Emmy award-winner Phil Keoghan will host the network’s long-running series Explorer when it returns in fall, 2018. The series will have 20 new episodes.

The new season follows Keoghan as he treks into far regions to meet with National Geographic Explorers on the front lines of groundbreaking scientific, technological and historical discoveries.

“Phil embodies what it means to be a National Geographic Explorer — he’s undoubtedly interested and curious about investigating the relationship between the Earth and human life,” said Tim Pastore, president of original programming and production. Explorer is a show about informing and entertaining, and we’re confident that with Phil as host, he will be the catalyst for viewers to understand the way we fit into the world.”
