An impactful day
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
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
Bridge of Sighs in Venice, Italy
Bridge 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
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
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
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
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
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
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
Svolvaer, Lofoten Islands, Norway
Svolvaer, 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
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
On the wings of the Wright brothers
On the wings of the Wright brothers
For National Aviation Day, we’re highlighting a rare view from inside a wind tunnel at NASA’s Langley Research Center in Virginia. The plane is a replica of the historic craft that was invented, designed, and flown by the Wright brothers in what’s generally acknowledged to be the first powered airplane flight–an event that took place on Dec. 17, 1903, near Kitty Hawk, North Carolina. On that day, both Wilbur and Orville Wright took turns flying their aircraft, dubbed the Wright Flyer, cementing their place in aviation history. Their original plane lives at the Smithsonian’s National Air and Space Museum in Washington, DC, where it inspires generations of pilots and innovators to come.Desktop Version
Fall Astronomy Week
Fall 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
Great hornbill, Thailand
Great hornbill, Thailand
The great hornbill is a remarkable bird found in the tropical forests of Southeast Asia. Despite weighing as much as 9 pounds and growing up to 4 feet long, it is an agile flyer capable of maneuvering through dense forests. Alongside its striking black and yellow plumage, the great hornbill has a unique helmet-like casque on its bill, which amplifies its calls. The bird primarily feeds on fruit but also eats small mammals, reptiles, and insects. While incubating her eggs, the female great hornbill seals herself inside a tree cavity, leaving a small opening through which the male inserts food. This magnificent bird holds cultural and spiritual significance in many Southeast Asian cultures as a sacred animal and the subject of festivals.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
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
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
Stepping into autumn
Stepping into autumn
Look closely and you"ll see a snake slithering down the steps of the Temple of Kukulcan (aka El Castillo or The Castle), in Chichen Itza, Mexico. Not a real snake, it"s an image created by natural light and shadows only during the spring and fall equinoxes. The equinox (which means equal night in Latin) is either of the two times each year—like today, the first day of fall—when the Earth"s orbit and position cause the sun to pass directly over the equator, creating equal amounts of daylight and darkness. According to Mayan legend, on both equinoxes this pyramid is visited by Kukulcan, the feathered serpent god. Thousands of spectators gather to watch and celebrate as seven triangles of light slide down the pyramid, illustrating Kukulcan"s descent.Desktop Version
Happy Boxing Day!
Happy Boxing Day!
December 26 isn"t just a day for Santa to put his feet up and sleep off all those mince pies. In many British Commonwealth countries, today is known as Boxing Day, a holiday that originated in the United Kingdom. There are a few conflicting theories about its origins, but it"s generally accepted that the name derives from the giving of "boxes" to lower classes on the day after Christmas. One thing is certain—it has nothing to do with pugilism, although it has primarily become a day dedicated to sporting events and shopping, much like the Friday after Thanksgiving in the US.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
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
A Latino art exhibition in Denver
A Latino art exhibition in Denver
National Hispanic Heritage Month begins today in the United States. To explore the breadth of the Latino experience in the US, one might start with art—especially work from contemporary artists such as Gabriel Dawe, whose work is shown here. This is "no. 36" from Dawe’s Plexus series, a collection of art installations constructed from embroidery thread. The Plexus series is named for the networks of blood vessels and nerves that run through the human body. Dawe writes that his work–centered on textiles–seeks to examine gender and identity in his native Mexico and to subvert notions of masculinity and machismo. "Plexus no. 36," was on display at the Denver Art Museum in 2017.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
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
