Lake Van is one of the largest alkaline lakes on Earth, but today it has another superlative: Tournament Earth 2021 champion.
This year, readers, astronauts, and NASA staff chose 32 photos — shot by the astronauts from the International Space Station — to compete in our tournament. Lake Van was slotted as a #8 seed, but knocked out higher seeded fishing boat lights (#1 seed), Elba at night (#4), Typhoon Maysak (#2), the castellanus cloud tower (#6), and finally Stars in Motion (#3) to win the crown. Across the five rounds, more than 930,000 ballots were cast, a record in the history of our Tournament Earth competitions.
The winning image, showing a northeastern portion of the lake, was shot by astronaut Kate Rubins while orbiting on the space station in September 2016. Lake Van is an endorheic lake—it has no outlet, so its water disappears by evaporation—with a pH of 10 and high salinity levels. Turbidity plumes, which appear as swirls of light- and dark-toned water, are mostly comprised of calcium carbonate, detritus, and some organic matter. The lake is also the largest water body in Turkey.
Lake Van also has quirkier characteristics. According to legend, it is the home for a lake monster popularized in Turkish folklore. Akin to the Loch Ness monster, the Lake Van monster is rumored to look like an ancient marine reptile such as a plesiosaur. No monster-like creature has been confirmed, although archeologists have found parts of a 3,000-year-old castle buried under the lake’s waters.
The Lake Van region is also home to a special cat breed known as the Van cat. The felines have been seen swimming in Lake Van and are known for their almond-shaped eyes, often of different colors.

Thank you for voting in this year’s #TournamentEarth. We hope to bring you more competitions like this in future months and years.
It is that time of year again…Tournament Earth is back! This time, the theme is astronaut photography. For more than 20 years, astronauts have been shooting stunning photos of Earth from the International Space Station that highlight the planet’s beauty, complexity, and vulnerabilities.
So which are the most unforgettable photographs of Earth taken from the space station? Over the next five weeks (March 8-April 13), you can help decide.
While you wait for the Round 1 results, download the bracket here and challenge your friends. After you fill out that bracket, post your predictions in the comment thread for which four photos will make the semifinals and which one will be crowned champion. We can’t offer prize money or a trip to the Moon, but bragging rights are forever if you can guess the eventual champion.
Also, bookmark this space. We will provide updates later in the tournament and highlight some of your predictions, commentary, and insights lower in the post. Just remember to use the hashtag #TournamentEarth and tag @NASAEarth on social media (we’re on Twitter, Facebook and Instagram) or we might not see your post.
For more than 20 years, astronauts have been shooting photographs of Earth from the International Space Station. Before that, they looked down from Mercury, Gemini, Apollo, Skylab, the Space Shuttles, and MIR. They have brought us unique views of our home planet in all of its wonder, beauty, and ferocity. They have also made some interesting and timely science observations along the way.
More than 1,000 of those photos have been published here on NASA Earth Observatory. We would like you to help us choose the best in our archives. In early March, we will launch Tournament Earth: Astronaut Photography, and we want you to be part of the selection committee.
From now through February 19, 2021, search our archives and point out the best photos shot by the astronauts. Post the URLs of your favorite photos in the comments section below.
Please note that there are 30+ pages of images to scroll through — an internet rabbit hole of incredible beauty.
In March 2021, we will include some of your selections in Tournament Earth, a head-to-head contest to vote for the best of the best from our archives. Each week, readers will pick from pairs of images as we narrow down the field from 32 nominees to one champion. The Tournament Earth champion will be announced in early April.
So get browsing and get choosing. Then post your favorite URLs in the comments section by February 19.

Every time we run one of these tournaments, we are surprised by what catches the eyes of our readers. It is time to surprise us again. Cast your votes now in round three to pick the best four of the Earthly 8. Voting ends on April 13 at 9 a.m. U.S. Eastern Time. Check out the remaining competitors below.
“Past Winners” Bracket: Ocean Sand, Bahamas (#5) vs. A View of Earth from Saturn (#2)
Fire in the Sky and On the Ground has pulled off two massive upsets. In round 1, it beat #2 seed Night Light Maps Open Up New Applications, 71 to 29 percent. In round 2, Fire beat the sentimental favorite and oldest image in Tournament Earth, All of You on the Good Earth — the original Blue Marble photo (1968) and the inspiration for the first Earth Day (1970). The voters chose the auroral fire over Apollo 8 fame by 57 to 43 percent.
“Ice and Land” Bracket: Where the Dunes End (#8) vs. Retreat of the Columbia Glacier (#6)
Since its launch on the web in April 1999, NASA Earth Observatory has published more than 15,500 image-driven stories about our planet. In celebration of our 20th anniversary — as well as the 50th anniversary of Earth Day — we want you to help us choose our all-time best image.
For now, we need you to help us brainstorm: what images or stories would you nominate as the best in the Earth Observatory collection? Do you go for the most beautiful and iconic view of our home? the most newsworthy? the most scientifically important? the most inspiring?
Search our site and then post the URLs of your favorite Earth images in the comments section below. Please send your ideas by March 17.
In late March 2020, we will include some of your selections in Tournament Earth, a head-to-head contest to vote for the best of the best from our archives. Each week, readers will pick from pairs of images as we narrow down the field from 32 nominees to one champion.
The all-time best Earth Observatory image will be announced on April 29, 2020, the end of our anniversary year.

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!
