Saguaro cacti, Ironwood Forest National Monument, Arizona
Saguaro cacti, Ironwood Forest National Monument, Arizona
Massive succulents against a mountainous backdrop, underneath the sun-kissed Arizona sky—it"s prickly perfection. Pictured here are saguaro (pronounced "sah-wah-roh") cacti at the Ironwood Forest National Monument in the Sonoran Desert. Even if you haven"t seen one in person, when you hear the word cactus, you"re probably thinking of saguaro—tall, green, cylindrical, with arms pointing upward. From tattoos to coffee cups, you"ll find this iconic symbol of Arizona on almost everything. Though they are slow growers, these plants have been known to live over 200 years and reach enormous heights, with a 78-footer setting the record. Another cactus, known as "Grandaddy," survived in the sweltering desert for about 300 years, eventually succumbing to old age in the early 1990s. Cacti may not be for everyone, but they tend to grow on you (figuratively, of course)!Desktop Version

The Wave at Coyote Buttes
The Wave at Coyote Buttes
By showing you this coveted sight, we"re saving you a bit of an ordeal. To get a close-up view of the Wave, a whorled sandstone formation in the northern Arizona wilderness, you"d have to navigate a rugged and mostly trail-free hiking route in typically scorching temperatures. You"d also need to have a permit in your pocket. To protect the landscape, only a small number of permits are available, offered through a daily lottery. But maybe for you the journey is at least as important as the destination? If so, this is just one hike of many in the expansive Paria Canyon-Vermilion Cliffs National Monument, which protects more than 100,000 acres of Arizona and Utah canyonland.Desktop Version
Squirrel Appreciation Day
Squirrel Appreciation Day
What"s that long, bushy tail scurrying across the branches? Chances are, it"s a squirrel. These little rodents are found across most of the globe, and today is their special day: Squirrel Appreciation Day. This unofficial holiday was started by a North Carolina wildlife rehabilitator to encourage people to leave out seeds and nuts for these critters. From the tiny least pygmy squirrel—just 5.5 inches long—to the Bhutan giant flying squirrel at more than 4 feet, these mammals come in all shapes and sizes.Desktop Version
Leap day
Leap day
Are you a "leapling"? No, not like this Eurasian red squirrel; rather, that"s the term for anyone born on leap day. A leap year is a calendar oddity that exists because Earth"s orbit and our usual year count are slightly out of sync. Earth takes 365.25 days to revolve around the sun. To compensate for those extra 5 hours, February gets an extra day—leap day—every four years. The concept, dating back to the ancient Romans, was refined in the Gregorian calendar, introduced in 1582 by Pope Gregory XIII. While the purpose of the day is to keep our year aligned with the solar calendar, it can also serve as an extra day to prepare for spring! Cultures worldwide mark leap days and years with unique customs. In Ireland and Britain, women propose to men, in Greece, marrying during a leap year is said to bring misfortune, and in France, a satirical newspaper is published.Desktop Version
Capitol Reef National Park, Utah
Capitol Reef National Park, Utah
Carved by time, wind, and water, Capitol Reef National Park showcases rust-hued cliffs and the natural beauty of the American West. The park was named after a series of Navajo sandstone domes said to resemble the US Capitol Building and the Waterpocket Fold, a huge ridge in the Earth"s crust, which was referred to as a reef by prospectors. This 100-mile-long monocline—a step-like fold—is thought to have formed around 50 to 70 million years ago, and is home to towering cliffs, narrow canyons, and colorful rock formations. Capitol Reef was established as a national monument in 1937 and was designated a national park on December 18, 1971.Desktop Version
World Reef Day
World Reef Day
Marovo Lagoon in the Solomon Islands is the largest saltwater lagoon in the world. Protected by a double barrier reef, it"s home to unique marine life and coral, making it a bucket-list destination for divers. The beauty and diversity of species contained within its pristine 270 square miles are the perfect inspiration for World Reef Day, observed every year on June 1 to bring awareness to this vital but largely unseen part of our natural world. Reef Day also kicks off World Oceans Month, a time to celebrate and learn more about these indispensable ecosystems.Desktop Version
Museum Night in Berlin
Museum Night in Berlin
As the summer is fading away, we find ourselves reminiscing about vacations and long hours of lively evenings. But let"s not bury the picnic days just yet! There is plenty to look forward to, especially if you are in Berlin. The Long Night of Museums only happens once a year—on the last Saturday of August since 1997—but it shakes up Museum Island and the rest of the German capital. The event series is more than a peaceful appreciation of artifacts—quite the opposite—you can expect music, talks, workshops, cocktails, dance, and more from 6 PM into the small hours of the morning. Featured in today"s image, Museum Island—embraced by the Spree River—is listed as a UNESCO World Heritage Site, and it is home to a museum quintet: Altes, Bode, Pergamon, and Neues Museums, and Alte Nationalgalerie.Desktop Version

Pumpkin field, Victoria, British Columbia, Canada
As fall covers the landscape with amber hues and the chill of Halloween approaches, it"s time to start carving some spooky jack-o"-lanterns. Originally from Ireland and Scotland, this craft was brought to America by immigrants who initially made lanterns from turnips and potatoes but later found pumpkins more plentiful and easier to carve. Once hollowed out and lit with candles, the gourds were transformed into flickering defenses against evil spirits.Desktop Version
Squirrel Appreciation Day
Squirrel Appreciation Day
Have you ever been captivated by a squirrel crossing your path? January 21 is Squirrel Awareness Day, honoring these furry seed distributors. Today"s homepage star is the Eurasian red squirrel, whose striking reddish-brown coat, white underbelly, and bushy tail are a familiar sight in several countries. These squirrels are not only exceptional jumpers—capable of leaping up to 6 feet in one jump—they can even swim to search for food. They gather nuts and acorns in the autumn and hide them, to see them through the winter months. If you spot fuzzy-tailed squirrels frolicking in your backyard, they might also appreciate a feeding station stocked with treats such as raspberries or crab apples.Desktop Version
Château de Villandry, France
Château de Villandry, France
The Château de Villandry in France is renowned for its exquisite gardens that are considered a masterpiece of Renaissance horticulture. The gardens, which are divided into sections, feature geometric patterns, vibrant flowerbeds, serene water elements, and meticulously trimmed hedges. Each section has its own theme, ranging from ornamental to practical, and is bursting with a stunning blend of colors and textures. The château"s gardens showcase the harmonious relationship between architecture and nature. Stunning gardens have surrounded the château since it was built in 1532, but their appearance changed drastically over the centuries. After Joachim Carvallo acquired the estate, he spent 10 years from 1918 reinventing and restoring the Renaissance formal gardens. Other elements have been added in the decades since and the gardens continue to captivate visitors to this day.Desktop Version

Molokini Crater, Maui, Hawaii
Today we"re at Molokini Crater. This pleasant crescent in the Pacific Ocean lies in the "Alalākeiki Channel between the Hawaiian islands of Maui and Kaho"olawe. The islet is all that remains of a volcano that erupted about 230,000 years ago. According to Hawaiian mythology, Pele the fire goddess was in love with a man named Mo"o.

50 years of the Endangered Species Act
50 years of the Endangered Species Act
Today is a special milestone for our furry, scaly, and feathered friends: the Endangered Species Act is turning 50. This landmark legislation, signed into law in 1973, has been helping species on the brink for half a century. Who"s that in the spotlight? A humpback whale! Known for their haunting songs and acrobatic breaches, these gentle giants are a success story of the ESA. They were once on the edge of extinction, largely due to commercial whaling, but thanks to conservation efforts, their population has bounced back from around 5,000 in 1966 to an estimated 135,000 today. However, our work isn"t over. Challenges persist, from habitat loss to poaching. So, what can we do? Spread the word, support conservation efforts, participate in local initiatives, and be eco-friendly.Desktop Version

Serra de Tramuntana, Majorca, Spain
Serra de Tramuntana, Majorca, Spain
They"ve been growing olives on the Spanish island of Majorca in the western Mediterranean for more than 2,000 years. Early settlers, the Phoenicians and Greeks, introduced the first olive trees but the groves in the Serra de Tramuntana range expanded during Spain"s Islamic era, between 709 and 1492. Olive oil became a crucial ingredient in culinary traditions on Majorca, the largest of the Balearic Islands. One ancient tree on the island, Can Det, is estimated to be more than 1,100 years old, and is still producing olives.Desktop Version

Grand Canyon National Park turns 105
Happy birthday to Grand Canyon National Park! It"s been 105 years since this Arizona landmark was designated a national park by President Woodrow Wilson in 1919. The origins of this exceptional landscape, carved by the Colorado River, wind, and landslides, date back up to 6 million years.

Bald cypress trees in Georgia
Fall foliage is the hallmark of autumn, when thoughts turn to flannel and corduroy, pumpkin spice and s"mores. Sunny days and crisp nights invite us to step outside to enjoy the changing colors of the leaves. While some may consider the maples of New England the leaf-peeping gold standard, others would give the prize to the aspens of the Rocky Mountains or the cypress trees of the South.Desktop Version
Flower of Life symbol drawn in snow
Flower of Life symbol drawn in snow
German artist Michael Uy created this "Flower of Life" geometric pattern in the snow in Brandenburg. Preparations began about a week before the snow"s arrival, when Uy hammered 19 wooden posts into a field, carefully measuring the space between each post. After the snowfall, he walked near-perfect circles around all 19 pillars, using a string to keep an equal distance from the posts. The artist then used a broom to further remove the snow from his footprints and reveal the lines of the flower nearly 200 feet across. Uy"s piece was fully visible only when the sun was low. And only until the next snow or warm day. Luckily, a drone was dispatched to snap this photograph.Desktop Version
