Eye of the cave
Eye of the cave
Many sea caves and rock formations line the alluring Algarve coast in the south of Portugal, and today we"re shedding light on Benagil Cave—one of the region"s most spectacular and famous natural landmarks. Just east of the small fishing village of Benagil, the cave was formed about 20 million years ago from the pounding waves that sweep in from the Atlantic. Rainfall has caused the softer segments of limestone to erode, creating a giant hole in the cave"s roof, which is what we"re looking down through in our photo.Desktop Version
Punakaiki on South Island, New Zealand
Punakaiki on South Island, New Zealand
This portion of New Zealand"s South Island coast features plenty of strange geology. The Pancake Rocks, so named due to the stacked, flat layers of sediment and stone, were once underwater. As the Tasman Sea receded, the unusual rocks became the Punakaiki region"s shore. Erosion created openings along the cliffs called "blowholes." When the tide comes crashing in, water sprays up through the openings, and if you"re standing too close, you"ll get soaked.Desktop Version
Castle Frankenstein in Darmstadt, Germany
Castle Frankenstein in Darmstadt, Germany
To celebrate Frankenstein Day, aka the birthday of writer Mary Shelley, we bring you this moody photo of Frankenstein Castle at Darmstadt, Germany. A man named Johann Dippel lived here once, and is said to have been involved in attempts to reanimate body parts of the deceased. Sound familiar? That may be because Dippel’s life is thought to have influenced the creation of the novel ‘Frankenstein’ by Mary Shelley. While scholars debate the real-life inspirations, we do know that Shelley was just 19 when she crafted the story, essentially written on a dare made by poet Lord Byron. While spending a rainy summer on Lake Geneva in Switzerland, Shelley (nee Godwin), her future husband Percy Bysshe Shelley, and Byron, all decided to try writing ghost stories. Mary Shelley outdid them all by creating the well-known story of the mad doctor who brings the dead back to life. Her book is often cited as the first true work of science fiction.Desktop Version

NASA’s solar-powered Juno probe took this photo of a massive storm near Jupiter’s north pole. Juno’s been collecting data and taking incredible photos of Jupiter since 2016, showing us detailed evidence of the turbulent atmosphere surrounding the largest planet in our solar system.Desktop Version
Juniper Springs, Florida
Juniper Springs, Florida
Yes, the water here is as inviting as it looks: clear as glass, the shade of a precious gem, and a perfect 73 degrees every day of the year. Set within a subtropical forest, Juniper Springs is one of Florida"s oldest and best-known recreation areas, established in the 1930s as a place to camp, hike, and swim. Long before Disney arrived, natural springs like this one were the big draw in the Sunshine State.Desktop Version

Hocking Hills State Park, for National Public Lands Day. Hocking Hills is a 2,356-acre park in southern Ohio offering over 25 miles of hiking trails that pass by unusual rock formations, recess caves, and stunning waterfalls. This is Upper Falls, at one of the park"s most popular hiking destinations, Old Man"s Cave. This huge recess cave, as the legend goes, was named for a hermit who lived here in the 1800s. Then there"s Devil"s Bathtub, Conkle"s Hollow, and Rock House—sites worthy of a visit for their names alone, though the scenery won"t disappoint.Desktop Version
Happy anniversary to the National Park Service!
Happy anniversary to the National Park Service!
On the National Park Service"s Founders Day, we"re here on the North Rim of Grand Canyon National Park in Arizona peering out at the stunning vista. Can you see the rectangular hole in the canyon wall near the top of the image? That"s Angels Window. Brave hikers can make their way up to the trail above it, but the window itself is best viewed from various points along the North Rim. Far down below is the Colorado River. Beginning about 6 million years ago, it gradually carved downward through countless layers of sedimentary, igneous, and metamorphic rock. The Colorado and its tributary streams continue to deepen and widen the Grand Canyon even today.Desktop Version
Happy 800th, Salisbury Cathedral
Happy 800th, Salisbury Cathedral
We"re in the English county of Wiltshire to celebrate the 800th anniversary of Salisbury Cathedral—the towering marvel of Early English Gothic design rising behind these contentedly grazing sheep. The massive church"s first foundation stones were laid here in Salisbury—then called New Sarum—on April 28, 1220. The structure itself dates back even further, the bulk of it having been moved over a mile piece by piece from the former Roman stronghold of Old Sarum.Desktop Version
A red knot on the Shetland Islands, Scotland
A red knot on the Shetland Islands, Scotland
This little bird with its 20-inch wingspan weighs about as much as a stick of butter, but it has the stamina of an Olympian. Each fall, red knots are known to fly more than 9,000 miles from the Arctic to South America–and in the spring, they do the journey in reverse, for a roundtrip of more than 20,000 miles. The most famous red knot, known as ‘Moonbird,’ is so named because the total of its known migrations have exceeded the distance to the moon. Moonbird was first banded in Rio Grande, Argentina, in 1995 and has been sighted many times in the years after–amazing scientists and birders alike.Desktop Version

Hut, hut, hike!
Meerkats, also called suricates, are highly social animals that enjoy playing together and grooming each other. Members of the mongoose family, they live in mobs (yes, that"s what a group of meerkats is called) of 20 to 50 individuals that work together and share underground burrows to stay cool in the African heat.Desktop Version
Playa del Amor, Marietas Islands, Mexico
Playa del Amor, Marietas Islands, Mexico
This gorgeous shot was taken at Playa del Amor—aka Hidden Beach—a remote destination off the coast of Puerto Vallarta, Mexico, known for its pristine beauty. To get to it, visitors need to take a boat toward the mouth of Banderas Bay at the base of the Marietas Islands. Once there, they swim through a tunnel at low tide to reach the beach. The walls hide a sandy cove, where the turquoise waters contrast with flora-laden cliffs that perfectly frame the blue sky overhead. Playa del Amor (Lovers" Beach) is popular among tourists, but the number of visitors is limited to preserve its natural beauty and ecosystem.Desktop Version
Merry and bright
Merry and bright
Germans began decorating Christmas trees with candles as far back as the 1700s, but people wouldn"t begin stringing trees with electric lights until the late 1800s. Thomas Edison created the first practical incandescent lights and used them to decorate his Menlo Park laboratory for Christmas in 1880. Then three years later, the vice president of Edison"s company, Edward H. Johnson, had Christmas tree bulbs especially made, which he used to decorate the tree in his New York City home. Nevertheless, electric lights didn’t catch on as a holiday decoration among the general public until 1895, when President Grover Cleveland asked that the White House Christmas tree be illuminated by hundreds of multicolored electric bulbs.Desktop Version

Native American Heritage Month
Native American Heritage Month
Here in the Volcanic Tablelands near Bishop, California, is Sky Rock, a set of ancient petroglyphs that face the heavens. The volcanic rock formations of this area have made it a premier rock-climbing destination. But long before sport climbers flocked here, it was (and still is) home to the Paiute-Shoshone peoples, who are thought to have created these petroglyphs and many others throughout the tablelands.Desktop Version

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

Why you should thank a nurse today
Why you should thank a nurse today
Artist Tristan Eaton created this mural, "Now & Forever," as part of a big thank you to nurses and other medical personnel during National Nurses Week last year in New York City. At the time, the city was the epicenter of the coronavirus pandemic, and an army of nurses, doctors, and other hospital staff delivered critical care under dire conditions. Now a year later, nurses continue their vital work of providing care for the residents of New York and everywhere else. National Nurses Week is observed annually from May 6-12 to honor the crucial role that nurses play in health care—as if we needed any reminder of that after the year we"ve had. Still, we invite everyone to thank a nurse this week for their skill, professionalism, grit, and warmth. Our debt to them is deep.Desktop Version
Happy Bee Day to you
Happy Bee Day to you
If flowers are the starring cast of nature"s big spring show, then bees are the crew. Honey bees are always buzzing in the background, pollinating not only our photogenic petaled friends, but also food crops that make up a third of humans" diet. But when seen in front of the camera, they"re hardly bee-listers: Today"s pollen-coated photo subject was certainly ready for her close-up.Desktop Version
A courtyard scene from Spain
A courtyard scene from Spain
For centuries people have lavishly decorated the courtyards of Córdoba, in southern Spain"s Andalusia region. Here in the San Basilio neighborhood of the city’s old town, the densely packed whitewashed houses look out onto courtyards and patios embellished by hanging flowerpots and trailing plants. The sculpture on today’s homepage, by artist José Manuel Belmonte, pays homage to the caretakers who pass along the tradition.Desktop Version
Mont-Saint-Michel
Mont-Saint-Michel
Rising majestically out of the bay, Mont-Saint-Michel is once again a true island, at least during high tides. A crude, elevated causeway built in the 19th century once connected Mont-Saint-Michel to the mainland, allowing visitors to walk across to the spectacular rock. But in 2014, the causeway was removed and replaced by an elegant, curving bridge above the tidal flats. Now water flows freely around the monument at high tide, making the tiny island fortress a real island for the first time in more than a century.Desktop Version

Birds of the Drömling
Common cranes (aka Eurasian cranes) often gravitate to wet open fields, bogs, and marshes. This flock is congregating in the Drömling wetland in Germany. The most widely distributed of all the 15 species of cranes, its native range covers a wide swath of Europe and Asia, with the largest breeding populations in Russia and Scandinavia. As winter approaches, common cranes make the long journey south, often in large flocks of about 400 birds, to North Africa or parts of southern Europe and Asia in search of more civilized temperatures.Desktop Version
Kjell Henriksen Observatory
Kjell Henriksen Observatory
While these domes look like they should be in a movie set depicting a galaxy far, far away, they"re actually part of a scientific research station here on planet Earth. Kjell Henriksen Observatory is named for a Norwegian scientist whose research focused on the polar lights. The aurora borealis is frequently seen here, deep within the Arctic Circle in Norway"s remote Svalbard territory. And the observatory is specially designed to observe the aurora. Since it opened in 2008, the observatory has become a destination for atmospheric scientists, who can rent one of these 30 glass-topped rooms built to house high-end optical instruments.Desktop Version
An improbable tribute for Towel Day
An improbable tribute for Towel Day
"Space," Douglas Adams observed in his comic sci-fi novel "The Hitchhiker"s Guide to the Galaxy," "is big. Really big. You just won"t believe how vastly hugely mind-bogglingly big it is. I mean, you might think it"s a long way down the road to the chemist, but that"s just peanuts to space." So, in his fictional universe, Adams invented the Infinite Improbability Drive as a way to cross its vast distances in a nothingth of a second. And, in one memorable passage, to convert two approaching nuclear missiles into a bowl of petunias and a sperm whale. Thus, today"s image of the Earth"s largest toothed whale is our tribute to Adams on the 20th annual celebration of Towel Day (it"s surprisingly difficult to find a really great image of a bowl of petunias).Desktop Version
Celebrating Flag Day
Celebrating Flag Day
June 14 is Flag Day, which commemorates the adoption of the flag of the United States in 1777. Our nation"s first official flag had 13 stars and 13 red and white stripes to represent the original 13 colonies that broke from British rule. The stars were arranged on a blue background to represent a "new constellation." In 1795, two more stars and two stripes were added to reflect the entry of Vermont and Kentucky to the Union. Then in 1818, Congress passed a plan to go back to 13 stripes and add only stars for new states. The current version of the flag has been in effect since 1960, after Hawaii became a state the prior year. The flags we"re looking at here are flying in New Jersey"s Liberty State Park, with the Statue of Liberty in the background.Desktop Version
