A cliffside harbor in Sardinia
A cliffside harbor in Sardinia
The mining industry in Sardinia, Italy, was booming in the early 20th century, as European nations looked to reconstruct from the damage of World War I. But Sardinians faced myriad logistical issues trying to export the zinc, lead, and other minerals that were in high demand. Miners on the island were using modern techniques to extract more and more ore, but it wasn"t until 1924, when engineer Cesare Vecelli designed and built the mining infrastructure along the cliffs in Porto Flavia, that getting ore off the island matched their ability to extract it.Desktop Version
Celebrating Norwegian Constitution Day
Celebrating Norwegian Constitution Day
If you have Norwegian roots, May 17 is a day to celebrate. It was on this day in 1814 that the Constitution of Norway was signed, declaring Norway an independent kingdom. This historic neighborhood in Trondheim, Norway, would be an ideal place to celebrate. Trondheim is the Norway’s third-largest city, founded by Viking King Olaf Tryggyason in 997. Today, its colorful wharfs and waterways charm visitors from around the world.Desktop Version
At the foot of Dubrovnik s Gibraltar
At the foot of Dubrovnik s Gibraltar
The stairs in today"s photo lead to Fort Lovrijenac, an 11th-century fortress jutting out into the Adriatic Sea just outside the western wall of Dubrovnik, Croatia. "Game of Thrones" fans will recognize these doors as entrances to a dwelling in the fictional city of King"s Landing. Legend claims that when the fort was built on this rocky coastal outpost, it took just three months to construct. The locals of what was then Ragusa knew they had limited time before their rivals, the Venetians, would arrive to build their own outpost and rule over them. According to "The Chronicles of Ragusa," the plan worked—the fort was completed just as the surprised Venetians arrived in ships heavy with supplies.Desktop Version
Of balloons and lost pantaloons
Of balloons and lost pantaloons
We all fly by the seat of our pants now and then, but how about flying with no pants at all? That was the plight of Jean-Pierre Blanchard and John Jeffries, who on January 7, 1785, made history over these chalk cliffs with the first aerial crossing of the English Channel. When their hydrogen-filled balloon dropped altitude due to overloading, the two tossed all the cargo they could into the drink below, britches included. Reaching France in their underpants, the undoubtedly chilly pilots still received a warm welcome.Desktop Version
Singing praises of the oceans
Singing praises of the oceans
In Japan, mid-July brings an excuse to head to the beach. That"s because this time of year marks Marine Day (aka Ocean Day), an observance recognizing the close bond the island nation shares with the seas and ocean that surround it. Because Marine Day roughly coincides with the end of the rainy season, it has, over the years, become a sort of unofficial kickoff to the hot summer season. One place sure to attract visitors is the picturesque Minokake-Iwa rock formation seen here, lying off the island of Honshu and its mountainous 31-mile-long Izu Peninsula.Desktop Version

To kick off National Park Week, which begins today, we"re visiting America"s newest national park, the New River Gorge National Park and Preserve, in West Virginia. This incredible view is of the New River Gorge Bridge, which, when completed in 1977, was the world"s highest bridge carrying a regular roadway. It held that distinction for 24 years and is now a popular attraction for BASE jumpers and rappelers.Desktop Version
Hello, harbinger of spring
Hello, harbinger of spring
Welcome back, little mountain bluebird. Although this bright fellow may be enduring the last of this year"s snow in Yellowstone National Park, his presence means winter will soon be ending. The bluebird is a symbol of happiness and a welcome sign of spring in many cultures. Soon other migratory birds will arrive in the Greater Yellowstone Ecosystem—an 18-million-acre tract that includes Grand Teton National Park and surrounding national forests. It"s the world"s largest intact ecosystem in the northern temperate zone. What exactly does that mean? Since wolves were reintroduced to Yellowstone 25 years ago, all the animal species that were first documented by European explorers can still be found here.Desktop Version
Longtailed widowbird at Rietvlei Nature Reserve, South Africa
Longtailed widowbird at Rietvlei Nature Reserve, South Africa
With a name like ‘widowbird,’ you’d expect this dusky male to have a low-key love life. But those 20-inch-long tail feathers are highly favored by females, even though they can make it difficult for the males to fly on windy days. The display has been the subject of much study regarding sexually selected traits and the tradeoffs between physical constraint and attracting a mate, since the tail feathers don’t seem to aid in flight and may even cause a hinderance. Ah, the things we do for love.Desktop Version
Seven Magic Mountains art installation, Jean Dry Lake, Nevada
Seven Magic Mountains art installation, Jean Dry Lake, Nevada
It’s easy to see how this brightly colored art installation near Jean Dry Lake caught the eye of photographer Renz Alfonso Dela Pena, the winner of the Bing #Amplifyingenuity photo contest. The installation, created by artist Ugo Rondinone, includes seven towers of boulders that reach up to 30 feet high. Its bold colors are meant to contrast with the stark landscape here in the Mojave Desert, where the piece will remain on display at least through 2018.Desktop Version
A willowy welcome to spring
A willowy welcome to spring
With winter officially over, we"re weeping for joy right alongside this willow tree, its wispy new boughs signaling a healthy year of growth to come. About 400 species of willow grow across the globe in water-rich, seasonally chilly spots like here in Minnesota. With some willows soaring up to 70 feet tall and wide, cultures around the world have bestowed deep symbolism on the formidable trees, associating them with refuge, wisdom, or plenty—if not with ghosts, demons, or the spirit world. One thing all traditions can agree on: When a willow sprouts bright green wisps like this, it"s a welcome symbol of spring"s arrival.Desktop Version

Think deep thoughts
Some of you Navy vets—and fans of "20,000 Leagues Under the Sea," "The Hunt for Red October," or "Das Boot"—might get a familiar wave of claustrophobia from today"s picture. For National Submarine Day, we"re in the forward engine room of the USS Drum, a historic US Navy submarine displayed at Battleship Memorial Park in Mobile, Alabama. The Drum was the first deployed of the Gato-class subs—the line of boats that, with variations, made up most of the US submarine force during World War II. Decommissioned shortly after the war, the submarine is now in dry dock and open for public tours.Desktop Version
Marine Day in Japan
Marine Day in Japan
In Japan, the third Monday in July is Marine Day (also known as Ocean Day), a day to show appreciation for the seas and oceans. Other nationalities have similar observances, but as inhabitants of an island nation, people in Japan can claim a particularly strong connection to the waters that surround them. The modern holiday also serves as an official start of summer in Japan, and many folks hit the beach to celebrate the end of tsuyu, the rainy season. The holiday started as Marine Memorial Day in 1941 to mark the anniversary of the return of the Meji Emperor from a voyage in 1876, but it wasn"t observed as a national holiday until 1996. Some also mark Marine Day with environmentally friendly activities. In Okinawa, people throw EM (effective microorganism) mudballs into the sea—these contain bacteria and yeast targeted at eliminating sludge and slime. Other areas host beach cleanups and aquariums host special Marine Day events.Desktop Version
Travel Sunday: Liverpool
Travel Sunday: Liverpool
We approach Liverpool, our Travel Sunday destination, by the River Mersey. And to hear natives of Liverpool tell it, the Mersey is the only river that matters. The Mersey helped build Liverpool into a powerful port city during the 19th century as industrialization really took hold. Today, you may know Liverpool by some of the famous musicians—Beatles, cough—that got their start in a city once called ‘the New York of Europe.’Desktop Version

We don"t really need an excuse to feature this adorable photo of twin cubs asleep inside a snow den in Wapusk National Park in Manitoba, Canada. But it just so happens that today is International Polar Bear Day, the perfect day for this shot from the 2007 documentary film "Earth," which focuses on wild habitats and creatures across the planet.Desktop Version
A place fit for the gods
A place fit for the gods
Perhaps it was inevitable that this park on the western edge of Colorado Springs was named Garden of the Gods. One of the surveyors who established the city was so struck by the beauty of the rock formations here that he thought it a suitable setting for the gods to assemble, and so lent the spot its name. But the native Ute people also have divine associations with the area, which their creation myth names as the place where all life began. Today, it’s a popular public park and National Natural Landmark. Because it’s within the city limits, locals and visitors alike can get a heaping dose of nature without having to travel far from civilization. If you stroll by any of the rock formations here, you’re likely to see a climber or two scaling the red and pink sandstone walls—or ‘fins’—that give the park its distinct look.Desktop Version
A whale of a hug
A whale of a hug
This time of year, humpback whales make their annual trip to the warm waters of the South Pacific to mate. Today"s image finds us swimming alongside a humpback mother and her young calf near the Polynesian island chain of Tonga. There are six main humpback populations in the southern Pacific, and this pair is part of the one that"s often called the "Tongan Tribe." The humpbacks of the Tongan Tribe return each year from their feeding grounds off Antarctica—a journey of more than 4,000 miles. Through November, the cows will stay in this region while their newborn calves grow strong enough to make the trek back to the cold Antarctic waters where their main food source—the small crustacean called krill—is abundant.Desktop Version
Caribou on the move
Caribou on the move
Each fall a quarter-million caribou come together to form the Western Arctic Caribou Herd, a group that makes an epic migration through northwest Alaska. The caribou move south from their calving grounds in the Utukok River Uplands to their winter range on the Seward Peninsula. Fall is also the time when scientists attach radio collars to members of the herd, to track their location and health, and to gain information that will help conserve the species. When spring arrives, the caribou will complete the trip again in reverse, covering a total of 2,000 miles each year, give or take.Desktop Version

Our National Park Week virtual tour comes to a close at sunset on Ruby Beach, one of the many stunning corners of Olympic National Park in Washington state. A few miles from the shore is Destruction Island, where birds such as rhinoceros auklets may stop and rest after a day of gobbling up krill and squid in the cold Pacific waters. While the park includes miles of colorful Pacific coastline, it"s also famous for the Hoh Rainforest, an inland temperate forest notable for its towering old-growth hemlock and spruce trees.Desktop Version

For International Red Panda Day, we"re hanging out on a tree limb with this cutie in the Chengdu Panda Base of Sichuan, China. If you spot a red panda in the wild, consider yourself lucky. Not only will you have to travel far (they live in the mountain forests of Nepal, Bhutan, China, Myanmar, and India), but there are fewer than 10,000 wild red pandas, and they"re rather elusive, hanging out up in trees. They also spend more than half their day asleep, conserving energy for—you guessed it—eating bamboo leaves. They spend a whopping 13 hours a day eating.Desktop Version

The Amazon rainforest is big. Almost unimaginably big. To begin to grasp its immensity, consider these numbers: The Amazon rainforest covers about 2% of the world"s surface area, nearly 2.1 million square miles across South America, mostly (nearly 60%) in the country you see here, Brazil. It"s an area that accounts for over half the Earth"s remaining rainforests. The breadth of biodiversity is incomparable—nearly 16,000 different tree species, 40,000 species of other plants, 2.5 million insect species, and over 2,000 different types of birds and mammals. Incredibly, perhaps a tenth of the planet"s known species call the Amazon home, many of which have not even been identified.Desktop Version
In search of a ‘great’ pumpkin
In search of a ‘great’ pumpkin
It’s not too late to visit a pumpkin patch like the one in our homepage image and pick an orange orb to carve up this Halloween. Or, if you’re like a certain Peanuts character, you still have time to search for the Great Pumpkin. Linus’ quest to glimpse this unseen character is of course featured in ‘It’s the Great Pumpkin, Charlie Brown,’ the animated Halloween special that first premiered in 1966. Linus believed the Great Pumpkin delivered toys to children on Halloween night. Some have interpreted the Great Pumpkin as a symbol of faith, and others see Linus’ quest to see the Great Pumpkin as a metaphor for humankind’s existential crisis. Whatever the case, the film is a classic and worth rewatching.Desktop Version

Welcome to Acadia National Park on Maine"s rocky, scenic coast. The 49,075-acre park covers about half of Mount Desert Island, smaller nearby islands, and a section on the mainland. The oldest national park east of the Mississippi River and the only one in Maine, Acadia packs a lot of geographical variety into its relatively small size. You"ll find miles of craggy coastline like the shore in our homepage image, woodlands, wetlands, and mountains. The park"s Cadillac Mountain is the highest point along the North Atlantic seaboard and a great spot to take in the sunrise.Desktop Version

It s a good day to be green
For St. Patrick"s Day, we"re featuring an image of the Knowth passage grave, part of Brú na Bóinne, or the Boyne Valley tombs, about an hour"s drive north of Dublin. In addition to Knowth, this UNESCO World Heritage site is home to the Newgrange and Dowth passage graves, henges, standing stones, and a significant portion of Western Europe"s megalithic art. Knowth, the largest passage grave in the complex, is a 40-foot-high mound with a diameter of 220 feet; two east-west passages run under it that lead to separate burial chambers. The structures predate St. Patrick by nearly 4,000 years, and their original purpose is unclear—but on this day dedicated to celebrating all things Irish, they show off the engineering capabilities of the area"s ancient population as well as the natural green beauty of the Irish countryside.Desktop Version
The story of a rediscovered redwood
The story of a rediscovered redwood
Like most things in nature, the trees featured on today’s homepage are worth a closer look. This species, known as the dawn redwood, was thought for hundreds of years to be extinct. Unlike other redwood trees (picture the towering evergreen giants that grow on California’s coast), this redwood is deciduous; in the fall its needles turn a brilliant orange, and then fall to the ground. Fossils of the species are common in the Northern Hemisphere, but there was no known evidence that it existed after the Miocene Epoch, which ended more than 5 million years ago. The tree was thought to have been long extinct until 1944, when a giant dawn redwood was discovered in south central China. More were found in surrounding lowlands, and today the tree is a popular ornamental in many parts of the world. The trees in our image, from Zhongshan, China, are standing in a shallow lake, which reflects the blue sky above.Desktop Version
