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
Congratulations, 2019 Nobel Prize laureates!
Congratulations, 2019 Nobel Prize laureates!
This opulent room is the Golden Hall, a banquet hall in Stockholm City Hall, which will be one of the venues for today"s Nobel Prize award proceedings. The room, which is completely covered in mosaic tiles, includes representations of Swedish history and culture. Swedes refer to their capital as Mälardrottningen—the Queen of Lake Mälar—and our image depicts the queen with the city of Stockholm in her lap (the city lies between the lake and the Baltic Sea).Desktop Version
In the Himalayas for International Mountain Day
In the Himalayas for International Mountain Day
The steep, angular summit of Ama Dablam rises behind Tengboche Monastery, a Tibetan Buddhist site resting at over 12,000 feet. Ama Dablam means "mother"s necklace": Its swooping shape is thought to evoke a mother cradling a child, and a dangling glacier on its southwest face is believed to resemble the religious pendants many Sherpa women wear. Situated in the nearby Khumbu Valley, Tengboche Monastery is a stop on the Sacred Sites Trail Project, a self-guided trek through holy places that dot Nepal"s Sagarmatha National Park.Desktop Version
On the lookout for Sheep-Cote Clod
On the lookout for Sheep-Cote Clod
You"re looking at one of the oldest breeds of sheep in the world. Icelandic sheep are descended from short-tailed sheep brought to the island from Norway in the 9th and 10th centuries with the first waves of settlers. These sheep, with their dual-layer woolly coats, thrive in this harsh environment, outnumbering people in Iceland by more than 2-to-1. But on December 12, Icelandic sheep, especially the ewes, will have to contend with something more fearsome than the wind chill factor. Sheep-Cote Clod, the first of the 13 Yule Lads, is due to visit. Who"s that and what"s he up to? Take our quiz to find out.Desktop Version
Taking the scenic route
Taking the scenic route
Often called the most beautiful train ride in Switzerland, if not the world, the Bernina Express offers spectacular views on its sightseeing routes that connect towns in southeastern Switzerland to Tirano, Italy. It"s been in operation here since the late 1800s. The classic route takes about four hours and departs from Chur, Switzerland. Outfitted with panoramic windows, the train passes through 55 tunnels and over 196 bridges, some more than 100 years old, like the Landwasser Viaduct pictured on our homepage today. The cheerful red train winds its way up and over the Bernina Pass in the Alps, reaching an elevation of 7,392 feet. Pay special attention during the stretch from Thusis to Tirano—this portion of the route was designated a World Heritage site in 2008. Reservations recommended!Desktop Version
The Christmas Bird Count begins
The Christmas Bird Count begins
Today marks the start of the annual Christmas Bird Count, a bird census sponsored by the National Audubon Society that also happens to be the longest-running citizen scientist survey in the world. Each year the count runs from December 14 to January 5, giving bird lovers across North America a chance to join in, get outside, and spot some birds. The findings recorded by participants are collected and used to gauge the health of various bird populations. This information is then used to focus conservation efforts on particular species and geographical areas.Desktop Version
The Battle of the Bulge 75 years later
The Battle of the Bulge 75 years later
Seventy-five years ago this week, the Battle of the Bulge began in the forests of the Ardennes, Belgium. On the morning of Dec 16, 1944, the beleaguered German army threw its best remaining troops and armor against a lightly defended section of the Allied line. Bad weather neutralized Allied air superiority and over the first few days, the Nazi offensive produced a "bulge" in the Allies" defensive line west into Belgium. Desperate to hold the line, US General Eisenhower sent the 101st Airborne to defend the strategically important crossroads in Bastogne. The town was surrounded for nearly 10 days by German forces, but the Airborne held out. In fact, a German demand for Allied surrender was rejected with a single word: "NUTS" (a bit of 1940s American slang that needed to be explained to the Nazi officers). In the end, the German offensive was defeated, with US forces having borne the brunt of the fighting—Americans sustained their highest casualties of any single battle in World War II.Desktop Version

Cape Town at dusk
It"s a beautiful evening here in Cape Town, South Africa. From this vantage point we have a striking view of Table Mountain, with its "tablecloth," or cloud cover that typically shrouds the local landmark. Cape Town is a popular tourist destination noted for its beaches, natural beauty, architecture, and multicultural diversity—and in that diversity, it"s a showcase for the South Africa that Archbishop Desmond Tutu calls the "rainbow nation."Desktop Version
When in Rome...celebrate Saturnalia
When in Rome...celebrate Saturnalia
We"re looking at the Temple of Saturn, one of the oldest structures of the Forum in Rome. It was here that ancient Romans began their celebrations of Saturnalia, which started on December 17. Both the temple and the festival are dedicated to the agricultural god Saturn, whose reign was associated with a golden age of prosperity and peace. Saturnalia festivities kicked off with a sacrifice at the temple, followed by a public banquet and a week of general merrymaking. Activities included gambling, eating, drinking, and playing music. Businesses and schools closed, and even slaves were free from work and allowed to participate in the festivities. Many Saturnalia customs evolved into Christmas traditions, such as gift giving, decorating homes with wreaths, and drinking spiced wine.Desktop Version
It’s Weihnachtsmarkt time!
It’s Weihnachtsmarkt time!
The streets of this market square are all decked out in a tradition born nearly 700 years ago. Weihnachtsmarkte or Christkindlmarkte (Christmas markets, if you prefer less of a mouthful), take place around the world, but they originated in Germany as a celebratory way to observe Advent, the Christian season leading up to Christmas Eve. These markets are generally open-air affairs where everything is decorated, including the trees (called Tannenbaums in German if they"re firs). People shop from local artisans who sell their handmade wares in small wooden chalets. Then it"s off to eat traditional foods—roasted almonds, pastries, and biscuits—and sip on warm mulled wine.Desktop Version
Winter at Valley Forge
Winter at Valley Forge
Valley Forge, Pennsylvania, is the site of the winter encampment of the Continental Army under General George Washington. On December 19, 1777, about 12,000 soldiers and 400 women and children started to build 1,500 log huts where they would live for the next six months. At the time, the British were occupying the patriot capital of Philadelphia, just a day"s march away. Already two and a half years into the war, troops knew the harsh winter would stop the fighting, allowing them to organize and avoid mobilizing for several months. Life, however, was still challenging as they lacked funds for fresh food and clothing. There were no battles at Valley Forge, but nearly 2,000 people died from disease during the encampment.Desktop Version
Tree of many colors
Tree of many colors
Hold the tinsel—the rainbow eucalyptus tree doesn"t need decorations to appear festive for the holidays. Its bark displays a palette of bright colors by design. As older layers of bark peel away in strips, new layers packed with green chlorophyll are revealed. These exposed areas eventually transition to hues of blue, purple, and orange as tannins accumulate. The continual peeling allows the tree to shed mosses, lichen, fungi, or parasites along with the bark, while also exposing the chlorophyll underneath, which boosts the tree"s ability to photosynthesize. The bark isn"t the only unusual thing about this species. While most people associate eucalyptus with koalas and Australia, the rainbow eucalyptus is native to the Philippines and Indonesia. It thrives in tropical climates like Hawaii, where our homepage trees were photographed.Desktop Version
Seventeen arches at sunset
Seventeen arches at sunset
When it"s winter solstice time in the Northern Hemisphere, the setting sun shines under the Seventeen-Arch Bridge at the Summer Palace in Beijing, causing this romantic glow. In the 18th century, during the Qing dynasty of China, the Qianlong Emperor ordered the construction of this collection of gardens, lakes, and various structures, including temples and small palaces. These days, it"s one of Beijing"s premier attractions and sure to be crowded this time of year, with visitors headed to the bridge in time for sunset.Desktop Version

This macrophotograph of a snowflake shows the classic, six-sided structure that we"ve come to associate with the tiny winter marvels. Until the advent of macrophotography and microphotography in the late 1800s, it was impossible to study the structure of snowflakes—they melted too quickly to be accurately sketched under a microscope. Enter Wilson "Snowflake" Bentley.Desktop Version
A Festivus for the rest of us
A Festivus for the rest of us
We didn"t have a Festivus pole handy, so we"re bringing you near the South Pole, where two gentoo penguins seem to be sharing a loud "Airing of Grievances." December 23 marks Festivus, a tongue-in-cheek observance created by writer Daniel O"Keefe. At first an O"Keefe family inside joke, Festivus was rebranded as a rejection of Christmas-season commercialism and written into a 1997 episode of "Seinfeld" by Daniel"s son Dan. The show introduced such goofy new traditions as the "Airing of Grievances," "Feats of Strength," and identifying "Festivus miracles."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
Merry and bright
Merry and bright
Germans began decorating Christmas trees with candles as far back as the 1700s, but people wouldn"t begin stringing trees with electric lights until the late 1800s. Thomas Edison created the first practical incandescent lights and used them to decorate his Menlo Park laboratory for Christmas in 1880. Then three years later, the vice president of Edison"s company, Edward H. Johnson, had Christmas tree bulbs especially made, which he used to decorate the tree in his New York City home. Nevertheless, electric lights didn’t catch on as a holiday decoration among the general public until 1895, when President Grover Cleveland asked that the White House Christmas tree be illuminated by hundreds of multicolored electric bulbs.Desktop Version

Today we"re featuring an image of the Slovenian village of Praprotno and its Church of St. Thomas for the country"s Independence and Unity Day. On December 26, 1990, the results of a Slovenian vote on the country"s independence were announced. More than 95 percent of voters answered "Yes" to the question: Should the Republic of Slovenia become an independent and sovereign state?Desktop Version
Winterpret on ice
Winterpret on ice
These skaters in the village of Kinderdijk are embracing "winterpret," a Dutch word that means "winter joy" or "winter fun." Whenever temps drop low enough, many locals take to the ice and skate away on a complex network of canals. These waterways were built centuries ago—along with pumps, dikes, and the windmills pictured here—to protect the village of Kinderdijk by diverting water from the land. It"s an important job, since Kinderdijk, like much of the Netherlands, lies below sea level and flooding is a major problem. Nowadays a modern water management system with multiple pumping stations does the work, and the windmills are left with a new job–to maintain an iconic Dutch scene. In 1997, the Kinderdijk windmills were designated as a UNESCO World Heritage site.Desktop Version
Did they forget to fly south?
Did they forget to fly south?
Native to North America, trumpeter swans live near rivers, lakes, and coastal byways in northern and western US states in the lower 48, as well as in Canada and Alaska. Depending on where they live, these swans are either resident birds or medium-range migrators. What they all require, though, is year-round access to open water, since their diet consists almost entirely of aquatic plants. That may be why the swans in this image are drawn to the waters of Kelly Warm Springs in Wyoming, which won"t freeze even as snow lines the banks.Desktop Version

The annual tourney, which wraps up in early January, starts in the German towns of Oberstdorf and Garmisch-Partenkirchen, and then moves to Austria, with events in Innsbruck, like the qualification run in today"s image, and Bischofshofen.Desktop Version
Sky island views
Sky island views
Though it"s December, it isn"t cold and snowy everywhere in North America. Here, near Tucson, Arizona, the Sonoran Desert stays warm year-round. In this photo, we"re looking at a "sky island"—an isolated, high-elevation woodland surrounded by radically different lowland environments. In this case, the desert land at the base of the mountain is peppered with saguaros—a stately cactus recognized for its long arms. The snow-capped Santa Catalina Mountains in the distance are part of the Madrean Sky Islands and are home to Mount Lemmon Ski Valley, which is the southernmost ski destination in the US. The ski area covers the slopes of Mount Lemmon, which reaches an elevation of about 9,100 feet at the summit and can receive around 180 inches of snow annually.Desktop Version

3, 2, 1 … Happy New Year!
Backnang, the city celebrating the new year in this photo, is in Germany"s Baden region. Thanks to the Rhine River on the west, and the Black Forest to the east, the soil in Baden is ideal for vineyards. Among the varieties of wine produced here, Spätburgunder is popular, which you may know by its more common French name, Pinot noir. It seems likely that the people of Backnang would be celebrating with a glass of Pinot or something else this evening. However you choose to celebrate, here"s wishing you a very happy and healthy new year!Desktop Version
Napping away New Year s Day
Napping away New Year s Day
This mountain hare is starting the year off right. It"s used to cold weather and high altitudes—and, since it"s nocturnal, it"s perfectly comfortable sleeping through an afternoon snowstorm in northeast Scotland. On New Year"s Day, humans in the US are more likely to be found in their natural habitat, the couch, dozing off or perhaps watching one of the college football bowl games on TV. Some more ambitious folks might be getting a jump on their New Year"s resolutions and exercising. First Day Hikes are part of an initiative led by state parks, with hundreds of free guided hikes offered in all 50 states. That sounds great, but maybe a little later. Right now, we think the hare has the right idea.Desktop Version

Don"t be fooled by this frozen scene"s tranquility. Once the snow melts in northern Finland"s Oulanka National Park, the river"s gentle swirl will turn to deafening rapids, hosting rafters as well as waterfall-peeping tourists. But there"s time to enjoy the winter calm, since the region"s wintry cold regularly stretches into April or May.Desktop Version
