Camel thorn trees, Namib-Naukluft Park, Namibia
At first glance, it looks like a surreal art installation: dark trees frozen on a clay pan, backed by sand dunes and a glowing sky. But this scene from Deadvlei, in Namibia"s Namib-Naukluft Park, is entirely natural. The name "Deadvlei" means "dead marsh"—a remnant of the wetland that once filled this basin.Desktop Version

Devils Tower National Monument, Wyoming
Devils Tower National Monument, Wyoming
Somewhere in the wide prairies of northeastern Wyoming stands Devils Tower, a stone formation that rises from the open plains. Once called Bear Lodge, the butte gained its current name during an 1875 expedition led by Colonel Richard Irving Dodge, possibly after an interpreter mistranslated a Native phrase as "Bad God"s Tower." The missing apostrophe in its official title follows standard geographic naming conventions—hence, the signs read "Devils Tower." In 1906, President Theodore Roosevelt proclaimed it the nation"s first national monument; a milestone whose anniversary falls today.Desktop Version

Little Pigeon River, Great Smoky Mountains, Tennessee
Little Pigeon River, Great Smoky Mountains, Tennessee
You"ll hear it before you see it. The steady ripple, the splash of trout, the distant laughter of hikers. That"s the Little Pigeon River, threading its way through Great Smoky Mountains National Park in Tennessee. Long before tourists tubed it and fly fishers angled in it, this river was how people stayed afloat. The Cherokee tribe fished in it. Settlers built grist mills along it. Towns like Gatlinburg and Pigeon Forge grew up next to it. Even the river"s name is a nod to the past—the passenger pigeon, once common in the area, vanished by the early 1900s.Desktop Version

Thousand Islands region, St. Lawrence River, US-Canada border
When you hear "Thousand Islands," you might think of a jar of salad dressing, but the namesake of that creamy condiment is one of North America"s most enchanting regions. The Thousand Islands form an archipelago in the St. Lawrence River, spanning the state of New York and the province of Ontario. It is made up of more than 1,800 islands. Some of these islands have fairytale castles; others are barely big enough for a hammock. There"s also Just Room Enough Island, which lives up to its name with a single house and a lone tree.Desktop Version

Northern gannets, Shetland Islands, Scotland
Graceful, powerful, and impossible to miss—the northern gannet is the largest seabird on the waters of the North Atlantic. It spends most of its time gliding over open seas and returning to land only to breed. These seabirds, known for their vast and noisy breeding colonies, called gannetries, nest on steep cliffs, remote rocky islands, and sea stacks that rise from the ocean.Desktop Version
Old City of Dubrovnik in Dalmatia, Croatia
Old City of Dubrovnik in Dalmatia, Croatia
There is something mesmerizing about cities that wear their history on their sleeves—and Dubrovnik, Croatia, is one of them. Once known as the independent Republic of Ragusa, this city was a major maritime power and trading hub from the 14th to the 19th century. Situated in southern Dalmatia along the Adriatic Sea, its success was built on diplomacy and seafaring. The Walls of Dubrovnik, built between the 13th and 17th centuries, stretch for over 1.2 miles, with towers, forts, and bastions still standing strong. The current layout of the walls follows a city plan from 1292, when Dubrovnik was rebuilt after a fire under Venetian rule.Desktop Version
Perseid meteor shower over Nevada
Perseid meteor shower over Nevada
Get ready for one of the most dazzling celestial displays of the year—the Perseid meteor shower. Active from mid-July through late August, this year it reaches its spectacular peak on the night of August 12 and into the early hours of August 13. The Perseids light up the skies when Earth passes through a trail of icy and rocky debris left behind by Comet Swift–Tuttle, which last passed close to our planet in 1992. These meteors are called the Perseids because they appear to streak from the direction of the constellation Perseus.Desktop Version
Squirrel Appreciation Day
Squirrel Appreciation Day
Today"s image shows a Eurasian red squirrel perched in the snow, displaying the winter fur and tufted ears that make this species so striking. Native to forests across Europe and parts of Asia, red squirrels rely on seeds, nuts, and fungi, stashing food in scattered caches and building nests high in hollow trees to survive the colder months.Desktop Version
Spotted eagle rays in the Galápagos Islands
Spotted eagle rays in the Galápagos Islands
It"s a bird, it"s a plane, it"s … a fish! Gliding through the ocean with flapping fins and polka-dot flair, the spotted eagle ray refuses to blend in. It doesn"t crawl along the seabed like its stingray cousins—it flies underwater. The species gets its name from—you guessed it—its protruding snout, which resembles an eagle"s beak, and its distinctive spotted back, which is unique to each individual, much like fingerprints. Their wing-like pectoral fins can span up to 10 feet. Near the base of the long tail are venomous spines, in case a predator gets too close. These rays aren"t aggressive, but they"re not defenseless either.Desktop Version
A Eurasian red squirrel in Switzerland
A Eurasian red squirrel in Switzerland
Quick, clever, and always on the move—meet the Eurasian red squirrel, a leafy treetop resident found across much of Europe and Asia. While it prefers the shelter of forests, this agile creature easily adapts to gardens and parks. It builds its nest, called a drey, high in the fork of a tree using twigs to form a domed structure about 10 to 12 inches wide. The female featured here is gathering moss—one of several soft materials, along with bark, leaves, and grass, that line the nest and turn it into a snug, well-insulated retreat. These rodents may also take over tree hollows or abandoned woodpecker holes when available.Desktop Version
Tide pools in La Jolla, California
Tide pools in La Jolla, California
Not every science lesson requires a classroom. In La Jolla, California, tide pools teach you about ocean life—right at your feet. Along the rocky shoreline of this San Diego coastal neighborhood, tide pools form during low tide as seawater gets trapped in natural depressions. These shallow pools form naturally along La Jolla"s rocky shorelines, especially near Windansea Beach, Shell Beach, South Casa Beach, and Hospital Point. The water that remains trapped in sandstone and reef depressions creates habitats for everything from sea hares to brittle stars. Over time, the tide pools are created through the process of erosion—waves hit the sandstone and limestone coastlines until they carve out pockets that hold water. Twice a day, as the tide moves in and out, these spaces flood and drain, challenging the survival skills of everything inside. Winter months, when tides are lowest during daylight hours, are ideal for observing them.Desktop Version

Audubon Christmas Bird Count
Audubon Christmas Bird Count
Each December, thousands swap wrapping paper for binoculars and step outside for a different kind of holiday tradition: the Audubon Christmas Bird Count. Instead of hunting for bargains, they hunt for birds—with pencils, rather than pellets. Started in 1900 by ornithologist Frank M. Chapman, the count offered a peaceful alternative to the Christmas "side hunts," where people competed to shoot the most animals. Chapman had a better idea: count them instead. Over a century later, that simple shift has grown into the world"s longest-running citizen-science project.Desktop Version

Shark Awareness Day
Shark Awareness Day
Sharks have been around for over 400 million years—outlasting dinosaurs, surviving ice ages, and weathering mass extinctions. They are symbols of ocean health, which is why Shark Awareness Day draws attention to these apex predators that help maintain balance in marine ecosystems. Protecting sharks means preserving the health of entire ocean environments—and ultimately, securing a sustainable future for all life. With many shark species facing the threat of extinction, this day is all about appreciating their ancient legacy and learning how we can help keep them off the endangered list.Desktop Version
Ancient til trees in Fanal Forest, Madeira, Portugal
Ancient til trees in Fanal Forest, Madeira, Portugal
The Portuguese island of Madeira—about 600 miles southwest of mainland Portugal—hides a forest unlike any other. On its northern slopes lies Fanal Forest, where veils of mist drift through centuries-old til trees. These are part of the Laurissilva of Madeira—an outstanding relict of a once widespread laurel forest type. Laurissilva is the largest surviving area of its kind, with about 90% considered primary forest. Home to a unique array of plants and animals, including endemic species such as the Madeiran long-toed pigeon, it remains a living museum of natural history.Desktop Version

National Lighthouse Day
National Lighthouse Day
Before GPS told ships where to go, lighthouses lit the way—each with its own flash pattern so sailors could figure out where they were, even in total darkness. It"s National Lighthouse Day, a perfect excuse to give these coastal workhorses some credit. In 1789, Congress passed a law to make sure all lighthouses were taken care of by the federal government. Whether you"re a history buff, coastal explorer, or just into old engineering, today is a great day to learn more about lighthouses or visit one with your friends and family.Desktop Version
