Dec 6, 2023Computer Science Education Week

Computer science is a dynamically developing discipline that has revolutionized our lives within a few decades. For Computer Science Education Week, we celebrate information systems and their power to connect the world, 24 hours a day. Where better to mark the occasion than the European Organization for Nuclear Research, known as CERN—birthplace of the World Wide Web? The 89-foot ball seen on today’s homepage is CERN"s Globe of Science and Innovation in Switzerland, in which visitors can learn more about the organization"s research work on particle physics. Quiet observers can wander around exhibitions and follow guided tours, and curious minds can take part in lab workshops and science shows for a first-hand experience.Desktop Version

Jul 31, 2019Go climb a tree

This egg-shaped observation tower in Germany’s Bavarian Forest National Park is part of one of the world’s longest canopy trails—and one of the most distinctive. Visitors reach the tower via a nearly 1-mile-long elevated walkway that winds around the tops of firs, beeches, spruces, and more at eye-level. From the 144-foot tower, built over three ancient fir trees, they can see the vast expanse of Bavaria’s forests and countryside. Not only do canopy walkways like this one give visitors a bird’s-eye view of the forest, they also allow people to experience nature without harming it.Desktop Version

Dec 13, 2023Svolvaer, Lofoten Islands, Norway

Housed in the Arctic Circle, Norway"s Lofoten Islands are a crossroads of traditional life and modern industry. One of two towns in Lofoten, Svolvaer boasts a long history as a fishing village. Before it became a town of its own, it was part of the town of Vågan, where people have lived for over 1,000 years. Beyond fishing, it also serves as a sanctuary for travelers looking for a peaceful getaway, with as many as 200,000 visitors in a single year. The traditional rorbu houses, built on poles over water, add a distinctive layer of charm to the town. These cabins were once made for traveling fishermen and have now been refurbished to meet contemporary tastes.Desktop Version

Apr 9, 2023Happy Easter!

Humans have been decorating eggs for Easter for centuries, but decorated ostrich eggs have been found from as far back as 60,000 years ago, long before the Christian festival began. The Easter egg has long been a symbol of fertility and rebirth, but exactly why people started decorating them is unclear. One theory is that, because animal products were not eaten during the religious Lenten season, people would hard-boil the eggs and decorate them with dye and wax, until they could be eaten at Easter. A more opulent type of decorated egg, Fabergé eggs, were famously created as bejeweled Easter gifts to the Russian imperial family. Our homepage image shows eggs from Lithuania, where people use traditional methods to paint patterns with wax using sharp objects or etch patterns into dyed eggs.Desktop Version

Nov 14, 2019The perfect canvas for an ancient text

Since 2009, the city of Durham has served as a grand stage for the biennial Lumiere Durham festival. During four days in November, works of "son et lumière"—a French phrase that means "sound and light"—provide spectators with new ways of viewing public spaces and buildings. Artists from around the world design large-scale light shows paired with narratives and sound effects. It"s become the UK"s largest light festival, and Lumiere Durham"s 10th anniversary, which begins today, promises to attract more than 200,000 people to enjoy the illuminated artworks along cobbled streets.Desktop Version

Dec 17, 2021Bournemouth beach huts

Today we"re taking our bucket and spade to the seaside resort of Bournemouth on the south coast of England. OK, it might be a bit chilly to build sandcastles this time of year, but the festive glow of these cozy beach huts will warm us up as we enjoy a stroll along the seafront for the town"s annual Christmas Tree Wonderland—a trail featuring more than 100 glittering trees and illuminations. The huts in our photo have been decked out for the holidays, providing visitors with the perfect scene for a seasonal selfie—or should that be elfie?Desktop Version

May 28, 2021Freeloaders of the avian world

Ever felt like some folks are just born jerks? Birds can relate. Take for example the uninvited speckly-white visitor to this robin"s nest: That smaller egg belongs to a baby cowbird whose mother sneakily laid it among the blue robin eggs when no one was looking. Once the baby birds all hatch, the cowbird will grow much faster and larger than its robin "siblings," soon becoming an only chick by muscling them right out of the nest. And if mama robin ejects the cowbird egg before it hatches, the cowbird mom may take notice and chuck the remaining robin eggs from the nest out of spite.Desktop Version

Sep 18, 2019Celebrating Chile’s Independence Day

That’s the Villarrica volcano providing fireworks for our observance of Chile’s Independence Day celebrations—called Fiestas Patrias—taking place September 18 and 19. The second-most active volcano in South America, Villarrica is known to the indigenous Mapuche people as Rucapillán (Devil’s House). The eruption shown in this photo, which was taken on September 2, 2018, alarmed nearby residents, but it wasn’t nearly as destructive as other relatively recent eruptions, like one in 2015 that prompted authorities to evacuate thousands of people.Desktop Version

Oct 9, 2021Birds of a feather

For World Migratory Bird Day, we"ve journeyed down to Bosque del Apache National Wildlife Refuge in southern New Mexico to join a group of sandhill cranes and their mallard duck friends as they feed in shallow water. Each year beginning in late October, this 57,000-acre refuge becomes the winter home to tens of thousands of migratory birds including sandhill cranes and various species of geese and ducks who travel from as far away as Alaska and Siberia to hunker down in warmer climes. They stay until late February when they begin their journey back north to their summer homes.Desktop Version

May 29, 2021A path into history

When it comes to tourist destinations, the Wuhou Temple in the city of Chengdu, China, must be among the world"s oldest. It"s been attracting visitors for nearly 1,800 years and remains one of the most popular attractions in all of China. Located in Sichuan province, this temple complex was constructed to honor two principal members of the Shu Han state (221-263) of China"s early Three Kingdoms period. And although the founder of Shu Han, Liu Bei, is honored with his own temple and shrine here, the real headliner is one of China"s most important historical figures, Zhuge Liang, who is remembered as a great wit, scholar, astronomer, statesman, and military strategist. In fact, the name Wuhou itself derives from the Chinese title "Marquis of Wu," which was an honorary title given to Zhuge Liang.Desktop Version

Dec 19, 2022Northern cardinal in winterberry bush

This scarlet winterberry shrub is the perfect hiding place for the northern cardinal. What better spot for singing in the winter holidays? Winterberry is a deciduous holly that"s native to North America and can be a modest shrub or a tree reaching up to 15 feet. The yellow and green flower clusters that bloom in spring give way to bright red berries in winter.Desktop Version

Dec 24, 2022Christmas Eve

This isolated cove on "the Last Frontier" is the least likely place you"d expect to find a Christmas tree decorated from head to toe with lights aglow. Amalga Harbor lies about 15 miles north of Juneau (one of the few coastal state capitals in the US) and shows that the public expression of Christmas cheer knows few limitations–and may include use of a small barge. This photograph was taken from nearby Ernest Gruening State Historical Park, which was named for the former governor of the Alaska Territory. Gruening led the territory from 1939 to 1953 before becoming one of the state"s first US senators when Alaska became a state in 1959. After his political career ended, he and his wife lived in a cabin that was preserved as part of this historic site.Desktop Version

Sep 18, 2023Fall Astronomy Week

The Milky Way has billions of stars; among them, our own sun finds its place. The galaxy"s name is derived from the radiant, pale appearance of the band of stars and gas clouds that graces Earth"s sky. Methodical observations of the night sky started with early civilizations but astronomy, the oldest natural science, remains a source of fascination today. It"s what brings stargazers to Portugal"s Southwest Alentejo and Vicentine Coast Natural Park, a site free from heavy light pollution. Now"s a good time to seek out your own celestial spectacle, as it is Astronomy Week and the main event, Saturday"s Fall Astronomy Day, this year coincides with the autumnal equinox.Desktop Version

Feb 21, 2020Carnival comes to Olinda

It"s the first official day of Carnival in Olinda and the streets in the historic part of town will be alive with revelers who come out to see dozens of giant puppets parade through the town. The larger-than-life "bonecos de Olinda" kick off the festivities each year and have been part of the celebrations here for over a century. They can be up to 20 feet tall and weigh around 45 pounds each. But Carnival in Olinda is not only about these incredible puppets. Like other Carnival celebrations in Brazil, Olinda"s features music, dancing, costumes, and fun.Desktop Version

Oct 17, 2022Long-eared owl in the Czech Republic

Whooo is that up in that tree? Why, that"s just a typical long-eared owl, sometimes called the lesser horned owl or cat owl. It"s one of the most numerous owl species in the world with an estimated population between 2 million and 5.5 million long-eared owls widely distributed across the Northern Hemisphere. Our featured friend today was found in the Czech Republic, but they"ll adapt to several kinds of habitats.Desktop Version

May 25, 2023Saksun, Faroe Islands, Denmark

Nestled in a picturesque valley next to a lagoon flanked by mountains, Saksun is a small, remote village famous for its stunning vistas. It is situated on the coast of Streymoy in the remote Faroe Islands, which sit about halfway between Iceland and Scotland in the North Atlantic. Home to these iconic houses with turf roofs and a tiny population—estimates vary between 8 and 30—it is said that there are more waterfalls in Saksun, than houses.Desktop Version

Feb 2, 2023Groundhog 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

Nov 19, 2021Zion National Park, Utah

Today, we"re celebrating the 102nd anniversary of southwest Utah"s Zion National Park with a visit to its Subway slot canyon. Zion is defined by its breathtakingly steep red cliffs, its maze of sandstone canyons, and its waterfalls with colorful hanging gardens. Visitors here can trek for miles, ducking into crevices and resting in canyons once occupied by the Ancestral Puebloans.Desktop Version

Jul 27, 2021Maybe we should be looking up

When it first flicked on the projector lights in 1930, the Adler Planetarium in Chicago was the only one in the Western Hemisphere, and it featured an innovative new lens imported from Germany. But the American public"s fascination with stars and distant worlds, it turned out, was skyrocketing. By 1934, the Adler had welcomed over a million visitors.Desktop Version

Nov 2, 2021Day of the Dead

If you"ve ever been in Mexico during Day of the Dead festivities, then you"ve no doubt come across the beautiful orange flowers you see here. Marigolds are one of the main symbols of this festive, two-day celebration. The flowers are native to North America, and were deemed sacred by the Aztecs, who likened their bright colors to the sun. According to legend, those colors and the flowers" sweet aroma have the power to lure the souls of the dead back to this world from beyond.Desktop Version

Dec 12, 2023Poinsettia Day

During the holiday season, poinsettias brighten up homes in suitably festive coloring, serving as symbols of goodwill. December 12 marks National Poinsettia Day, a special occasion to celebrate this holiday favorite. The plant was introduced to the US by Joel Roberts Poinsett, a botanist and former minister to Mexico who died on this day in 1851. Poinsettias can be found growing in the wild from Mexico to Guatemala. The ancestors of the modern, commercially available version have been traced to the Mexican state of Guerrero. The crimson-leaved plant was used by the Aztecs as a red dye and as a fever-reducing medicine.Desktop Version

Oct 27, 2022Bridge of Sighs in Venice, Italy

Beneath Venice"s Ponte dei Sospiri (Bridge of Sighs) is a popular place to kiss your beloved as a gondolier guides you through the city"s canals. But the sighs that the name refers to aren"t from staring into your darling"s eyes. The enclosed bridge, completed in 1600, connects the Prigioni Nuove (New Prison) to the interrogation rooms in the Doge"s Palace, and it is said that a prisoner"s last look at beautiful Venice would be from that bridge. And that"s reason enough to sigh indeed.Desktop Version

Jul 12, 2023Nakupenda Beach Nature Reserve, Zanzibar, Tanzania

Off the west coast of Zanzibar, the Nakupenda Beach Nature Reserve sits on a small, sandy island. Surrounded by the Indian Ocean, this sand bar is a popular destination with tourists looking to soak up the sun"s rays on its white sands. Plentiful marine life here creates a vibrant underwater world that is perfect for snorkeling. The islands of Tanzania are home to an array of wildlife like the Pemba scops owl and the African fish eagle. To the north of Nakupenda, there is a giant tortoise sanctuary on Changuu Island, while their sea turtle cousins swim in the surrounding waters.Desktop Version

Aug 16, 2021Let s ride! It s Roller Coaster Day

Whether screaming with delight and waving their hands or closing their eyes and praying for it to be over, these riders are on the downslope of one of Europe"s biggest and fastest hypercoasters (that"s a roller coaster over 200 feet tall). Spain"s PortAventura Park is home to seven coasters, more than enough to get the adrenaline pumping. The Shambhala coaster, seen here, reaches 256 feet above the ground and has a max speed of 83 miles per hour. If that"s too tame, the park"s Red Force roller coaster climbs to 367 feet and reaches 112 miles per hour. Hang on!Desktop Version

Sep 20, 2021Birds of a feather flocking together

In the fall and spring, thousands of people come to the marshlands of the Wadden Sea, between Denmark and Germany, to watch huge flocks of starlings take flight at sunset. The birds synchronize their movements in a flocking behavior called murmuration. They swoop, shift, and turn as one, creating incredible shapes in the sky.Desktop Version
