Rocks on the move
Rocks on the move
No, that stone in today"s homepage image didn"t get there by itself. Or did it? Not only is Death Valley one of the hottest places on Earth, it also boasts a mysterious geologic phenomenon—rocks that drift across the exceptionally flat desert floor, seemingly under their own power. The rocks here at Death Valley"s Racetrack Playa are known as "sailing stones" and they can vary in size from a few ounces to hundreds of pounds. As seen in our image, the stones leave long trails behind them as they move across the scenic dry lakebed.Desktop Version

Chicagohenge
During the fall and spring equinox, the celestial phenomenon known as Chicagohenge occurs when the sun rises or sets directly between the buildings lining Chicago"s east- and west-facing streets. The city"s almost perfectly aligned grid is responsible for the event.Desktop Version
Celebrating the Acadians
Celebrating the Acadians
In honor of Canada"s National Acadian Day, we"re on the shores of New Brunswick as the ocean recedes to reveal the Bay of Fundy"s massive intertidal zone. The tide is a big deal at the bay—more than five times bigger than in most places. Typical tides around the world have a range of 3 to 6 feet, but these waters drop as far as 50 feet from high to low tide.Desktop Version
Black History Month
Black History Month
To mark the beginning of Black History Month, we"re paying tribute to one of the few all-Black combat regiments in World War I, true heroes who were instrumental in achieving the Allied victory. The storied 369th Infantry Regiment, famously known as the Harlem Hellfighters, served in frontline trenches for 191 days—longer than any other American unit in the war—and suffered 1,500 casualties, the most losses of any American regiment. They fought under the 16th Division of the French army, because many white Americans refused to go into combat alongside Black soldiers.Desktop Version
Mount Hood, Oregon
Mount Hood, Oregon
Mount Hood graces Oregon"s skyline with a pointed, snow-capped peak. At nearly 11,250 feet high, this dormant stratovolcano is the tallest mountain in the state, drawing adventurers and nature aficionados alike. With 12 named glaciers and numerous snow fields, Mount Hood offers a wintry playground all year round. It also nurtures ancient forests and provides a haven for wildlife, including cougars and wolves. Over the past 1,800 years, the volcano has erupted three times. While considered dormant, there is still a chance that it could erupt one day.Desktop Version
The borrowed days are here
The borrowed days are here
This photo of a European crested tit weathering a late-winter storm in Scotland may sum up the way some of us living in the Northern Hemisphere feel about the month of March. While the calendar tells us spring has arrived, the weather often seems to disagree. It"s the blustery, unpredictable elements of this time of year that inspired an old Western European folktale that the month of March "borrowed" three days from April so that it could indulge in a few final winter-like days. These "borrowed days" are the last three days of the month. Perhaps take comfort that it"s only three days. In some parts of Ireland, March borrowed nine days. That"s too many days.Desktop Version

Let s celebrate cephalopods
Let s celebrate cephalopods
For World Octopus Day, we"re lighting up your screen with a shot of a nocturnal octopus from the genus Callistoctopus in its larval stage. It was photographed on a night dive near the Big Island of Hawaii. You may not consider octopuses cute and cuddly, but they have charisma to burn. The highly intelligent species has been observed solving puzzles, unscrewing lids, and even using tools. One study recorded octopuses collecting discarded coconut shells and carrying them back to their dens to use as shelter. In another incident that made headlines, an octopus named Otto taunted staff at his aquarium by repeatedly crawling out of his tank to shoot water at the overhead lights, causing them to short-circuit. Octopuses aren"t all brains—they"ve got heart as well (three, in fact!). The more we learn about this species, the more impressed we are. Can"t every day be World Octopus Day?Desktop Version
Hitsujiyama Park, Saitama Prefecture, Japan
Hitsujiyama Park, Saitama Prefecture, Japan
Phlox subulata is known by many names. While some call it moss pink, others call it creeping phlox, flowering moss, or mountain phlox. No matter what name you know it by, you cannot deny the beauty and charm of these tiny perennial flowers. They bloom in spring and add bright splashes of color wherever they grow.Desktop Version
Looking back on 150 years of rail travel
Looking back on 150 years of rail travel
In 1986, work began to convert an old rail yard in Scranton, Pennsylvania, from a relic to a heritage preservation site now known as Steamtown. A donated collection of train engines, some dating back to the 1800s, gave Steamtown exhibits to show off, while the fully functional rail yard provides a live demonstration of how trains work—and how rail transit greatly changed the United States.Desktop Version
Happy Father s Day
Happy Father s Day
These bald eagles look like they"re enjoying some family time on Father"s Day. But today is extra special for them, because it"s also American Eagle Day, a celebration that commemorates the date in 1782 when the bird was added to the Great Seal of the United States, effectively becoming a national symbol. With an olive branch in its right talons and a bundle of 13 arrows in its left (representing the 13 original states in the Union), the eagle is said to represent a strong desire for peace, but readiness for conflict. You"ll recognize the Great Seal of the United States from its appearance on passports, flags, official documents, and American currency.Desktop Version

What"s the best thing to do when you come face-to-face with a giant manta ray? Take a photo of course, and then share your creation with the rest of the world, especially on World Photography Day, celebrated each August 19. As this photographer can attest, a lot of work goes into taking a great photo. There"s more to it than having mastery of your equipment and a willingness to go on the hunt for the perfect shot. You also must be ready for a magic moment like this one, so when that amazing shot does present itself, you"re ready to capture it.Desktop Version
Glacier cave in Iceland
Glacier cave in Iceland
The Land of Fire and Ice is home to countless natural wonders, like this brilliant blue cave formed within the ice of a glacier. (Glacier caves are often called ice caves, but the term "ice cave" is properly used to describe a bedrock cave that contains year-round ice; a glacier cave is formed entirely within the ice of a glacier.) The majority of Iceland"s glacier caves are in Vatnajökull glacier, which covers about 8% of the island nation and is one of the largest glaciers in Europe.Desktop Version

If you"re already in the air looking down at this bird"s-eye view of Sky Harbor International Airport in Phoenix (or some other airport), well then, congrats. You"ve made it through the terminal on one of the busiest travel days of the year. Wait a second, isn"t the day before Thanksgiving the absolute busiest day to travel? Well, according to travel industry experts, traffic is actually heaviest on Fridays during the lazy, hazy days of summer. That"s when crowds of people clog the highways and skyways to get out of their respective towns and go on vacation. You, on the other hand, can relax. Unless your plans are to host a table full of hungry guests on Thanksgiving. In which case, may we suggest yoga and meditation tonight? (And turn off this electronic device before the flight attendant comes by again.)Desktop Version
Is that a buzzing sound?
Is that a buzzing sound?
Why are dozens of colorful boxes stacked in this field? To provide homes inside their walls for millions of honey bees, those hardworking pollinators, producers of honey, and tormenters of Winnie-the-Pooh. Wild honey bee colonies build their nests in trees and caves, but manmade boxes also do the trick, and humans have been building their own beehives since antiquity. The modern beehive boxes shown here contain frames to hold honeycombs that bees produce to store their honey, pollen, and young. When the bees have produced plenty of honey, the beekeeper can simply remove the frames to extract some of it, leaving the rest to nourish the hive.Desktop Version
Let’s go mothing
Let’s go mothing
In the Lepidoptera order of the animal kingdom, it’s butterflies who get all the glory. But we’d argue it’s their relatives, moths, that have the better story. With more than 160,000 species of moths around the world, moths outnumber butterfly species roughly 10 to 1. While most are nocturnal, the hummingbird hawk-moth on our homepage today breaks the mold. Found throughout Africa, Asia, and Europe, it’s shown here in the daylight of southern Sardinia, sipping nectar with its straw-like appendage known as a proboscis. Like a hummingbird, the moth makes a soft buzzing sound as it hovers over the flowers whose nectar it feeds on exclusively.Desktop Version

It"s Grandparents Day in the USA! Did you know Asian elephants live an average of 60 years in the wild? That means this pair of pachyderms in West Bengal, India, could easily be grandparents. Or great-grandparents, or even great-great-grandparents, considering elephants normally start having babies at around age 12.Desktop Version
The dry days of winter in Etosha
The dry days of winter in Etosha
During the dry winter months from May to October, scattered waterholes sustain wildlife in the grasslands of Etosha National Park in Namibia. Large numbers of animals, such as elephants, giraffes, zebras, and our springboks here gather for a drink—making this among the best times of year to view wildlife. A medium-sized antelope, springboks are native to the dry savannahs of southern Africa where they once migrated in large numbers. Today, springbok herds live mainly on game preserves and protected areas like the 8,600 square miles within the Etosha boundaries.Desktop Version
Crescent Lake near Dunhuang, China
Crescent Lake near Dunhuang, China
Crescent Lake is a captivating natural wonder hidden in the vast Gobi Desert near the Chinese city of Dunhuang in Gansu province. This oasis, named for its unusual shape, has been a vital water source here for centuries. The lake is thought to have formed in a valley carved by wind and been fed by an underground spring. It sits amid Dunhuang"s "singing" sand dunes, which make a noise when the wind blows. The sand dunes also help stop the lake from being swallowed by sand and conservation efforts have ensured that it doesn"t dry out. Visitors enjoy boating on the lake, camel rides through the surrounding dunes, and seeing ancient Buddhist art and murals in the nearby Mogao Caves.Desktop Version
Where the bearded reedling sings
Where the bearded reedling sings
Feeling a hint of fall in the air? This bearded reedling could be, but a drop in temperature isn"t a signal for it to fly on to warmer destinations. These songbirds belong to a resident species, which means most stay put in the marshes, from England to eastern Asia, where they thrive. Their diet changes with the seasons: In the summer, they dine on reed aphids, while during the colder months, reed seeds sustain them. This guy—and we know he"s a male due the distinctive black "mustache" stretching down his face—is perching in the Elmley National Nature Reserve in Kent, one of the largest bird reserves in England.Desktop Version

This opulent room is the Golden Hall, a banquet hall in Stockholm City Hall, which will be one of the venues for today"s Nobel Prize award proceedings. The room, which is completely covered in mosaic tiles, includes representations of Swedish history and culture. Swedes refer to their capital as Mälardrottningen—the Queen of Lake Mälar—and our image depicts the queen with the city of Stockholm in her lap (the city lies between the lake and the Baltic Sea).Desktop Version
Reflections on the mighty Amazon
Reflections on the mighty Amazon
For World Rainforest Day we take you below these clouds to the Amazon River Basin and the largest rainforest in the world. Numbers help the story of this extraordinary place: At more than 2.1 million square miles, the Amazon accounts for half of Earth’s remaining tropical rainforests. And a fifth of the world’s fresh water flows through this river basin. Perhaps a tenth of the planet’s known species call it home, many of which have yet to be identified—that’s trees, plants, fish, mammals, and a third of Earth’s bird species. Now take a deep breath. The ‘Lungs of the World’ produces 20 percent of Earth’s oxygen, while storing vast amounts of carbon dioxide, earning it an all-star ‘carbon sink’ status.Desktop Version
Traffic jam on the caribou highway
Traffic jam on the caribou highway
Today we"re in Kobuk Valley National Park in Alaska to witness one of the world’s great annual migrations. Every spring, a quarter million caribou come together to form the Western Arctic Herd and pass north through the 1.8-million-acre park to their summer calving grounds in the Brooks Range and its foothills. Then in the fall, the caribou make the reverse trip, heading south back through the park to where they spend the winter in the Nulato Hills and the Seward Peninsula. One of the best spots to see the herd on the move is where it crosses the Kobuk River at Onion Portage. This area is a major archaeological site too. For thousands of years, the crossing has drawn native groups that rely on caribou meat, a tradition that continues to this day.Desktop Version
Jaguar in the Pantanal wetlands
Jaguar in the Pantanal wetlands
What"s the best place to see a wild jaguar? The Amazon rainforest may be more well known, but the Pantanal is the world"s largest tropical wetlands—and the place you"re most likely to spot a jaguar in the wild. The Pantanal"s estimated 70,000 square miles cover part of the western side of Brazil and extend into Bolivia and Paraguay. Portions of the Pantanal are protected within national parks and a UNESCO World Heritage Site. It"s difficult to travel there during the wet season (November-April)—high temperatures make it nearly unbearable, and rain and flooding often close roads. Hotels in the region even shut down for periods of time each year. May through September is the dry season, when temperatures cool off and conditions are more friendly to both people and many animals. If you plan to visit, pack some binoculars and keep your eyes peeled for a big spotted cat sitting blithely on the riverbank.Desktop Version
Pearl Harbor Remembrance Day
Pearl Harbor Remembrance Day
Today we"re in Hawaii to mark the 80th anniversary of the surprise attack on the US naval base in Pearl Harbor on December 7, 1941. The strike by Japan cost 2,403 service members and civilians their lives, injured 1,178 others, and thrust the US into WWII. The sailors you see here are standing on the deck of the USS Bowfin, a US Navy submarine that is now a memorial and museum moored in Pearl Harbor next to the Pearl Harbor Visitor Center.Desktop Version
