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

Fannette Island, Lake Tahoe — Tucked into a tiny bay of a grand alpine lake is this granite bump called Fannette Island, the only island in Lake Tahoe. The massive lake lies in the Sierra Nevada at an altitude of 6,225 feet, straddling the state line between California to the west and Nevada to the east with near perfect symmetry. Fannette Island is in Emerald Bay, on the California side of Tahoe"s southwest shore. A narrow inlet, seen here at the top center of this image, connects Emerald Bay to the rest of the lake, whose natural beauty draws visitors in all seasons of the year.Desktop Version

World Space Week — Since the first pictures arrived from the James Webb Space Telescope this July, the world has been mesmerized by the vividness, resolution, and literally otherworldly nature of the telescope"s infrared images. The JWST"s technology will revolutionize the fields of astronomy and cosmology, allowing observation of the first stars in the universe and the formation of the first galaxies. The telescope"s high infrared resolution and sensitivity may even allow it to reveal potentially habitable exoplanets.Desktop Version

Paleontology meets art — Though it looks like a fresco from ancient Greece, this is the fossilized remains of a fern found in Córdoba, Spain. The fossil dates back to the Carboniferous period, roughly 350 million years ago. This is a "compression fossil"—where a small amount of the original plant material was retained with the mineral deposits that helped form the impression. Why all the paleobotany talk? It"s National Fossil Day, and we’re excited! Whether you make a trip to your local natural history museum, trek off to a national park with a fossil exhibit, or just look at fossil photos on the web, we hope you find a fun way to celebrate National Fossil Day.Desktop Version

Poinsettia Day — During the holiday season, poinsettias brighten up homes in suitably festive coloring, serving as symbols of goodwill. December 12 marks National Poinsettia Day, a special occasion to celebrate this holiday favorite. The plant was introduced to the US by Joel Roberts Poinsett, a botanist and former minister to Mexico who died on this day in 1851. Poinsettias can be found growing in the wild from Mexico to Guatemala. The ancestors of the modern, commercially available version have been traced to the Mexican state of Guerrero. The crimson-leaved plant was used by the Aztecs as a red dye and as a fever-reducing medicine.Desktop Version

Balloon Ascension Day — Up, up, and away! Today is Balloon Ascension Day, celebrating the anniversary of the first manned balloon flight in North America. French aeronaut Jean-Pierre Blanchard"s flight took him from Philadelphia to Deptford, New Jersey, back in 1793. Interest in ballooning took off from there and today, hot air balloon festivals take place across the country, including Albuquerque, where today"s sunrise image was taken. Every year, hundreds of thousands of people attend the nine-day Albuquerque International Balloon Fiesta—the largest hot air balloon festival in the world—to see skilled pilots expertly maneuver their baskets through balloon-filled skies.Desktop Version

Notes from an underground lake — The Ruskeala Mountain Park is an eerily beautiful reminder of the booming mining industry that thrived for centuries in this area of Russia near the border with Finland. Located on the site of an abandoned marble quarry, the park opened to the public in 2005. The centuries-old quarry has been flooded with groundwater since the end of World War II, although some old buildings and kilns from the mines are still intact.Desktop Version

It s aboat time for the Barcolana — Today we"re featuring an image of the Barcolana regatta, which is happening this weekend off the shore of Trieste, Italy. What makes this race so unusual—and so popular—is that it"s open to both professional and amateur sailors. Its beginning was fairly inauspicious—in 1969 only 51 boats sailed in the inaugural race. But it"s been drawing increasing numbers of sailors and spectators to Trieste each year. Last year, for the 50th anniversary of the Barcolana, 2,689 yachts raced the course and set the official record for largest sailing race in the world. Featuring a youth sailing race, an open-water swimming race, a night sailing race, music concerts, food and wine tastings, and many other events, the Barcolana offers opportunities for landlubbers and sea dogs alike to enjoy themselves during the regatta.Desktop Version

Christmas Eve — This isolated cove on "the Last Frontier" is the least likely place you"d expect to find a Christmas tree decorated from head to toe with lights aglow. Amalga Harbor lies about 15 miles north of Juneau (one of the few coastal state capitals in the US) and shows that the public expression of Christmas cheer knows few limitations–and may include use of a small barge. This photograph was taken from nearby Ernest Gruening State Historical Park, which was named for the former governor of the Alaska Territory. Gruening led the territory from 1939 to 1953 before becoming one of the state"s first US senators when Alaska became a state in 1959. After his political career ended, he and his wife lived in a cabin that was preserved as part of this historic site.Desktop Version

The lemurs of Madagascar — What better place to ring in World Lemur Day than Madagascar? The island, about the size of Texas off the coast of southeastern Africa, is the native home to lemurs. Today you"ll find over 100 species and subspecies of the critters here. Most are small, with a pointed nose, large eyes, and a tail. They mainly live in trees and can be highly social, like the ring-tailed lemurs on our homepage, or live a solo existence like the elusive aye-aye. Lemurs have opposable thumbs and five fingers with fingernails on each hand, characteristics that help secure their spot as members of the primate order of mammals. About 65 million years ago, scientists believe, lemurs drifted on rafts of vegetation from the African continent to the shores of Madagascar. Safe from competition and most predators, lemurs evolved into many highly specialized varieties and now can be found in almost all habitats on the island.Desktop Version

An icy extravaganza — We’re just outside Brainerd, Minnesota, for the Ice Fishing Extravaganza on Gull Lake. Each year in late January, more than 10,000 people will come out to catch as many fish as they can—mostly walleye and northern pike, but all fish species are eligible. The contest is organized and run by volunteers exclusively, and 100 percent of the proceeds—around $150,000—goes to local charities.Desktop Version

Laguna de Torrevieja, Spain — When we encounter bodies of water in nature, we might expect hues of blue, from the pale cyan shade of lagoons to the navy blue of deep lakes. But pink water—where on Earth could that be found? At (deep breath) El Parque Natural de Las Lagunas de La Mata y Torrevieja in Alicante, Spain. Here, there are two lakes: one green and one pink, and it is the latter that you see on our homepage. The highly saline water, dotted with clusters of salt crystals, is the perfect environment for microscopic algae, which are rich in carotenes. This results in the rosy tinge that protects the algae from solar radiation. And the pink is just getting started, as the algae are eaten by tiny crustaceans, which turn pink and are then eaten by flamingos, which acquire the rosy hue as well.Desktop Version

World Otter Day — Watching sea otters playing in the water is always a treat. But while they look cute, these furry critters are also the top predators in their food chain, "otterly" vital to keeping ecosystems in balance. Sea otters eat sea urchins and without them, sea urchins spread across the sea floor, destroying crucial kelp forests which provide food and shelter for many other aquatic animals. Unfortunately, sea otters are one of five otter species listed as endangered by the International Union for Conservation of Nature. Five others are listed as near-threatened and two as vulnerable. Of the 13 otter species worldwide, only the North American river otter’s population is considered to be stable. On the last Wednesday in May, World Otter Day seeks to raise awareness about the threats to otters, and how to protect them.Desktop Version

Bridge of Hillsborough County — The Hancock-Greenfield Bridge (aka County Bridge) has offered a picturesque passage over the Contoocook River in southern New Hampshire since 1937. It was built to replace another covered bridge that had been destroyed in a flood. But why even build a covered bridge? In a word, longevity. The roof and walls help protect the timber supports from rot. For comparison, an uncovered wooden bridge lasts an average of 20 years, while the covered variety can reach 100 years or more.Desktop Version

Arches National Park, Utah — This stunning structure is Delicate Arch, the most famous of 2,000 stone arches scattered around Arches National Park in Utah. It is made up of Entrada Sandstone, the grains of which once formed a massive desert. They were cemented together by minerals, forming sandstone riddled with tiny holes. Over millennia, the rain seeped in and slowly dissolved the rock from the inside, forming these eye-catching sculptures. Most of the arches in the national park are formed from Entrada Sandstone and were once buried by other rock layers. They won"t last forever, but over time, new shapes will emerge from the layers of rock below to replace them. Every year, close to 1.4 million people visit the park to see Delicate Arch and this slowly shifting landscape for themselves.Desktop Version

Swim city — Switzerland may be a landlocked country in the middle of Europe, but with about 6% of Europe"s fresh water flowing through its countless rivers and lakes, there are plenty of outdoor swimming spots to cool down in the Swiss summer heat. Today, we"re dipping our toes in the pristine waters of Lake Zürich in Switzerland"s largest city, which has developed its own urban lido culture. Dotted across Zürich, you"ll find lots of lidos (public open-air swimming pools or bathing beaches) that make the most of the city"s lakes. This time of year, it"s common to see bankers and other workers change from business suits into bathing suits as they enjoy a quick swim during their lunch break.Desktop Version

San Francisco’s City Hall illuminated by the iconic colors of Pride — We’re celebrating Pride weekend with a view onto a Beaux-Arts gem that has a prominent place in the history of gay rights and culture. Even the city of San Francisco itself has played an outsized role in fostering gay pride, community, and visibility. It’s a legacy that can be traced along the timeline of the city’s many firsts. The San Francisco Bay Area held one of the first Pride parades after the 1969 Stonewall riots in New York, the event that sparked the gay liberation movement and the modern fight for LGBTQI+ civil rights. This is just part of the heritage that will be celebrated at San Francisco’s Pride this weekend, where people will be marking the 50th anniversary of the Stonewall riots. A big parade is planned with vibrant displays that will decorate Market Street, continuing all the way to the Golden Gate City’s Civic Center.Desktop Version

Let’s have a ball — You know a game must be fun if it’s stuck around for eight centuries–and that’s how long folks have been playing lawn bowling (in some form or another). It was the invention of the lawn mower in 1830, allowing for smoothly cut bowling greens, that really popularized the sport. Our homepage features the balls called ‘woods,’ or ‘bowls,’ that competitors use during game play. The objective is to roll the grapefruit-sized balls toward a smaller ball called a ‘jack,’ and points are awarded to the players who come the closest. Fancy a game?Desktop Version

Wind horses carry wishes for a new year — For the first day of Losar, or the Tibetan New Year, we"re paying a visit to these Buddhist pilgrims at the Ganden Monastery in Lhasa, Tibet. Losar is celebrated for 15 days, but most events occur in the first three days. They include wishing family members a prosperous year, praying at monasteries or temples, exchanging gifts, burning incense, chanting, wrestling, horse racing, and more. Celebrations for the new year end with Chotrul Duchen, or the Butter Lamp Festival. The pilgrims in today"s image are releasing prayer flags called "wind horses" or lungtas, a ritual they perform for Losar and during the rest of the year as well. Upon releasing the prayer flags, the pilgrims ask the mountain deity to "increase their fortune like the galloping of a horse and expand their prosperity like the boiling over of milk."Desktop Version

Málaga, Spain — Today we"re visiting a city with over 2,800 years of history—it"s one of the oldest in Europe. Málaga is said to have been founded by the Phoenicians in 770 BCE and today its year-round exceptional weather has made it a center of tourism in Spain. Situated perfectly along the Costa Del Sol, this culturally rich mecca is visited by around 6 million tourists in an average year. If you can pull yourself away from the beautiful beaches, you"ll find yourself in a city abounding in historical architecture, museums, and restaurants featuring outstanding local seafood.Desktop Version

Rideau Canal Skateway in Ottawa, Canada — Today we"re at the iconic Rideau Canal Skateway in Canada"s capital city of Ottawa. Each winter a 4.8-mile section of the canal downtown is converted into the world"s largest—and second-longest—outdoor skating rink. Rideau was designated a UNESCO World Heritage Site in 2007, and most years this rink section becomes a featured attraction of Winterlude, a free annual festival that usually attracts visitors from across the country for the first three weekends of February.Desktop Version

Kirkjufell, Iceland — From glaciers and waterfalls to volcanoes and black sand beaches, Iceland"s Snæfellsnes peninsula has "GoT" it all. Pictured here is the 1,519-foot-high Kirkjufell, a hill often called "Church Mountain," as it is said to resemble a steeple. In fact, it is a nunatak, a rock formation that protrudes through an ice sheet or glacier. You might recognize it from the "Game of Thrones" series, where it featured in a scene set north of the colossal ice wall. When it"s not starring on TV, it is popular with photographers thanks to its unusual shape, coastal location, and colors that shift with the seasons. And if you"re lucky, and the weather conditions align, Kirkjufell offers a magnificent view of the northern lights.Desktop Version

Lunar eclipse — If you missed the first full lunar eclipse of the year back in May, you"ll get another chance tonight as the second blood moon (as lunar eclipses are often called) of 2022 takes to the sky over the Pacific region. Tonight"s display can be seen from Asia, Australia, North America, and parts of northern Europe and South America. If you"re lucky enough to find yourself under a clear sky, the view might look something like this image, taken over Mount Crested Butte, Colorado, during the lunar eclipse of September 27, 2015.Desktop Version

Dancing in The Nutcracker — If it"s December, then countless dance companies are likely performing "The Nutcracker." The ballet has become an iconic holiday entertainment staple, produced around the world. This photo captures a scene from the 2016 production by the English National Ballet at the London Coliseum. The company has been performing "The Nutcracker" during the Christmas season since 1950.Desktop Version

The Great Glen — Was this photo taken in a peppermint forest? This rare and delicate hoarfrost may look like a confectioner"s coating, but it"s just the ice that forms when the Scottish Highlands" fog mixes perfectly with a sharp cold snap.Desktop Version
