International Polar Bear Day
International Polar Bear Day
February 27 marks International Polar Bear Day—an effort to raise awareness of the enormous threats polar bears face due to climate change. Polar bears need Arctic pack ice to hunt on, but that ice is shrinking as the planet warms. While polar bears are excellent swimmers—so much so that they"re classified as marine mammals—the Arctic ice is still a crucial part of their survival. Let"s take this day to think about what we can do to help reduce climate change and protect polar bear habitats.Desktop Version
An uncommon look at an American icon
An uncommon look at an American icon
The tallest building in the world when it was completed in 1884, the Washington Monument was meant to capture the respect and gratitude American citizens have for our first president. The journey to build the obelisk was long and arduous, including a 23-year gap in the construction. According to Mark Twain, the incomplete monument looked like ‘a factory chimney with the top broken off.’ On this day in 1876 the Washington Monument was accepted into the National Park System, and today it’s one of the most recognizable buildings in the US.Desktop Version
Bobbio, Italy
Bobbio, Italy
Between the metropolis of Milan—the fashion and design capital of Italy—and the fabled seaport city of Genoa, you"ll find this small river town in northern Italy. People have resided here since ancient times, at least as far back as the Roman era, but the town really began to flourish when the abbey was constructed in the 7th century. For much of the Middle Ages, the Bobbio Abbey and its vast library made the town a center of religion, culture, and learning.Desktop Version
Time for brass bands and beer
Time for brass bands and beer
Our photo today shows the crowds at an Oktoberfest parade reflected in the bell of a brass horn. In Munich, Germany, the 16-day festival will include many brass bands marching and playing celebratory Bavarian folk music, while other bands will play for the beer drinkers in the tents and beer halls that dot the festival grounds. Why call it ‘Oktoberfest’ when it begins in September? The original Oktoberfest began on October 12, 1810, as a massive one-day royal wedding celebration open to the public. On October 12 the following year, Munich citizens commemorated the wedding with another party, and an annual tradition was born. The festivities grew longer and longer each year over the course of two centuries, and Oktoberfest eventually extended into the weeks before the original date. Organizers supported the earlier start to take advantage of better weather in late September, but the party will forever be known as Oktoberfest.Desktop Version
Cloughoughter Castle, County Cavan, Ireland
Cloughoughter Castle, County Cavan, Ireland
Cloughoughter Castle sits on a small island in the middle of Lough Oughter, a huge complex of lakes and waterways in County Cavan in Ireland. Its first stones are thought to have been laid in the early 13th century by the Anglo-Norman de Lacy family, but the O"Reilly clan took possession of the area in 1233 and completed the castle"s construction. They retained control of Cloughoughter Castle for centuries, but by 1653, it had been bombed and abandoned. Since then, it has been in ruins, resplendent in a sort of tattered grandeur. It can only be visited by boat but, as a symbol of Ireland"s medieval heritage, it is a must-see for history and castle enthusiasts alike.Desktop Version
Let s crack the code
Let s crack the code
If you"ve ever been the least bit curious about how computers work, this week is for you. December 9 marks the start of Computer Science Education Week, an annual program that uses the Hour of Code as one way to inspire K-12 students to take an interest in computer science and to level the playing field in an industry that can seem intimidating to some. The Hour of Code is exactly what it sounds like: Students and adults alike are invited to set aside 60 minutes to try out one of the many Hour of Code tutorials—offered in 45 languages—for a brief introduction to coding. Organizers believe every single student should have the opportunity to learn computer science, as it nurtures creativity and encourages problem solving. We concur. And we highly recommend the Minecraft tutorials as a starting place. Happy coding, friends!Desktop Version
Steyr River, Austria
Steyr River, Austria
These whitewater rapids are found in Upper Austria, where the Steyr River crashes down from the barren Totes Gebirge (the Dead Mountains) through this verdant landscape. When it comes to the ancient town of Steyr, at the foot of the Alps, it will meet the Enns River, which flows into the Danube.Desktop Version
A path to access
A path to access
Here"s an example of cutting-edge form meeting practical function. This snakelike bridge, the brainchild of famed architect Frank Gehry, provides a meandering and safe path over a busy thoroughfare that separates Millennium Park and Maggie Daley Park in downtown Chicago. With a gentle 5% slope, the 935-foot bridge is accessible for people who use wheelchairs or have trouble navigating stairs, and that"s the main reason why we"re featuring it on our homepage today. Thirty years ago to the day, President George H.W. Bush signed the Americans With Disabilities Act. This sweeping civil rights bill prohibits discrimination against people with disabilities at work, in school, and in public spaces. The resulting law meant that much of the country"s physical infrastructure, like this elegantly curving bridge, was required to accommodate people with disabilities.Desktop Version
Happy 300th, NOLA!
Happy 300th, NOLA!
Today, Jackson Square and other places in New Orleans will be full of revelers. No, it’s not a Mardi Gras do-over, it’s the city’s 300th birthday celebration. Sometime in the spring of 1718, ‘La Nouvelle-Orléans’ was founded by French investors. Since then, residents of the Big Easy have chosen May 7 as the day to celebrate the birth of New Orleans. Really, this city doesn’t need an excuse to throw a party, but this one’s going to be big.Desktop Version
Traffic jam on the caribou highway
Traffic jam on the caribou highway
Today we"re in Kobuk Valley National Park in Alaska to witness one of the world’s great annual migrations. Every spring, a quarter million caribou come together to form the Western Arctic Herd and pass north through the 1.8-million-acre park to their summer calving grounds in the Brooks Range and its foothills. Then in the fall, the caribou make the reverse trip, heading south back through the park to where they spend the winter in the Nulato Hills and the Seward Peninsula. One of the best spots to see the herd on the move is where it crosses the Kobuk River at Onion Portage. This area is a major archaeological site too. For thousands of years, the crossing has drawn native groups that rely on caribou meat, a tradition that continues to this day.Desktop Version
Pearl Harbor Remembrance Day
Pearl Harbor Remembrance Day
Today we"re in Hawaii to mark the 80th anniversary of the surprise attack on the US naval base in Pearl Harbor on December 7, 1941. The strike by Japan cost 2,403 service members and civilians their lives, injured 1,178 others, and thrust the US into WWII. The sailors you see here are standing on the deck of the USS Bowfin, a US Navy submarine that is now a memorial and museum moored in Pearl Harbor next to the Pearl Harbor Visitor Center.Desktop Version
Let s celebrate cephalopods
Let s celebrate cephalopods
For World Octopus Day, we"re lighting up your screen with a shot of a nocturnal octopus from the genus Callistoctopus in its larval stage. It was photographed on a night dive near the Big Island of Hawaii. You may not consider octopuses cute and cuddly, but they have charisma to burn. The highly intelligent species has been observed solving puzzles, unscrewing lids, and even using tools. One study recorded octopuses collecting discarded coconut shells and carrying them back to their dens to use as shelter. In another incident that made headlines, an octopus named Otto taunted staff at his aquarium by repeatedly crawling out of his tank to shoot water at the overhead lights, causing them to short-circuit. Octopuses aren"t all brains—they"ve got heart as well (three, in fact!). The more we learn about this species, the more impressed we are. Can"t every day be World Octopus Day?Desktop Version
Where the bearded reedling sings
Where the bearded reedling sings
Feeling a hint of fall in the air? This bearded reedling could be, but a drop in temperature isn"t a signal for it to fly on to warmer destinations. These songbirds belong to a resident species, which means most stay put in the marshes, from England to eastern Asia, where they thrive. Their diet changes with the seasons: In the summer, they dine on reed aphids, while during the colder months, reed seeds sustain them. This guy—and we know he"s a male due the distinctive black "mustache" stretching down his face—is perching in the Elmley National Nature Reserve in Kent, one of the largest bird reserves in England.Desktop Version

Looking back on 150 years of rail travel
In 1986, work began to convert an old rail yard in Scranton, Pennsylvania, from a relic to a heritage preservation site now known as Steamtown. A donated collection of train engines, some dating back to the 1800s, gave Steamtown exhibits to show off, while the fully functional rail yard provides a live demonstration of how trains work—and how rail transit greatly changed the United States.Desktop Version
Let’s go mothing
Let’s go mothing
In the Lepidoptera order of the animal kingdom, it’s butterflies who get all the glory. But we’d argue it’s their relatives, moths, that have the better story. With more than 160,000 species of moths around the world, moths outnumber butterfly species roughly 10 to 1. While most are nocturnal, the hummingbird hawk-moth on our homepage today breaks the mold. Found throughout Africa, Asia, and Europe, it’s shown here in the daylight of southern Sardinia, sipping nectar with its straw-like appendage known as a proboscis. Like a hummingbird, the moth makes a soft buzzing sound as it hovers over the flowers whose nectar it feeds on exclusively.Desktop Version

Who knew that an 800-year-old structure could look so festive? The pretty holiday illumination you see is adorning the side of the Palais de l"Ile, a distinctive 12th-century building in the town of Annecy, France, high in the French Alps. Designated a historic monument in 1900, the medieval structure is perched on a small islet in the Canal du Thiou.Desktop Version
Saint Andrews Day
Saint Andrews Day
Scotland"s fantastical landscapes are steeped in folklore and myths. The Old Man of Storr—a 164-foot rocky pinnacle on the Isle of Skye—is no exception. So named because it is said to resemble a craggy man when viewed from the right angle, it has long inspired tales of giants and magic. The Old Man towers over the Trotternish Ridge, a 20-mile-long landslip that is home to many stunning and strange rock formations, each with their own stories.Desktop Version
Is that a buzzing sound?
Is that a buzzing sound?
Why are dozens of colorful boxes stacked in this field? To provide homes inside their walls for millions of honey bees, those hardworking pollinators, producers of honey, and tormenters of Winnie-the-Pooh. Wild honey bee colonies build their nests in trees and caves, but manmade boxes also do the trick, and humans have been building their own beehives since antiquity. The modern beehive boxes shown here contain frames to hold honeycombs that bees produce to store their honey, pollen, and young. When the bees have produced plenty of honey, the beekeeper can simply remove the frames to extract some of it, leaving the rest to nourish the hive.Desktop Version
Ice and Snow Sailing World Championships
Ice and Snow Sailing World Championships
Today is the opening day of the WISSA Ice and Snow Sailing World Championships, which take place this year in Lithuania. Iceboating, also known as ice sailing, began in 17th-century Europe. Travelers used vessels on blades to traverse the frozen Gulf of Riga in the Baltic Sea and the iced-over canals of the Netherlands. These days, the sport is enjoyed as a recreational and competitive activity using a variety of boats, boards, skates, and kites. The world championships, which fall under the broader umbrella of windsurfing competitions, have been held since 1980. Good luck to all those out there competing for fame and glory on the windswept ice!Desktop Version
Reflections on the mighty Amazon
Reflections on the mighty Amazon
For World Rainforest Day we take you below these clouds to the Amazon River Basin and the largest rainforest in the world. Numbers help the story of this extraordinary place: At more than 2.1 million square miles, the Amazon accounts for half of Earth’s remaining tropical rainforests. And a fifth of the world’s fresh water flows through this river basin. Perhaps a tenth of the planet’s known species call it home, many of which have yet to be identified—that’s trees, plants, fish, mammals, and a third of Earth’s bird species. Now take a deep breath. The ‘Lungs of the World’ produces 20 percent of Earth’s oxygen, while storing vast amounts of carbon dioxide, earning it an all-star ‘carbon sink’ status.Desktop Version
Happy Father s Day
Happy Father s Day
These bald eagles look like they"re enjoying some family time on Father"s Day. But today is extra special for them, because it"s also American Eagle Day, a celebration that commemorates the date in 1782 when the bird was added to the Great Seal of the United States, effectively becoming a national symbol. With an olive branch in its right talons and a bundle of 13 arrows in its left (representing the 13 original states in the Union), the eagle is said to represent a strong desire for peace, but readiness for conflict. You"ll recognize the Great Seal of the United States from its appearance on passports, flags, official documents, and American currency.Desktop Version

No, that stone in today"s homepage image didn"t get there by itself. Or did it? Not only is Death Valley one of the hottest places on Earth, it also boasts a mysterious geologic phenomenon—rocks that drift across the exceptionally flat desert floor, seemingly under their own power. The rocks here at Death Valley"s Racetrack Playa are known as "sailing stones" and they can vary in size from a few ounces to hundreds of pounds. As seen in our image, the stones leave long trails behind them as they move across the scenic dry lakebed.Desktop Version
