The migrating monarchs of Michoacán
The migrating monarchs of Michoacán
Probably the most recognizable of all the butterfly species, monarchs are helpful pollinators that can be found across the United States and Canada in the summer. But each fall, millions of these orange and black beauties embark upon one of the world"s most amazing migrations. The insects make use of air currents to make the long journey south to the mountains of southwestern Mexico, a flight of up to 3,000 miles. Aside from being a staggeringly great distance for these delicate insects to fly, it"s also a journey to a place that not one of them has ever been to before. And unlike the many bird species that undertake annual round-trip migrations, these butterflies will never return to the north. Why not? Because the distance and length of the total annual migration cycle is greater than the lifespan of individual monarchs.Desktop Version
Autumn in the cypress swamp
Autumn in the cypress swamp
Autumn still brings a splash of color to this hardwood forest of bald cypress in Louisiana. But make no mistake, a stroll through these wetlands is not a cozy New England leaf-peeping journey. The swamp forest floor is often covered by the waters of the Atchafalaya River delta as it drains into the Gulf of Mexico, so the autumn colors here are best viewed from the seat of a canoe or a pirogue, as the local Cajuns use. The water-resistant bald cypress trees thriving in the Atchafalaya Basin constitute the largest tract of contiguous cypress forest in the United States. The ecosystem here is so unlike any other in the US, the Atchafalaya National Heritage Area organization calls it "America"s foreign country."Desktop Version
1, 1, 2, 3: It s Fibonacci Day!
1, 1, 2, 3: It s Fibonacci Day!
Today"s date, November 23, can be represented as 11/23, or 1, 1, 2, 3—the beginning of the Fibonacci sequence of numbers. Likewise, as the leaves on the Queen Victoria agave in today"s image spiral out from the center, they also express the Fibonacci sequence. This unique sequence of numbers was introduced to Europe in 1202 by the Italian mathematician Leonardo of Pisa (posthumously named Fibonacci) in his revolutionary work, the "Liber Abaci." The book begins by describing the Hindu-Arabic numeral system or "Modus Indorum’—0 1 2 3 4 5 6 7 8 9—and shows how its application could simplify trade and make calculations faster and easier (most of Europe at this time used Roman numerals).Desktop Version
The Cutty Sark turns 150
The Cutty Sark turns 150
We"re featuring the Cutty Sark in today"s image to mark the 150th anniversary of its launching on November 22, 1869. Built for speed, the Cutty Sark began its abbreviated career as a tea clipper racing across oceans "at a clip" (hence the designation "clipper ship") to deliver the season"s first tea harvest from China to England. While at times considered one of the fastest ships in the world, the Cutty Sark’s practical use as a cargo ship was ending almost as soon as it was launched. That"s because steamships using the much shorter route through the newly opened Suez Canal were able to deliver the highly anticipated tea harvest faster and more cheaply. In 1883, the Cutty Sark began hauling wool from Australia, but within 10 years steamships also disrupted this business.Desktop Version
Le Beaujolais nouveau est arrivé!
Le Beaujolais nouveau est arrivé!
"Bring us some fresh wine! The freshest you"ve got—this year! No more of this old stuff." Steve Martin was joking when his character in "The Jerk" asked for fresh wine—or perhaps he was talking about Beaujolais nouveau. The red wine, produced in the Beaujolais region of France, is fermented for just a few weeks and requires no barrel aging before it"s sold starting on the third Thursday of November. Beaujolais nouveau is a light-bodied red wine, with relatively high amounts of acidity. Located south of Burgundy, the Beaujolais region has a relatively warm climate, so Cabernet Sauvignon, Pinot Noir, and other famous French grapes don"t grow well there. But the fruity Gamay grows vigorously in Beaujolais and is used to make Beaujolais nouveau.Desktop Version
Atop the roof of Africa
Atop the roof of Africa
From their home in the Simien Mountains of Ethiopia, these rare gelada monkeys look like they"re on top of the world. Simien Mountains National Park has some of the highest elevations in all of Africa, marked by deep valleys, jagged mountains, and sheer cliffs. This harsh climate nurtures rare and endangered species, including our homepage friends. The gelada monkey lives only here in the Ethiopian Highlands, where it survives on a diet of mostly various grasses. Nicknamed the "bleeding-heart monkey," it"s recognizable by the bright red, hourglass-shaped patch on its chest. It has another claim to fame: This chatty species produces a diverse range of vocalizations so complex they"re thought to be similar to those of humans. So, what do you think they"re talking about?Desktop Version
Zion National Park Turns 100
Zion National Park Turns 100
It"s been exactly 100 years since President Woodrow Wilson signed legislation that established Zion National Park in southwestern Utah. Fewer than 2,000 people visited back in 1919 due to poor road conditions and lack of trails. These days, the park has the opposite problem—with more than 4 million people coming each year, crowds create long lines for shuttles and clog popular areas such as the Narrows. Part of Zion Canyon, the Narrows can be seen from a paved path. But many people like to experience it up close by hiking in the Virgin River, and it can get crowded at peak times since it"s—as the name implies—narrow.Desktop Version
Swimming with the sea cows
Swimming with the sea cows
In observance of Manatee Awareness Month, we"re swimming through a clear Florida river with these friendly "sea cows." Generally solitary animals, they are also known to be curious and will approach boats. That"s why Florida enforces special speed zones for watercraft, particularly as the manatees are on the move to warmer areas to spend the winter. While manatees have no known natural predators, they remain a vulnerable species due to loss of habitat and collisions with boats.Desktop Version
Remembering the Velvet Revolution
Remembering the Velvet Revolution
Today we"re visiting Prague for the 30th anniversary of the start of the Velvet Revolution in what was then Czechoslovakia. On November 17, 1989, during their annual International Students Day observance, 15,000 students in Prague began demonstrating against the Communist Party"s authoritarian rule over the country. After the official end of the demonstration, the students continued marching to the center of the city. When they reached Národní Street, they were met by security forces who, after blocking all escape routes, began attacking. Afterwards, unfounded rumors of an injured or possibly dead student triggered strikes among students, actors, and others.Desktop Version
Mountain mists over Bavaria
Mountain mists over Bavaria
In modern German, the word for this month is "November." But an older German name was "Nebel-mond," which translates as "fog month" in English—it"s the time of the year when fog is most likely to roll in. In some parts of the world the topography and local climate make fog a regular feature of the weather, especially during certain times of the year. That’s called "fog season." San Francisco has a fog season. Tampa, Florida, does too. Is there a fog season where you live?Desktop Version
Mesmerizing murmuration
Mesmerizing murmuration
Around this time of year, as temperatures dip in the Northern Hemisphere, European or common starlings put on a dazzling show. Most of the time, these noisy birds are scorned for their bullying behavior at the bird feeder. But in autumn months, they gather to roost in huge flocks, as they’re doing here in Blackpool, England. At dusk, the starlings take flight en masse and flock together in a hypnotizing, swirling cloud of fluttering wings. These flocks are called mumurations. They"re thought to help keep the birds warm while also acting as a defensive tactic to confuse predators like hawks and falcons. But maybe the raptors are rendered harmless simply because they’re awestruck by the starlings" synchronized spectacle.Desktop Version

Since 2009, the city of Durham has served as a grand stage for the biennial Lumiere Durham festival. During four days in November, works of "son et lumière"—a French phrase that means "sound and light"—provide spectators with new ways of viewing public spaces and buildings. Artists from around the world design large-scale light shows paired with narratives and sound effects. It"s become the UK"s largest light festival, and Lumiere Durham"s 10th anniversary, which begins today, promises to attract more than 200,000 people to enjoy the illuminated artworks along cobbled streets.Desktop Version
Big-wave hunters watch Nazaré
Big-wave hunters watch Nazaré
Today"s image captures Brazilian surfer Rodrigo Koxa in action, surfing a record 80-foot wave off the coast of Nazaré, Portugal. Nazaré began attracting surfers in the 1960s and has since become a major destination for men and women who want to surf some of the world"s biggest waves. Nazaré"s Praia do Norte (North Beach) is the site of the two latest records for largest wave ever surfed. The previous record was set by American Garrett McNamara on November 1, 2011, when he rode a 78-foot wave here. Then, on November 8, 2017, Koxa set a new record with this ride.Desktop Version
Sleep tight, little hedgehog
Sleep tight, little hedgehog
Though they may seem exotic to most people in the Americas, wild hedgehogs are quite common in much of the rest of the world. The tiny creatures are usually nocturnal and use their spiky exteriors to protect themselves. Each hedgehog has about 6,000 quills, but the quills aren"t poisonous and don"t easily detach, like those of the also-quilled (but completely unrelated) porcupine.Desktop Version

On a Healing Field for Veterans Day
We"re featuring a moment captured back in 2013 of Vietnam War veteran Jake Thorn sitting in a Healing Field display of 2,013 flags in Aurora, Illinois. According to the Reuters photographer who took this picture, Thorn was telling two visitors about his time in the military. Visiting a Healing Field is just one of the ways communities across the country come together for Veterans Day to honor the men and women who have served in the armed forces.Desktop Version
Sunny day, sweepin the clouds away
Sunny day, sweepin the clouds away
On this day 50 years ago, public television stations first introduced to viewers a colorful community of monsters, birds, grouches, and ordinary people all living together on a friendly urban street. TV producer Joan Ganz Cooney had developed the idea for "Sesame Street." She was convinced that television, with its ability to quickly capture the attention of young children, could be used for good—to educate as well as entertain. With the help of Jim Henson, creator of the Muppets, "Sesame Street"s" unique cast of characters, skits, and animated videos introduced a new way to provide early education for young children.Desktop Version

We"re gazing at the Brandenburg Gate—a symbol of peace and unity—through a heart-shaped replica of a remnant of the Berlin Wall, probably the most potent symbol of the political division that once scarred the German capital. Today marks the 30th anniversary of the fall of the concrete barrier that once obstructed this view.Desktop Version

Chapel on the rock
Pace yourself—you"ll need to climb 268 stone steps to reach the entrance of Chapel St-Michel d"Aiguilhe (Chapel of St. Michael of the Needle). This historic church near Le Puy-en-Velay, France, is a UNESCO World Heritage Site that attracts visitors from around the world. It was constructed in 969 by a local bishop and dedicated to the Archangel Michael, the patron saint of mountaintops. Even before the chapel was built, the site had spiritual significance, as it was home to prehistoric dolmens (stone tombs) built by the Romans to honor their god Mercury.Desktop Version

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
Saffron in bloom
Saffron in bloom
It"s harvest time for saffron, the precious seasoning that"s mostly grown in Iran, but used in cuisines around the world. Saffron is derived from the saffron crocus, an autumn-flowering plant with purple petals as richly hued as the vivid crimson stigmas (called "threads") in the center of the bloom. These threads are carefully extracted by hand with tweezers and dried before they"re used for cooking. Each flower comes with just three threads, and it takes a lot of them—roughly 75,000 crocuses will yield just one pound of saffron. The entire harvest can last only about a week or two, because that"s the short life of the saffron crocus bloom.Desktop Version
Balloons and camels are two ways to catch a ride here
Balloons and camels are two ways to catch a ride here
Welcome to India"s largest camel and livestock festival, the Pushkar Camel Fair. Thousands of people travel across mountains and through the Thar Desert to buy and sell livestock and enjoy the carnival-like atmosphere here. The fair offers visitors many diversions, but it"s the camels who get top billing. Considered "ships of the desert," camels were domesticated by nomads thousands of years ago to carry goods across forbidding landscapes. When well fed and hydrated, a camel can travel great distances without needing water or food, sometimes for weeks. The humps on a camel"s back serve a purpose: they"re fatty deposits that act as a source of nutrition. Here, on the edge of the Thar Desert, the camel remains a mode of transport for nomads as well as a source for textiles, goods, and sustenance (did you know a camel"s milk does not curdle in the desert heat?). The camel is held in such high esteem, the Pushkar Fair even stages camel decoration contests.Desktop Version

Stepping stones in Tollymore Forest Park, Northern Ireland
If historic Tollymore Forest Park brings to mind knights and castles, it’s no surprise. The site in Northern Ireland was used as a filming location for the popular ‘Game of Thrones’ TV series. Encompassing 1,600 acres in County Down, the park is rich with lush greenery, but explorers will also find historic stone gates, bridges, and arches—some dating back to 1726.Desktop Version
It s time to fall back
It s time to fall back
While today"s image may look like a scene from the "Doctor Who" TV show, it actually shows workers maintaining Big Ben"s clock face. But like the Doctor, the show"s main character, today we"re all time travelers. This morning we fell back (or will fall back for night owls and insomniacs reading this before 2 AM) in time an hour for the end of daylight saving time. And like changes to "Doctor Who," this shift isn"t without controversy. Since the 1970s, many studies have tried to quantify the advantages or disadvantages that come with falling back and springing forward, but as yet there"s no definitive answer.Desktop Version

A national icon
If ever there was an animal that deserved some recognition, it"s the bison. Since 2012, National Bison Day has been observed on the first Saturday of November to acknowledge the animal"s cultural, historical, and economic significance—as well as its remarkable comeback. Bison were once plentiful in America. Tens of millions strong in the 1800s, they roamed in great herds, helping to diversify and maintain the prairie habitat. They also played an important spiritual role in Native American cultures. Settlement of the American West caused habitat loss and that, combined with overhunting, nearly wiped out the species altogether, until ranchers, conservationists, and politicians teamed up to save them. In 1907, 15 bison from the Bronx Zoo were shipped to a wildlife refuge in Oklahoma to revive the population. Fast forward to today, and around 20,000 bison roam on public lands in the United States. In 2016, President Obama named the bison the National Mammal of the United States.Desktop Version
