Kirkilai lakes, Biržai Regional Park, Lithuania
Kirkilai lakes, Biržai Regional Park, Lithuania
Curving above the treetops of Biržai Regional Park in northern Lithuania, this unusual structure allows a bird"s-eye view of a unique landscape. Built in 2015, the Kirkilai Observation Tower"s shape is said to resemble a sinking boat, appropriate in an area dotted with water-filled sink holes. About 30 of these small lakes can be seen from the top of the tower, nearly 100 feet in the air. These lakes can be up to 36 feet deep and are just some of the thousands of sinkholes identified in the park. Water-soluble rocks like gypsum lie under the soil in this area, and over time they gradually erode, forming caves, which then collapse. In some cases, they fill with water, creating this mesmerizing landscape. The interconnected lakes mirror the surrounding greenery, creating a scenic haven for nature enthusiasts.Desktop Version
Summer solstice
Summer solstice
What more atmospheric place to celebrate today"s summer solstice than ancient Glastonbury in Somerset, England? Spend the longest day of the year exploring the town, which is swaddled in myth and history. Pagans and Christians alike have worshipped here through the ages, and both groups still do today. Glastonbury Tor is the striking hill on the horizon, and the lonely tower is the last vestige of the 14th-century church of St Michael, which was built to replace a wooden church toppled by an earthquake in 1275.Desktop Version
World Lion Day
World Lion Day
Lions are known as "the king of the jungle," but on World Lion Day, let"s set the record straight: Lions don"t live in the jungle. Lions lounge in lordly leisure and hunt with ferocious focus on grasslands and plains. When they"re not hunting, these majestic creatures nap, wrestle, and groom each other. But in an instant, they"re chasing down a hapless gazelle or a hippopotamus that"s wandered too far from the safety of its river. Like the opening song of "The Lion King" movie says, it"s the circle of life. World Lion Day is our opportunity to (ahem) lionize these regal beasts and raise awareness of threats to their well-being like poaching, habitat destruction, and other human-lion conflicts.Desktop Version
Giant kelp in the Channel Islands National Marine Sanctuary
Giant kelp in the Channel Islands National Marine Sanctuary
All along the Pacific Coast of North America, giant stands of kelp up to 100 feet high, like this one in California"s Channel Islands, provide habitat for a vast number of fish, invertebrates, and sea mammals. Giant kelp, technically a type of brown algae, is the largest of all seaweed and one of the fastest-growing of any organism—as much as 2 feet per day! The gas-filled pods you see in this image help the kelp float. Like the trees in the Amazon, the kelp forests of our oceans are key to the health of marine life.Desktop Version
Constitution Day and Citizenship Day
Constitution Day and Citizenship Day
Constitution Day and Citizenship Day is a single celebration that commemorates the formation and signing of the US Constitution while also recognizing both naturalized citizens and those born in the US. It"s a day to learn about these subjects, as well as a day many people become naturalized citizens in group ceremonies. (On average, about 700,000 people become US citizens every year.) To celebrate, we"re looking at an unusual close-up of the Statue of Liberty, a welcoming sight to immigrants and a symbol of freedom since 1886. The statue"s tablet has the date of the signing of the Declaration of Independence (July 4, 1776) inscribed in Roman numerals: JULY IV MDCCLXXVI.Desktop Version
Natural Bridges State Beach in Santa Cruz, California
Natural Bridges State Beach in Santa Cruz, California
California brown pelicans, cormorants, and gulls enjoy jostling for position on top of this stunning rock formation in Natural Bridges State Beach in Santa Cruz. It is the sole surviving natural "bridge" in this state park. Once three bridges stood side-by-side here, carved by waves into cliffs that jutted out into the Pacific. This one stood in the middle, but the outermost bridge collapsed in 1905 and the innermost one disappeared in 1980.Desktop Version
World Philosophy Day
World Philosophy Day
On World Philosophy Day, we"re in Athens, the capital of Greece, the birthplace of Western philosophy and democracy. The iconic Acropolis, the ancient citadel that towers over Athens, and its most famous monument, the Parthenon, remind us of the brilliant minds of Socrates, Plato, and Aristotle. Ancient Greek philosophy focused on critical thinking and questioning and started a revolution of rationale that is still shaping our society today. UNESCO recognizes the profound impact philosophy has on human thought, cultures, and individuals on World Philosophy Day. Take time today to discover the depths of the "love of wisdom"!Desktop Version
Veterans Day
Veterans Day
For Veterans Day today, we"re featuring a moment captured back in 2016 of US sailors on the amphibious assault ship USS Iwo Jima. It was Veterans Week in New York City, and the ship was sailing across the Hudson River on its way to participate in the events. Every year on November 11 we celebrate Veterans Day and honor all service members living or dead, including these sailors. There are currently around 19 million living veterans and 1.3 million active service members in the US.Desktop Version
Happy Halloween!
Happy Halloween!
These mask-like monsters of the Minster wish you a hearty "Happy Halloween"! That"s York Minster, by the way, the towering medieval cathedral in the heart of York, England, decorated with these impish figures meant to scare off evil spirits. Just don"t call them gargoyles (for that title to apply, they"d need waterspouts)! Statues like these fellas bear an even more Halloween-appropriate name: grotesques.Desktop Version
Bohemian Switzerland
Bohemian Switzerland
Today we rhapsodize about the beautiful region called Bohemian Switzerland, but we"re hundreds of miles from Switzerland. The name for the area originated with Swiss painters visiting the Kingdom of Bohemia, now the western half of the Czech Republic. They were reminded of their homeland by this region"s dramatic sandstone formations. Turns out the acclaimed artist named Mother Nature finds inspiration here, too, turning the Bohemian Switzerland’s pockets of thick forest into a canvas of warm oranges and yellows every autumn.Desktop Version
National Moon Day
National Moon Day
Bigger and brighter than anything else you can see from Earth in the night sky, the moon has inspired our calendar, our songs, our art, our stories, and our dreams. Today, on National Moon Day, we remember one dream that came true on this date in 1969: the day humans first set foot on the lunar surface. So far, it"s the only place beyond our planet that humans have visited.Desktop Version
It s National Hispanic Heritage Month
It s National Hispanic Heritage Month
National Hispanic Heritage Month takes us to the Texas border town of El Paso, where artist Jesus "CIMI" Alvarado is pictured applying the final touches to the mural he calls "Fronterizos" (Border People). It was commissioned by the El Paso Museum of Art for one of its outside walls. Alvarado began his painting career as a graffiti artist, tagging the walls of the city"s historic Segundo Barrio, and today his work can be found throughout the city. This mural depicts a local musician, Johnny Barragan, with an unnamed woman, and is described as an ode to a hometown hero of El Paso.Desktop Version
The Guggenheim turns 60
The Guggenheim turns 60
Today"s image shows the Guggenheim on the day before its grand opening, 60 years ago today. Since then, it"s become an iconic building in the New York cityscape. Housed in a white spiral building that emerges from Fifth Avenue, the museum started with several private collections, including that of founder Solomon R. Guggenheim. The collection has grown over the decades to contain some of the world’s most notable examples of impressionist, post-impressionist, early modern, and contemporary art.Desktop Version
Dog days of summer
Dog days of summer
Other than our pet dogs, no other canine species has succeeded more at living among humans than the fox. This is despite the fact that people have hunted foxes for sport and for their highly coveted fur, and generally regarded them as pests and nemeses. No matter how we feel about them, foxes seem to have earned our respect. Of all the animals that are arguably clever and crafty, the word we use is "outfoxed," not "outcrowed," or "outbeared," or "outraccooned."Desktop Version
Zelenci Nature Reserve, Slovenia
Zelenci Nature Reserve, Slovenia
Experience nature"s palette at its colorful best at Zelenci Springs, where Italy, Austria, and Slovenia meet, and multiple springs combine to form this aquamarine lake. Here in Slovenia’s Triglav National Park, these crystal-clear waters are the source of the Sava Dolinka, which runs into the country’s longest river, the Sava. Peer closely at the lakebed and you will see tiny springs bubbling up beneath the water"s surface. These spring waters never freeze as underground water temperatures stay around 41 degrees Fahrenheit, enough to keep flowing through harsh winters in this alpine region.Desktop Version
Pi Day
Pi Day
Today we"re observing Pi Day with a bird"s-eye view of the hedge maze at Cyherbia Botanical Park near Ayia Napa in Cyprus. It"s the day we celebrate the mathematical constant π. Today"s date, March 14, was chosen because when expressed numerically, it matches the first three digits of pi: 3.14. You remember pi from geometry class—it"s the ratio of the distance around a circle to the distance across it. Pi is used to compute a circle"s area and circumference. The circular labyrinth at the Cyherbia Botanical Park brings the ratio to life and is a must-visit for people who love to solve puzzles. If you"re ready for a challenge, give it a go.Desktop Version
Albuquerque International Balloon Fiesta
Albuquerque International Balloon Fiesta
October means pumpkin fields, Halloween, leaf-peeping, and the World Series. But in Albuquerque, New Mexico, the beginning of October means a skyful of hot air balloons. The 50th Albuquerque International Balloon Fiesta is the largest gathering of balloonists in the world, with more than 500 hot air balloons going aloft this week. The now nine-day event got its start by launching 13 balloons from a shopping mall parking lot in 1972 to celebrate the birthday of a local radio station. It has easily become the biggest event of the year in Albuquerque, whose entire populace can view balloons in flight simply by stepping outside their homes and looking up.Desktop Version
Mada in Saleh, Saudi Arabia
Mada in Saleh, Saudi Arabia
About 2,000 years ago, Mada"in Saleh, or Hegra as the Romans called it, was a thriving city of the Nabataean Kingdom, and a center for the trade of spices, incense, and myrrh, a valuable tree resin used to make perfume and medicine. The Nabataeans were Arab people whose precise origins are unknown. They lived in northern Arabia and the Southern Levant. Mada"in Saleh was their second-largest and southernmost city after Petra, their capital city to the north. About halfway between Petra and Mecca, Mada"in Saleh served primarily as a trading crossroads and was instrumental in establishing the Nabataeans as prosperous middlemen to the rest of the ancient world.Desktop Version
Ponta Delgada
Ponta Delgada
Today we"re taking a trip to the verdant cliffs at the edge of Madeira, the principal island of the Portuguese archipelago that"s also called Madeira, roughly 320 miles west of Morocco in the North Atlantic. These terraced hillsides are just outside the village of Ponta Delgada, on the north coast of the island. Originally uninhabited, Madeira and the other islands in this chain were settled by the Portuguese in the early 1400s and became a main stopover for European explorers during the so-called Age of Discovery.Desktop Version

World Children s Day
World Children s Day
For World Children"s Day, we"re featuring an aerial view of a larger-than-life painting on the summit of the Moléson in the Swiss Prealps. The 16,000-square-foot fresco is titled "Un Nouveau Souffle" (A New Breath) and depicts a child blowing clouds toward the horizon. It was created by French-Swiss artist Saype—real name Guillaume Legros—who is known for his grassy graffiti around the world. The eco-friendly artist uses biodegradable paints made from natural pigments such as coal and chalk, so by the time you read this, his land art will have already disappeared into the soil.Desktop Version
Noctilucent clouds
Noctilucent clouds
It"s around this time of year when some lucky people get to witness these rare, wondrous clouds. Known as noctilucent, or "night-shining," clouds, they"re the highest clouds in our sky and are only visible during summer. They"re made up of icy dust glowing at the edge of space, roughly 50 miles above the planet"s surface. The trick to seeing them is to gaze up into the sky at twilight, when sunlight is not reaching the Earth"s surface, but is still shining through the high-altitude noctilucent clouds. These clouds occur more often at high latitudes but have been seen lower than 50° north and south.Desktop Version
Procida, Italy
Procida, Italy
Procida is a charming Italian island in the Gulf of Naples, boasting colorful buildings, picturesque streets, and stunning sea views. The island has a rich history, having been settled by the Greeks, Romans, and other civilizations over the centuries, but is less well-known than its larger neighbours, Capri and Ischia. Its oldest fishing village, Marina Corricella, features pastel-colored buildings and narrow streets and is a great place to enjoy fresh seafood and soak up the atmosphere. From there, you can climb up to the fortified medieval village of Terra Murata, built on the island"s highest point, which offers panoramic views over the entire Gulf of Naples.Desktop Version
Galeries Lafayette, Paris
Galeries Lafayette, Paris
Surely one of the grandest stores found in any city is the Galeries Lafayette in Paris. It"s not just a place to shop but a destination as popular as any in the City of Light. At a time when department stores are fading and the entire retail industry is shifting, the Galeries Lafayette holds fast. It has survived financial crises, wars, and now the internet, remaining a celebrated part of life in Paris. Like Macy"s or Rockefeller Center in New York, the Galeries Lafayette is synonymous with the holidays. A giant fir is decorated every holiday season under the store"s signature stained glass dome—a ritual of Christmas cheer that Parisians have embraced for generations.Desktop Version
International Day of the Tropics
International Day of the Tropics
Only in the tropics do forests grow in salt water. Take this forest of mangrove trees in Phang Nga Bay in southern Thailand, one of the largest and best-preserved mangrove forests in the country. Adapted to thrive in coastal marshes and swamps, mangroves can filter salt water and withstand strong coastal storms. Virtually all mangrove forests and all species of mangrove grow only in the tropical regions of the world. They are protectors of the coastlines, acting as a buffer against storms and floods.Desktop Version
