World Bee Day
World Bee Day
A soft buzz and a dusting of pollen can shape the future of our food. World Bee Day, observed each year on May 20, celebrates pollinators like the bumble bee pictured here during its quiet yet essential work. Unlike many insects, bumble bees use "buzz pollination," vibrating their flight muscles to shake pollen from flowers—a method vital for crops such as tomatoes, peppers, and blueberries.Desktop Version

World Turtle Day
World Turtle Day
Turtles are not only fascinating animals; they also play vital roles in nature. Sea turtles help keep seagrass beds and coral reefs healthy, while freshwater and land counterparts support balanced ecosystems. Their shells are part of their skeletons, formed from dozens of fused bones, and some species navigate using Earth"s magnetic field to return to the beaches where they hatched.Desktop Version

Memorial Day honors the men and women who lost their lives while serving in the United States Armed Forces. Observed on the last Monday in May, the holiday traces its origins to the years following the Civil War, when communities began decorating the graves of fallen soldiers.

Old city wall of Hwaseong Fortress, Suwon, South Korea
Old city wall of Hwaseong Fortress, Suwon, South Korea
As night settles over Suwon, South Korea, the old city wall pictured here shows that function doesn"t necessarily cancel out beauty—it can create it. Built between 1794 and 1796 under King Jeongjo of the Joseon Dynasty, Hwaseong Fortress was more than a barrier. It was policy in stone: a reform minded push for a leaner, better-run state, driven by practicality and a deeply personal motive. Jeongjo ordered its construction to honor his father while strengthening a kingdom that wanted smarter systems, not just thicker walls.Desktop Version
World Oceans Day
World Oceans Day
Today is World Oceans Day, so follow the lead of a creature that goes wherever the water takes it. Want to spot a lion"s mane jellyfish? Look in cold northern seas. Its bell is split into eight lobes, and beneath it hang long tentacles and oral arms. As it drifts with the current, stinging cells snare plankton and small fish. For humans, the sting can be painful. Reactions vary, and even a washed-up tentacle can still hurt. The rule is simple: admire it, then leave it alone. Some lion"s manes in Arctic waters have bells more than 6 feet across, but most sightings are smaller animals near shore after storms or strong currents.Desktop Version

1953 Mount Everest Expedition
1953 Mount Everest Expedition
In Sagarmatha National Park, Nepal, Mount Everest rises into view, calm and unmoved as evening settles in. But on May 29, 1953, that stillness was broken. After years of planning and weeks of climbing, New Zealander Edmund Hillary and Sherpa mountaineer Tenzing Norgay reached the summit. At over 29,000 feet above sea level, they became the first people known to have stood at Earth"s highest point.Desktop Version
Highway through Xitai Jinaier Lake, Qinghai Province, China
Highway through Xitai Jinaier Lake, Qinghai Province, China
Cutting a surreal path through the high-altitude deserts of western China, Xitai Jinaier Lake (also known as West Taijinar Lake) is a striking salt lake in the remote Qaidam Basin. A stretch of National Highway 315 runs directly across its shallow waters, creating the illusion of a road floating between two worlds. On one side, the water often appears deep blue; on the other, a softer green hue, a contrast shaped by differing mineral concentrations in the brine.Desktop Version
World Environment Day
World Environment Day
If nature had a "do not disturb" sign, it would hang over Sarek National Park, often called "the last European wilderness." On World Environment Day, this remote corner of Swedish Lapland reminds us what the planet looks like when humans take a step back—and let the wild take the lead.Desktop Version
Happy Pride Month!
Happy Pride Month!
Every June, Pride Month bursts into cities and streets across the United States—but its origins lie in defiance, not festivity. The observance grew from the Stonewall uprising of June 1969, when LGBTQIA+ New Yorkers pushed back against routine police raids, igniting a movement that reshaped civil rights history.Desktop Version
National Trails Day

Snowy egret preening, central Florida
Snowy egret preening, central Florida
Poetic name, poetic appearance. Meet the snowy egret, whose all-white plumage and bright yellow "slippers" on black legs give it a striking look. Once nearly wiped out by demand for its delicate breeding-season feathers—soft, lacy plumes prized for fashionable hats—conservation efforts saved its plumage.Desktop Version

Hnausapollur crater lake, Fjallabak Nature Reserve, Iceland
From above, the lake"s smooth surface contrasts sharply with the rugged ground surrounding it. Hnausapollur crater lake—also known as Bláhylur—lies in the heart of Fjallabak Nature Reserve, a remote area of Iceland"s highlands shaped more by volcanic activity than by human settlement. The crater formed when magma met groundwater, triggering an explosion that carved out the circular basin visible today.Desktop Version
End of American Wetlands Month
End of American Wetlands Month
Today is the last day of American Wetlands Month, but don"t let that bog you down. Take today to shine a spotlight on wetlands. Held throughout May, this national observance shines a spotlight on wetlands—some of the most productive ecosystems in the United States—and few places show their power quite like Everglades National Park. From above, Florida"s iconic wetlands unfold as a vast patchwork of shallow water, sawgrass, mangroves, and winding channels, shaped by freshwater slowly flowing south from Lake Okeechobee.Desktop Version
Limpets at low tide on the coast of Praia da Ursa, Portugal
Limpets at low tide on the coast of Praia da Ursa, Portugal
Tucked away beneath steep cliffs near Cabo da Roca, the westernmost point of mainland Europe, Praia da Ursa feels like the edge of the continent. Reached by a narrow, rugged trail, this secluded beach along Portugal"s Atlantic coast is shaped largely by wind, stone, and powerful waves. When the tide recedes, the shoreline briefly widens. Smooth rocks emerge, and with them, small signs of life. Limpets cling tightly to the exposed stone, holding fast where the ocean usually breaks.Desktop Version

European bee-eater, Sierra de Grazalema Natural Park, Cádiz, Spain
A streak of color glides past a blur of wildflowers as a European bee-eater cuts through the air. Turquoise, gold, and chestnut shimmer across its wings as it hunts in flight, snatching insects midair with swift turns. Bees and wasps are among its favored prey, and the bird often removes the stinger before feeding—a behavior that reduces the risk of injury.Desktop Version
Plains zebra foal in Etosha National Park, Namibia
Plains zebra foal in Etosha National Park, Namibia
Etosha National Park, Namibia, is not a place for soft starts, and the plains zebra foal in this image seems to get the memo. In a land this vast—nearly 8,600 square miles of salt pans and grassland—timing is everything, and hesitation is expensive. Lions, spotted hyenas, wild dogs, cheetahs, and leopards constantly pressure the herd—especially the youngest—so zebras are born ready. Minutes after arrival, they"re upright. Hours later, they"re moving.Desktop Version
Sunset in Badlands National Park, South Dakota
Sunset in Badlands National Park, South Dakota
Layered ridges stretch across Badlands National Park in South Dakota. Their bands of pink, gray, and gold shift with the light as eroded peaks and valleys come into view. Wind and water continue to shape this terrain, steadily wearing away soft sedimentary rock and exposing millions of years of Earth"s history in layers formed by ancient rivers, volcanic ash, and periods when shallow seas covered the region.Desktop Version
Great Smoky Mountains National Park turns 92!
Great Smoky Mountains National Park turns 92!
These mountains were shaped over time—and June 15, 1934, helped protect them. That"s when the Great Smoky Mountains National Park was established in Tennessee and North Carolina. Covering over 522,000 acres, the park takes its name from the natural smoky haze drifting over its ridgelines. Part of the Appalachian Mountains, these peaks are over 300 million years old.Desktop Version
