To celebrate International Women’s Day (Thursday, March 8), National Geographic is welcoming its first guest editor for the @NatGeo Instagram account: actor, activist and UN Women Global Goodwill Ambassador Emma Watson. Working alongside National Geographic’s editorial team, Emma will curate the account and highlight the work of eight female Nat Geo photographers from Saudi Arabia, Iran, Azerbaijan, Australia, the U.S. and the Philippines throughout the day starting at 8 a.m. EST. Their photos cover a wide range of important topics relevant to women around the world today.
