World Population Day
World Population Day
We are living in a full house, and it is getting fuller. With 8.2 billion people and counting, World Population Day highlights how that growth affects cities, food, and the future. First observed in 1989, the day focuses on how unchecked population growth affects sustainability. The event was inspired by Five Billion Day in 1987, which marked the approximate date when the global population hit that milestone. As cities expand, green spaces shrink, and agriculture competes for limited land and water resources. But there is a way forward—investing in education, improving access to healthcare, and building smarter cities can balance growth with sustainability.Desktop Version
Maritime forest in Cumberland Island National Seashore, Georgia
Maritime forest in Cumberland Island National Seashore, Georgia
Before you hit the beach, you"ll hear it—the rustle of leaves in salty air, the creak of twisted trunks, the hush of an old world. Welcome to the maritime forest of Cumberland Island National Seashore on the southernmost stretch of Georgia"s Atlantic coast. Salt spray, sandy soil, hurricanes? The trees here stand their ground. Live oaks bend but don"t break. Saw palmettos crowd the ground like leafy bodyguards, while Spanish moss hangs from branches like nature"s fringe. This maritime forest is one of the best remaining examples of this rare habitat in the United States. Thanks to its national seashore status, the island has been spared from the concrete creep seen on other coastlines.Desktop Version

Vatican City with St. Peters Basilica
Vatican City with St. Peters Basilica
In the middle of Rome, Italy, lies an entire country of its own: Vatican City. At just 121 acres, it"s the smallest independent nation in the world, yet its reach spans centuries and continents. Home to the pope and the spiritual center of the Roman Catholic Church, this walled enclave is a blend of art, history, and devotion. At its core stands St. Peter"s Basilica. Seen in the distance in today"s image, this Renaissance masterpiece is built over what is believed to be the tomb of St. Peter, the first bishop of Rome. With its soaring dome dominating the skyline, the basilica is one of the largest churches in the world. Just beyond the basilica lies St. Peter"s Square, where thousands gather for papal blessings. The Vatican Museums and the Sistine Chapel, which houses Michelangelo"s famed ceiling, are other must-sees. Despite its size, Vatican City has its own postal service, telephone system, and banking system.Desktop Version

Patriot Day
Patriot Day
September 11, 2001, began like any other day—until history changed in an instant. Nearly 3,000 innocent lives were lost in the terrorist attacks on the World Trade Center, the Pentagon, and aboard United Airlines Flight 93. Today, on Patriot Day, we honor the fallen and the countless acts of courage that emerged in the face of tragedy, from firefighters and first responders to ordinary citizens who became heroes. At 8:46 AM Eastern Time—the moment the first plane struck the North Tower—Americans observe a moment of silence. Permanent memorials now stand at each of the three sites. Visiting one or volunteering in your community is a meaningful way to participate in the National Day of Service and honor those who continue to serve.Desktop Version
Splendid leaf frog
Splendid leaf frog
Don"t let the name fool you—this frog isn"t just leafing around. The splendid leaf frog (aka splendid tree frog) is a rainforest resident with a flair for the dramatic: neon legs, sticky feet, and a disappearing act. One minute it"s a humble green leaf, the next it"s a flash of color mid-leap, startling predators. This frog lives high in the canopies of Central and South America, especially in Costa Rica, Panama, and parts of Ecuador and Colombia. It spends its days snoozing on leaves and its nights foraging for insects. With vertical pupils and a golden glow, oversized eyes help this frog spot prey in the dark. Thanks to sticky toe pads and strong limbs, it can cling to branches and leaves like a pro, even in the canopy"s slippery heights.Desktop Version

Mesquite Flat Sand Dunes in Death Valley National Park, California
The Mesquite Flat Sand Dunes, located near Stovepipe Wells Village in Death Valley National Park, are the most accessible and iconic dunes in the park.

Today, the National Park Service celebrates another trip around the sun—and nearly 85 million acres of American beauty under its care. From geysers that spout like soda cans to ancient cliff dwellings tucked into canyon walls, the NPS has spent over a century preserving, protecting, and inviting people to take a hike—literally. In 1916, President Woodrow Wilson signed the Organic Act into law, officially creating the NPS to "conserve the scenery and the natural and historic objects." Since then, the NPS has grown to oversee more than 400 sites, including national parks, battlefields, monuments, and seashores.Desktop Version

World Bee Day
World Bee Day
Honey bees may be small, but without them, your grocery list would be a lot shorter. No more berries, avocados, or even coffee. Alongside butterflies, bats, and hummingbirds, bees pollinate nearly 90% of the world"s wild flowering plants and over 35% of the food crops we rely on. World Bee Day, marked every May 20, honors these vital pollinators and celebrates Anton Janša, a pioneer of modern beekeeping. Janša saw bees as the noblest of insects, an idea now backed by science.Desktop Version

Formal garden at Château de Villandry, Loire Valley, France
The grass truly is greener on the other side—especially when that side is Château de Villandry. While the Loire Valley in France is packed with stunning châteaux (French for castles), Villandry stands apart, not for its towering turrets or medieval might, but for its gardens. Built in the 16th century by Jean le Breton, a minister to King Francis I, Villandry was always meant to impress. Unlike fortified castles built for war, it was designed for comfort, featuring large windows and an open, welcoming layout. Its gardens are arranged across terraces with distinct themes. The ornamental garden showcases geometric patterns like the one pictured here. The water garden offers a serene retreat, and the vegetable garden turns everyday crops into artistic displays.Desktop Version
A wheatear in Peak District National Park, England
A wheatear in Peak District National Park, England
You don"t need to be a bird expert to notice the wheatear darting across open ground. These ground-dwelling songbirds are known for their upright posture and habit of hopping or sprinting between perches. Despite the name, wheatears have nothing to do with wheat or ears—the name is a twist on the old phrase "white arse," pointing to the bird"s distinctive white rump found in most species. The northern wheatear weighs less than an ounce, but travels thousands of miles between its summer homes in Alaska and northern Canada to its wintering grounds in Africa. Its migration route is one of the longest for a bird its size. Unlike many backyard songbirds, wheatears prefer wide-open spaces with low vegetation, where they can sprint and pounce on insects. And while most North American birders might only catch them in the far north, wheatears are widespread across Europe, Asia, and Africa.Desktop Version

Delicate Arch, Arches National Park, Utah
Delicate Arch, Arches National Park, Utah
This place wasn"t built overnight—nature took its time to craft this masterpiece. What you see at Arches National Park, Utah, is the result of over 300 million years of erosion, uplift, and weathering. These arches were formed when salt beds were left behind by ancient seas. Over time, layers of sandstone cracked, shifted, and slowly wore away, revealing more than 2,000 natural arches. These formations are made mostly of Entrada and Navajo sandstone. The park was recognized as a national monument in 1929 and was later upgraded to national park status in 1971.Desktop Version
