Notes from an underground lake
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
When Death Valley blew its top
When Death Valley blew its top
Deep below Death Valley"s charred surface, blazing hot magma once gushed up through a geologic fault until it hit groundwater. The magma quickly turned the water to steam, and like a defective subterranean pressure cooker, the Earth"s crust blew its top in a ferocious explosion. The hydrovolcanic eruption sent up a mushroom cloud of steam and spewed burnt volcanic cinders for miles. It also left the giant crater seen in this photo and 12 smaller ones spread across the surface.Desktop Version
Snow buntings take flight
Snow buntings take flight
These snowflakes have feathers! The birds you see in this wintry image are snow buntings, sometimes referred to as "snowflakes" because of the distinct white in their wings. These medium-sized Arctic specialists love the cold and travel farther north than other passerine birds. Only ravens can be found north of snow buntings.Desktop Version
Class, please take out a No. 2 pencil…
Class, please take out a No. 2 pencil…
In some parts of the US, students have already returned to the classroom, while others are frantically squeezing the last drops of freedom from summer break as they prepare to start a new school year. One school supply that unites most students is the classic, yellow-coated, No. 2 pencil. For centuries, the pencil was a tool so vital that many would use theirs until only a tiny stub remained. An entire market for various pencil accoutrements existed in the 18th and 19th centuries, including a pencil grip called an ‘extender’ that allowed you to use the last bit of a pencil so as not to waste what was, at the time, a precious commodity. Think of it in terms of all the things you buy to enhance your mobile phone or tablet, and then imagine that the pencil once held equal value as a communication device. (In our hearts, it still does.)Desktop Version
Harvest time in the Palouse
Harvest time in the Palouse
The Palouse region of the inland Pacific Northwest is an unusually hilly prairie that straddles the state line between Washington and Idaho. Farming seems an unlikely endeavor here, but the land, and the weather patterns, make it ideal for wheat and lentil farming. This time of year, the soft white wheat harvest is on, as the crop turns from green to gold, and for the farmers, from harvest to profit. Before Europeans and early US settlers arrived, the Palouse was occupied by the Nez Perce people, who bred and raised horses with spotted coats—a breed that would eventually come to be known as "appaloosas"—a gradual permutation of the name "Palouse."Desktop Version
Happy Birthday, Eiffel Tower
Happy Birthday, Eiffel Tower
Locally, it"s called "La dame de fer," which translates to English as "The Iron Lady." To the rest of the world, it"s the Eiffel Tower, a landmark nearly synonymous with all things Parisian. It"s one of the most recognizable structures in the world and the most visited monument with an entrance fee. The Eiffel Tower took 500 workers two years, two months, and five days to complete. Most of the structural work was finished by the end of March 1889 and to celebrate, the builders led a group of government officials and journalists to the top of the tower on March 31. It was, at the time, the highest man-made structure in the world. With the addition of a new radio antenna on March 15, 2022, the Eiffel Tower grew an additional 20 feet and is now 1,083 feet tall, just in time for its 133rd birthday.Desktop Version

Piazza IX Aprile, Taormina, Sicily, Italy
Welcome to Taormina, an historic Italian resort built into a hillside high above the Ionian Sea on the coast of Sicily. From here you can take in panoramic views of the coast of Calabria, on the Italian mainland, the city of Syracuse, and Mount Etna, roughly 20 miles away.Desktop Version
A shell of many colors
A shell of many colors
We could perhaps fool you and claim you"re viewing a long-lost Jackson Pollock canvas, but it was Mother Nature who painted this blackfoot paua (aka rainbow abalone) shell. And modern art it ain"t: Fossils from similar marine gastropods date back at least 65 million years.Desktop Version
World Population Day
World Population Day
The bustling city streets of Barcelona seem as good a place as any to mark World Population Day. More and more of us are heading to the city. It"s estimated that 2007 was the first year in which more people lived in cities than in rural areas. If current trends continue, by 2050 about two-thirds of the world population will be living in cities. City planners and government officials will need to account for this rapid increase as power grids, water supplies, public transit, and emergency services will all be stretched.Desktop Version
Instant romance
Instant romance
If you visit the Lost Angeles County Museum of Art, you’ll be able to walk through this art installation made from 202 street lights arranged in a tight grid. Over the course of about 20 years, artist Chris Burden collected 1920s- and ‘30s-era street lights, which he meticulously restored, painted, and installed in 2008 as ‘Urban Light’ at LACMA’s entrance. This year, for its 10-year anniversary, the 309 incandescent light bulbs of the sculpture were replaced with more efficient LED bulbs designed to emulate the soft light of the original bulbs and to reduce harmful emissions.Desktop Version
Chilling out in the Arctic
Chilling out in the Arctic
Surfers from Norway and around the world gather each September in Unstad, a tiny village in Norway"s Lofoten Islands, to compete in the Lofoten Masters, which bills itself as the world"s northernmost surfing competition. Described by some as home to the best surf break in Norway, the island village, where sheep easily outnumber villagers, boasts two surf shops to help both novices and experts prepare for the extreme conditions. And surfing isn"t just a summer sport at this famous beach located inside the Arctic Circle—during winter months, surfers come here for the unique experience of surfing under the aurora borealis.Desktop Version
Bear watching in the Finnish forest
Bear watching in the Finnish forest
If you go out to the woods today in parts of Finland, you might get a big surprise. That"s because about 2,000 brown bears can be found freely roaming the taiga—or boreal forest—which covers most of the country, making this rugged wilderness in northern Europe the perfect place to see these majestic animals in their natural habitat. And bear watching is a popular pastime in Finland. The bear-watching season begins in April—when the first bears emerge from hibernation in a white blanket of snow—and lasts until fall. Summer nights are the best time to spot the bears, even under the golden glow of the midnight sun for those who venture north of the Arctic Circle. Many observe the creatures from the safety of a "hide," a purpose-built wooden cabin offering visitors a close-up view of a real teddy bear"s picnic.Desktop Version
World Theatre Day
World Theatre Day
What better place to celebrate World Theatre Day than the ancient theater of Taormina, Sicily, an amphitheater built in the Hellenistic style of the Greeks in the third century BCE. The venue was later expanded by the Romans and is one of the signature sights in Taormina. And if you look in the upper-right corner of the photo, that"s Mount Etna giving a performance of its own, spewing a little ash and smoke.Desktop Version

Red Planet Day
Red Planet Day
About 140 million miles away from Earth, the most relatable planet in the solar system orbits the sun. Mars, popularly known as the Red Planet, is the fourth planet from the sun, after Mercury, Venus, and Earth. We know more about Mars than any other planet but our own. That knowledge has been gained over centuries and has grown exponentially in recent years with the successful landings on Mars of the Curiosity and Perseverance rovers in 2012 and 2021 respectively. Today we celebrate those and other accomplishments on Red Planet Day, which coincides with the launch of Mariner 4, the first probe sent to Mars, on this day in 1964.Desktop Version
Big wheels on a big mountain
Big wheels on a big mountain
Today we"re high in the French Pyrenees at the Col d"Aubisque, a beautiful mountain pass topping out at 5,607 feet above sea level. The Col d"Aubisque is one of the legendary climbs of the Tour de France, which starts today in Nice. The grueling bicycle race lasts 23 days (21 days of racing), with riders clocking around 2,200 miles overall, and this mountain pass is often one of its most challenging stages. The road up the pass has grades in either direction that can tilt past 10%. This epic mountain stage was first added to the 1910 race and it"s since appeared in more than half the annual Tours, though not this year as it happens.Desktop Version

We"re looking at the rooftop of Casa Batlló, a six-story building in the center of Barcelona topped with colorful "scales." What brings us here? Well, here in the Catalonia region of Spain, and in several other locales from England to Ethiopia, it"s the feast of Saint George. You know George (or Jordi, as the Catalans call him): He"s the knight who, legend holds, saved a much-loved princess by defeating a fierce dragon. It"s said the tower jutting from the casa"s tiled roof represents George"s lance thrust into the monster"s scaly back.Desktop Version
Earth at Perihelion
Earth at Perihelion
We"ve reached perihelion! Two weeks after winter solstice the Earth"s orbit is closer to the sun than at any other time of year—a result of the Earth"s elliptical orbit. You may think, "If we"re so close to the sun, why can"t I feel the heat?" Well, that"s because we"re only receiving about 7% more solar energy than normal, which doesn"t really have much impact on the weather.Desktop Version
Indigenous living
Indigenous living
Just north of Ketchikan, Alaska, is Totem Bight State Historical Park, a 33-acre space dedicated to preserving elements of the Indigenous Haida and Tlingit cultures of this area. Visitors can walk through the low door of the Clan House to see how families from the tribes once lived. The park also boasts a collection of 14 traditionally crafted totem poles based on 19th-century originals. The order and positions of the symbolic faces on the poles show the progression of a specific story that can be interpreted by those who know how to "read" the carvings.Desktop Version
International Day of Human Space Flight
International Day of Human Space Flight
Sixty-one years ago today, Yuri Gagarin became the first human to see Earth from space, with a view likely similar to this image of the waning gibbous moon taken from the International Space Station. With a call of "Poyekhali!" ("Off we go!"), Gagarin launched into low Earth orbit in his Vostok 3KA spacecraft, making history in less than two hours with a complete trip around the planet. Landing in rural Russia, he became an instant worldwide celebrity—that is, after convincing puzzled locals he was a comrade and not a space alien.Desktop Version

Get on your bike and ride
In honor of the UN"s World Bicycle Day, we"re at Triglav National Park in Slovenia, with a bird"s-eye view of riders crossing this dubious-looking wooden suspension bridge over the blue glacial water of the river called Soča. Protecting some of the most magnificent mountain landscapes of the Julian Alps, Triglav is the country"s only national park, but it"s a stunner. Running along Slovenia"s northwestern border with Italy, Triglav was first protected as a "conservation park" in 1924, then made a national park in 1981. The park gets its name from the mountain at its heart, Triglav, long considered a symbol of Slovenia and of Slovene identity.Desktop Version

Fight for your lefts
It"s International Left-Handers Day, so why are we showing this horned ghost crab whose right claw is noticeably larger than its left? Well, we"re calling this crab a lefty because while its beefy right pincher is useful for grappling with other crabs, it uses its left claw for precision work like bringing food to its mouth, as a human southpaw does. (Though to be fair, it"s never been observed which claw these crabs use for writing or playing golf.)Desktop Version

Today we"re in Assam, India, to celebrate International Tiger Day, the annual celebration of the magnificent striped cats that have captured our imagination through the ages.

Women s History Month
Women s History Month
To celebrate the start of Women"s History Month, our homepage photo features a candid shot of members of the US Army Nurse Corps in 1944. The women are shown in between training exercises while they await deployment to the South Pacific near the end of World War II. At the time, all who served in the Army Nurse Corps were women, and the units were all segregated. And though the need for nurses was urgent, the army had set a quota for just 160 Black nurses. By the end of the war, that number had increased to nearly 500.Desktop Version

Honoring some real heroes of World War II
In this photograph, likely taken in 1941, we see a group of cadets examining a map with their training instructor. They are (from left to right) Lieutenant John Daniels of Chicago, Cadet Clayborne Lockett of Los Angeles, Cadet Lawrence O"Clark of Chicago, Cadet William Melton of Los Angeles, and civilian instructor Milton Crenshaw of Little Rock. The pilots would later be known as the "Tuskegee Airmen," the first Black military aviators in the US Army Air Corps, a precursor of the US Air Force. During World War II, more than 1,000 Tuskegee pilots flew more than 15,000 individual sorties in Europe and North Africa, quickly becoming revered for their bravery and excellence.Desktop Version
