Prince Christian Sound in southern Greenland
Prince Christian Sound in southern Greenland
The sheer size of Greenland is hard to put in perspective. The world"s largest island is more than 836,000 square miles—that"s more than three times the size of Texas and 170,000 square miles larger than Alaska. It is a land of deep fjords and thick ice that must have made the Norse explorers feel right at home when they landed there a thousand years ago.Desktop Version
Martin Luther King Jr. Day
Martin Luther King Jr. Day
Martin Luther King Jr. Day serves as a reminder not only of the man, but also of his mission. He stood for advances in civil rights, nonviolent resistance, and a dream of racial harmony. In 1983, the third Monday of January was made a federal holiday to mark his birthday, which was on January 15. It"s the only federal holiday that"s designated as a national day of service and the "day on, not a day off" continues to inspire unity, progress, and the ongoing struggle for equality.Desktop Version

Earth Science Week
Hundreds of shades of blue are marbled together in this cool shot. No, it"s not a work of modern art, it"s right off the brush of nature. This is a satellite photo of phytoplankton blooming near Alaska as the cool, salty Chukchi Sea mingles with warmer, fresher water closer to shore.Desktop Version
Cordouan Lighthouse, France
Cordouan Lighthouse, France
Built between 1584 and 1611, the Cordouan Lighthouse is France"s oldest working lighthouse and the only one in the country that is still inhabited by keepers. For centuries, this maritime marvel has watched over the Gironde Estuary, on France"s Atlantic coast, a treacherous area where shipwrecks were once common.Desktop Version
Haven t you herd? It s World Elephant Day!
Haven t you herd? It s World Elephant Day!
Maybe this shot reminds you of that scene in "The Jungle Book" where a regiment of elephants thunders through India"s dense brush. We"re actually looking down at the wetlands of Botswana, a country that boasts a pachyderm population of 130,000—more elephants than any other nation. Unfortunately, herds here in the Okavango Delta have been hit hard recently: Mysterious die-offs in 2020 claimed about 350 local African bush elephants—and the deaths have continued, albeit at a lesser rate. Though the problem is still being studied, it"s theorized that high water temps gave rise to poisonous algae blooms in the animals" watering holes.Desktop Version
Welcome to my neck of the woods
Welcome to my neck of the woods
It"s peak tourist season in the Tsavo region of Kenya, when the weather"s cooler and dry—a good time to spot wildlife like this gerenuk in Tsavo National Parks. The protected area is actually made up of two separate parks, Tsavo East National Park and Tsavo West National Park, separated by a highway and rail line. Together they cover 8,036 square miles, with the East park consisting of flat, dry plains, and the West including mountains, volcanoes, lakes, and springs. The gerenuk (which means giraffe-necked antelope in Somali) is a long-necked antelope also known as the giraffe gazelle. It uses its lengthy neck and ability to stand on its hind legs to nibble on shrubs and trees that other types of antelope can"t reach. It"s less social then other gazelles, so seeing one alone, as we are in this photo, is common.Desktop Version

Muniellos Nature Reserve
The Muniellos Nature Reserve is one of Spain"s best-preserved forests of Quercus robur, otherwise known as common oak, European oak, or English oak. The 13,560-acre reserve in Asturias province also includes sessile oaks, seen in our photo alongside beech trees.Desktop Version
Salmon return to the Copper River
Salmon return to the Copper River
This is the vast delta of the Copper River in south central Alaska. The river is known for its large salmon run, which starts in early May when the sockeye and king salmon come back in huge numbers to spawn. Accompanied by much marketing fanfare, this Copper River catch also signals the return of fresh wild Pacific salmon to grocery stores and restaurants. The price per pound, especially in the early days of the commercial season, is as rich as the fish are in Omega-3 fatty acids.Desktop Version
It’s surströmming time
It’s surströmming time
The historic wooden pier of Smögen, Sweden, will be busy—and pungent—today. The third Thursday in August means one thing: surströmming season has arrived and all over Sweden, brave residents stand at the ready with can openers in hand. If you"ve never taken part in a surströmmingsskiva, the Swedish word for this particular event, you"re going to need a bucket of water, some side dishes, and a strong constitution.Desktop Version
A cry for independence
A cry for independence
The Palacio de Bellas Artes in Mexico City has hosted art exhibits, music and dance performances, and much more since its opening in 1934. The ornate Art Nouveau building was originally planned to open years earlier in 1910 to mark the 100th anniversary of Mexico"s independence from Spain. Even though it missed that 1910 deadline, the Palacio de Bellas Artes is still considered a symbol of Mexican independence. To get the story of how Mexico broke with Spain, we must travel 200 miles from this spot and back in time to the early 1800s.Desktop Version
Silver-studded blue butterflies
Silver-studded blue butterflies
The butterfly effect is a scientific concept coined 50 years ago today, and it has become a literary and metaphorical term to describe the idea that the smallest change may have massive, worldwide implications. It is often associated with chaos theory. American mathematician and meteorologist Edward Norton Lorenz theorized that the flapping of a butterfly"s wings, like those of the silver-studded blue butterflies you see in today"s image, could weeks later influence the formation of a tornado.Desktop Version
With leaves this tasty, who cares about a view?
With leaves this tasty, who cares about a view?
In the canopy of Uganda"s Bwindi Impenetrable National Park, a mountain gorilla leans into a meal of succulent green leaves. By day"s end, she"ll likely eat close to 40 pounds of foliage. Locals call this forest Bwindi, which means "impenetrable," but to this mountain gorilla, it"s simply home. Like us (and most primates), these gentle giants have opposable thumbs, which makes picking and eating an easy task. Also like us, mountain gorillas prefer hanging out on the ground. In fact, they"re known to stand upright and walk short distances with a remarkably human-like gait. We humans share 98 percent of our DNA with gorillas (both the eastern and western species), nearly as much as we share with chimps and bonobos. So yes, even though they have more body hair, we"re all hominids.Desktop Version
Yosemite National Park, California
Yosemite National Park, California
Fancy witnessing a fiery waterfall? The seemingly impossible can be found at this time of year on the eastern side of El Capitan, Yosemite National Park"s famous rock face. Horsetail Fall is a seasonal waterfall that flows only when there has been plenty of snowfall, and when temperatures have been warm enough to melt it. For a couple of weeks in February, if skies are clear, water is flowing, and the sun shines at just the right angle, the long, slender waterfall takes on a glowing, flame-hued appearance. Hundreds gather in Yosemite Valley to see this mesmerizing natural spectacle. The phenomenon has earned the moniker "firefall," an homage to the historic Yosemite Firefall, a manmade event from the top of the park"s Glacier Point that took place between 1872 to 1968. Eventually, park rangers decided that dumping embers over a cliff onto the land below wasn"t the brightest idea.Desktop Version
Mount St. Helens National Volcanic Monument, Washington
Mount St. Helens National Volcanic Monument, Washington
We"re standing on the Boundary Trail at Johnston Ridge in the Mount St. Helens National Volcanic Monument. This view of the volcano shows how the eruption of Mount St. Helens on May 18, 1980, ripped apart the once-conical summit, forever changing the Washington landscape. Forty years ago today, 110,000 acres within Gifford Pinchot National Forest were set aside to memorialize the deadliest and most destructive volcanic eruption in the United States.Desktop Version
World Water Day
World Water Day
Lake Powell, which meanders across the Utah-Arizona border, was created when the Glen Canyon Dam was built on the Colorado River in the 1960s. It is one of the two largest reservoirs in the US, alongside its downstream neighbor Lake Mead. Together, they provide water to about 40 million people in seven states, while their respective dams generate crucial hydroelectric power.Desktop Version
Ravens
Ravens
With their black feathers standing in sharp contrast to the misty Alaskan background, this group of ravens perched on a leafless tree conjures up a fitting image for this spooky time of year. In the folkloric traditions of many cultures around the world, these highly adaptable, intelligent birds have been considered symbols of all manner of unpleasantness. In Chinese mythology, they"re blamed for bad weather, while Celts associated them with warfare. In some Native American traditions ravens are often represented as mischievous tricksters, while many European cultures associate them with evil spirits, usually of demonic origin. In English, a gathering of ravens like this is even called an "unkindness"!Desktop Version
Mediterranean red sea stars
Mediterranean red sea stars
Sea stars—often called starfish—are some of the most fascinating creatures to live in our oceans. For starters, despite their name, they aren"t fish—they belong to a group of marine invertebrates called echinoderms. Like all echinoderms, sea stars are characterized by the radial symmetry of their bodies, which usually have multiple arms extending from the central disc.Desktop Version

Florentine garden brings generations together
Florentine garden brings generations together
Because it’s hidden just beyond the walls of the Palazzo Corsini al Prato, the Corsini Garden is never seen by many of the tourists who visit the grand palace. You’ll find the garden and palace in Florence, the birthplace of the Renaissance and capital of Italy"s Tuscany region. Designed by architect Bernardo Buontalenti in the early 1590s, the Palazzo Corsini al Prato and Corsini Garden will host the third annual New Generation Festival this week. The festival features a "new generation" of musical talent from around the world performing in a different musical genre each night. For four nights, young and old will enjoy opera, jazz, and classical music in an Italian garden that has enchanted visitors for more than a dozen generations.Desktop Version
Palouse farmland, Washington state
Palouse farmland, Washington state
The Palouse region in the Pacific Northwest is known for its picturesque landscapes, agricultural heritage, and unique geological features. Those stunning hills in our homepage image were formed over tens of thousands of years, from dust and silt blown by the wind, known as loess. The Palouse"s fertile soil and climate make it ideal for farming and it is known for its wheat, barley, lentils, and other crops. With its beautiful rolling hills covered in patchworks of green and golden fields, it is often compared to Italy"s Tuscany region or the French countryside.Desktop Version

Who s hiding in the kelp?
This California sea lion is peeking out from a kelp forest near the Channel Islands of California. Although this species is named for the Golden State, the California sea lion"s range stretches all along the western coast of North America, from central Mexico up to Southeast Alaska. They tend to live in shallow coastal areas, dining on squid, anchovies, mackerel, and more. Highly social and intelligent, California sea lions often congregate in large—and loud—colonies on beaches and rocky shores to breed and have their pups.Desktop Version
Diwali
Diwali
Diwali is a five-day celebration of the symbolic victory of light over darkness, good over evil, and knowledge over ignorance. Though Diwali is one of the most important festivals of the Hindu faith, it is also embraced by Sikhs, Jains, and even some Buddhists. Celebrants often decorate their homes with oil lamps called diyas and create colorful patterns on the floor known as rangolis. Streets, markets, temples, and other public spaces are also illuminated with hanging lanterns like those seen in our homepage photo.Desktop Version
Cousins Day
Cousins Day
When it comes to honoring family members, parents and siblings get most of the attention—but today, let us sing the praises of our cousins on Cousins Day! These extended family members hold a special place in our hearts. They"re not quite siblings, but more than mere friends. When we"re young, they"re the buddies we go adventuring with, while the adults stay behind to make small talk. Maybe you"ve fallen out of touch with your cousins, or maybe you"re still close—either way, today"s a great day to reach out, say hello, and reminisce. That"s what it looks like these zebras are doing; there"s likely a set of cousins or two in this group that"s horsing around on the savannah in Tanzania.Desktop Version
Darwin s Arch
Darwin s Arch
On Darwin Day, we visit Darwin"s Arch, named for the famous English naturalist Charles Darwin, who was born on this day in 1809. The last time the sea arch looked as it does in this image was May 17, 2021. That"s when it collapsed due to natural erosion and became a pile of rubble between what is now two pillars. Some locals and scientists have renamed the rock formation the "Pillars of Evolution," a nod to Darwin"s theory of evolution by natural selection.Desktop Version
Here we honor the women who ve served
Here we honor the women who ve served
For this Memorial Day, we"re paying our respects at the Military Women"s Memorial, at the gateway to Arlington National Cemetery, just across the Potomac River from Washington, DC. Since the American Revolution, more than 3 million women have served the nation in a military capacity, and this memorial is dedicated to them, honoring their courage, patriotism, and leadership. Opened in 1997, it"s the only major national memorial to honor all the women who have defended the United States in, or with, the armed services. And it"s more than just a memorial. It"s also an education center, with thousands of photographs, documents, textiles, artifacts, and other materials representing all eras and services of American women"s military history.Desktop Version
