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 little bit of Wonderland in New York City
A little bit of Wonderland in New York City
This statue of Alice in Wonderland is found on the east side of New York’s Central Park, near 75th Street. It was commissioned in 1959 by a philanthropist whose late wife had enjoyed reading ‘Alice’s Adventures in Wonderland’ to their children. "Alice" was first published on this day in 1865 by the English writer Charles Lutwidge Dodgson, who wrote under the pseudonym Lewis Carroll. His story of a little girl who falls through a rabbit hole into a fantasy world was inspired by a real girl, Alice Liddell, and it went on to become a classic, inspiring films, television shows, and artwork like this.Desktop Version
Who s there? The largest owl in the world
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
Aurora borealis
Aurora borealis
You don"t have to go all the way to Alaska to see the northern lights (they"ve been spotted as far south as Hawaii). But based on this stunner of a photo, we recommend it. And the farther north the better: Auroras are more frequent and intense the closer you are to the North Pole.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
It’s oh so quiet
It’s oh so quiet
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
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
Big-wave hunters watch Nazaré
Big-wave hunters watch Nazaré
Today"s image captures Brazilian surfer Rodrigo Koxa in action, surfing a record 80-foot wave off the coast of Nazaré, Portugal. Nazaré began attracting surfers in the 1960s and has since become a major destination for men and women who want to surf some of the world"s biggest waves. Nazaré"s Praia do Norte (North Beach) is the site of the two latest records for largest wave ever surfed. The previous record was set by American Garrett McNamara on November 1, 2011, when he rode a 78-foot wave here. Then, on November 8, 2017, Koxa set a new record with this ride.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
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
Hollywood s big night
Hollywood s big night
It"s Oscars night in Tinseltown, and we"re offering you a moment"s escape from the paparazzi to gaze over the glittering megalopolis of Los Angeles—and to get an unfamiliar view of a familiar landmark. The Hollywood Sign originally read "Hollywoodland" when it was erected in 1923 and festooned with light bulbs to advertise a real estate development. But within a few years, as the silent-film era gave way to "talkies," the sign evolved into a popular tourist attraction. Falling into disrepair in ensuing decades—at the peak of its decay, the sign was missing its third "O" altogether—the original was demolished and a sturdier version built in 1978.Desktop Version
Summer winds down in the Southern Hemisphere
Summer winds down in the Southern Hemisphere
As we in the Northern Hemisphere prepare to greet spring, many in Australia are probably looking forward to the end of a punishing summer. Relatively temperate autumn weather must come as a relief to our friends Down Under. Some are likely greeting the change in seasons with a trip to the pool, like the swimmers in today"s image of the Bronte Baths, an ocean pool located in a Sydney suburb. While seaside swimming pools aren"t unique to Australia, this island country is known for its many oceanside pools, which provide sheltered spots for swimming in places where rocky shorelines and occasional shark attacks can make ocean swimming difficult or dangerous.Desktop Version
National Mushroom Month
National Mushroom Month
The humble mushroom may grow in some dark, hidden places, but this is its time in the spotlight. National Mushroom Month is celebrated each year in the month of September in the United States. That’s when the Mushroom Council, a group of commercial mushroom producers, takes advantage of the opportunity to educate people on all that fabulous fungi have to offer—especially the nutritional benefits. Mushrooms have long been associated with good health. In fact, early Romans referred to mushrooms as "food of the gods" and hieroglyphics suggest that ancient Egyptians linked the mushroom to immortality. In modern times, we"ve learned that mushrooms are a powerful source of vitamins and antioxidants. Which type of mushroom is your favorite?Desktop Version
Autumn’s swan song
Autumn’s swan song
Each fall thousands of tundra swans can be seen in the Mississippi River Valley—a migration corridor for many species of waterfowl. Birders in Minnesota may spot the tundra swans as they make their way to favored wintering grounds in coastal regions of the US. They travel in family groups of about a hundred, and if you can’t see them, you’re bound to hear them. Tundra swans are a noisy bunch—they have a high-pitched honking call and are especially vocal while foraging.Desktop Version
Let’s celebrate
Let’s celebrate
The citizens of Morton, Minnesota, are probably doing a repeat performance of this pyrotechnic display today as they join the rest of the US in a celebration of Independence Day. If you want to blow the minds of your family and friends at the barbecue, steer the conversation toward fireworks and casually drop this truth bomb: Gunpowder, the fuel that makes the fireworks explode, was invented in ancient China by Taoist alchemists who hoped to create an immortality elixir. That’s some dramatic irony, at least in hindsight. Be safe!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

Victory in Europe, 75 years ago
On May 8, 1945, thousands of people poured into the streets of Paris to celebrate the defeat of Nazi Germany and the end of World War II in Europe. This photo of the famous Avenue des Champs-Élysées was taken from atop the appropriately named Arc de Triomphe, looking east toward the distant Place de la Concorde and the Louvre. Victory in Europe (VE-Day) had come at last.Desktop Version
A crush in Lavaux
A crush in Lavaux
The "crush season," aka the grape harvest, has arrived in these picturesque Swiss vineyards. The steeply terraced vineyards of the Lavaux region along Lake Geneva"s northern shore produce grapes for some of the best wine in the country. The vine terraces can be traced back to the 11th century, when Benedictine and Cistercian monasteries controlled the area. A UNESCO World Heritage site since 2007, Lavaux is the largest contiguous vineyard region in Switzerland. It"s known for producing Chasselas wine, a light, delicate white wine that"s considered the ideal pairing with Swiss raclette cheese. Visitors enjoy hiking between the vines and wine tasting at local cellars in the villages along the lakeshore. We"ll toast to that!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
Beethoven s 250th
Beethoven s 250th
German composer Ludwig van Beethoven created melodies and harmonies we instantly recognize, even in this entertainment-saturated 21st century. Overcoming childhood abuse, hearing loss, romantic rejection, and bouts of depression and alcoholism, Beethoven channeled his stormy emotions into music that compelled audiences to viscerally feel what he felt. In the process, he helped end the regimented Classical era and usher in the Romantic period, when even the most flawed artists were sovereign.Desktop Version
Bay Marker Lookout, Sydney Olympic Park, Australia
Bay Marker Lookout, Sydney Olympic Park, Australia
It"s an easy, circular trail to the Bay Marker Lookout, but you have to make it under your own steam—sorry, no cars allowed. This is one of the five Sydney Olympic Park Markers, cone-shaped earth mounds installed for the 2000 Olympics in Australia. They are cleverly placed to look from the air like the Australian flag"s Southern Cross. From the ground, the Bay Marker gives a stunning full-360-degree view of Wentworth Common—a large grassy park—and the larger Olympic Park and stadium. You can also look over Homebush Bay (the community and the body of water) to the north. It"s a dramatic melding of urban landscape, the city skyline, the wetlands and greenery, rivers, and beaches.Desktop Version
A silent witness to history
A silent witness to history
About 25 miles southwest of Rouen, on the way to Paris, the ruins of Château Gaillard still stand over the Seine River. King Richard I commissioned the castle in 1196, when England occupied portions of modern-day France. The English and French fought for control of the castle for roughly 400 years—a span including the Hundred Years War—before Henry IV of France ordered it demolished. Today, the outer walls—called baileys—are open to the public year-round, while the inner baileys are open during summer months.Desktop Version
The island fox’s incredible comeback
The island fox’s incredible comeback
Meet the island fox, a petite resident of California’s Channel Islands National Park and a true comeback kid. The house-cat-sized creature is endemic to the islands, meaning it’s found nowhere else on Earth. In the 1990s, scientists observed the island fox population on Santa Cruz Island had dropped to fewer than 100 animals. The decline was attributed largely to golden eagles, who moved into new territory after bald eagle populations declined and found the island foxes to be easy prey. (Golden eagles are more prodigious hunters than bald eagles.) Environmental groups launched an effort to bring back the island fox, in part by relocating golden eagles, and by 2015, the population on Santa Cruz Island had rebounded to about 1,750. That’s good news for the fox–and for the entire island ecosystem. As the eagle situation demonstrated, most things in nature are interconnected.Desktop Version
A day for the oceans
A day for the oceans
The Galápagos sea lion is found in two places in the world—its namesake locale and the Isla de la Plata just off the coast of Ecuador. The expert swimmers are often spotted playing and surfing in the waves. They"re gregarious on land, too, sometimes even grabbing a snooze on a town bench. Although a common and beloved sight in the islands, Galápagos sea lions are endangered, and their numbers are susceptible to changes in ocean temperatures, which can limit their food supply.Desktop Version
