and its evolution from a small scientific body to one of the world's largest educational and scientific organizations committed to inspiring people to care about the planet. The Society has shared some images that represent those moments of discovery and will continue in its 126th year, to provide a front-row seat to what's happening at the extremes of exploration - bringing everyone along for the ride through its storytelling and photography. You can even "hangout" with some of it's more prominent explorers Jane Goodall, James Cameron and Robert Ballard, on the anniversary date, 1 p.m. EST
