The Old City of Bern
The Old City of Bern
Welcome to a wintry wonderland in Bern, the capital of Switzerland. We"re in Bern"s medieval center—the Old City—which looks much as it did when many of these buildings were constructed between the 12th and 15th centuries.Desktop Version
Groundhog Day
Groundhog Day
Groundhog Day is a North American tradition with roots in the February 2 Candlemas observance practiced by German immigrants. The most well-known Groundhog Day celebration, in Punxsutawney, Pennsylvania, was first promoted by a local newspaper editor in 1886. Thousands of people gather in Punxsutawney each year to witness the groundhog emerge from its burrow, and more importantly, to see if the critter spots its shadow. If it does, winter will go on for six weeks, according to tradition. If it does not, spring-like conditions are said to be coming. Studies have yet to prove any link between the two events, but that hasn’t cast a shadow over this unusual tradition, which remains as popular as ever in the 21st century.Desktop Version

We"ll be the ones to drop the news on you: It"s Asteroid Day! Today you"re invited to explore a realm of science usually encountered only through white-knuckle action flicks: asteroid impact avoidance, or the study of what the heck we do if we spot a big chunk of space junk hurtling right at Earth. That"s right, don"t worry: People somewhere are coming up with plans for this.Desktop Version
Wind horses carry wishes for a new year
Wind horses carry wishes for a new year
For the first day of Losar, or the Tibetan New Year, we"re paying a visit to these Buddhist pilgrims at the Ganden Monastery in Lhasa, Tibet. Losar is celebrated for 15 days, but most events occur in the first three days. They include wishing family members a prosperous year, praying at monasteries or temples, exchanging gifts, burning incense, chanting, wrestling, horse racing, and more. Celebrations for the new year end with Chotrul Duchen, or the Butter Lamp Festival. The pilgrims in today"s image are releasing prayer flags called "wind horses" or lungtas, a ritual they perform for Losar and during the rest of the year as well. Upon releasing the prayer flags, the pilgrims ask the mountain deity to "increase their fortune like the galloping of a horse and expand their prosperity like the boiling over of milk."Desktop Version
Llama Day
Llama Day
Prick up your ears and crane your neck—it"s National Llama Day. Part of a family that includes camels, alpacas, and guanacos, llamas have long been domesticated in South America because of their hardiness and ability to thrive on the bleak vegetation in the mountains and plateaus of the Andes. At up to 6 feet tall and weighing up to 400 pounds, they were used primarily as pack animals for about 6,500 years. They were also bred as a source of food, hides, tallow for candles, dung for fuel, and fabric. While inferior to alpaca and guanaco wool, llama fleece is soft, warm, durable, and fairly lightweight. It"s used for clothing, rugs, and rope.Desktop Version
The Spirit of Harlem by Louis Delsarte
The Spirit of Harlem by Louis Delsarte
On International Jazz Day, we"re looking at "The Spirit of Harlem," a glass mosaic mural by artist Louis Delsarte. Located near the legendary Apollo Theater in New York City"s Harlem neighborhood, it depicts, among others, jazz greats Cab Calloway and Count Basie. Originally commissioned in 2005, the mural was covered up in 2017 when a new store moved into its location. After a petition and protests, the retailer worked with Delsarte to restore the mural and add a new plaque dedicating it to the Harlem community. Delsarte, whose other works include a 125-foot-long mural at the Martin Luther King Jr. Natatorium in Atlanta, died in May 2020.Desktop Version
Plitvice Lakes National Park in Croatia
Plitvice Lakes National Park in Croatia
In a country more famous for its coastline, about a million visitors each year venture inland to amble along these boardwalks and marvel at spectacular lakes and mountains. Plitvice Lakes National Park is the oldest and largest of Croatia"s national parks. The big attraction is the series of 16 descending, turquoise-colored lakes, connected by subterranean karst rivers, and above ground by streams and waterfalls. The lakes are separated by natural dams of travertine, which is created by the interplay of water, plant material, and bacteria. The water changes color from green to azure to gray depending on the angle of the light and the density of minerals and organisms in the water. About 11 miles of wooden boardwalk make it easy for people to wander among the lakes, falls, and caves that are open to visitors year-round.Desktop Version

International Tiger Day
International Tiger Day
It"s International Tiger Day! A day to celebrate these magnificent animals and consider how best they can be protected. The largest wild cats in the world, all tiger species are endangered, facing challenges including habitat loss, the illegal wildlife trade, and poaching. The Bengal tiger, an iconic subspecies primarily found in India, is the star of today"s image. As apex predators, Bengal tigers play a vital role in maintaining ecological balance by controlling populations of deer, wild boar, and bison. With an estimated population in the wild of between 2,500 and 3,000, tiger conservation is crucial to secure the future of this majestic species.Desktop Version
The Alhambra in Granada, Spain
The Alhambra in Granada, Spain
The winds of history have long blown through the beautiful halls of the Alhambra. Though it had been the location of fortresses as far back as the 800s, construction of the Alhambra (Arabic for "red castle") began in 1238 under the rule of Muhammad I Ibn al-Ahmar, founder of the Emirate of Granada. Ensuing leaders would continue construction of the complex, turning it into one of the finest examples of architecture from the historic Islamic world. The palace was the final hold of the Moors before the completion of the Christian Reconquista in 1492, when the Alhambra became the royal court of Ferdinand and Isabella. They greeted Christopher Columbus there later that same year.Desktop Version
Notes from an underground lake
Notes from an underground lake
The Ruskeala Mountain Park is an eerily beautiful reminder of the booming mining industry that thrived for centuries in this area of Russia near the border with Finland. Located on the site of an abandoned marble quarry, the park opened to the public in 2005. The centuries-old quarry has been flooded with groundwater since the end of World War II, although some old buildings and kilns from the mines are still intact.Desktop Version
Aprils full moon
Aprils full moon
The full moon has inspired folklore, myths, writers, and artists throughout history and has been given many names, depending on the time of year it appears. April"s first full moon is known as the pink moon, but that doesn’t mean it will appear pink against the night sky. Native Americans named it for the pink wildflowers, moss pink or creeping phlox, that bloom in the eastern US in the spring.Desktop Version
Beyond Walls for World Refugee Day
Beyond Walls for World Refugee Day
For World Refugee Day, we"re featuring an aerial view of "Beyond Walls," an art installation by the French artist Saype. In the span of five years, he aims to create the longest symbolic human chain around the world by constructing outdoor designs of interlaced hands just like this in over 20 cities. The first four were completed in 2019 in Paris, Andorra, Berlin and Geneva, Switzerland, shown here.Desktop Version
Paleontology meets art
Paleontology meets art
Though it looks like a fresco from ancient Greece, this is the fossilized remains of a fern found in Córdoba, Spain. The fossil dates back to the Carboniferous period, roughly 350 million years ago. This is a "compression fossil"—where a small amount of the original plant material was retained with the mineral deposits that helped form the impression. Why all the paleobotany talk? It"s National Fossil Day, and we’re excited! Whether you make a trip to your local natural history museum, trek off to a national park with a fossil exhibit, or just look at fossil photos on the web, we hope you find a fun way to celebrate National Fossil Day.Desktop Version
The lights of Paris
The lights of Paris
As twilight turns to night, the city of Paris lights up. Streets and buildings are bathed in light, alongside grand monuments such as the Hôtel National des Invalides, whose famous dome shines out in our homepage image. It was built during the 17th century under Louis XIV, as a hospital and home for army veterans. It was also Louis XIV, known as the Sun King, who ordered streetlights to be erected throughout the city to light up dark alleys where lawbreakers might lurk. Parisians were also asked to put up lanterns and oil lamps, and place lit candles in their windows.Desktop Version
National Lighthouse Day
National Lighthouse Day
Happy National Lighthouse Day! A beacon, a warning, and a symbol of hope and home, lighthouses have existed for thousands of years. The earliest known was the Pharos of Alexandria, which stood an estimated 330 feet tall. Built by the ancient Egyptians in the 3rd century BCE, an open fire was lit at its highest part to guide ships into port. Illumination technology advanced over the centuries, culminating in today"s electric versions beaming light that can be seen from over 20 miles away. North Carolina"s Bodie Island Lighthouse, pictured here, was built in 1872 and overlooks a section of ocean once known as the Graveyard of the Atlantic. Since then, it"s been doing its best to outshine the stars above, as it guides sailors home to safe harbor.Desktop Version
International Day for Monuments and Sites
International Day for Monuments and Sites
Located high in the Andes Mountains, Peru"s Machu Picchu is believed to have been an estate for the Inca emperor Pachacuti, who ruled in the mid-15th century. This "Lost City of the Incas" is one of the world"s most famous archaeological sites, an engineering marvel, built without mortar, metal tools, or the wheel. As an icon of Inca civilization, it is a perfect fit for UNESCO"s International Day for Monuments and Sites, which has been celebrating important cultural heritage sites for 40 years. Landmarks such as the Pueblo Indian dwellings of Mesa Verde, the Taj Mahal, the Great Pyramid of Giza, and the Parthenon give us the opportunity to look back at the cultures that came before us and preserve their memory for future generations.Desktop Version
Celebrate Mandela Day
Celebrate Mandela Day
Today we’re in Howick, a town near the east coast of South Africa, where this monument honors the anti-apartheid activist and South African president Nelson Mandela, who would have turned 100 today. Like Martin Luther King Jr. Day in the US, Mandela Day—celebrated on Mandela’s birthday—is intended not as a holiday exactly but as a day to answer the ‘global call to action’ by finding ways to engage in service to your local community. The best part about Mandela Day? You don’t need to be from South Africa to observe the event.Desktop Version

Mountain hare hopping into Lunar New Year
Today is the start of the Lunar New Year, which ushers in the Year of the Rabbit. Those born under the sign of the rabbit are believed to be ingenious, sweet, happy, quiet, and persistent. Famous rabbits include Albert Einstein, Frank Sinatra, Lionel Messi, and Ingrid Bergman. The Lunar New Year celebration starts with the first new moon in January and goes for the next 15 days, until the year"s first full moon lights up the night sky. Historically it has been an occasion for feasting and honoring deities as well as ancestors. We"re doing our part by sharing this lovely winter image of a mountain hare in Derbyshire, England.Desktop Version

Those brave enough to step out over this suspension bridge will be treated to a macaw"s-eye view of the Amazon rainforest, on which the survival of life on Earth depends. The vast Amazon biome, which spans 2.6 million square miles—an area twice the size of India—stores enormous amounts of carbon and supports approximately 10% of all known animal and plant species on Earth.Desktop Version
Swim city
Swim city
Switzerland may be a landlocked country in the middle of Europe, but with about 6% of Europe"s fresh water flowing through its countless rivers and lakes, there are plenty of outdoor swimming spots to cool down in the Swiss summer heat. Today, we"re dipping our toes in the pristine waters of Lake Zürich in Switzerland"s largest city, which has developed its own urban lido culture. Dotted across Zürich, you"ll find lots of lidos (public open-air swimming pools or bathing beaches) that make the most of the city"s lakes. This time of year, it"s common to see bankers and other workers change from business suits into bathing suits as they enjoy a quick swim during their lunch break.Desktop Version
A little blue
A little blue
If you want to see a little blue heron in its natural habitat, head to the swamps, tidal flats, and lake marshes of the US Gulf Coast, the Caribbean Islands, and Central America—and bring your patience. These herons keep a low profile, and often sit so still while hunting, they can be hard to spot. The adults develop deep blue plumage, sometimes sporting purple feathers on their heads, and tiptoe around the shoreline on green legs. The chicks are born snowy white, which scientists suggest is a survival adaptation to help them blend in with cattle egrets and snowy egrets—both species with bright white feathers—to enjoy the added safety of being in a large group.Desktop Version

It s aboat time for the Barcolana
Today we"re featuring an image of the Barcolana regatta, which is happening this weekend off the shore of Trieste, Italy. What makes this race so unusual—and so popular—is that it"s open to both professional and amateur sailors. Its beginning was fairly inauspicious—in 1969 only 51 boats sailed in the inaugural race. But it"s been drawing increasing numbers of sailors and spectators to Trieste each year. Last year, for the 50th anniversary of the Barcolana, 2,689 yachts raced the course and set the official record for largest sailing race in the world. Featuring a youth sailing race, an open-water swimming race, a night sailing race, music concerts, food and wine tastings, and many other events, the Barcolana offers opportunities for landlubbers and sea dogs alike to enjoy themselves during the regatta.Desktop Version
