Celebrating 78 years of Everglades National Park
Celebrating 78 years of Everglades National Park
On Florida"s southern tip lies one of the United States" most unusual landscapes. The Everglades is not a typical swamp or river. It is a slow, shallow sheet of water that drifts south across flat grasslands toward Florida Bay, linking forests, marshes, mangroves, and coastal prairies. This subtropical wilderness supports hundreds of species, including alligators, manatees, and the endangered Florida panther. On December 6, 1947, the United States established the Everglades National Park, protecting over 1.5 million acres and shifting conservation toward preserving entire ecosystems rather than isolated landmarks.Desktop Version
Black History Month
Black History Month
Some months arrive quietly, but February knocks on the door, flips on the spotlight, and says, "Let"s give credit where it"s long overdue." That"s the spirit of Black History Month—a time to celebrate African American achievements, confront hard truths, and honor those who shaped the country. It began in 1926 when historian Carter G. Woodson launched Negro History Week. The week grew, spread through schools and communities, and by 1976 it officially expanded into a month.Desktop Version

Horsetail Fall in Yosemite National Park, California
Today we celebrate the birthday of Ansel Adams, a photographer whose vision helped shape the world"s perception of Yosemite National Park. Yosemite is renowned for its granite walls, dramatic waterfalls, and striking light, all of which have inspired generations of artists. One of its most intriguing sights is the Firefall, a term that refers to two distinct events in the park"s history. For decades, visitors gathered at Glacier Point to watch an artificial Firefall, in which embers were pushed off the cliff in a glowing stream of fire.Desktop Version

Purple crocus flowers, Seven Rila Lakes, Bulgaria
As winter"s grip on the Rila Mountains of southwestern Bulgaria begins to loosen, crocuses push through the thinning snow, signaling the arrival of spring in the country"s highest mountain range. These early bloomers use stored nutrients to quickly grow in cold conditions, completing much of their life cycle before taller plants emerge. Their clustered blossoms unfurl over alpine meadows in sweeping purple ribbons, creating a striking contrast with bright snowfields and crisp morning light.Desktop Version

It"s a quirky tradition that turns a small rodent into a celebrity meteorologist.Desktop Version
International Sloth Day
International Sloth Day
How good would it feel if you could just hang out and do absolutely nothing all day? That"s exactly what sloths do, and today, we celebrate them. International Sloth Day honors these unhurried creatures and reminds us that life doesn"t always need to be rushed. Sloths are tree-dwelling mammals native to Central and South America. Their deliberate movements conserve energy, avoid predators, and even allow algae to grow on their fur, creating green camouflage among the canopy. Hoffmann"s two-toed sloth, pictured here, is a prime example of the slow-paced lifestyle typical of all sloths. It spends most of its time in the trees, occasionally descending to the ground to move to a new one.Desktop Version

Starling murmuration over the ruins of Brightons West Pier, England
When a bird is called a starling, you"d expect it to be a bit of a show-off. True to its name, this little creature knows how to steal the spotlight. From shimmering feathers that glint green and purple in the sun, to its ability to mimic sounds, the starling is the headline act. Originally native to Europe and Asia, the common starling has spread across the globe. In the 19th century, a group of them were introduced to New York"s Central Park by an enthusiast of birds mentioned in Shakespeare"s plays.Desktop Version

Emerald Bay and Fannette Island, Lake Tahoe, California
Emerald Bay and Fannette Island, Lake Tahoe, California
You know a place holds stories when geologists, filmmakers, and local folklore all claim it for different reasons. Lake Tahoe, straddling the border between California and Nevada, fits that bill perfectly. Formed during the Ice Age, the lake was shaped by faulting and glacial carving that created its deep basin. It is now one of the deepest freshwater lakes in the United States. For generations, the Washoe people lived around these clear waters, fishing and gathering seasonally. Centuries later, miners arrived, steamboats crossed the water, and Tahoe shifted from a resource hub to a year-round retreat.Desktop Version
The Brocken, Harz National Park, Germany
The Brocken, Harz National Park, Germany
Imagine reaching the Brocken in Harz National Park, Germany, as clouds slide across the ridge. With the sun behind you, mist ahead—then a giant, haloed shadow forms. Ever wondered why climbers once feared this sight? The phenomenon, called the Brocken spectre, is an eerie natural optical effect that occurs when sunlight projects a person"s shadow onto cloud or fog. Rising about 1,141 metres, the Brocken is the highest peak in northern Germany and has long inspired folklore, including tales of witches gathering here during Walpurgis Night.Desktop Version
Plate ice along Lake Superior, Grand Marais, Minnesota
Plate ice along Lake Superior, Grand Marais, Minnesota
When winter tightens its grip on Lake Superior in Minnesota, the shoreline transforms into a landscape of tilted, glass-like shards known as plate ice. Thin sheets fracture under shifting temperatures, then drift and stack as the wind presses them toward land. The result is a field of translucent blues and silvers, catching the light at sharp angles and making the water"s edge appear sculpted rather than frozen.Desktop Version
Male hooded merganser, Oregon
Male hooded merganser, Oregon
Each fall, Oregon"s quiet waterways become seasonal waypoints for hooded mergansers—small diving ducks native to North America. They are agile divers, plunging beneath the surface to catch fish and other prey. Males, known as drakes, stand out with their fan-shaped white crests, dark heads, and chestnut-brown sides, while females, called hens, are brownish gray with smaller crests. Oregon"s lakes and wetlands provide sheltered feeding grounds as these birds migrate or winter across the continent.Desktop Version

Today, people in more than 180 countries participate.Desktop Version
Red deer stag in De Hoge Veluwe National Park, Netherlands
Red deer stag in De Hoge Veluwe National Park, Netherlands
Picture 21 square miles of open land, wildlife on the move, and a stag flaunting its crown of antlers. In 1909, husband and wife Anton Kröller and Helene Kröller-Müller began building a private estate in Gelderland, Netherlands—what we now know as De Hoge Veluwe National Park. Their vision? To merge art and nature. They brought it to life by placing artwork within the landscape, like "Three Upright Motives" by English sculptor Henry Moore in the Pampelse Zand and the President Steyn stone bench by Belgian architect Henry van de Velde, among others.Desktop Version
Old Rock Day
Old Rock Day
Today is a day that puts time into perspective. Old Rock Day highlights the vast geological processes that have shaped our world since its earliest eras. In Arches National Park, Utah, Turret Arch—seen through North Window—offers a striking reminder: landscapes can take hundreds of millions of years to assemble. The Entrada Sandstone that forms these arches began as shifting dunes and shallow seas long before erosion carved today"s shapes. Even so, these formations are relatively young. Most rocks on Earth disappear over time because plate tectonics, erosion, and volcanism continually recycle the crust. Only the planet"s ancient continental shields preserve truly old material. Canada"s Acasta Gneiss, about 4 billion years old, is the oldest known rock still rooted where it formed.Desktop Version

Martimoaapa Mire Reserve, Finland
Martimoaapa Mire Reserve, Finland
Today, we step into the Martimoaapa Mire Reserve in Finland, where wide, cold-climate wetlands and peatlands stretch across a landscape shaped over thousands of years. This reserve is more than just mires—it carries layers of history. During Finland"s Prohibition era (1919–1932), smugglers hauled sacks of liquor from Sweden across these bogs, following a "spirits" route that passed through Martimoaapa. Parts of that path can still be traced today. Imagine trekking with a heavy pack over soggy ground—would you have made it?Desktop Version

Boxing Day
Boxing Day
The best thing about Boxing Day is that it doesn"t ask much of you. No big countdown. No dramatic unwrapping. No last-minute dashes for batteries. It"s a rare holiday that says, "Sit down, finish your leftovers, and take a moment." Celebrated on December 26 in the United Kingdom and some Commonwealth countries, it"s a national cool-down after Christmas has done all the heavy lifting. The term goes back to Victorian Britain, when households prepared Christmas boxes for workers and tradespeople—tokens of thanks that ranged from coins to essentials. Churches joined in by opening alms boxes and distributing donations.Desktop Version
