It s tree-climbing season
It s tree-climbing season
These cheetah cubs in the Ngorongoro Conservation Area in Tanzania are playing and chasing each other. While doing this, they"re also developing the skills they"ll need to protect themselves and hunt for food. Cheetahs are born with all their spots, but at birth those spots are closer together, giving the cubs a darker appearance that helps them hide from predators. They also have a strip of long fur down the center of their backs called a mantle that helps them blend into the grass. June is an optimal month for wildlife viewing in the Ngorongoro Conservation Area since it"s the start of the dry season. In addition to cheetahs, visitors can spot lions, hyenas, leopards, jackals, and other animals.Desktop Version
The National Museum of the American Indian
The National Museum of the American Indian
Today, on the first day of Native American Heritage Month, we’re visiting the National Museum of the American Indian (NMAI) in Washington, DC. It"s part of the large network of the Smithsonian Institution, and has branches in New York and Maryland. Together, the three museums share one of the world"s largest collections of Western Hemisphere Native artifacts, "from the Arctic Circle to Tierra del Fuego."Desktop Version
Remembering Krakatoa
Remembering Krakatoa
Over two days in late August 1883, Krakatoa—an uninhabited island near Indonesia—experienced one of the most destructive volcanic eruptions of modern times. Ten times more powerful than the eruption of Mount St. Helens, it obliterated all but a third of the island and triggered massive tsunamis. The biggest blast could be heard 3,000 miles away—it’s still the loudest sound ever recorded. More than 36,000 people lost their lives, and the explosions impacted the entire world for years: Global temperatures dropped and skies darkened, causing huge crop failures. Sunsets turned a vivid red and the moon often appeared blue or green after the event due to the volcanic debris circling in the atmosphere.Desktop Version
Autumn in the cypress swamp
Autumn in the cypress swamp
Autumn still brings a splash of color to this hardwood forest of bald cypress in Louisiana. But make no mistake, a stroll through these wetlands is not a cozy New England leaf-peeping journey. The swamp forest floor is often covered by the waters of the Atchafalaya River delta as it drains into the Gulf of Mexico, so the autumn colors here are best viewed from the seat of a canoe or a pirogue, as the local Cajuns use. The water-resistant bald cypress trees thriving in the Atchafalaya Basin constitute the largest tract of contiguous cypress forest in the United States. The ecosystem here is so unlike any other in the US, the Atchafalaya National Heritage Area organization calls it "America"s foreign country."Desktop Version
A giant relic in Java
A giant relic in Java
This photo shows the quiet, mist-shrouded wilderness surrounding the Buddhist temple known as Borobudur. The site is among the most-visited attractions on the island of Java, with devout practitioners making pilgrimages to the holy site and curious tourists coming to see the grandeur of the structure. With 504 Buddha statues and 2,672 sculpted relief panels, Borobudur is the world"s largest Buddhist temple. It was likely constructed in the 9th century and abandoned in the 14th as much of the Indonesian population converted from Buddhism and Hinduism to Islam.Desktop Version
Swinging into International Jazz Day
Swinging into International Jazz Day
You are seeing–and hearing, if you click the audio button on the lower-right corner of the homepage–the musical stylings of Mary Lou Williams, often called the first lady of the jazz keyboard. Williams was a composer, arranger, and pianist who recorded more than 100 records, collaborating with the likes of Dizzy Gillespie, Thelonious Monk, and Duke Ellington. She’s photographed here in 1943 by photographer Gjon Mili, who often hosted jazz jam sessions at his New York City studio.Desktop Version
A city of bridges
A city of bridges
We"re in the heart of Switzerland looking down on the compact city of Lucerne, in a charming waterfront setting along the shores of its namesake lake and the River Reuss. Surrounded by snow-capped mountains just out of frame, Lucerne lies in the German-speaking part of central Switzerland and is divided into two parts linked by a series of bridges. The most famous of these bridges—the centerpiece and symbol of Lucerne—is the Kapellbrücke (Chapel Bridge), a covered wooden footbridge that you can see spanning diagonally across the Reuss in our photo. The building rising from the river alongside the footbridge is a medieval water tower, which has been used as a prison, torture chamber, local archive, and treasury.Desktop Version
Kangaroo family for National Hugging Day
Kangaroo family for National Hugging Day
Whether you call it a hug or an embrace, there is something about the power of touch that all mammals can relate to. Take this mommy kangaroo and her joey for example—no words are needed to convey what is going on in this image. Not only does this cute pair give us the warm and fuzzies, it"s also a perfect visual for National Hugging Day, which we are celebrating today. This warm-hearted occasion was created in 1986 by a man named Kevin Zaborney, who chose Jan 21 because it fell after the run of year-end holidays, landing right in the middle of winter when spirits tend to be low. That makes perfect sense to us! After all, hugging has been an essential part of the human experience for thousands of years. And studies have shown that it reduces stress, too. So find yourself a willing partner today and hug it out. You"ll feel better, we promise.Desktop Version
Citizenship Day and Constitution Day
Citizenship Day and Constitution Day
Today we visit the National Archives in Washington DC, where the US Constitution and the Declaration of Independence are on display, to mark Constitution Day and Citizenship Day. It"s a single day with a dual purpose—commemorating the formation and signing of the Constitution, while also recognizing both naturalized citizens and those born in the US. Ordinarily, many people become naturalized citizens in group ceremonies on this day; on average, about 700,000 people become American citizens each year.Desktop Version
Mount Logan in Yukon, Canada
Mount Logan in Yukon, Canada
Today we"re visiting Canada"s tallest mountain, the 19,551-foot-high Mount Logan, which is part of the St. Elias Mountain range. Located in Yukon, the smallest and westernmost of Canada"s three territories, this majestic peak is also the second tallest in North America—only Alaska"s Denali is taller.Desktop Version
International Museum Day
International Museum Day
On International Museum Day, we"re looking at the Centre Pompidou Málaga in Spain, an offshoot of the modern art museum in Paris. This location was introduced in 2015 as a pop-up branch—a temporary, underground space for exhibitions and multi-disciplinary experiences as well as workshops dedicated to younger audiences. Originally scheduled for a five-year run, it was extended until 2025. The piece we see here, "El Cubo," created by French artist Daniel Buren, is the only part of the museum that"s visible above ground. The glass cube functions as a multicolored skylight, its panels projecting tinted light into the subterranean museum"s courtyard below.Desktop Version
Dance of the egret
Dance of the egret
They say, "Dance like nobody"s watching," but here in Florida, this reddish egret could very likely have an audience of birders. The species has a reputation for bold, energetic feeding behavior that can resemble a frenetic dance. As it stalks its prey in shallow water, the reddish egret is prone to prance, stagger, and leap, while strategically positioning its wings to block the glare of the sun and boldly stab at fish. It"s one of many species that make Florida a year-round delight for birdwatchers.Desktop Version
Monarch butterflies migrate south
Monarch butterflies migrate south
Fall sets in motion a journey of some 3,000 miles for these monarch butterflies, which migrate from southern Canada to their wintering habitat in central Mexico. There, they cluster together in fir trees, creating the illusion of orange, fluttering foliage. They’ll remain in their winter roosts until March, when the journey back north begins. But no one individual monarch will complete the full roundtrip, which exceeds the normal monarch lifespan; instead it will take four generations of monarchs to complete the full migration, each individual seemingly driven by an internal compass that guides its flight path.Desktop Version
Celebrating the Day of the Dead
Celebrating the Day of the Dead
Whether made of wood, clay, or even candy, Day of the Dead skeleton figures, called calacas, share one common trait: They’re having fun. The reason for the whimsical portrayal of death is a holdover from the Aztec influence on Mexican culture. According to traditional beliefs, the dead don’t want to be remembered with sadness, but rather with the joy they brought to the world when they were alive. Today is the height of the three-day celebration, which begins with All Saints Eve on October 31, continues with All Saints Day (today), and ends with All Souls Day on November 2.Desktop Version
Wild scene on the Merced River
Wild scene on the Merced River
This stretch of the Merced River has been officially designated "wild and scenic" by the federal government. The Wild and Scenic Rivers Act was signed October 2, 1968, by President Lyndon B. Johnson to preserve rivers with "outstanding natural, cultural, and recreational values in a free-flowing condition for the enjoyment of present and future generations." It covers 13,416 miles of streams and protects parts of such natural treasures as the Allagash, Salmon, Snake, Trinity, and Missouri, which is the longest river in the US.Desktop Version

Celebrating Bike to Work Week, May 14-18
If you need some inspiration for National Bike to Work Week, we present the racers of the Maratona dles Dolomites road race. The most dedicated of these competitors will pedal over seven mountain passes as they ride 85 miles through the Dolomite mountains of Italy. But hey, even if you’re simply biking a few miles in honor of Bike to Work Week, we commend you. The event is sponsored by the League of American Bicyclists, a group that touts the many benefits of cycling–good health, strong communities, and a healthy environment.Desktop Version
A picture-perfect day on Trillium
A picture-perfect day on Trillium
Today we"re out on Trillium Lake, a manmade lake in the shadow of Mount Hood, Oregon"s tallest peak. Formed in 1960 by damming a tributary of the Salmon River, Trillium Lake"s a popular spot for fishing, camping, and boating. In springtime, the surrounding woods are filled with trilliums, the native flowering plants the lake"s named for. Take the flat, 1.9-mile loop trail around the lakeshore for stunning views of Mount Hood. But don"t stop there. Mount Hood National Forest has more than 1,200 miles of hiking trails, not to mention year-round skiing at higher elevations. Wrap up your day at the Timberline Lodge, built during the Great Depression by the WPA and now a National Historic Landmark. Bonus fact: Timberline Lodge was used for exterior shots of the Overlook Hotel in the horror movie "The Shining." But don"t let that scare you off visiting.Desktop Version
Ancient storage in the Grand Canyon
Ancient storage in the Grand Canyon
Around 1100 CE—a good 400 years before Spanish conquistadors would first glimpse the Grand Canyon—Ancestral Puebloans tended terrace farms along the banks of the Colorado River. In order to store their crops during the rainy season, when floods might destroy food stores, and to keep animals from eating the harvest, they created the Nankoweap Granaries high up in the canyon walls.Desktop Version
3,000 years of history
3,000 years of history
These massive temples—known today as Abu Simbel—were built in the 13th century BCE by the pharaoh Ramesses II. He left a legacy of monuments and temples across Egypt, many of which, like Abu Simbel, featured Ramesses II himself as the star attraction. But over the centuries, these temples were almost completely buried in sand and forgotten. It was not until the early 1800s when an explorer saw the heads of the colossal statues poking through the sand that the temples were again discovered. Then in the 20th century, construction of a dam on the Nile River formed Lake Nasser, a massive reservoir that would have flooded the site where the temples stood. To save them from inundation, the temples were disassembled and relocated to a nearby hill. The process took almost five years and required that workers cut the temples into pieces and reassemble them exactly as they were built 3,000 years ago. We think Ramesses II would approve.Desktop Version
It s time to fall back
It s time to fall back
While today"s image may look like a scene from the "Doctor Who" TV show, it actually shows workers maintaining Big Ben"s clock face. But like the Doctor, the show"s main character, today we"re all time travelers. This morning we fell back (or will fall back for night owls and insomniacs reading this before 2 AM) in time an hour for the end of daylight saving time. And like changes to "Doctor Who," this shift isn"t without controversy. Since the 1970s, many studies have tried to quantify the advantages or disadvantages that come with falling back and springing forward, but as yet there"s no definitive answer.Desktop Version
A day to take a moment
A day to take a moment
"A field of water betrays the spirit that is in the air. It is continually receiving new life and motion from above. It is intermediate between land and sky." So Henry David Thoreau immortalized Walden Pond, but he could have been describing this calming image of Ežezers Lake in Latvia. Today, the birthday of that famous American advocate for pursuing a simple life is also National Simplicity Day, an annual reminder to unplug, slow down, step back, and consider your life. Thoreau"s most famous work (that you probably haven"t read since high school), "Walden," is his account of the two years, two months, and two days he spent away from society in a cabin near the shore of Walden Pond in Concord, Massachusetts. Through this work he encourages us to take a step back and look for ways to simplify our lives. "Our life is frittered away by detail," Thoreau observed. "Simplify, simplify."Desktop Version
Take this for a spin...
Take this for a spin...
In 1851, when French physicist Léon Foucault performed his pendulum experiment in Paris, he became the first to prove what many scientists of his day already suspected—that the Earth spins on an axis. He conducted his first experiments 170 years ago, in early January 1851, with a relatively small prototype in the cellar of his home. Just a month later, Foucault performed his most famous pendulum demonstration, using a 62-pound spherical weight attached to a 220-foot wire, which was hung from the dome of the Panthéon, a Parisian monument. As the pendulum swung back and forth in a fixed plane, the pointed end of the weight traced lines in a compass-like circle of sand below it. As time passed, the angle of these lines began to change, demonstrating to onlookers that the Earth itself was rotating underneath the pendulum, and by extension, everyone watching was rotating as well, spinning on the surface of the great blue marble around its axis.Desktop Version
Dashing through the snow
Dashing through the snow
While many associate reindeer with the wonder of the holidays, these animals are magical in their own way. Known in North America as caribou, reindeer are well adapted to live in cold, rugged Arctic regions, like northern Norway where this herd was photographed. They"re built to withstand frigid temperatures with the help of thick, dense fur and noses that warm the air before they breathe it in.Desktop Version
What kind of bird laid these eggs?
What kind of bird laid these eggs?
These colorful little eggs are the progeny of the hoary redpoll, also known as the Arctic redpoll because of its extreme northern habitat. This hardy finch spends much of its time, including breeding season, in the brushy tundra of the northern polar regions. Because of the extreme cold, the female will often line her nest with feathers, particularly white ptarmigan feathers, as these appear to be. Sighting a hoary redpoll is a rare treat. The bird doesn"t exactly migrate, but in winter it will sometimes fly short distances farther south in search of food, so if you live in Minnesota, North Dakota, or Montana, you might get a peek at one on your bird feeder. You’ll recognize a hoary redpoll by its small yellow bill, red cap, dark face, and "frosty" white underbody streaked with brown. Or listen for the "chif chif chif" of its call.Desktop Version
Juniper Springs, Florida
Juniper Springs, Florida
Yes, the water here is as inviting as it looks: clear as glass, the shade of a precious gem, and a perfect 73 degrees every day of the year. Set within a subtropical forest, Juniper Springs is one of Florida"s oldest and best-known recreation areas, established in the 1930s as a place to camp, hike, and swim. Long before Disney arrived, natural springs like this one were the big draw in the Sunshine State.Desktop Version
