The winners in Smithsonian Magazine's 13th annual photo contest has been announced.

We are excited to announce the winners and finalists of the 13th Annual Smithsonian.com Photo Contest. This year, we received over 46,000 submissions from photographers in 168 countries and territories. The images below stood out to the Smithsonian.com and Smithsonian magazine photo teams as the most striking and memorable entries. From Albert Ivan Damanik’s Grand-Prize-winning shot of ash flowing from the slopes of Mount Sinabung to Radim Schreiber's photograph of fireflies in a twilight forest, these photographs capture a moment in time for Smithsonian.com readers around the globe. Alice van Kempen's image of her bull terrier, Claire, in an abandoned train received the highest percentage of nearly 40,000 reader votes, earning her the Readers' Choice award. Congratulations to all!
