Four Sisters, thousands of trees
Four Sisters, thousands of trees
You"ll find this wintry, sylvan scene on the slopes of Mount Siguniang, the tallest summit of the Qionglai Mountains in southwest China. Its name, which translates as "Four Sisters Mountain," is inspired by the local Tibetan legend behind its four distinct peaks. According to the story, four sisters saved their people using a magic mirror to turn themselves into the mountain to imprison the devil. The tallest peak, named "Peak of the Youngest Sister," stands at 20,500 feet and is an extremely challenging climb—it"s rarely attempted and wasn"t summitted until 1981. The national park includes three valleys flanking the mountain and is part of the Sichuan Giant Panda Sanctuaries, a UNESCO World Heritage Site. In addition to giant pandas, the sanctuary is home to the red panda, the snow leopard, the clouded leopard, and between 5,000 and 6,000 species of plants.Desktop Version
A bridge comes full circle
A bridge comes full circle
If residents of Aarhus, Denmark"s second-largest city, feel like they"re going around in circles, then it might have something to do with this wooden walkway. The Infinite Bridge, or "Den Uendelige Bro" to locals, is about 200 feet in diameter. It forms a perfect circle overlapping the sand and sea, offering sweeping views across Aarhus Bay and along the tree-lined beach. Designed by Danish architects Niels Povlsgaard and Johan Gjødes, it was originally constructed as a temporary display in 2015 for the city"s Sculpture by the Sea exhibition. But the never-ending pier proved so popular, the city now opens the bridge to circular meandering each spring and summer.Desktop Version
Signs of life in the Empty Quarter
Signs of life in the Empty Quarter
An unlikely tree stands amid the seemingly endless dunes of the Rub" al Khali desert in the Arabian Peninsula. The Rub" al Khali, meaning "Empty Quarter" in Arabic, is a vast sea of sand. Spreading across 250,000 square miles, it"s the largest area of continuous sand in the world, covering most of southeastern Saudi Arabia, with smaller portions in Yemen, Oman, and the United Arab Emirates. One of the driest places on Earth, almost no one lives in the Rub" al Khali, and much of the desert remains unexplored. Some of the dunes tower more than 800 feet, and the depressions in between—called sabkhas—can be so soft that vehicles, camels, and people can easily become stuck.Desktop Version

A water loch-ed castle
A water loch-ed castle
Located on a small island where three sea lochs meet in northwestern Scotland, the current Eilean Donan Castle is just the latest incarnation of several monastic cells and Scottish clan strongholds that have occupied the tidal islet since the 7th century. The first fortified castle was built in the 13th century to defend against invading Vikings who occupied much of Scotland at the time. An iconic symbol of Scotland, from the 14th to 18th centuries the castle was mostly held by the Mackenzies and defended by the MacRaes, both storied clans of the Scottish Highlands. The castle was destroyed in 1719 by the invading British Royal Navy during the Jacobite Uprising, but was rebuilt along its earlier design in the early 20th century by Lt. Colonel John MacRae-Gilstrap.Desktop Version
Great Salt Lake Shorelands Preserve in Layton, Utah
Great Salt Lake Shorelands Preserve in Layton, Utah
There are at least 27 private reserves along the shores of Utah’s Great Salt Lake. This one, owned by the Nature Conservancy, stands in a marshland that’s an important rest stop for birds migrating on the Pacific Flyway path. The Pacific Flyway runs from Alaska all the way down to Patagonia in South America. It’s one of four major north-to-south migration routes for birds. Nature preserves like this keep important points along the flyway intact and undeveloped.Desktop Version
It’s National Walk to Work Day
It’s National Walk to Work Day
Every year approximately 4,000 pairs of emperor penguins trudge across the frozen landscape to reach Snow Hill Island, turning this snowcapped island off the east coast of the Antarctic Peninsula into a crowded breeding colony. While there, the male penguin’s job is to carefully guard the egg his mate has laid, and make sure it stays warm enough so the chick inside can hatch. If your job doesn’t take you to a snow-covered Antarctic island, then why not celebrate by observing National Walk to Work Day today?Desktop Version
We have liftoff!
We have liftoff!
The Wright brothers documented the first sustained flight in a powered, controlled aircraft on this day in 1903. That historic achievement was the result of single-minded perseverance, study, and experimentation. The brothers had spent more than a dozen years designing, engineering, constructing, and tweaking various test craft, including groundbreaking work done on the glider shown here. Orville Wright snapped this photo of the plane as it’s piloted by his brother Wilbur, gliding down the slope of Big Kill Devil Hill in Kitty Hawk, North Carolina, in October 1902.Desktop Version
Spring comes to the Diablo foothills
Spring comes to the Diablo foothills
Spring rains carpet the rolling foothills of Northern California"s Diablo Range in emerald green this time of year. Just past the sprawling suburbs of the East Bay region, the Diablo foothills become a sylvan playground for horseback riding, hiking, bicycling, and simply escaping into nature. Grasslands and oak savannahs cover the low ridges that gradually rise into the higher peaks of the range, and at the crests of the foothills, a visitor is granted panoramic views of the ridgeline to the east. Aside from the green grasses, springtime brings a profusion of wildflowers to the area, including poppies, daffodils, and lupines. It"s also nesting season for the many birds of the region, like the peregrine falcons that build nests high in the vertical rock formations here known as Castle Rock.Desktop Version
A bridge too Fawr
A bridge too Fawr
How much quaintness can be crammed into one picture? We"re pushing the limits with this verdant summer scene in North Wales, looking across the River Conwy from its east bank in the town of Llanrwst. Past the Pont Fawr (Big Bridge) in the foreground, the shrubbery-shrouded cottage dubbed Tu Hwnt I"r Bont (Beyond the Bridge) seems to sprout straight from the grass. Built in the 15th century as a farmhouse, it"s now a traditional Welsh tearoom serving up scones to locals as well as visitors bound for nearby Snowdonia National Park.Desktop Version
The Pearl of Siberia
The Pearl of Siberia
Russia"s Lake Baikal is a record-holding wonder: It"s the world"s oldest (25 million years), deepest (over 5,000 feet in some parts), and largest freshwater lake (more than 20 percent of the Earth"s fresh surface water by volume). Baikal lies in the deepest continental rift on Earth, and because the rift is geologically active, the tectonic plates continue to move farther apart.Desktop Version
The story of the poinsettia
The story of the poinsettia
The winter holidays are the poinsettia’s time to shine. Today, National Poinsettia Day marks the anniversary of the death of Joel Roberts Poinsett, the physician and botanist who first introduced the colorful plant to the United States in 1828. He discovered the plant while he was serving as the first US ambassador to Mexico, the plant’s native country, where Aztecs once used it to produce red dye. According to legend, the poinsettia’s association with Christmas began in 16th-century Mexico, where a little girl—too poor to buy a gift—gathered weeds from the roadside and placed them in front of a church altar. They eventually produced lovely red leaves alongside the green ones, and the poinsettia plant was on its way to becoming a Christmas tradition.Desktop Version

On New Zealand"s North Island, Whakarewarewa Forest is home to a diverse range of native plants and animals. There"s also a series of lakes as well as hot springs, bubbling mud pools, and even active geysers. But Whakarewarewa Forest features something that no other forest in New Zealand can claim: a stand of majestic redwood trees called the Redwood Memorial Grove. The redwoods were introduced from their native California at the beginning of the 20th century.Desktop Version

Montreux, Switzerland, and all that jazz
We’re looking at Montreux, Switzerland, where the Montreux Jazz Festival begins today. Despite its name, the festival isn"t just about jazz. It highlights different styles of music across multiple venues over two weeks. This year"s lineup includes three farewell-tour stops (Elton John, Anita Baker, Joan Baez) and big names in jazz (Chick Corea, Bobby McFerrin), as well as young artists representing a variety of genres. The festival began in 1967 at the original Montreux Casino, which famously burned down during a December 1971 Frank Zappa performance. The fire was memorialized by Deep Purple in their hit "Smoke on the Water." A monument commemorating the band and their song can be found next to the rebuilt casino.Desktop Version
Happy Independence Day!
Happy Independence Day!
All across the United States on July 4, we come together as a nation to celebrate the signing of the Declaration of Independence in 1776. In it, the Second Continental Congress put Great Britain on notice that the 13 American colonies were no longer subject to its laws and instead had formed a new country, the United States of America. Declaration signers, recognizing the importance of the moment and the message, anticipated that generations later we would remember and celebrate "from one end of this continent to the other." The celebration we"re looking at here is in San Francisco, where crowds traditionally gather at various spots along the waterfront area to take in the annual fireworks display over the bay.Desktop Version
An ancient sailing tradition takes to the water
An ancient sailing tradition takes to the water
During Asian American and Pacific Islander Heritage Month, we"re turning our attention to this vessel setting sail from Honolulu. It looks like a sailboat at sunset, accompanied by a group of rowers. But this is actually the Hōkūle"a, a replica of a traditional Polynesian voyaging canoe, as it departs in May 2014 for a three-year "Mālama Honua" voyage to circumnavigate the world. The Polynesian Voyaging Society, which organizes the expeditions of the Hōkūle"a, explains that "Mālama Honua" means to "care for our Island Earth." As they sail around the world, they"re discovering and sharing local and Indigenous wisdom in a bid to help overcome the world"s current challenges.Desktop Version
Life in the slow lane
Life in the slow lane
In observance of Manatee Awareness Month, we"re swimming through clear, aquifer-fed spring waters in Florida with two friendly "sea cows." Generally solitary animals, manatees are also known to be curious and will approach boats. That"s why Florida enforces special speed zones for watercraft, particularly as the manatees are on the move to warmer areas to spend the winter. While manatees have no known natural predators, they remain a vulnerable species due to loss of habitat and collisions with boats. These two have arrived in Three Sisters Springs, a natural freshwater spring system in the Crystal River National Wildlife Refuge on the west coast of the Florida Peninsula. The refuge protects critical habitat for the hundreds of manatees that migrate here each winter.Desktop Version
Monet still makes an impression
Monet still makes an impression
Was there frost in your neighborhood this morning? More than 100 years ago, impressionist painter Claude Monet painted this wintry scene, called ‘The Frost,’ in the French commune of Vétheuil, where he lived from 1878 to 1881. We’re showing it today in honor of his birthday. Monet is considered a father of impressionism, the artistic movement characterized by thin brushstrokes and depicting the visual impression of the moment–especially in terms of light and color. The term impressionism derives from a review of Monet’s painting ‘Impression, Sunrise,’ which he exhibited in 1874. Happy birthday, Claude!Desktop Version
National Park Week: Everglades National Park
National Park Week: Everglades National Park
You’re looking at a satellite view of Florida’s Everglades, the largest subtropical wilderness in the US. It’s not a static wetland, but rather a ‘river of grass,’ a slow-moving river 60 miles wide and 100 miles long. Keep zooming in and you’ll likely see sawgrass marshes, mangrove trees, tropical birds, and a gator or two. Among the myriad interesting things about this unique and fragile ecosystem—it’s the only place in the world where American alligators and American crocodiles co-exist. How do you tell the difference between the two? Well, you see one later and the other after a while. (See what we did there?)Desktop Version
A night of art and culture
A night of art and culture
The arts festival known as Blaue Nacht, or Blue Night, was originally conceived as a one-time event in 2000 to mark the 950th anniversary of the founding of Nuremberg, Bavaria. That inaugural festival was popular enough that it became an annual event soon after, and attendance has grown each year since. More than 100,000 people attend this celebration of the city"s diverse arts and culture each May. The two-night artfest includes light shows projected on the outside of Old Town buildings, music performances, temporary art installations—like "Waldplastik" in today"s image—and access to Nuremberg’s cultural sites.Desktop Version

Southern lights for Antarctica Day
In honor of Antarctica Day, you"re seeing the southern lights dazzle above Halley VI, the latest version of the six-decade-old Halley Research Station in the British Antarctic Territory. The modular building stands on hydraulic legs and is movable via retractable skis. The five previous facilities, Halley I–V, were each compromised by Antarctica"s harsh climate and decommissioned. Since 2017, when scientists discovered dangerous cracks in the surrounding Brunt Ice Shelf, Halley has been unmanned during the dark Antarctic winter months—but the research team equipped it with an autonomous micro-turbine that keeps its atmospheric instruments ticking as the snowdrifts pile up.Desktop Version
Pining for spring
Pining for spring
Next time you"re out walking amid the verdant majesty of a conifer forest, take a moment to consider the small but mighty pine cone. It plays a crucial role in the trees" lifecycle but has also served as a potent symbol for a variety of human cultures. In many traditions, it"s been associated with fertility and enlightenment, appearing in art from the Mayans, Egyptians, Greeks, and Romans. That association comes from its main job—making baby trees. The ornate, woody pine cones shown here are females, and they"re designed to create and protect seeds. Male cones, which are usually smaller, produce pollen. The female cones open and close their scales to allow for pollination and eventually release their seeds onto the forest floor. But pine cones also open and close in response to changes in the weather, making them a natural barometer.Desktop Version

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

Cloudy with a chance of enlightenment
While it didn"t become a UNESCO World Heritage Site until 2018, Buddhists have considered Mount Fanjing (also known as Fanjingshan) a sacred and tranquil site for centuries. At 8,430 feet, Mount Fanjing is the highest peak of the Wuling mountain range in southwest China"s Guizhou province. While many of the Buddhist temples built here have been destroyed, several remain, including the Temple of the Buddha and the Temple of Maitreya. Those two temples, linked by a small bridge, are located on top of Red Cloud Golden Peak, the rocky "thumb" we"re looking at here. In addition to the area"s history, the mix of clouds, fog, and light creates a calming atmosphere and an air of mystery.Desktop Version
The confluence of the Arve and Rhône Rivers
The confluence of the Arve and Rhône Rivers
That’s the Arve river on the right, flowing into the Rhône. This point where the two rivers meet is just west of the city center in Geneva, Switzerland. The Arve’s much lighter color is due to the silt it picks up as it flows out of the Alps. From here, the Rhône will continue on—in a mostly southerly direction—through southeastern France toward its mouth on the Mediterranean Sea.Desktop Version
