The images were acquired by the Earth Polychromatic Imaging Camera (EPIC) on the DSCOVR satellite, which orbits about 1.6 million kilometers (1 million miles) from Earth. EPIC maintains a constant view of the fully illuminated Earth as it rotates. About twice a year the camera captures images of the Moon and Earth together as the orbit of DSCOVR crosses the orbital plane of the Moon.
While we aren’t aware of any homecoming parades to honor the 2016 champion, watching the video above (or listening to all of Pink Floyd’s Dark Side of the Moon) seems like a fitting way to celebrate. The images in the movie below were taken over the course of five hours on July 16, 2015. The North Pole is toward the upper left, reflecting the orbital tilt of Earth from the vantage point of the spacecraft. The far side of the Moon was first observed in 1959, when the Soviet Luna 3 spacecraft returned the first images. Since then, several missions by NASA and other space agencies have imaged the lunar far side.
For the second year in a row, an image from the Canary Islands took the championship of Tournament: Earth. In 2013, a submarine volcano near El Hierro Island was the crowd favorite. This year, it was a shot of the entire island chain that dominated the vote. When “Trailing the Canaries” faced “Activity at Kliuchevskoi” in the championship round, it wasn’t just a win for the Canaries image; it was a blowout. Of the nearly 50,000 votes cast, 96 percent went to the Canary Islands image.
To salute our many readers from the Canaries, we’ve combed through our archives and selected five of our all-time favorite images involving the island chain. They are posted below from oldest to newest. Click on each image for more details. Enjoy!

I hope your brackets are ready because polls for round one of Tournament Earth close today at 4 p.m EST/9 p.m. UTC. Second round voting will open on Monday at 9 a.m. EST/ 1 p.m. UTC). Also, stay tuned for occasional posts on Earth Matters with details about how images fared in the competition.
The images in the tournament are a blend of reader and staff favorites from the 2013 calendar year. The images are seeded and divided into four brackets categorized by image type: data visualization, photographs, art, and events. The top seed in the data visualization bracket — and the No. 1 seed overall — is a global map of fine particulate pollution that garnered more than 150,000 page views in 2013. The photo section is topped by a nighttime view of Liege, Belgium, as photographed by an astronaut on the International Space Station. The “art” section is led by a satellite image of a rare snowfall in Great Britain. The top seed among natural events is a January 2013 satellite image of a smog and pollution over China — the second most popular image on the Earth Observatory last year. Six of the seven most-viewed images on the site are battling in the events section. Good luck with your bracket!
