A wild and scenic scene
A wild and scenic scene
Some of our nation"s most treasured rivers are protected thanks to a program that was first established on this day in 1968. The Wild and Scenic Rivers Act aims to preserve rivers with "outstanding natural, cultural, and recreational values in a free-flowing condition for the enjoyment of present and future generations." That"s something we can get behind.Desktop Version
In the belly of Fat Bear Week
In the belly of Fat Bear Week
In Alaska"s Katmai National Park and Preserve, the "fattening" is under way. Brown bears like our homepage friend are bulking up for the long winter, gathering at Brooks Falls to feast on migrating salmon. The base of the falls is a prime fishing spot because it creates a temporary barrier to salmon jumping upstream. This makes the fish relatively easy pickings for hungry bears, who can catch up to 30 salmon a day.Desktop Version
Infrared Jupiter, erupting Io
Infrared Jupiter, erupting Io
To celebrate World Space Week, we"re featuring this montage of images of Jupiter courtesy of the New Horizons probe"s flyby of the planet in 2007. If Jupiter looks a little different than you"re used to seeing, it"s because it was imaged using the space probe"s near-infrared imaging spectrometer. In this false-color image, Jupiter"s high-altitude clouds, like its stormy Great Red Spot, are rendered white, while deeper cloud formations take on reddish hues. The planet"s innermost moon, Io, is captured in a true-color composite image during one of its frequent volcanic eruptions. A close look will show lava is glowing red beneath the blue and white plume of particles being ejected into the moon"s thin atmosphere.Desktop Version
Hey, you two in the front!
Hey, you two in the front!
For World Teachers" Day, we"re taking you to a class of emperor penguin chicks getting a lesson from a couple of wise adults—at least that"s how it looks to us. All kidding aside, the celebration has a special significance this year. Educators dedicate their lives to engaging the minds of young and old alike, all the while sparking curiosity about the world around us. But with in-person classes widely curtailed due to the coronavirus pandemic, many teachers have had to adapt their instruction methods by shifting to remote learning. More than ever we"re grateful for their efforts, including their support to parents who are contributing at home.Desktop Version
Water colors
Water colors
Xiechi Lake in Yuncheng, China, has such a high level of salinity, it"s sometimes called China"s Dead Sea. But unlike the Dead Sea in the Middle East, Xiechi Lake supports abundant microscopic life: algae and other microorganisms that have a high tolerance for the salt. In summer and autumn, the lake temperature is high enough to spark algae blooms, bringing a variety of intense colors to the lake water.Desktop Version
The circular castle of Cornwall
The circular castle of Cornwall
Many generations watched fog roll over this countryside long before the bellicose Norman visitors who built this fortress got the chance. The peninsula of Cornwall has been populated since the Mesolithic period 10,000 years ago, and is one of the traditional Celtic nations—areas of the British Isles and France where the Celts" culture survived Roman, Norman, and other outside influences despite repeated attempts at incursion.Desktop Version

You might look twice if you passed by this Technicolor sea creature gliding through the ocean water. In celebration of World Octopus Day, we"re marveling at a photograph of the rarely seen blanket octopus, near Palm Beach, Florida. The blanket octopus gets its common name from the sheets of webbing that stretch between some arms of the female, like the one pictured here. When threatened, it spreads out its arms, creating a blanketlike silhouette to intimidate would-be attackers.Desktop Version
Falling for Tennessee
Falling for Tennessee
Although it might not look like it in this image of a tranquil fall day, Roaring Fork in Great Smoky Mountains National Park has earned its ferocious name. The stream descends 2,500 feet over just 2 miles—a steep drop. After heavy rains, Roaring Fork transforms into a whitewater rush, the sound echoing off the mountainsides. But during drier spells, the stream quiets to more of a babbling brook, as seen here along the Roaring Fork Motor Nature Trail. The popular 5.5-mile loop drive passes waterfalls, well-preserved historic log cabins, and scenic overlooks of a forest that during this time of year reaches its fall color peak, exploding in bold yellows, oranges, and reds. These are just some of the things that make Great Smoky Mountains the most popular national park in the country.Desktop Version
Birds of a feather
Birds of a feather
Today is World Migratory Bird Day in Latin and South America, so to honor the occasion we"ve chosen these flamingos, rising above the Caribbean Sea off the coast of Venezuela. Changes in daylight hours and food availability can trigger seasonal migrations in many bird species, including flamingos. American flamingos like these will migrate relatively short distances, usually to ensure a steady food supply. Found mainly throughout the Caribbean, their range extends as far north as southern Florida.Desktop Version
A monastery in the mountain
A monastery in the mountain
Built into the side of a mountain in the Azat Valley of Armenia, the monastery of Geghard is one of the most-visited tourist destinations in the country. The location of the monastery has been inhabited for millennia and venerated by locals since the pre-Christian era due to the spring which emanates from one of the caves in the mountainside. The monastery was originally founded in the 4th century by Saint Gregory the Illuminator—the patron saint of the Armenian Apostolic Church—though none of the original buildings survive.Desktop Version
Indigenous Peoples Day
Indigenous Peoples Day
With this image of totem poles, carved and erected by Haida people in British Columbia, Canada, we"re touching on two important events in North America today, one in the United States and the other in Canada. In the US, an increasing number of Americans observe the second Monday in October as Indigenous Peoples Day, a celebration of Native American peoples and an implicit (and sometimes explicit) critique of the Columbus Day holiday. Observations of Indigenous Peoples Day reflect an effort to honor the tribes, nations, and cultures that existed in North America before the arrival of European settlers and have endured since then.Desktop Version
Where can you find a red fox?
Where can you find a red fox?
The biggest of all fox species, the red fox lives in many different habitats around the world, including forests, grasslands, deserts, and mountains. This fox is in the Netherlands, but red foxes can be found throughout most of Europe, as well as in temperate Asia, North Africa, and North America. A male fox is called a dog, and the female a vixen. A young fox is a kit, cub, or pup. Foxes live in groups called skulks. The red fox"s tail accounts for about a third of its length, and it can serve as a blanket, as well as a flag the fox raises to communicate with other foxes.Desktop Version

In praise of the old…the very old
What better way to honor National Fossil Day than with this amazing dragonfly! It"s rare to find one in such exquisite condition, but this one was discovered in Solnhofen, Germany, where limestone deposits preserved some of the most detailed fossils ever found—including the birdlike dinosaur called Archaeopteryx. This dragonfly was preserved in the Solnhofen limestone about 150 million years ago in the Jurassic Period. It measures about 5.5 inches across.Desktop Version

Today we"re looking out over Pisgah National Forest, which was established on this day in 1916. One of the first national forests established in the eastern United States, it comprises more than 500,000 acres of mountainous peaks, cascading waterfalls, and heavily forested slopes. With hundreds of miles of trails, Pisgah is a popular place for hiking, backpacking, road biking, mountain biking, fishing, and rock climbing.Desktop Version
Sitka shines on Alaska Day
Sitka shines on Alaska Day
In honor of Alaska Day, we"re in the harbor of Sitka, Alaska, which was the capital of Russian America in the 19th century, when it was called Novo-Arkhangelsk. It was here on this day in 1867 that officials of the Russian Empire formally transferred the Territory of Alaska to the United States in a sale for $7.2 million, or just around 2 cents per acre. It seems an astonishingly small price today, but at the time, opponents called it "Seward"s Folly" after then-Secretary of State William H. Seward, who negotiated the deal. Few Americans moved to the "Last Frontier" at first, but in the 1890s, when gold was discovered in the Yukon and Alaska, a rush of prospectors and others began a wave of settlers in the territory. Ever since, Alaska, with its vast natural resources and staggering beauty, has been a prized American domain and an enduring symbol of American wilderness.Desktop Version
A cliff-hanging complex of temples
A cliff-hanging complex of temples
Feast your eyes on the colorful Mati Si (Horse"s Hoof Temple) and its cliffside complex of sandstone grottoes and wooden pavilions. An indentation in the sandstone provides a clue to the mythical origin of the temple. One legend has it that a frightened longma—a winged dragon horse—visited here thousands of years ago and left its hoof mark in the rock as it landed. What you can"t see in our homepage image is the narrow network of tunnels cut into the cliff, connecting the seven floors and multiple grottoes to the Mati Si pagoda, which is 200 feet high and holds hundreds of Buddha statues.Desktop Version
Reflecting on fall
Reflecting on fall
Some of the best things about fall in many parts of the country are the amazing colorful displays across the landscape. While the trees here in Beaver Lake Nature Center, near Syracuse, New York, are already bare, the autumn ferns cast a radiant reflection on the water. This 661-acre natural area contains a 200-acre glacial lake that draws migrating Canada geese to its shores. Visitors may also see more than 200 other species of birds and over 800 varieties of plants. The nature center is a destination for cross-country skiing in the winter, while the summer months are popular for kayaking and canoeing.Desktop Version

Does this chameleon look a little insecure?
If it appears to be slinking away from the camera, maybe this chameleon is all too aware of the way some of us humanfolk see reptiles: as frightening at best, disgusting at worst. We know you die-hard reptile lovers are out there too, but it"s undeniable that reptiles" reputation among people has suffered thanks to popular villainous depictions—from "Anaconda" and "Godzilla" to the serpent encountered by Adam and Eve. Even our everyday language throws shade on this vast class of critters: When"s the last time you called someone "reptile" and meant it nicely?Desktop Version
Moving as one
Moving as one
After the nesting and breeding seasons of spring and summer have passed, starlings become highly social birds, often gathering in flocks that number in the thousands. These flocks sometimes take the form of a murmuration—when the birds form a group large and dense enough that they appear to move together as a single organism, even if the movements seem arbitrary. Though scientists still don"t quite understand how the individual starlings in a murmuration coordinate their tight, fluid formations, the behavior is thought to be a way to confuse predators.Desktop Version

75 years of the United Nations
75 years of the United Nations
We"re looking at the New York City skyline with the UN"s headquarters in the middle for United Nations Day, marking the anniversary of the date when the UN Charter entered into force. This year is a milestone 75th anniversary of the United Nations, which replaced the League of Nations as the world"s largest and most powerful intergovernmental organization. To mark the occasion, the UN launched its UN75 global dialogue initiative in January, and discussions have taken place around the world in settings ranging from classrooms to the UN General Assembly. COVID-19 has made some of these events a logistical challenge, but it"s also highlighted the need for countries to work together to face global issues. The UN website allows anyone to participate, with tool kits for dialogue, issues briefs, and other resources.Desktop Version
A most sincere pumpkin patch
A most sincere pumpkin patch
Ah, the perennial pumpkin patch. You might think the round orange gourds in today"s photo are vegetables, but botanists say pumpkins are actually the fruit of pumpkin vines. They"re considered fruit because pumpkins contain seeds and grow from the same part of the plant that produces flowers. And now, as Halloween nears, pumpkins are ripe for picking and carving into spooky jack-o"-lanterns.Desktop Version
