King of the dinosaurs
King of the dinosaurs
No other dinosaur has quite the notoriety of the Tyrannosaurus rex. The species gained widespread popularity in 1905, when a New York Times article hailed it as "the king of all kings in the domain of animal life," and the "absolute warlord of the earth." The so-called "tyrant lizard" has been a star ever since, regularly appearing in film, TV, literature, and—for some of us—nightmares.Desktop Version
Reflecting on one of the world s strangest rivers
Reflecting on one of the world s strangest rivers
If you like your landscapes on the surreal side, then this weird and wonderful river in the Andalusia region of southwestern Spain should be to your liking. The Rio Tinto (Red River) gets its name from the reddish hue of its water, caused by high levels of iron and sulfur, which make it very acidic. This unusual chemical makeup may or may not be a result of the area"s long history of mining, which dates back at least 5,000 years. Ancient residents like the Tartessians and Romans dug here for copper, silver, and gold, as well as the mineral pyrite, commonly referred to as "fool"s gold." Legend has it that the Rio Tinto was the site of the fabled mines of King Solomon.Desktop Version
Not your average sandcastle
Not your average sandcastle
Memorial Day is the unofficial start of summer, so of course we’re heading to the beach—the city beaches of Valencia, Spain. Valencia is famous for its beautiful, golden sand beaches, where people build incredible sand sculptures, like this one on Malvarrosa Beach. An elaborate sand sculpture can take over a week and multiple people to build. In fact, the world’s tallest sandcastle reached over 50 feet into the sky. But if you’ve got the time, sand, and water, you too can build a cool sandcastle.Desktop Version
What’s blooming in New Zealand?
What’s blooming in New Zealand?
Lupines—or "lupins" as they"re generally called here in New Zealand—usually hit peak bloom around mid-to-late November in the Mackenzie region of the South Island. This image shows the burst of color along the shores of Lake Tekapo, famed for its annual lupin blooms. The colorful carpets of purples, pinks, blues, and whites along waterways and roads look stunning, drawing tourists to the area, and locals appreciate the economic benefits that come with these visitors. But lupins hail from North America, and in New Zealand, they"re considered invasive species that crowd out native flora, ruining the habitat for birds like the wrybill, banded dotterel, and other species that live along the waterside.Desktop Version
1, 1, 2, 3: It s Fibonacci Day!
1, 1, 2, 3: It s Fibonacci Day!
Today"s date, November 23, can be represented as 11/23, or 1, 1, 2, 3—the beginning of the Fibonacci sequence of numbers. Likewise, as the leaves on the Queen Victoria agave in today"s image spiral out from the center, they also express the Fibonacci sequence. This unique sequence of numbers was introduced to Europe in 1202 by the Italian mathematician Leonardo of Pisa (posthumously named Fibonacci) in his revolutionary work, the "Liber Abaci." The book begins by describing the Hindu-Arabic numeral system or "Modus Indorum’—0 1 2 3 4 5 6 7 8 9—and shows how its application could simplify trade and make calculations faster and easier (most of Europe at this time used Roman numerals).Desktop Version
Reflecting on fall
Reflecting on fall
Some of the best things about fall in many parts of the country are the amazing colorful displays across the landscape. While the trees here in Beaver Lake Nature Center, near Syracuse, New York, are already bare, the autumn ferns cast a radiant reflection on the water. This 661-acre natural area contains a 200-acre glacial lake that draws migrating Canada geese to its shores. Visitors may also see more than 200 other species of birds and over 800 varieties of plants. The nature center is a destination for cross-country skiing in the winter, while the summer months are popular for kayaking and canoeing.Desktop Version
A center of antiquity on the Mediterranean
A center of antiquity on the Mediterranean
This bird"s-eye view lets us take in the charms of Ortygia, a small island just offshore from Syracuse, on Sicily"s east coast. Ortygia is considered Syracuse"s "old town" and the historical heart of the city. Two bridges cross the narrow channel that separates Ortygia from Syracuse. Ancient Greeks first colonized this island in the 8th century BCE, and the town is brimming with 2,700 years of history. Walk Ortygia"s web of narrow streets and you"ll see Greek and Roman ruins, medieval Norman buildings, and examples of Baroque architecture as well.Desktop Version

That s quite a schnoz, baby tapir
For World Tapir Day, we"re bringing you nose-to-nose with a baby South American tapir. The creamy stripes and dashes on its coat help keep this endangered calf camouflaged under the filtered light of the Amazon tree canopy. It may look small now, but mature tapirs are the largest native mammals in South America. About that nose: Tapirs use their prehensile nose trunk to grab plants and berries. And if they submerge under the surface of the water, some even use it as a snorkel.Desktop Version

Gauchos showcase Argentina’s independent spirit
Gauchos are a national symbol here in Argentina, which celebrates its independence today, 202 years after it broke free from Spanish rule. These gauchos are showcasing their skills in the town of San Antonio de Areco, home to an annual gaucho festival that draws people from all over. The gauchos gather to share traditional food, folklore, and competition. Since the 18th century, gauchos have been known as skilled, brave horsemen and their exploits are celebrated in South American literature and popular culture.Desktop Version
The ‘Night of Nights’
The ‘Night of Nights’
This is the cypress tunnel at Point Reyes National Seashore, a nature preserve on the California coast north of San Francisco. The tunnel leads to KPH, a ship-to-shore radio station that once broadcast messages to marine craft in the Pacific. KPH stopped operations in 1997, as more sophisticated radio equipment and satellite communications made radio stations like it obsolete. Now it’s one of the unusual features of Point Reyes, open to visitors interested in a glimpse of the past.Desktop Version

It’s National Dolphin Day!
We’re celebrating National Dolphin Day by heading to the waters offshore from Kaikoura, New Zealand, where a pod of dusky dolphins is surfacing along South Island’s Pacific Coast. The ‘dusky’ descriptor comes from the dark gray, sometimes black coloring on the marine mammal’s back. Dusky dolphins are found only in the Southern Hemisphere.Desktop Version
The dancing trees of Sumba Island
The dancing trees of Sumba Island
On the northern coast of Indonesia"s Sumba Island, a stand of mangrove trees appears to dip and sway to summon another dreamy sunrise. Walakiri Beach is gently sloped, so it"s easy for a visitor to walk out into the knee-deep water to examine the extraordinary transitional zone of a mangrove ecosystem. Mangroves thrive here at the boundary between land and sea, growing in coastal salt water and low-oxygen conditions where other trees would quickly die. Their complex root systems filter out the salt and form a strong natural defense against storm surges, rising sea levels, and coastal erosion. Mangroves also create aquatic nursery habitats that support a highly diverse range of juvenile fish and crustaceans.Desktop Version

This far-out image of the Sahara Desert was photographed from space via the Sally Ride EarthKAM, a camera aboard the International Space Station. The EarthKAM is programmed remotely by middle school students as part of an educational program established by Sally Ride, the first American woman to travel to space. Ride’s first trip to space was in 1983. On May 26, her birthday, we remember her legacy.Desktop Version
Moody skies over Valletta
Moody skies over Valletta
We approach from the Mediterranean to arrive at a 2018 European Capital of Culture: Valletta, Malta. This celebration of city-specific culture began in 1985, and since 2010 two cities have shared the title each year (Valletta shares the 2018 honors with Leeuwarden, in the Netherlands). Valletta, the southernmost capital of Europe, has a remarkable range of architectural styles throughout the city, from 16th-century churches to the ultra-modern Parliament House. Aside from its rich homegrown culture, Valletta reflects a variety of outside influences, including several jazz clubs and a Baroque music festival.Desktop Version
Winter in the Wild West
Winter in the Wild West
When considering the dramatically eroded canyons of southwestern Utah, snow may not be the first thing that comes to mind. But far-flung Bryce Canyon National Park gets plenty of the white stuff, owing to its elevation of 8,000-plus feet at the massive amphitheater"s rim. The cold not only provides scenic snowy views and great cross-country skiing, it"s responsible for the striking red-rock pinnacles—known as hoodoos—that make the park so unique.Desktop Version
Ringing in the new year at Teotihuacan
Ringing in the new year at Teotihuacan
If the Aztecs had hot air balloons, they may well have greeted the new year like this—floating above the massive Pyramid of the Sun at sunrise today, the first day of the year according to the Aztec calendar. Also known as Yancuic Xihuitl, the Aztec New Year is still celebrated by some Indigenous Nahua communities here in central Mexico with songs, dances, and the flames of "ocote" (pitch pine) candles. Dancers wear colorful traditional costumes topped by quetzal feather headdresses, and celebrants greet the new year by making loud noises with seashells, just as Aztecs did centuries ago. It"s one of the many expressions of pre-Columbian tradition that managed to survive the Spanish conquest and modern erosion of Indigenous customs.Desktop Version

New York State isn’t all skyscrapers and teeming crowds. The Empire State is home to a diverse geography, including some wild places that were around back on July 26, 1788, when New York officially joined the Union. In honor of New York’s statehood day, we’re at Letchworth State Park, a wilderness near Rochester that follows the Genesee River some 17 miles through a deep gorge that’s known as the "Grand Canyon of the East."Desktop Version

A lush, green escape
With the tourist season winding down and the rainy season still forthcoming, September is an ideal time to visit Bali. If you’re lucky enough to go, plan a day trip to the Tegallalang farming terraces in Ubud, where visitors can capture gorgeous photos of the landscape and get an unforgettable glimpse into Balinese culture. The island of Bali has a rich tradition of agriculture, with an especially unique method of water management for rice farming. The irrigation system here, known as Subak, is recognized by UNESCO for its cultural significance. Water flows through temples and into the rice paddies, carved into the hillsides like steps. It"s a practice that dates back thousands of years, based on the Balinese philosophical principle of Tri Hita Karana, which refers to a relationship between humans, the Earth, and the gods.Desktop Version

An emerald isle of the Emerald Isle
An emerald isle of the Emerald Isle
If you were to find yourself wandering across the tiny island of Inisheer on March 17, you"d almost certainly hear someone greet you with a hearty "Lá fhéile Pádraig sona dhuit!" That"s because nearly all the island"s 260 residents would want to wish you a happy Saint Patrick"s Day in their native Irish tongue. The smallest of the three Aran Islands that are strung across the mouth of Galway Bay in western Ireland, Inisheer has been inhabited from prehistory—artifacts from as early as the Bronze Age have been found scattered around its 1,400 acres. The tiny drystone wall subdivisions of the fields are a result of a long tradition of splitting family farms between all the children. After a few generations, farms were reduced to the garden-size patches you can see here.Desktop Version
