The 2015 National Geographic Photo Contest has come to a close and the publication has officially announced the grand prize winner (out of more than 13,000 submissions) as well as the winners in three categories: Nature, Places, and People.

The grand prize and Nature winner is Melbourne, Australia-based photographer James Smart. His photo, titled Dirt (above), shows a tornado touching down near a home in Simla, Colorado. "The tornado was slowly getting bigger as it picked up the dust and soil from the ground on the farmland, Smart told NatGeo. "It wasn’t moving very fast, so we kept getting closer as it tracked next to the home as you can see in the image." Smart won $10,000 and a trip to National Geographic's headquarters in Washington, D.C. for the National Geographic Photography Seminar this month.

In the Places category, the first-place photograph, titled Asteroid, was taken by Francisco Mingorance of Andalusia, Spain, and shows a marsh destroyed by "radioactive discharges." The winner of the People category, Joel Nsadha, photographed a Ugandan man who takes his custom bicycle to watch people play soccer in the slums every day. Check out the winning photos below, as well as others that have been recognized as Honorable Mentions, and head to the 2015 National Geographic Photo Contest page to view the full gallery of submissions.

"On the occasion of the preparation of a report on Ríotinto from the air, I decided to include phosphogypsum ponds located in the marshes of red and whose radioactive discharges has destroyed part of the marsh. As an environmental photojournalist had to tell this story and report it but had to do with an image that by itself attract attention of the viewer. I discovered this on a low-flying training that caught my attention for its resemblance to the impact of an asteroid on its green waters." Location: Cardeñas, Andalusia, Spain.
