National Garden Week
Since opening its doors in 1976, the Atlanta Botanical Garden has proven that beauty can be organized. Beds are planned, labels are placed, and every plant has a job. "To have a garden is not as easy as it seems; it is just as difficult as governing a kingdom." Nobel Prize-winning German author Hermann Hesse had a point.Desktop Version

Juvenile manatees in a freshwater spring, Crystal River, Florida
Manatees may seem slow and sleepy, but they have some surprising tricks under the surface. For starters, they are one of the few mammals that constantly replace their teeth. As old molars wear down from chewing gritty seagrass, new ones slowly roll forward like a conveyor belt—handy for an animal that eats for up to eight hours a day.Desktop Version

High above the savanna in Kenya"s Masai Mara, a leopard curls up on a tree branch, napping as the grasslands glow at sunset.

Leopards roam across Africa and parts of Asia, thriving in habitats that range from forests and mountains to open savannas. Their spotted coats are unique to each individual, like fingerprints, and their powerful climbing skills allow them to stash prey high in trees, out of reach of scavengers.Desktop Version

Celebrating Pi Day
Celebrating Pi Day
Long before pi had a name, people were drawn to its mystery. Every year on March 14, Pi Day highlights one of math"s most recognizable constants. The date reflects the first three digits of pi (π), the ratio of a circle"s circumference to its diameter: 3.14. Pi"s infinite, nonrepeating decimal has fascinated thinkers for a long time. The modern celebration began in 1988, when physicist Larry Shaw marked the day with a fitting tribute: serving pie.Desktop Version

Common clownfish in a sea anemone, Raja Ampat Islands, Indonesia
Sea anemones may look like underwater flowers, but they"re actually animals—close relatives of jellyfish and corals. Anchored to rocks or reefs, they use a sticky base and a crown of waving tentacles armed with tiny stingers to capture passing prey. Those stings can paralyze small fish, yet one famous neighbor is immune.Desktop Version

Lupine flowers in bloom, Northern California
As spring sweeps across Northern California, the landscape is transformed by the vibrant displays of lupine flowers in shades of blue, purple, and white. Flourishing in the region"s Mediterranean climate, these wildflowers provide a vital source of nectar for pollinators such as bees, butterflies, and beetles. With over 200 species found worldwide, lupines range from coastal varieties to those that thrive in mountain meadows. Beyond their striking beauty, lupines are essential to the ecosystem: by fixing nitrogen underground, they enrich soil fertility and support the growth of surrounding plants, even in nutrient-poor environments.Desktop Version
Third Thai-Lao Friendship Bridge connecting Laos and Thailand
Third Thai-Lao Friendship Bridge connecting Laos and Thailand
Before bridges, rivers set the pace of travel. Now, with bridges, people do. That shift explains why cross-border links like the Third Thai-Lao Friendship Bridge connecting Laos and Thailand matter. Bridges come in many forms, each built to meet a specific challenge. Arch bridges manage compression, suspension bridges span long distances, and concrete box-girder bridges prioritize stability and load efficiency. This bridge uses the box-girder design, making it a practical choice for crossing the wide, fast-moving Mekong River.Desktop Version

Formentor Lighthouse, Mallorca, Balearic Islands, Spain
Formentor Lighthouse, Mallorca, Balearic Islands, Spain
At Mallorca"s far northern tip, in Spain"s Balearic Islands, the Formentor Lighthouse stands on the sheer cliffs of Cap de Formentor. This exposed headland is often called the "Meeting of the Winds." Built in 1863 and first lit on September 30 of that year, the lighthouse rises nearly 700 feet above the Mediterranean Sea and is reached by a narrow, switchback road about 8 miles from Port de Pollença. Under your feet is pale limestone—rock formed from ancient marine life and later lifted and carved by erosion into dramatic faces, sea caves, and natural arches. This rugged geology gives rise to the area"s stark beauty and sense of isolation. Want to earn the view? Follow one of the peninsula"s hiking routes, or tackle the short, steep climb to Talaia d"Albercutx for a watchtower panorama before continuing to the lighthouse. Keep an eye on the slopes: wild goats, descended from early domestic herds, spring across the ledges with effortless balance.Desktop Version

Milwaukee City Hall, Wisconsin
Milwaukee City Hall, Wisconsin
If you"ve ever wandered through downtown Milwaukee and looked up in awe, chances are you were staring at the iconic Milwaukee City Hall. Completed in 1895, this towering Flemish Renaissance Revival masterpiece doesn"t just dominate the skyline; it defines it. For nearly eight decades, it stood as the city"s tallest building, a title it proudly held until 1973. Designed by architect Henry C. Koch, this hall blends German-inspired architecture with Milwaukee"s own historic influences. That connection isn"t accidental—its design pays tribute to the city"s strong German heritage, which shaped much of the surrounding neighborhood as well.Desktop Version

Bláhver, Hveravellir, Iceland
Bláhver, Hveravellir, Iceland
Have you ever wondered what happens when fire, ice, and time negotiate the same territory? Iceland"s Hveravellir geothermal field has the answer. In this highland hotspot, energy from the Earth"s interior meets the icy surface, triggering a volatile dialogue between pressure, temperature, and stone. Fumaroles hiss, steam curls into the air, and the ground paints itself with sulfur whites, rust reds, and ochre yellows—not only artistry, but chemical reactions driven by extreme heat. In today"s image, Bláhver, a natural hot spring, dazzles in electric blue. Its color comes from mineral- and silica-rich waters that reflect light on the surface.Desktop Version
