International Tiger Day — It"s International Tiger Day! A day to celebrate these magnificent animals and consider how best they can be protected. The largest wild cats in the world, all tiger species are endangered, facing challenges including habitat loss, the illegal wildlife trade, and poaching. The Bengal tiger, an iconic subspecies primarily found in India, is the star of today"s image. As apex predators, Bengal tigers play a vital role in maintaining ecological balance by controlling populations of deer, wild boar, and bison. With an estimated population in the wild of between 2,500 and 3,000, tiger conservation is crucial to secure the future of this majestic species.Desktop Version

Central Highlands of Vietnam — The woods are a tranquil place, but they can be scary for a lone wanderer. Out here, you could suddenly find yourself running from the Big Bad Wolf, trying to escape a witch"s clutches, or just plain old lost. Though often in the old stories, scary places like this are also where the hero overcomes a great obstacle or finds a valuable treasure. Could you be in luck?Desktop Version

A medieval celebration in the Mediterranean — That mighty fortress at the top of the hill is called the Cittadella—it"s a medieval fortified city at the geographical center of the island of Gozo. Gozo is the second-largest island in the Maltese archipelago (after the island of Malta itself), and despite all appearances it"s the less densely populated of the two.Desktop Version

Gifford Pinchot National Forest — Today we"re paying a visit to an "elder statesman" of the United States" national forests. Seen in today"s photo is Panther Creek Falls at Gifford Pinchot National Forest in Washington state. Officially, the forest was named in 1949 in honor of Pinchot, the first head of the US Forest Service. Located between Mount St. Helens to the west and Mount Adams to the east, the land was set aside as a place worth preserving as far back as 1897. But people had been living in the forest for more than 6,000 years. Archaeologists continue to make discoveries within the dense forest that teach us about the past lives of Native Americans.Desktop Version

Prayer flags in Phobjikha Valley, Bhutan — This kaleidoscopic column is made up of prayer flags, blowing in the breeze in the Phobjikha Valley, Bhutan. Prayer flags come in five repeating colors representing different elements in nature, blue for the sky, white for air, red for fire, green for water, and yellow for earth. The fluttering fabrics, inscribed with spiritual scripts, are usually raised during times of prosperity, such as on Bhutan"s Nyinlong, their traditional day of solstice, which takes place today. As the flags fade over time, adherents believe this signifies that the prayers have been heard and are being carried away by the wind, infusing the surrounding area with positivity and spirituality.Desktop Version

Aug 18, 2023Avatar Mountains, Zhangjiajie National Forest Park, China

These stunning stone spires, rising from the forest in China"s Hunan province, are said to have inspired the floating mountains of the movie "Avatar." There are more than 3,000 of these quartz-sandstone pillars in Zhangjiajie National Forest Park, often swathed in mist, part of a spectacular landscape that has inspired generations of painters. These days, they are popularly known as the "Avatar Mountains" and one, the 3,544-foot-high Southern Sky Pillar, was officially renamed as "Avatar Hallelujah Mountain" in 2010, the year after the blockbuster movie was released.Desktop Version

Day of the Dead — If you"ve ever been in Mexico during Day of the Dead festivities, then you"ve no doubt come across the beautiful orange flowers you see here. Marigolds are one of the main symbols of this festive, two-day celebration. The flowers are native to North America, and were deemed sacred by the Aztecs, who likened their bright colors to the sun. According to legend, those colors and the flowers" sweet aroma have the power to lure the souls of the dead back to this world from beyond.Desktop Version

Cenote near Puerto Aventuras, Mexico — Like a giant block of Swiss cheese, Mexico"s Yucatán Peninsula is riddled with holes called cenotes. Cenotes form when subterranean limestone dissolves, allowing underground water to penetrate. The rock above may cave in, forming a sinkhole that reveals the cool, often crystal-clear water. Other cenotes may remain below the surface, hidden and often unexplored. Cenotes vary in size from very small to several dozen yards across, and recent discoveries have shown that some cenotes lead to a series of underground cave systems that can span several miles in length.Desktop Version

Zion National Park, Utah — Today, we"re celebrating the 102nd anniversary of southwest Utah"s Zion National Park with a visit to its Subway slot canyon. Zion is defined by its breathtakingly steep red cliffs, its maze of sandstone canyons, and its waterfalls with colorful hanging gardens. Visitors here can trek for miles, ducking into crevices and resting in canyons once occupied by the Ancestral Puebloans.Desktop Version

Breckenridge, Colorado — Gold mining put this Rocky Mountain town on the map in the 1860s, but today the real gold is the powdery snow that falls liberally on the slopes that surround the town. Breckenridge is one of Colorado"s premier ski and snowboard destinations. The resort has 35 lifts servicing five peaks and 2,900 acres of terrain. The visitors—who also arrive in the summer to fish, cycle, and paddle—easily outnumber the 5,000 residents of this quaint village. The gold mines have long shut down, apart from hosting visits from tourists. The enduring value of Breckenridge is its natural beauty.Desktop Version

Ardez, Graubunden, Switzerland — Perched on a terrace above the Inn Valley at 4,790 feet, Ardez is a hidden gem in eastern Switzerland renowned for its deep cultural roots and stunning preservation of history. This picturesque village, starring in today"s image, showcases the rich traditions and unique language of Switzerland"s Romansh-speaking communities. Its homes are adorned with sgraffiti—decorative designs etched into plaster—and colorful murals, both iconic art styles of the Engadin region. Dating back to 840 when it was first referred to as Ardezis, the village"s history includes Steinsberg Castle, originally owned by the Bishop of Chur. Though destroyed during the Swabian War in 1499, the castle"s tower has been restored multiple times and stands today as a proud reminder of its past. In 1975, Ardez was chosen as a Swiss model village for its exceptional preservation efforts, which have kept its historic charm intact.Desktop Version

Fall for birding — This common loon is spreading its wings in the Superior National Forest in Minnesota, near the US border with Canada and along the northern bank of Lake Superior. As temperatures cool, the protected area becomes a birder"s paradise while migrating flocks stop over on their flights south. The Superior National Forest’s 3.9 million acres and 2,000 lakes offer the right combination of water, woods, and wetlands to support over 155 species of birds, the most avian diversity found in any US national forest.Desktop Version

Maybe we should be looking up — When it first flicked on the projector lights in 1930, the Adler Planetarium in Chicago was the only one in the Western Hemisphere, and it featured an innovative new lens imported from Germany. But the American public"s fascination with stars and distant worlds, it turned out, was skyrocketing. By 1934, the Adler had welcomed over a million visitors.Desktop Version

Happy Easter! — Humans have been decorating eggs for Easter for centuries, but decorated ostrich eggs have been found from as far back as 60,000 years ago, long before the Christian festival began. The Easter egg has long been a symbol of fertility and rebirth, but exactly why people started decorating them is unclear. One theory is that, because animal products were not eaten during the religious Lenten season, people would hard-boil the eggs and decorate them with dye and wax, until they could be eaten at Easter. A more opulent type of decorated egg, Fabergé eggs, were famously created as bejeweled Easter gifts to the Russian imperial family. Our homepage image shows eggs from Lithuania, where people use traditional methods to paint patterns with wax using sharp objects or etch patterns into dyed eggs.Desktop Version

Nature Photography Day — Towering trees, rushing streams, and luminous fireflies combine to create this magical landscape in Tennessee"s Great Smoky Mountains National Park. The park is famous for its firefly season between May and June when these "lightning bugs" gather to put on a light show as part of a mating display. Today, we celebrate the anniversary of this magnificent national park, as well as Nature Photography Day. There may be no better subject than the lightning bug to mark the day—as photography is the art of capturing light in lasting images.Desktop Version

The perfect canvas for an ancient text — Since 2009, the city of Durham has served as a grand stage for the biennial Lumiere Durham festival. During four days in November, works of "son et lumière"—a French phrase that means "sound and light"—provide spectators with new ways of viewing public spaces and buildings. Artists from around the world design large-scale light shows paired with narratives and sound effects. It"s become the UK"s largest light festival, and Lumiere Durham"s 10th anniversary, which begins today, promises to attract more than 200,000 people to enjoy the illuminated artworks along cobbled streets.Desktop Version

Antarctica Day — The windiest, coldest, and driest continent on Earth—Antarctica—was officially discovered in 1820. In the following decades, several countries organized expeditions to reach and explore the Antarctic ice sheets. The southernmost continent had no indigenous population and various nations claimed ownership. But in 1959, 12 countries signed the Antarctic Treaty, banning military activities and setting Antarctica aside for scientific research. Today, we celebrate the anniversary of this treaty, which now has 56 parties.Desktop Version

Siblings Day — We"re in Kenya"s Amboseli National Park today to celebrate Siblings Day with these baby African elephant twins and their mom. Siblings Day is celebrated every April 10 in parts of the US and other areas of the world. In 1995, Claudia Evart, who lost her siblings at a young age, created this holiday and established the Siblings Day Foundation, which is working to get the holiday officially recognized in the US alongside Mother"s Day and Father"s Day. India"s Raksha Bandhan is the oldest sibling holiday that is still widely observed today, usually falling in August. Hindu women commemorate this day by wrapping a band around their brothers" wrists as a sign of mutual care and respect. If this seems like too much, maybe just pick up the phone and give a loved one a call.Desktop Version

National Lighthouse Day — Happy National Lighthouse Day! A beacon, a warning, and a symbol of hope and home, lighthouses have existed for thousands of years. The earliest known was the Pharos of Alexandria, which stood an estimated 330 feet tall. Built by the ancient Egyptians in the 3rd century BCE, an open fire was lit at its highest part to guide ships into port. Illumination technology advanced over the centuries, culminating in today"s electric versions beaming light that can be seen from over 20 miles away. North Carolina"s Bodie Island Lighthouse, pictured here, was built in 1872 and overlooks a section of ocean once known as the Graveyard of the Atlantic. Since then, it"s been doing its best to outshine the stars above, as it guides sailors home to safe harbor.Desktop Version

Kagami-ike, Nagano, Japan — This serene Japanese landscape is reflected in the still waters of an artificial reservoir known as Kagami-ike, meaning ‘mirror pond." Surrounded by lush greenery and the Togakushi Mountain Range in Nagano Prefecture, Kagami-ike emerges from the morning mists to create an enchanting spectacle. During the cherry blossom season, visitors walk among sakura petals that float along the breeze while, in autumn, they can enjoy its surrounding orange and yellow foliage. This secluded spot is a wonderfully peaceful place for mindful meditation and self-reflection.Desktop Version

Birds of a feather — For World Migratory Bird Day, we"ve journeyed down to Bosque del Apache National Wildlife Refuge in southern New Mexico to join a group of sandhill cranes and their mallard duck friends as they feed in shallow water. Each year beginning in late October, this 57,000-acre refuge becomes the winter home to tens of thousands of migratory birds including sandhill cranes and various species of geese and ducks who travel from as far away as Alaska and Siberia to hunker down in warmer climes. They stay until late February when they begin their journey back north to their summer homes.Desktop Version

World Sea Turtle Day — Happy World Sea Turtle Day! Today people around the world gather to clean beaches and help animals like this hawksbill sea turtle thrive. The largest populations of hawksbill sea turtles are found in the Caribbean, Indian, and Indo-Pacific Oceans but you"ll find sea turtles in every ocean, except the Arctic and Antarctic.Desktop Version

Freeloaders of the avian world — Ever felt like some folks are just born jerks? Birds can relate. Take for example the uninvited speckly-white visitor to this robin"s nest: That smaller egg belongs to a baby cowbird whose mother sneakily laid it among the blue robin eggs when no one was looking. Once the baby birds all hatch, the cowbird will grow much faster and larger than its robin "siblings," soon becoming an only chick by muscling them right out of the nest. And if mama robin ejects the cowbird egg before it hatches, the cowbird mom may take notice and chuck the remaining robin eggs from the nest out of spite.Desktop Version

Christmas market at Belvedere Palace in Vienna — Christmas markets win the holiday trifecta: You can buy interesting, often handcrafted gifts, they are set in picturesque, romantic towns and villages in Europe, and they tempt you with mulled wine and local delicacies.

Guanahacabibes National Park, Cuba — Today we"re admiring red mangrove seedlings at Guanahacabibes National Park in Cuba. Mangrove forests not only protect coastlines but are a crucial component of tropical coastal ecosystems and are uniquely suited to thrive in brackish or salty water. These hardy trees can withstand the force of tremendous waves and ferocious winds, fending off the damaging effects of storms and erosion.Desktop Version
