In praise of bogs, swamps, and marshes
In praise of bogs, swamps, and marshes
Swamps and bogs probably aren’t the first things that come to mind when you think of America’s celebrated landscapes. That’s a shame, since wetlands like these play a crucial role in the health of our ecosystems. In addition to providing unique habitat to the many species that call wetlands home, they filter water, provide a natural buffer from storms, absorb flood waters, and capture carbon from the atmosphere—helping to protect our planet from climate change.Desktop Version

Our mama manatee and her calf are gliding through the crystal waters of Three Sisters Springs in Florida. We hope these two remind you of a mother’s love. If you call home for Mother’s Day, here’s some trivia you can share to make mom proud: In 2017, the Florida manatee was reclassified from endangered to threatened in acknowledgment of improvements in its population.Desktop Version
Where the glow of the holidays lingers
Where the glow of the holidays lingers
On the shores of Lake Lucerne and bestride the River Reuss, you"ll find the medieval Swiss city that shares the lake"s name. Emerging from a Benedictine monastery founded here in 750, Lucerne is today the largest town in central Switzerland. The central of three ancient, covered wooden pedestrian bridges of Lucerne"s Old Town has a unique feature. The interior of the Kapellbrücke (Chapel Bridge) is painted with religious scenes and allegories to edify those walking across it to the nearby St. Peter"s Chapel.Desktop Version
Quebec City for Winter Carnival
Quebec City for Winter Carnival
Among all the pre-Lenten celebrations that take place around the world in February, the most famous are associated with warm-weather cities like Rio and New Orleans, where revelers party in elaborate costumes during the run-up to Ash Wednesday. It"s a different affair in Quebec City, Canada, pictured here, where participants in the Quebec Winter Carnival enjoy all things winter, from snow sculptures to sleigh races. This former frontier outpost, and little sister to Montreal, is known for its spirited embrace of the coldest, darkest season. So, it"s no surprise that its winter festival is the biggest in the Western Hemisphere. Our homepage image shows the grandiose Château Frontenac hotel, which opened in 1893, towering over the city"s historic Old Quebec neighborhood, a UNESCO World Heritage Site.Desktop Version
Goodbye, 2020!
Goodbye, 2020!
New Year"s Eve celebrations around the world will look a lot different this year, but as we ring in 2021 (and bid good riddance to 2020?) we can still enjoy this view of fireworks from a previous year in Spain. The cathedral in the background is the Basílica de Nuestra Señora del Pilar, which was constructed over centuries beginning in 1681, though several churches had been built on the site prior to that. On the left is the Puente de Piedra Bridge, which spans the Ebro River. It"s also known as the Bridge of Lions because statues of lions (symbols of the city) stand at each end of the bridge. Zaragoza is famous for its landmarks and architecture, as well as for local cuisine, and seasonal festivals—which we can only hope return soon.Desktop Version

Mercury in retrograde
Today we"re traveling to outer space to catch a glimpse of the Caloris Basin on the planet Mercury. This small planet—about the size of Earth"s moon—is riddled with craters, but none as spectacular as the Caloris Basin. One of the largest impact craters in the solar system, Caloris is about 950 miles across and ringed by mile-high mountains.Desktop Version
Going with the floe
Going with the floe
Welcome to Disko Bay near the town of Ilulissat, Greenland, where summer"s midnight sun will dip just below the horizon for only about an hour and a half tonight. In fact, for several weeks in the period around the summer solstice, the sun doesn"t set at all on Disko Bay. Technically, the "midnight sun" occurs in places north of the Arctic Circle or south of the Antarctic Circle when the sun remains visible at the local midnight. This natural phenomenon lasts from April to August in the northern regions of Greenland. (The opposite effect, polar night, occurs during winter months when the sun does not rise above the horizon.)Desktop Version
Moody skies over Valletta
Moody skies over Valletta
We approach from the Mediterranean to arrive at a 2018 European Capital of Culture: Valletta, Malta. This celebration of city-specific culture began in 1985, and since 2010 two cities have shared the title each year (Valletta shares the 2018 honors with Leeuwarden, in the Netherlands). Valletta, the southernmost capital of Europe, has a remarkable range of architectural styles throughout the city, from 16th-century churches to the ultra-modern Parliament House. Aside from its rich homegrown culture, Valletta reflects a variety of outside influences, including several jazz clubs and a Baroque music festival.Desktop Version
Kelp buddies
Kelp buddies
These sea otters in Alaska are floating amid kelp—an important flora friend to the endangered marine mammals. Sea otters live mostly in the water and use the thick blades of kelp to anchor themselves as they sleep and to keep their buoyant pups from floating away. Just as the kelp helps otters, sea otters help the kelp, too. They ensure the kelp"s survival by eating sea urchins. If sea urchin populations are left unchecked, these spiny vacuum cleaners of the sea destroy kelp forests by munching on holdfasts that tether kelp to the ocean floor. The resulting clear-cut areas, called urchin barrens, are devastating to the overall ecosystem. Kelp forests provide food and safe harbor for hundreds of fish species and other sea creatures. They also remove carbon dioxide from the air, a benefit to us all.Desktop Version
Polar bear season in Manitoba
Polar bear season in Manitoba
On the shore of Hudson Bay, the Canadian town of Churchill, Manitoba is remote, but the sights are worth the journey. From beluga whales and northern lights to the shipwreck of the SS Ithaka and the Sea Walls murals, there are many surprises here. Moreover, it is also known as the "polar bear capital of the world", thanks to its seasonal visitors. From October to November, these white giants pass through, waiting for Hudson Bay to freeze over so they can head out to hunt seals. Tourists can safely watch polar bears from the comfort of custom-built vehicles and a so-called "polar bear jail" helps to manage bear-human interactions. Are you ready for a wild adventure that"ll send chills down your spine, but in a good way?Desktop Version

Join us in celebrating World Water Day
The theme of this year’s UN-sponsored event, observed on March 22, is nature-based solutions for managing water resources. Organizers say that strategies like reconnecting rivers to flood plains and restoring wetlands have the potential to rebalance the water cycle and improve human health and livelihoods. Today we are proud to highlight the efforts of the Nature Conservancy, a global nonprofit working to conserve the lands and waters on which all life depends. Your support of their work makes a difference for people and nature.Desktop Version
The call of the wild in Alaska
The call of the wild in Alaska
Most visitors to Denali National Park and Preserve in Alaska come with a checklist for the "big five" mammals that live here: grizzly bears, moose, wolves, Dall sheep, and caribou like this small group walking along a ridge. These are barren-ground caribou, a migratory subspecies of caribou found across the Arctic band of North America to western Greenland. Barren-ground caribou migrate in large herds, some traveling over 600 miles one way between their summer and winter ranges. But the Denali herd, which numbers around 1,700 animals today, generally stays on the park"s 6 million acres. For good reason, too—it"s the only large herd that isn"t hunted.Desktop Version

Today we"re featuring an image of the Jardin des Tuileries and the Louvre to highlight the Paris Photo art fair happening through Sunday at the historic Grand Palais. Paris Photo is the world"s largest art fair dedicated to photography. Since 1997, the mission of the fair has been "to promote and nurture photographic creation and the galleries, publishers, and artists at its source." Starting today around 200 exhibitors, leading galleries, and specialty publishers, along with Parisian cultural institutions, will give visitors a unique look at both historical and contemporary photographic works of art.Desktop Version
Cold? What cold?
Cold? What cold?
As the Scandinavian saying goes, "There"s no such thing as bad weather, just bad clothes." The adventurer seen here near the top of our image is conquering the New England chill on a stand-up paddleboard, a cold ocean removed from Nordic shores. But this watery winter excursion embodies the Scandie stamina distilled in the Norwegian word friluftsliv, literally translated as "free air life"—the notion that any time is a great time to be outdoors, weather be damned.Desktop Version

Góða ólavsøku, from the Faroes!
The festival known as Ólavsøka spans several days, but officially July 29 is the big day of merrymaking in the Faroe Islands. What exactly are the Faroese people celebrating? Technically, they"re observing the death of Saint Olaf. The Norwegian King Olaf II is said to have died in battle on this day in 1030. A century later, he was sainted by the Catholic Church.Desktop Version

Season"s tweetings! Today is the first day of the 122nd annual Christmas Bird Count, said to be the longest-running citizen science project in the world. Between December 14 and January 5, tens of thousands of volunteer birdwatchers will participate in counts across the US, Canada, and many other countries in the Western Hemisphere. Organized by the National Audubon Society, each local count takes place in a 15-mile-diameter circle, where volunteers follow a specific route to record and often photograph every bird they see.Desktop Version

National Lighthouse Day brings us to Port Clyde, Maine, where Marshall Point Lighthouse keeps watch over the Atlantic. Lighthouses have long played an important role in seafaring, and for many, they symbolize a simpler, more romantic way of life. Many lighthouses offer tours and some even let guests stay overnight, so they can get a feel for the life of lighthouse keepers who once tended the lights in the days of oil lamps.Desktop Version
Lighting the way to new beginnings
Lighting the way to new beginnings
The Lantern Festival marks the final day of Lunar (aka Chinese) New Year celebrations, which began this year on February 12 when we ushered in the Year of the Ox. Traditionally, the day of the festival is filled with dancing, firecrackers, children"s games, and food—including tangyuan, balls of rice flour that are generally loaded with sweet fillings. After sundown, celebrants gather to light or observe lanterns like the ones we see here in Chengdu, China. The lanterns are made in all sizes, shapes, and colors, and sometimes illustrate historical or mythological scenes. This year, most public celebrations will be canceled or reimagined online due to COVID-19 concerns, but the spirit remains the same. Many think of lanterns as symbolic of a new start and a way to illuminate the future as a new year begins.Desktop Version
The birthplace of Cinco de Mayo
The birthplace of Cinco de Mayo
The church we see on the grassy hill was built after Hernan Cortez and his Spanish army conquered Cholula one October day in 1519. The Spanish ravaged the Aztec holy city that day, murdering 10% of its population and burning down the many pyramids that dotted the area. But just underneath this church, buried for centuries, lay an ancient secret never discovered by the Spanish. It"s the largest pyramid in the world, the Great Pyramid of Cholula, so large its enormous base would span several Olympic-sized swimming pools.Desktop Version

Penguin Awareness Day
Penguin Awareness Day
We"re celebrating Penguin Awareness Day in the Falkland Islands, taking a stroll with some king penguins. Kings are the second-largest penguin species, only outranked in stature by their emperor penguin cousins. And while the kings" tuxedo coloring gives them a dash of the debonair, it also provides an important and more practical purpose: camouflage. When the birds dive deep into the ocean looking for food, their black feathers disguise the birds from predators above, while their white undersides do the reverse. Kings are legendary for their diving prowess—in their quest for tasty squid and lanternfish, they can dive to depths of 300 feet, and some have even been spotted nearly 1,000 feet beneath the surface. Underwater, these flightless birds are the epitome of grace. On land, however, they are not so graceful, and waddle or "toboggan" on their bellies to get around.Desktop Version

The steep, angular summit of Ama Dablam rises behind Tengboche Monastery, a Tibetan Buddhist site resting at over 12,000 feet. Ama Dablam means "mother"s necklace": Its swooping shape is thought to evoke a mother cradling a child, and a dangling glacier on its southwest face is believed to resemble the religious pendants many Sherpa women wear. Situated in the nearby Khumbu Valley, Tengboche Monastery is a stop on the Sacred Sites Trail Project, a self-guided trek through holy places that dot Nepal"s Sagarmatha National Park.Desktop Version
On the rebirth of the Olympic Games
On the rebirth of the Olympic Games
Today marks the 125th anniversary of the first modern Olympic Games, held in Athens in 1896—1,500 years after they were banned by the Roman emperor. (The original games were held at least as far back as 776 BCE and probably earlier.) The 1896 Games were held in the Panathenaic Stadium, in the shadow of the Acropolis of Athens, shown here. Those newly revived games of 1896 included athletes from 14 countries, with the largest delegations from Greece, Germany, France, and Great Britain. The 43 events included a marathon, tennis, cycling, fencing, shooting, Greco-Roman wrestling, and swimming. And while some things haven"t changed over the years, some were pretty different back then. Swimmers were taken out to sea by boat for the longer races and had to swim back to shore. Winners were given a silver medal (copper for second place), as well as an olive branch and a diploma.Desktop Version

When king eider males line up in a dandy display like this, it"s likely because they"re courting a hen (or what birders call a "queen eider"). These colorful drakes aren"t your regular ducks. They"re sea ducks, a group that includes several large duck species that feed off the coast in salt water. As you can see, male king eiders have striking multicolored plumage and yellowish knobs above their bills that are said to resemble crowns. They, and the less-ornate brown females, make their home in the frigid waters along the Arctic coasts of northern Europe, North America, and Asia.Desktop Version

This time of year, from late January to early March, babies arrive on the Serengeti. At the height of the wildebeest calving season, thousands of calves are born every day. Moments after birth, these youngsters can walk, and in just a few days, they"ll be able to run fast enough to keep up with the herd. That"s a good thing. Calving season isn"t just a draw for safari tourists wanting a front row seat at the start of the circle of life, but also for predators like lions, cheetahs, and hyenas on the hunt for easy prey.Desktop Version
