NASA has opened voting for itsTournamentEarth 2014 photo competition
, which takes Earth images captured by satellite and makes them go head to head. Users (that's you!) vote on the best shots, which then go on to the final round. You can create your interactive brackethere
. Note: Voting ends Friday, March 14. Our favorite to take the whole thing: An eruption at Kliuchevskoi, a stratovolcano on the Kamchatka Peninsula of Russia (above) was photographed by the Expedition 38 crew aboard the International Space Station.PHOTOS: 2013 Top 20 Earth Images Contest

Tristan da Cunha, an island in the southern Atlantic Ocean, is more than 2,300 miles (3,700 kilometers) from the coastline of Antarctica. A volcano sits at the island's center. "The last known eruption of Tristan da Cunha took place in 1961–1962," writes William L. Stefanov for NASA, "and forced the evacuation of the only settlement on the island, Edinburgh of the Seven Seas, on the northern coastline (obscured by clouds in this image). The town is considered to be the most remote permanent settlement on Earth, with its nearest neighbor located 2,173 kilometers (1,347 miles) to the northeast on the island of St. Helena."PHOTOS: Changing Face of Earth in 2013

The Canary Islands appear to have tails made by smooth and choppy water, and the reflection of sunlight. The image was captured by the same satellite that photographed Great Britain under snow. All of these images are in the current Round of 16. Got a favorite?You can't win if you don't play
