Jul 30, 2018Children at play for International Day of Friendship

Does this photo of kids at play in Kolkata, India, prompt memories of fun times you had as a child, when the world didn’t extend much further than you and your friends? If so, you’re in the right frame of mind to celebrate International Day of Friendship, or just Friendship Day. The idea began in a bid of crass commercialism: The holiday was invented and marketed by the founder of Hallmark Cards. But the public saw through that and it didn’t take. Decades later, a peace-promoting group called the World Friendship Crusade relaunched Friendship Day in Paraguay as a way to foster peace. It’s been gaining traction ever since.Desktop Version

Jan 9, 2024Balloon Ascension Day

Up, up, and away! Today is Balloon Ascension Day, celebrating the anniversary of the first manned balloon flight in North America. French aeronaut Jean-Pierre Blanchard"s flight took him from Philadelphia to Deptford, New Jersey, back in 1793. Interest in ballooning took off from there and today, hot air balloon festivals take place across the country, including Albuquerque, where today"s sunrise image was taken. Every year, hundreds of thousands of people attend the nine-day Albuquerque International Balloon Fiesta—the largest hot air balloon festival in the world—to see skilled pilots expertly maneuver their baskets through balloon-filled skies.Desktop Version

Jul 10, 2019Put your helmet on, we’re going for a hike

You’ll need to wear a safety helmet before stepping onto the cliff-hanging path that passes above the Gorge of Gaitanes in Spain"s Málaga province. Look around, but don’t forget to look down from the glass-floor observation platform. This is your opportunity to fully appreciate the 325-foot drop below and consider what life must be like as a mountain goat. The renovated path is far less dangerous than the original, which for many years had no guard rails. Made for workers back in 1905, the first walkway provided access between El Chorro and Gaitanejo hydroelectric power plants. After King Alfonso XIII visited in 1921, the walkway was given its nickname, El Caminito del Rey (The King’s Little Pathway). But after years of use and lack of upkeep, the nickname was updated to ‘The world’s most dangerous walkway.’Desktop Version

Sep 13, 2018They’re grrrape!

When you hear wine experts talk of ‘Burgundies,’ they are referring to wines made in this French region. The most common varieties are Pinot noir and Chardonnay, but farmers here grow many different types of grapes. September and early October is grape harvest time in France, so the usually quiet rows of grape vines we see in this photo are probably very busy with workers gathering the fruit to be crushed and fermented. We’re thinking about putting together a bread and cheese plate right now…Desktop Version

Nov 19, 2022Zion National Park turns 103

Our photo brings us to a 16-mile stretch of the Virgin River where it cuts a spectacular thousand-foot-deep gorge through the upper reaches of Utah"s Zion Canyon. Flowing through Zion National Park (which turns 103 today!), the Virgin River is home to unique plants and animals that aren"t found anywhere else, due to the unique intersection of biomes found where the Colorado Plateau, Great Basin, and Mojave Desert all meet. Without the water of the Virgin River system, creatures like the woundfin minnow, one of rarest species on the planet, couldn"t exist.Desktop Version

Sep 17, 2018Gateway to America

We’re here at Ellis Island in honor of Constitution Day and Citizenship Day, an annual observance that recognizes both the adoption of the US Constitution and those who have become US citizens. For more than 60 years, Ellis Island served as a gateway for millions of immigrants arriving in the United States—and it’s easy to imagine them gazing at the Statue of Liberty from this very window, while contemplating their new lives in the United States. These days, Citizenship Day is a popular time for federal courts to hold naturalization ceremonies, when new American citizens are sworn in. These free, often celebratory events are open to the public, and are often attended by students learning about citizenship.Desktop Version

Nov 15, 2024Yi Peng lantern festival, Chiang Mai, Thailand

As twilight descends today, Chiang Mai, Thailand"s second-largest city, will come alive with thousands of glowing lanterns for Yi Peng. Held on the full moon of the second month of the Lanna lunar calendar, this celebration is about letting go of negativity and embracing new beginnings. The highlight of the festival is the release of "khom loi" or "khom loy"—floating paper lanterns—into the night sky, which becomes a sea of warm, golden lights. People often write their hopes and dreams on the lanterns. They gather around temples and palaces to send their wishes skyward, hoping for good fortune in the year to come.Desktop Version

Apr 23, 2021A house of grand scale(s)

We"re looking at the rooftop of Casa Batlló, a six-story building in the center of Barcelona topped with colorful "scales." What brings us here? Well, here in the Catalonia region of Spain, and in several other locales from England to Ethiopia, it"s the feast of Saint George. You know George (or Jordi, as the Catalans call him): He"s the knight who, legend holds, saved a much-loved princess by defeating a fierce dragon. It"s said the tower jutting from the casa"s tiled roof represents George"s lance thrust into the monster"s scaly back.Desktop Version

Jul 25, 2023Laguna de Torrevieja, Spain

When we encounter bodies of water in nature, we might expect hues of blue, from the pale cyan shade of lagoons to the navy blue of deep lakes. But pink water—where on Earth could that be found? At (deep breath) El Parque Natural de Las Lagunas de La Mata y Torrevieja in Alicante, Spain. Here, there are two lakes: one green and one pink, and it is the latter that you see on our homepage. The highly saline water, dotted with clusters of salt crystals, is the perfect environment for microscopic algae, which are rich in carotenes. This results in the rosy tinge that protects the algae from solar radiation. And the pink is just getting started, as the algae are eaten by tiny crustaceans, which turn pink and are then eaten by flamingos, which acquire the rosy hue as well.Desktop Version

Oct 15, 2020A star is borne by seaweed

With a little "kelp," this starfish is enjoying a change from its typical view of craggy tidal beds. Both passenger and vehicle in this photo, taken off California"s coast, play important roles in their ecosystems.Desktop Version

Oct 16, 2020It s harvest time on World Food Day

This tractor is transporting trailers full of one of the world"s most versatile veggies: cabbage. A stalwart in Slavic recipes, a key ingredient in Korean kimchi, and essential to that sauerkraut on your ballpark dog, it"s the perfect cosmopolitan crop to represent World Food Day.Desktop Version

Jan 18, 2022Winnie-the-Pooh Day

Today we"re in England"s Ashdown Forest, a tranquil patch of woods 30 miles south of London in East Sussex. We"ve wandered here because this is the enchanted forest that inspired author A.A. Milne"s depiction of Winnie-the-Pooh"s neighborhood, the Hundred Acre Wood. It"s our way of celebrating Winnie-the-Pooh Day, observed each year by the Pooh faithful on January 18, Milne"s birthday. The author, along with help from illustrator E.H. Shepard, introduced the world to Pooh and his many forest friends with the beloved "Winnie-the-Pooh" books, first published in 1926.Desktop Version

Jun 13, 2021Bear watching in the Finnish forest

If you go out to the woods today in parts of Finland, you might get a big surprise. That"s because about 2,000 brown bears can be found freely roaming the taiga—or boreal forest—which covers most of the country, making this rugged wilderness in northern Europe the perfect place to see these majestic animals in their natural habitat. And bear watching is a popular pastime in Finland. The bear-watching season begins in April—when the first bears emerge from hibernation in a white blanket of snow—and lasts until fall. Summer nights are the best time to spot the bears, even under the golden glow of the midnight sun for those who venture north of the Arctic Circle. Many observe the creatures from the safety of a "hide," a purpose-built wooden cabin offering visitors a close-up view of a real teddy bear"s picnic.Desktop Version

Jan 2, 2024Prayer flags in Phobjikha Valley, Bhutan

This kaleidoscopic column is made up of prayer flags, blowing in the breeze in the Phobjikha Valley, Bhutan. Prayer flags come in five repeating colors representing different elements in nature, blue for the sky, white for air, red for fire, green for water, and yellow for earth. The fluttering fabrics, inscribed with spiritual scripts, are usually raised during times of prosperity, such as on Bhutan"s Nyinlong, their traditional day of solstice, which takes place today. As the flags fade over time, adherents believe this signifies that the prayers have been heard and are being carried away by the wind, infusing the surrounding area with positivity and spirituality.Desktop Version

Aug 29, 2020Big wheels on a big mountain

Today we"re high in the French Pyrenees at the Col d"Aubisque, a beautiful mountain pass topping out at 5,607 feet above sea level. The Col d"Aubisque is one of the legendary climbs of the Tour de France, which starts today in Nice. The grueling bicycle race lasts 23 days (21 days of racing), with riders clocking around 2,200 miles overall, and this mountain pass is often one of its most challenging stages. The road up the pass has grades in either direction that can tilt past 10%. This epic mountain stage was first added to the 1910 race and it"s since appeared in more than half the annual Tours, though not this year as it happens.Desktop Version

Jun 3, 2021Get on your bike and ride

In honor of the UN"s World Bicycle Day, we"re at Triglav National Park in Slovenia, with a bird"s-eye view of riders crossing this dubious-looking wooden suspension bridge over the blue glacial water of the river called Soča. Protecting some of the most magnificent mountain landscapes of the Julian Alps, Triglav is the country"s only national park, but it"s a stunner. Running along Slovenia"s northwestern border with Italy, Triglav was first protected as a "conservation park" in 1924, then made a national park in 1981. The park gets its name from the mountain at its heart, Triglav, long considered a symbol of Slovenia and of Slovene identity.Desktop Version

Dec 27, 2021Snow buntings take flight

These snowflakes have feathers! The birds you see in this wintry image are snow buntings, sometimes referred to as "snowflakes" because of the distinct white in their wings. These medium-sized Arctic specialists love the cold and travel farther north than other passerine birds. Only ravens can be found north of snow buntings.Desktop Version

Dec 24, 2021Smoking nights in Austria

Behold the lovely Tannenbaum ("fir tree" for you non-German speakers). Here in Tyrol, Austria, Christmas Eve marks the first of three Rauchnächte, or "smoking nights." A long-standing Tyrolean tradition, people in this Alpine region burn frankincense and herbs in homes, barns, and stables to avert bad fortune. The custom is then repeated on the other two "smoking nights," New Year"s Eve and the night before Epiphany.Desktop Version

May 8, 2023Arches National Park, Utah

This stunning structure is Delicate Arch, the most famous of 2,000 stone arches scattered around Arches National Park in Utah. It is made up of Entrada Sandstone, the grains of which once formed a massive desert. They were cemented together by minerals, forming sandstone riddled with tiny holes. Over millennia, the rain seeped in and slowly dissolved the rock from the inside, forming these eye-catching sculptures. Most of the arches in the national park are formed from Entrada Sandstone and were once buried by other rock layers. They won"t last forever, but over time, new shapes will emerge from the layers of rock below to replace them. Every year, close to 1.4 million people visit the park to see Delicate Arch and this slowly shifting landscape for themselves.Desktop Version

Jun 11, 2023Goliath heron in Kruger National Park, South Africa

You are looking at the largest living heron in the world, the goliath heron, waiting for prey to swim by in Kruger National Park, South Africa. This wading bird is often referred to as the giant heron due to its enormous size—reaching as tall as 5 feet in height with up to a 7-foot wingspan. The goliath heron is a solitary creature, known for its slow, hunting-style movements and lives around lakes, swamps, and wetlands. They forage in deep waters and feast on large fish, like mullet and tilapia, as well as small animals including frogs, snakes, and lizards. They are often found in sub-Saharan Africa, with smaller numbers in western and southern regions of Asia.Desktop Version

Feb 11, 2020Celebrating women in science

For the International Day of Women and Girls in Science, we"re visiting the Great Barrier Reef with oceanographer Dr. Sylvia Earle. This photo is from the 2014 documentary film "Mission Blue," which follows Earle, a legendary marine biologist, environmentalist, and National Geographic Explorer-in-Residence. The film focuses on Earle"s campaign to create a global network of protected marine sanctuaries. Sometimes called Her Deepness, Earle has made immense contributions to science over her career. From leading groundbreaking research in deep ocean science to becoming the first female chief scientist at the National Oceanic and Atmospheric Administration, Earle is recognized as one of the world"s preeminent oceanographers.Desktop Version

Nov 7, 2022Lunar eclipse

If you missed the first full lunar eclipse of the year back in May, you"ll get another chance tonight as the second blood moon (as lunar eclipses are often called) of 2022 takes to the sky over the Pacific region. Tonight"s display can be seen from Asia, Australia, North America, and parts of northern Europe and South America. If you"re lucky enough to find yourself under a clear sky, the view might look something like this image, taken over Mount Crested Butte, Colorado, during the lunar eclipse of September 27, 2015.Desktop Version

Dec 31, 2022New Year s Eve in Sydney, Australia

With New Year"s Eve landing in midsummer, many Aussies choose to usher in the new year with a boat trip around beautiful Sydney Harbour to take in the annual fireworks display. With the Sydney Harbour Bridge and world-famous Sydney Opera House as a dramatic backdrop, the first fireworks show will fire off this year at 9 PM local time, followed by a second show at midnight. Australia is one of the first nations to greet the new year, and more than 1.5 million people are typically in attendance for this spectacular celebration in Sydney.Desktop Version

Aug 14, 2021When Death Valley blew its top

Deep below Death Valley"s charred surface, blazing hot magma once gushed up through a geologic fault until it hit groundwater. The magma quickly turned the water to steam, and like a defective subterranean pressure cooker, the Earth"s crust blew its top in a ferocious explosion. The hydrovolcanic eruption sent up a mushroom cloud of steam and spewed burnt volcanic cinders for miles. It also left the giant crater seen in this photo and 12 smaller ones spread across the surface.Desktop Version
