In the Highlands for Saint Andrew s Day
In the Highlands for Saint Andrew s Day
Clan Campbell built this castle on the shore of Loch Awe in the Highlands of western Scotland during the mid-15th century. Kilchurn Castle withstood numerous structural changes and battles, but it couldn’t survive a lightning strike in 1760, and by 1770 the roof was gone and the castle in ruins. In the summer, you can hike to the site and explore.Desktop Version
A treaty for science
A treaty for science
Twelve nations signed the Antarctic Treaty System on December 1, 1959, establishing the ice-covered continent as a place for scientific study open to all nations and banning any military activity there. Since then, additional countries joined in the treaty—now 53 nations participate in activities at the various research stations there. Our photo shows the northernmost part of Antarctica, the Antarctic Peninsula, south of Chile and Argentina.Desktop Version
Winter in Old Nuuk
Winter in Old Nuuk
It may not look like a bustling metropolis, but Nuuk is Greenland’s largest city and capital. Fewer than 56,000 people live in Greenland, and nearly a third of them reside in the modern comfort of Nuuk. Greenland is a constituent country of Denmark, and in Nuuk, the Danes have been a modernizing influence on the city, even here in Old Nuuk, a part of town established in the 1740s. Despite the Danish presence, the majority of Greenland’s population is Greenlandic Inuit. Nuuk began as a coastal fishing settlement, and much of Greenland’s commercial fishing fleet is still based out of the city’s harbor, which is also used as a shipping port.Desktop Version

Computer Science Education Week begins today, and because the field can seem daunting to the uninitiated, we’re showing a very relatable document that humanizes the work behind computer science. The notebook in this photo contains equations and ideas crafted by Alan Turing, the British mathematician and early computer scientist who helped the Allies win World War II when he cracked the code of Nazi Germany’s Enigma machine. In 2015, Turing’s notebook, written while he was working on the Enigma code, was sold at auction for more than $1 million.Desktop Version

The Sphinx Observatory isn’t the highest astronomical observatory on Earth, but it might feel like it to the lucky travelers who visit. To reach the observatory, they take a train up into the Alps, alight at Europe’s highest railway station, and ascend in an elevator tunneled inside the mountain. Once on top, stargazing is the academic focus, but visitors can take in sweeping views from the Sphinx’s 11,716-foot vantage. On either side are the Jungfrau and the Mönch, both members of the ‘four-thousander’ club—mountains that tower at least 4,000 meters (that’s 13,123 feet) above sea level.Desktop Version
’Chess on ice’
’Chess on ice’
Officially, summer began on December 1 here in New Zealand (where the first days of March, June, September, and December respectively are considered the start of autumn, winter, spring, and summer). But this icy view of Naseby, on New Zealand’s South Island, shows that harsh winters here offer great conditions for outdoor curling, or what competitors call ‘chess on ice.’ And when there’s a multi-game tournament going on, that’s a ‘bonspiel’ in curling lingo. This year marks the first ever Curling World Cup. The second leg of the four-leg event brings the curlers to Omaha, Nebraska, today through December 9. Canada’s teams won the first leg, in Suzhou, China. Will they face stiffer competition in the Cornhusker State?Desktop Version
The owl that loved football
The owl that loved football
As the name indicates, you’ll find the Eurasian eagle-owl across Asia and Europe. The eagle-owl in our photo today lives near Helsinki, Finland. Why an eagle-owl on Finnish Independence Day today? When Finland’s national team was playing a qualifying match against Belgium in 2007, an eagle-owl flew onto the pitch, delaying the game for several minutes. Ever since, the Finnish team has been nicknamed ‘Huuhkajat’—the eagle-owls. The owl, called ‘Bubi,’ was later named Citizen of the Year in Finland.Desktop Version
Honoring our fallen heroes
Honoring our fallen heroes
For Pearl Harbor Remembrance Day, we’re at the USS Arizona Memorial in Honolulu, a landmark that sees more than 2 million visitors each year. The memorial can only be reached by boat, since it straddles the sunken hull of the Arizona, which was bombed in the surprise attack on Pearl Harbor on this day in 1941. The event killed 2,403 Americans, and many of their names are inscribed here. The Arizona memorial is undergoing repairs this winter, but it’s slated to reopen to the public in March 2019. A commemoration ceremony is planned nearby for today’s observance.Desktop Version
How lovely are your branches
How lovely are your branches
While we are certainly fans of pretty lights and ornaments during the holidays, nothing could be lovelier than these evergreens in their natural setting, with just a dusting of snow. This wintry scene is from Two Jack Lake in the eastern part of Banff National Park, in Alberta, Canada. Banff, Canada’s oldest national park, is surrounded by other provincial and national parks, and together they make up a vast area of spectacular wilderness. Wintertime in this neck of the woods means plenty of skiing, snowshoeing, and if you’re lucky, glimpsing the northern lights.Desktop Version

There’s treasure in them thar hills
This wintry view comes from Oregon’s Painted Hills, part of the John Day Fossil Beds National Monument and home to one of the most complete fossil records on the planet. Paleontologists have uncovered fossils here that date as far back as 44 million years ago, when this region had a hot, wet, subtropical climate, home to crocodiles and rhino-like plant eaters. And what’s above ground here is equally impressive. This is only a glimpse of the portion of the monument called the Painted Hills, named for its vivid colors that are a result of layers of sediment from various geologic periods.Desktop Version

Bright red crabs like this one number in the tens of millions here on Christmas Island, a territory of Australia located in the Indian Ocean. It’s warm on the island this time of year, and these crabs are migrating to the sea, where they will mate and spawn. The event is quite a spectacle—onlookers will see rivers of crabs, thousands of them at a time climbing over fences and crossing roads on their journey, which attracts tourists to the remote destination. This isle itself was named by an English sea captain who discovered the destination on Christmas Day of 1643.Desktop Version
‘The mountains are calling’
‘The mountains are calling’
Mountains matter—that’s the message from the United Nations for International Mountain Day, observed on December 11. More than half the world’s population relies on mountains for fresh water, food, and clean energy. When mountain ecosystems are threatened by climate change and land degradation, it endangers not just plants and animals, but also the people who depend on mountains to survive. Here at Mount Kilimanjaro, viewed from Chyulu Hills National Park in neighboring Kenya, the peak’s shrinking glaciers and ice fields are being closely monitored by scientists.Desktop Version
The story of the poinsettia
The story of the poinsettia
The winter holidays are the poinsettia’s time to shine. Today, National Poinsettia Day marks the anniversary of the death of Joel Roberts Poinsett, the physician and botanist who first introduced the colorful plant to the United States in 1828. He discovered the plant while he was serving as the first US ambassador to Mexico, the plant’s native country, where Aztecs once used it to produce red dye. According to legend, the poinsettia’s association with Christmas began in 16th-century Mexico, where a little girl—too poor to buy a gift—gathered weeds from the roadside and placed them in front of a church altar. They eventually produced lovely red leaves alongside the green ones, and the poinsettia plant was on its way to becoming a Christmas tradition.Desktop Version
Iceland awaits the Yule Lads
Iceland awaits the Yule Lads
If you’re spending the holidays here in Reykjavik, be sure to keep an eye out for Sausage-Swiper, Window-Peeper, and Door-Slammer. They’re three of the Yule Lads, a group of 13 mischievous pranksters who—according to local folklore—visit homes one by one to leave rewards or punishments for children on each of the 13 days leading up to Christmas. Tonight, the Gully Gawk is scheduled for a visitation, waiting for an opportunity to sneak into the cowshed and steal milk. Modern versions of the lads sometimes portray them in a benevolent light, even dressed like Santa Claus, but other stories are dark. The lads are said to be the sons of Gryla, a mountain troll with an appetite for mischievous children. Let’s hope we’re on the nice list this year.Desktop Version
Time to count some birds
Time to count some birds
Before the 20th century, some North Americans organized ‘Christmas side hunts’ in which participants would choose sides, then compete to bag as many birds as possible. In 1900, ornithologist Frank Chapman suggested a bird census instead, and the Christmas Bird Count (CBC) was born. The annual count is sponsored by the National Audubon Society. This year, the CBC runs from today through January 5, 2019, giving citizen scientists across North America time to join in, get outside, and spot some birds. The data collected is 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

Holidays in the Venetian Lagoon
About a mile north of Venice, in the Venetian Lagoon, is a collection of seven small islands that lie so closely together they’re generally known as a single island called ‘Murano.’ Visitors cross the narrow canals of Murano via pedestrian bridges. And during the holidays, those canals are decorated with lights, making the whole scene even more romantic.Desktop Version

The Wright brothers documented the first sustained flight in a powered, controlled aircraft on this day in 1903. That historic achievement was the result of single-minded perseverance, study, and experimentation. The brothers had spent more than a dozen years designing, engineering, constructing, and tweaking various test craft, including groundbreaking work done on the glider shown here. Orville Wright snapped this photo of the plane as it’s piloted by his brother Wilbur, gliding down the slope of Big Kill Devil Hill in Kitty Hawk, North Carolina, in October 1902.Desktop Version
A hit ballet, long after its debut
A hit ballet, long after its debut
These days, Tchaikovsky’s ballet ‘The Nutcracker’ is an iconic holiday entertainment staple, produced by companies around the world. In this photo, the Moscow Ballet performs the seasonal crowd-pleaser in ToruĊ„, Poland. But when the ballet debuted this day in 1892 in St. Petersburg, Russia, it was not a hit. ‘The Nutcracker’ was revived and restaged in the early 20th century, but still didn’t make an impact. Then in 1944, the San Francisco Ballet performed the American debut of the ballet to great acclaim. It became a true Christmastime classic 10 years later, when choreographer George Balanchine staged his own 1954 production with the New York City Ballet. Balanchine’s version caught on and inspired other dance companies to stage it themselves. Today, ‘The Nutcracker’ is often such a draw that a staging of Tchaikovsky’s Christmas fantasy can help keep a ballet company financially stable.Desktop Version

This is just a glimpse of the elaborate light display at Nabana-no-Sato, a flower park located in the garden of Nagashima Spa Land in Kuwana, Japan. Millions of LED light bulbs are used here to illuminate the grounds and create shimmering pathways, tunnels, and patterns. Winter illuminations like this have grown in popularity at Japan’s parks, and they often stay up long after the holidays, providing a bright distraction from winter’s long nights.Desktop Version
Paper lanterns on the longest night
Paper lanterns on the longest night
For the winter solstice today, we’re in Santa Fe, where residents celebrate the holidays with lovely paper lanterns known as farolitos, or luminarias. The annual Farolito Walk takes place each Christmas Eve in the city’s Canyon Road arts district, but the farolitos are often on display much earlier, lighting the way among the pueblo-style architecture that this region is known for. Winter solstice marks both the official start of winter, and the longest night of the year—meaning these paper lanterns will be put to good use tonight.Desktop Version
Night of the ‘Cold Moon’
Night of the ‘Cold Moon’
Historically, many cultures have looked to the moon rather than the sun to help track the months and seasons—and they adopted special names for full moons throughout the year. That’s why, in the Northern Hemisphere, a full moon that appears in December is known as the Cold Moon, according to the Old Farmer’s Almanac, a nod to the chilly temperatures of winter. Various American Indian tribes have given it equally descriptive names, including the Long Night Moon, as it occurs near the winter solstice. Other Native American terms include Oak Moon, Big Spirit Moon, and Snow Moon. The Cold Moon of 2018 rises this evening about 15 minutes after sunset. And in case you’re wondering, the moonrise on our homepage image today was photographed over the Thunderer, a mountain in Yellowstone National Park, in Wyoming.Desktop Version

The birthplace of a classic Christmas carol
The birthplace of a classic Christmas carol
All is calm here in Salzburg, Austria, tonight–much like we imagine it was on this day 200 years ago, when the song ‘Silent Night’ made its debut in the world. This is the bicentennial of the popular carol, written by Franz Gruber and Joseph Mohr, and first performed in a chapel in the nearby town of Oberndorf. The song has since been performed by artists around the world and was given intangible cultural heritage status by UNESCO. But the most popular recording of the song belongs to Bing Crosby, whose rendition remains the third best-selling single of all time.Desktop Version
