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
Gifford Pinchot National Forest
Gifford Pinchot National Forest
Today we"re paying a visit to an "elder statesman" of the United States" national forests. Seen in today"s photo is Panther Creek Falls at Gifford Pinchot National Forest in Washington state. Officially, the forest was named in 1949 in honor of Pinchot, the first head of the US Forest Service. Located between Mount St. Helens to the west and Mount Adams to the east, the land was set aside as a place worth preserving as far back as 1897. But people had been living in the forest for more than 6,000 years. Archaeologists continue to make discoveries within the dense forest that teach us about the past lives of Native Americans.Desktop Version

World Population Day
World Population Day
On July 11, 1987, the world is thought to have welcomed its 5-billionth person. Thirty-six years later, our population has reached 8 billion and is still rising. World Population Day, established by the UN, is a day to reflect on how much life Earth can sustain, and how our lives impact our environment.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
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
Computer Science Education Week
Computer 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
It s aboat time for the Barcolana
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
National Cherry Blossom Festival
National Cherry Blossom Festival
Want to experience spring in all its glory? If you head to the National Cherry Blossom Festival in Washington, DC, you"re in for a blooming good time! The festival commemorates the 3,000 cherry trees given to the city by the mayor of Tokyo in 1912. Twelve varieties were originally gifted but these days most of the trees are either Yoshino or Kwanzan cherries. Those circling the Tidal Basin, the location of the Jefferson Memorial featured in today"s image, are Yoshino trees. The event has evolved to become a four-week celebration that attracts over 1.5 million people every year. The highlights of the festival include a lively parade filled with large, colorful helium balloons, stunning floats, and marching bands from all over the country.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
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
An icy extravaganza
An icy extravaganza
We’re just outside Brainerd, Minnesota, for the Ice Fishing Extravaganza on Gull Lake. Each year in late January, more than 10,000 people will come out to catch as many fish as they can—mostly walleye and northern pike, but all fish species are eligible. The contest is organized and run by volunteers exclusively, and 100 percent of the proceeds—around $150,000—goes to local charities.Desktop Version
Mount Segla, Senja Island, Norway
Mount Segla, Senja Island, Norway
A beautiful island popularly known as "Norway in miniature," Senja"s diverse landscape boasts mountainous terrain as well as lush greenery. At 600 square miles, it is Norway"s second-largest island, connected to the mainland by the Gisund Bridge. The most notable spot on Senja is pictured today, Mount Segla, a magnificent peak that is visited frequently in summer, with a trail starting in Fjordgård, a fishing village in the north of Senja. It"s a tough hike to the top, more than 2,000 feet above sea level. Other tourist attractions include Ånderdalen National Park and Tranøya, an island off the south coast of Senja known for its tranquility.Desktop Version
Carnival of Venice
Carnival of Venice
Don your tricorn hat and gilded disguise, it"s time to visit the Carnival of Venice. This centuries-old festival combines revelry with anonymity, thanks to the masks traditionally worn by attendees, from the classic square-jawed Bauta mask to the Colombina eye mask, with roots in Italian theater. Costumed rowers take part in a parade of traditional boats on Venice"s famous Grand Canal while thousands of people wearing elaborate costumes enjoy the carnival atmosphere. Parades, parties, concerts, and performances will fill the streets until festivities end on Shrove Tuesday, which falls on February 13 this year. Visitors might pass by the Santa Maria della Salute, seen toward the back of today"s image, a baroque basilica dedicated to the Virgin Mary, who is considered to be the protector of the city.Desktop Version
Antarctica Day
Antarctica Day
The windiest, coldest, and driest continent on Earth—Antarctica—was officially discovered in 1820. In the following decades, several countries organized expeditions to reach and explore the Antarctic ice sheets. The southernmost continent had no indigenous population and various nations claimed ownership. But in 1959, 12 countries signed the Antarctic Treaty, banning military activities and setting Antarctica aside for scientific research. Today, we celebrate the anniversary of this treaty, which now has 56 parties.Desktop Version

Dark Sky Week
Dark Sky Week
During International Dark Sky Week, we"re counting ourselves lucky to have this spectacular nighttime view, considering the astonishing fact that 83% of the global population lives under a light-polluted sky. Unneeded artificial light is classified as a pollutant and has been proven to have harmful side effects. Not only does it waste money and energy, it also disrupts plants and animals, is believed to impact the climate, and blocks our view of the universe.Desktop Version
Pont Rouge
Pont Rouge
When the Pont Rouge (Red Bridge) of Sainte-Agathe-de-Lotbinière was built over the Palmer River in 1928, covered bridges were already commonplace here in Quebec. Simple designs imported from the United States allowed relatively untrained workers to quickly construct crossings like this. "Ponts rouges" (often called this whether or not they were painted red) popped up wherever rural French Canadians required a convenient river crossing—as many as 1,500 were built between the late 1800s and the 1950s. Today fewer than 100 still stand, and some—like this one—are protected by local and provincial agencies for historic preservation.Desktop Version
The artists come to Venice
The artists come to Venice
Our photo today shows a small part of artist Claudia Fontes’ sculpture called "El Problema del Caballo" (The Horse Problem). The Argentinian artist exhibited the large installation work with smashed pieces of stone surrounding the larger-than-life white horse, as if it had crashed into the exhibition space. The installation was shown in 2017 at the Venice Biennale, where artists from around the globe bring their work to show off at this every-other-year arts and culture festival in the Italian city of Venice. The Biennale is just starting up again this month, and many of the programs and exhibits will be going on through the summer and into fall.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
The lemurs of Madagascar
The lemurs of Madagascar
What better place to ring in World Lemur Day than Madagascar? The island, about the size of Texas off the coast of southeastern Africa, is the native home to lemurs. Today you"ll find over 100 species and subspecies of the critters here. Most are small, with a pointed nose, large eyes, and a tail. They mainly live in trees and can be highly social, like the ring-tailed lemurs on our homepage, or live a solo existence like the elusive aye-aye. Lemurs have opposable thumbs and five fingers with fingernails on each hand, characteristics that help secure their spot as members of the primate order of mammals. About 65 million years ago, scientists believe, lemurs drifted on rafts of vegetation from the African continent to the shores of Madagascar. Safe from competition and most predators, lemurs evolved into many highly specialized varieties and now can be found in almost all habitats on the island.Desktop Version
Capitol Reef National Park, Utah
Capitol Reef National Park, Utah
Behold the rugged grandeur of Utah"s red rock country. This hidden gem of the American Southwest is Capitol Reef National Park, a tapestry of towering cliffs, twisting canyons, colorful sandstone buttes, and sweeping desert landscapes. Less popular than Zion and Bryce Canyon, the park offers a pleasantly uncrowded experience for visitors keen to enjoy this spectacular landscape. It is also home to a wide variety of plants and animals, including the elusive desert bighorn sheep and more than 230 bird species. But its crown jewel is the nearly 100-mile long Waterpocket Fold, a 7,000-foot-high step in the rock layers, officially known as a monocline. This massive wrinkle on the surface of the planet was formed around 50 to 70 million years ago.Desktop Version
World Meteorological Day
World Meteorological Day
They might look like spaceships from a retro sci-fi movie, but these strange shapes hovering above the mountains in Patagonia are of earthly origin. These are lenticular clouds, named after their lens-like shape. They form near hills and mountains where moist air is pushed up and over the peaks, cooling as it rises and condensing into water droplets. As wind blows over the mountains it can create a series of waves in the air, and these unusual clouds form in the crest of those waves.Desktop Version
Breckenridge, Colorado
Breckenridge, Colorado
Gold mining put this Rocky Mountain town on the map in the 1860s, but today the real gold is the powdery snow that falls liberally on the slopes that surround the town. Breckenridge is one of Colorado"s premier ski and snowboard destinations. The resort has 35 lifts servicing five peaks and 2,900 acres of terrain. The visitors—who also arrive in the summer to fish, cycle, and paddle—easily outnumber the 5,000 residents of this quaint village. The gold mines have long shut down, apart from hosting visits from tourists. The enduring value of Breckenridge is its natural beauty.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
