LOOK: NASA wants you to vote for the best photo taken from space • PhilSTAR Life

The National Aeronautics and Space Administration (NASA) Earth Observatory is holding a “Tournament Earth” astronaut photography competition to choose the best image of planet Earth taken from space—and they want your vote.

Committed to sharing images, stories, and discoveries from the space bureau, Earth Observatory asked for photos from astronauts and ground members from the International Space Station (ISS), so the public can choose which image is most, err, out of this world.

Starting with 32 photos, the competition is now on its 3rd round with only eight finalists left. The choice comes down to four ISS regions: Unity, Cupola, Destiny, and Tranquility.

“We started this tournament with 32 photos and now we are down to 8," the Earth Observatory site reads.

"All of the #1 seeds are gone. Two #8 seeds are dominating their groups. Six remaining competitors rise high above the planet, while two are grounded in the blues and greens of the surface."

Voting started on March 23 and will end on March 29 at 12 noon, US Eastern Time. You can vote by simply clicking on the photos and reading their backstories at earthobservatory.nasa.gov/tournament-earth.
