The largest living organism on Earth
Today marks the second-ever World Reef Day, an observance created to help focus global attention on the deteriorating health of our planet"s vital reef systems, and also to help marshal efforts to help them recover. Why should we care about the health of ecosystems such as the Great Barrier Reef, seen in this photo? Because reefs are an easy indicator of how healthy our oceans are. And right now, reefs aren"t doing too well. What can we do? Learn about reefs—not just the dangers that put healthy reefs at risk, but why reefs are such a critical part of Earth"s greater ecosystems.Desktop Version
Come out of your shell for World Turtle Day
Come out of your shell for World Turtle Day
Make way for the green sea turtle, which you’ll find—if you’re lucky—swimming in tropical and subtropical coastal waters around the world. You’ll notice that despite its name, the green sea turtle’s shell is not green at all. The name comes from the color of its fat, which takes on a greenish hue after the adult turtle starts eating seagrass and algae. Unfortunately, like many other sea turtle species, the green sea turtle is endangered and its population shrinking due to hunting, boat-propeller accidents, plastic pollution, and loss of nesting grounds.Desktop Version
Installation art turns heads
Installation art turns heads
If you ever encounter a giant plastic snail in the city or an army of rainbow-colored meerkats holding sentry outside a historic building, it’s likely an art installation from the Cracking Art collective. The group uses recyclable plastic to craft vivid representations of meerkats, elephants, snails, and other natural creatures for traveling art installations in unexpected locations. The collective’s use of plastic is meant to call attention to the sometimes blurry connection between natural and artificial reality, inviting viewers to reexamine the world around them. The meerkat exhibit on our homepage took place in 2015 at Le Mans Cathedral in Le Mans, France.Desktop Version

Today we"re showing off a serene scene at a Christmas tree farm outside Peterborough, Ontario, Canada. If you were to visit a farm like this today, however, it"s unlikely you"d find much peace and quiet. Of the 25 million to 30 million natural Christmas trees sold each year in the US alone, 98 percent of them come from farms. "Tis the season for tree chopping. Oregon, home to the popular noble and Douglas firs, produces the most Christmas trees of all US states, shipping much of the harvest to California. North Carolina, of Fraser fir fame, comes in at No. 2. Canada is the world"s largest exporter of Christmas trees, spreading holiday cheer around the world.Desktop Version
National Park Week: Wind Cave National Park
National Park Week: Wind Cave National Park
Hidden below the prairie at Wind Cave National Park, you’ll find something unexpected: one of the longest caves on the planet. This site includes 140 miles of explored passageways. What’s above ground is equally special, as the prairie supports one of the most genetically pure herds of bison in the country.Desktop Version
It s Census Day—make it count
It s Census Day—make it count
It"s Census Day, and we"re marking the once-in-a-decade head count with this populous pic of nesting king penguins in Antarctica. You"re probably wondering: Shouldn"t this crowd of penguins be social distancing right now? A smart observation, but the new coronavirus actually hasn"t been observed in Antarctica at all (it"s the only continent with no cases), nor have birds been shown to spread it. So, we"re giving these avian gatherers a pass, but we encourage you to stay safe at home. With care and patience, we"ll get back to enjoying each other"s company just like these feathered friends.Desktop Version
A Welsh wonder turns 70
A Welsh wonder turns 70
Here on the west coast of Great Britain, we"re enjoying views of the windswept uplands and jagged peaks that surround the small village of Capel Curig in the heart of Snowdonia National Park. Renowned for its rugged and mountainous landscape, Snowdonia is the largest national park in Wales and home to over 26,000 people and even more sheep—the wooly farm animals outnumber people 3 to 1 in Wales. About 60% of the park"s population speak Welsh, one of Europe"s oldest languages, and today they will be wishing this spectacular setting a "pen-blwydd hapus" (happy birthday) as Snowdonia celebrates its 70th anniversary.Desktop Version
Incense making, Vietnam
Incense making, Vietnam
Tomorrow marks the start of the Lunar New Year, known as Tết here in Vietnam. With celebrations fast approaching, these craftspeople in the "incense village" of Quang Phu Cau have been busy. Incense is used both in places of worship and on altars in family homes during Tết. The bright orange, pink, and crimson incense sticks are made from bamboo shavings hand-dipped in spiced and dyed paste. They"re then dried before bundling for sale all over the country.Desktop Version
Storm rolls over the grasslands
Storm rolls over the grasslands
Today"s image of a thunderstorm moving over grasslands in Theodore Roosevelt National Park shows the power of nature and the power of conservation. In 1883, Teddy Roosevelt, then a New York State assemblyman, traveled to the North Dakota Badlands to hunt bison. During this trip, Roosevelt fell in love with the cowboy lifestyle and the freedom he experienced. Before heading back east, he became part owner of the Maltese Cross Ranch. A year later he was back in North Dakota and had built Elkhorn Ranch. Life in the West inspired Roosevelt, who began writing books and articles about it. He would go on to establish six national parks and 18 national monuments, greatly increasing the size of the National Park System.Desktop Version

Where can you find a red fox?
Where can you find a red fox?
The biggest of all fox species, the red fox lives in many different habitats around the world, including forests, grasslands, deserts, and mountains. This fox is in the Netherlands, but red foxes can be found throughout most of Europe, as well as in temperate Asia, North Africa, and North America. A male fox is called a dog, and the female a vixen. A young fox is a kit, cub, or pup. Foxes live in groups called skulks. The red fox"s tail accounts for about a third of its length, and it can serve as a blanket, as well as a flag the fox raises to communicate with other foxes.Desktop Version

Wander the ancient medina
Wander the ancient medina
This colorful alleyway is in the medina—the ancient part—of the Moroccan city of Tétouan. From above, the medina appears to be a maze of traditional white plaster buildings surrounded by rampart walls and seven magnificent gates. But inside the maze, some alleyways like this one display a burst of color, an embellishment created by mixing pigments into the buildings" plaster. The passageways here are tall and skinny, large enough for a donkey and its handler to pass by, but too small for vehicles, so they invite peaceful strolls through the colorful shade.Desktop Version

For some Monday inspiration, we’re looking to the sky. In honor of NASA’s 60th anniversary, these are the contrails from a 2007 liftoff of the Space Shuttle Atlantis, which transported astronauts to space and back for 30 years before being retired here, at Kennedy Space Center, where visitors can view it in person.Desktop Version
It’s World Migratory Bird Day
It’s World Migratory Bird Day
Every traveler needs a place to rest from time to time. In the case of the snow goose, that place needs to be very large. Snow geese travel in flocks of hundreds, sometimes thousands, as they travel north to their springtime breeding grounds in the Arctic tundra. They stop along the way to rest and forage, relying on places like Montezuma National Wildlife Refuge in New York, where our homepage image was photographed. World Migratory Bird Day, recognized on May 12, highlights the need to protect habitat for winged travelers like these.Desktop Version

As autumn takes hold in China, a blanket of fan-shaped golden leaves—like this one at Xuanwu Lake Park in Nanjing—becomes a familiar sight. And it"s been that way for longer than anyone can remember, thanks to a native tree with a lineage going back eons, the ginkgo.Desktop Version
A lunar lantern celebration
A lunar lantern celebration
The Mid-Autumn Festival, or Moon Festival, is a celebration of the autumn harvest observed by the Chinese and other Asian peoples. It falls on the 15th day of the eighth lunar month, the full moon closest to the fall equinox. Originally a plea to the gods for rains to ensure a good harvest next year, Mid-Autumn Festival has become a more secular bit of autumn fun, with children and adults gathering to give thanks, eat sweet mooncakes, and light lanterns like the hand-painted ones we"re looking at here from a previous celebration in Singapore. This year, the Mid-Autumn Festival coincidentally lands on another holiday, China"s National Day.Desktop Version
Merry Christmas
Merry Christmas
For Christmas Day, we"re taking in the winter views on Mount Khomyak in Ukraine"s Carpathian Mountains. The bright green moss and the red of the fallen leaves pop against the snowy white, as though the forest were transforming into a magical band of Christmas elves. While much of the Christian world celebrates Christmas on December 25, for those who follow Eastern Orthodox Christian traditions—including many Ukrainians—Christmas is still a couple weeks away. Eastern Orthodox Christmas celebrations are tied to the Julian calendar, which is 13 days behind the more universal Gregorian calendar, so Christmas Day in Ukraine will be celebrated on January 7.Desktop Version

How will you celebrate International Literacy Day today? We’re highlighting this important observance with a photo of the Long Room of the Trinity College Library in Dublin, Ireland. Originally the Long Room was just one story tall, but in 1860, a second level was added to accommodate the growing collection. Literacy is considered one of the key pillars of success in the modern world. Programs to help those who want to learn how to read, or become better readers, are available in many cities—if there’s one near you, have you thought about volunteering there?Desktop Version
The Millennium at 20
The Millennium at 20
The view you"re seeing was first made possible exactly 20 years ago, but a photo from the same spot on June 10, 2000, might"ve come out a tad blurry. That"s because when the London Millennium Bridge opened to flocks of pedestrians on that date, it wobbled so much it was closed after just two days. But the bridge reopened with improvements in 2002, and today it"s stable in terms of not only lateral g-force but also photo-op popularity.Desktop Version
Brain coral
Brain coral
By using a long exposure and rotating the camera, a photographer highlights the spherical shape and grooved surface of a brain coral. You needn"t be a genius to guess how brain coral got its name. But you could just as easily call it "maze coral" after its labyrinthine surface. Either way, this sea organism is an apt mascot for today"s cerebral celebration: Puzzle Day!Desktop Version

Who s there? The largest owl in the world
To get us in the Halloween mood, we"re offering a seldom-seen sight—the Blakiston"s fish owl. Considered the largest of all living owls—about the size of a fire hydrant with a 6-foot wingspan—it"s among the rarest of owls, too. Experts estimate only a few thousand of these elusive birds remain, scattered in pockets of dense old-growth forests in northern Japan, the Russian Far East, northeastern China, and potentially North Korea.Desktop Version
Go with the rainbow flow
Go with the rainbow flow
Today"s photo brings us to the banks of Caño Cristales, the "liquid rainbow" that cuts a prismatic path through the heart of Colombia. From June through November, when the clear water is low, the abundant underwater plants that cover the riverbed show off their red, yellow, green, and blue hues. The star of the show—especially in this photo—is Macarenia clavigera, a riverweed that ranges from bright red to deep crimson or purple depending on its intake of sun rays. In August and September, when the florid flora is at its peak, the river"s a coveted nature excursion: Because the ecosystem is so fragile, visits are limited to guided tours.Desktop Version
A monastery in the mountain
A monastery in the mountain
Built into the side of a mountain in the Azat Valley of Armenia, the monastery of Geghard is one of the most-visited tourist destinations in the country. The location of the monastery has been inhabited for millennia and venerated by locals since the pre-Christian era due to the spring which emanates from one of the caves in the mountainside. The monastery was originally founded in the 4th century by Saint Gregory the Illuminator—the patron saint of the Armenian Apostolic Church—though none of the original buildings survive.Desktop Version
