Glacial rivers in Iceland
Glacial rivers in Iceland
Iceland"s glacial rivers have shaped the landscape here in the land of fire and ice over thousands of years. The rivers seen in today"s image are formed from the meltwater of vast glaciers like Vatnajökull, Langjökull, and Hofsjökull. Vatnajökull, the largest ice cap in Iceland, covers over 3,000 square miles—approximately 10% of the country"s landmass. As the glaciers melt, the water carries fine sediments, creating a braided river system with a milky appearance that contrasts with the earthy tones of the volcanic terrain. Every spring and summer, the rivers swell with seasonal meltwater, continually shaping and reshaping the land. Aerial views reveal their intricate patterns, interwoven across the terrain toward the North Atlantic Ocean. The water also powers hydroelectric power stations, reinforcing Iceland"s status as a leader in sustainable energy.Desktop Version
World Meteorological Day
World Meteorological Day
"When clouds appear like rocks and towers, the Earth"s refreshed with frequent showers." There"s a whisper of truth to this old proverb for the storm clouds, also known as cumulonimbus or anvil clouds, which are pictured here. Today, on World Meteorological Day, we honor the marvel that is our atmosphere. This observance, first held in 1961, commemorates the establishment of the World Meteorological Organization and recognizes the vital role meteorology plays in our lives.

Arches National Park anniversary
Arches National Park anniversary
Red as far as the eye can see and clear blue skies overhead. Welcome to Arches National Park, Utah. The story of this otherworldly landscape starts 65 million years ago when a dry seabed stood here. Over time, geological forces warped and squeezed the land, twisting the sandstone into lumps and bumps. Later, wind and water carved out the arches, pinnacles, fins, and balanced rocks that now stand in this area. The park has more than 2,000 natural stone arches, the highest concentration of these structures anywhere on Earth. In today"s image, we can see two of them: Double Arch, as seen through Cove Arch. The larger arch of Double Arch spans 144 feet and is 112 feet tall, the tallest and second-longest of the park"s arches.Desktop Version

Sandstone formations in the badlands near Caineville, Utah
Sandstone formations in the badlands near Caineville, Utah
Wavy sandstone ridges stretch across the Caineville Badlands, Utah, resembling nature"s brushstrokes on stone. These formations are made of fine-grained sediment that settled in ancient river deltas and inland seas and later hardened into stone. Over time, erosion carved through the layers, exposing flowing, ripple-like patterns. The sedimentary layers tell a story of shifting climates and ancient landscapes. The barren land, seen in today"s image, may appear lifeless, but during early spring, rainfall blankets the terrain with tiny purple and yellow flowers. Light and shadow shift throughout the day, offering photographers and visitors various angles. While much of the terrain remains rugged, some areas offer easy access, allowing visitors to explore without strenuous hiking.Desktop Version

National Bison Day
National Bison Day
Once upon a time, in the boundless grasslands of North America, there roamed creatures of great strength and majesty—the American bison. These animals were a key part of life for many Native American tribes, providing food, clothing, and tools. Their population dwindled perilously low in the late 1800s, falling from as many as 60 million to fewer than 1,000 due to excessive hunting and disease. Enter a group of conservationists, ranchers, and Native Americans who stepped in to save the species. Now, over 500,000 bison roam again, many in protected areas like Yellowstone National Park, featured in today"s image. Today, on National Bison Day, observed every first Saturday in November, we honor these noble creatures—a testament to the American spirit and the monumental conservation efforts to save them.Desktop Version

US Election Day
US Election Day
It"s time to get out and vote! In 1845, Congress designated the first Tuesday after the first Monday in November as the day Americans vote for most federal offices.

For convenience and to save money, many elections for state and local offices are also held on Election Day.Desktop Version
The Sonoran Desert, Arizona
The Sonoran Desert, Arizona
Welcome to the Sonoran Desert, where life thrives despite the heat thanks to two seasons of rainfall. This subtropical desert spreads across parts of Mexico, California, and Arizona and is home to animals such as roadrunners, Gila monsters, and the Morafka"s desert tortoise. Its rainy seasons are followed by the blossoming of colorful wildflowers such as the brittlebush, seen in today"s image. These hardy shrubs are adapted to the dry seasons, with their silvery-gray leaves covered in fine hairs that help reduce water loss. Brittlebushes produce bright yellow flowers that bloom in clusters, adding splashes of color to the desert landscape. Another drought-loving desert flora is the saguaro cactus, which can live for over 150 years and grow up to 40 feet tall. The saguaro also provides food and shelter for desert species and is a sacred plant in the culture of the Tohono O"odham people.Desktop Version
National Find a Rainbow Day
National Find a Rainbow Day
Have you ever spotted a rainbow and felt a little lucky? National Find a Rainbow Day, celebrated today, is all about looking to the sky for that magical mix of sun and rain. Nature"s color wheel has long been linked to myths and legends, from Norse gods to the Irish leprechaun"s pot of gold. But beyond folklore, the science behind rainbows is just as compelling. The first real explanation came from Theodoric of Freiberg, a German physicist, in 1304. He discovered that rainbows form when sunlight enters a raindrop, bends, reflects inside, and then bends again as it exits. This process splits light into its colors, creating the spectrum we see. The classic "ROYGBIV" (red, orange, yellow, green, blue, indigo, and violet) doesn"t tell the whole story—rainbows contain millions of colors blended together.Desktop Version
