Petrified Forest National Park
Petrified Forest National Park
The burliest lumberjack with the best-oiled chainsaw couldn"t slice the massive "timbers" found in Petrified Forest National Park in northeastern Arizona. So why are these giant stone logs segmented in such symmetrical rounds, as if they"re ready to be split into firewood?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
Norway s Kjeragbolten boulder
Norway s Kjeragbolten boulder
If you have nerves of steel, you"d enjoy the precarious, one-of-a-kind photo op that is the Kjeragbolten boulder. Visitors climb up Kjerag, a mountain on the southwest coast of Norway, for the chance to clamber onto the stranded rock and have their daredevil pic snapped for posterity. Indeed, Kjeragbolten is so popular that you might have to wait up to an hour for your turn—plenty of time for second thoughts and jitters.Desktop Version

El Valle de la Luna, Chile
El Valle de la Luna (the Valley of the Moon) is located in the Atacama Desert of northern Chile. The Achaches Lookout, seen here, offers breathtaking views of volcanoes in the distance. In 1982, El Valle de la Luna was declared a nature sanctuary for its stunning, untouched habitat and its peculiar lunar-like terrain.Desktop Version
Pretty, pretty…butterfly?
Pretty, pretty…butterfly?
Not quite. This winsome winged creature is a moth, a Loepa oberthuri to be exact, a type of silkmoth. It"s the star of our homepage because today marks the start of National Moth Week, which shines the porch light on this unlikely hero. Unlike their showier cousins, butterflies, moths get a bad rap from time to time, and that"s fair, as caterpillars of some moth species are agricultural pests. But before you break out the mothballs, consider this: Scientists estimate that there are some 160,000 species of moths worldwide, many just as stunning as our silkmoth today, and tracking their health often helps us gauge the health of entire ecosystems. So we encourage you to investigate moths this week right in your own backyard. All you have to do: Turn on the porch light—and the moths will come calling.Desktop Version

Overseas Highway, Florida Keys
Overseas Highway, Florida Keys
Once upon a time, there lived a wealthy industrialist, Henry Flagler, who embarked on the herculean task of creating an overseas railway connecting mainland Florida to Key West. When it opened in 1912, it was dubbed the Eighth Wonder of the World. However, the triumph was short-lived. It was hit by a hurricane on Labor Day, 1935 and the railroad discontinued operations. The railway was sold to the US government and rebuilt as an automobile highway, opening in 1938.Desktop Version
All eyes on moths
All eyes on moths
Quick! Can you find this moth"s head? If the markings on the wings distracted you for a second, score an evolutionary victory for this saturniid moth resting in Mole National Park in Ghana. It"s thought that moths, butterflies, and other creatures use this crafty form of mimicry, called eyespots, to either intimidate predators or draw them to attack less vulnerable parts of the body.Desktop Version
Bobbio, Italy
Bobbio, Italy
Between the metropolis of Milan—the fashion and design capital of Italy—and the fabled seaport city of Genoa, you"ll find this small river town in northern Italy. People have resided here since ancient times, at least as far back as the Roman era, but the town really began to flourish when the abbey was constructed in the 7th century. For much of the Middle Ages, the Bobbio Abbey and its vast library made the town a center of religion, culture, and learning.Desktop Version
Wake up, it s Darwin Day
Wake up, it s Darwin Day
On Charles Darwin"s birthday, we celebrate Darwin Day—and, of course, there"s no better place to do that than the Galápagos Islands. Darwin is best known for his theory of evolution by natural selection, which he published in his 1859 book "On the Origin of Species." During his travels to the Galápagos Islands years earlier, Darwin observed creatures that were similar from island to island but had slightly different adaptations to better survive in their specific environments. This became a key component of his research. The islands are home to thousands of unique species, including this Pinzon Island tortoise, which we see hatching from an egg at the Charles Darwin Research Station.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
Cloughoughter Castle, County Cavan, Ireland
Cloughoughter Castle, County Cavan, Ireland
Cloughoughter Castle sits on a small island in the middle of Lough Oughter, a huge complex of lakes and waterways in County Cavan in Ireland. Its first stones are thought to have been laid in the early 13th century by the Anglo-Norman de Lacy family, but the O"Reilly clan took possession of the area in 1233 and completed the castle"s construction. They retained control of Cloughoughter Castle for centuries, but by 1653, it had been bombed and abandoned. Since then, it has been in ruins, resplendent in a sort of tattered grandeur. It can only be visited by boat but, as a symbol of Ireland"s medieval heritage, it is a must-see for history and castle enthusiasts alike.Desktop Version
Women s suffrage at 100
Women s suffrage at 100
Today marks 100 years since women won the constitutional right to vote in the United States, and we"re in Nashville, Tennessee, to celebrate five monumental figures in the women"s suffrage movement. Why Nashville? Because it was Tennessee"s capital that became the final battlefront in the long fight for the Nineteenth Amendment. On August 18, 1920, the state legislature faced a choice: Should Tennessee become the 36th and deciding state to ratify the amendment, securing its place in the Constitution? The stakes were high as eight states had already rejected the measure—but thanks to some unexpected "aye" votes from known opposers (one representative switched his vote at the urging of his mother), ratification won out.Desktop Version
For Hispanic Heritage Month: Out of Many, One
For Hispanic Heritage Month: Out of Many, One
This giant portrait by Jorge Rodríguez-Gerada is called "Out of Many, One." It was installed on the National Mall lawn in October 2014 and remained for one month. The title not only refers to the motto of the United States (E pluribus unum, Latin for "out of many, one") but hints at how the portrait was created.Desktop Version
Once upon a midafternoon dreary…
Once upon a midafternoon dreary…
To the superstitiously inclined, this flock of ravens—pictured battling a snowstorm in Finland—is nothing short of a bad omen, while to others it"s just a bunch of beaks. Likewise, today is just another flip of the calendar to some, while Friday the 13th consigns others to a day of dread—or at least one of relative inactivity to avoid potential mishaps.Desktop Version
This reef is nowhere near the sea…
This reef is nowhere near the sea…
…nor the US Capitol building it"s named for. Utah"s Capitol Reef National Park—first established as a national monument this day in 1937—is named for its massive rock domes that reminded explorers of that famous rotunda back in Washington, DC. Why Capitol "Reef," though? Because the imposing formations were a major obstacle to travelers through the region, the same way a coral reef is an obstacle to sailors.Desktop Version
A wild, craggy corner of the United States
A wild, craggy corner of the United States
The sun is setting here on the west coast of Washington state"s rugged Olympic Peninsula, where more than 3,000 square miles of marine waters are protected as part of the Olympic Coast National Marine Sanctuary. Wondering where exactly we are? Look at a map of the United States and draw your finger up the West Coast until it ends where the Strait of Juan de Fuca meets the Pacific Ocean. Those final 135 miles of shoreline form the landward boundary of the sanctuary, which also extends seaward 25 to 50 miles.Desktop Version
Keep your hands inside the ride at all times…
Keep your hands inside the ride at all times…
This roller coaster at Skyline Park in Bad Wörishofen, Germany, like all other modern coasters, can trace its lineage back to the engineering work of Russian refugees living in 17th-century Portugal. To recreate the fun of sledding down snow-covered hills, the Russians built ice-bearing wooden platforms and ramps similar to very large playground slides. As the concept of the ‘Russian Mountain’ ride caught on across Europe, mechanical parts came into play, including sled-like vehicles to ride in, and rails to keep the carts on track. Over the centuries, these coaster-like rides grew to resemble the extreme, gravity-challenging thrill rides we see at modern theme parks. Where is your favorite roller coaster?Desktop Version
Polar bear capital of the world
Polar bear capital of the world
Welcome to Churchill, Manitoba, Canada, the self-proclaimed Polar Bear Capital of the World. Each year, about a thousand polar bears pass through the small town, outnumbering human residents. In October, the bears gather here to wait for the Hudson Bay to freeze over so they can venture out onto the ice to hunt for seals. The annual gathering of polar bears here is a big event for the residents of Churchill. They maintain a hotline for bear sightings and even run a polar bear "jail" that temporarily holds "pesky" bears to keep locals (and their food) safe.Desktop Version
Dancing waters of Dubai
Dancing waters of Dubai
With the 2009 opening of the Dubai Fountain, featured in today"s image, the city of Dubai claimed another record for the books—"world"s tallest performing fountain.’ It"s located appropriately enough at the foot of the Burj Khalifa, currently the world"s tallest building. Designed by the same company that created the fountains at the Bellagio Hotel in Las Vegas, everything about the Dubai Fountain is impressive. Over 900 feet long and located in the 30-acre Burj Lake, the fountain has more than 6,600 lights and 75 color projectors. These are used to create over 1,000 different "water expressions" and provide a rainbow of colors, all perfectly choreographed to a carefully crafted musical playlist.Desktop Version
On this shore, history was made
On this shore, history was made
As the sun sets on a beach in Normandy, France, what appear to be working barges and boats offshore are actually the remnants of a Mulberry harbour, one of the temporary portable harbors created by the Allies during World War II. Their story began 77 years ago today, on D-Day, when the first of the Allied troops touched down on the Nazi-occupied beaches at Normandy. After the Allies successfully held the beachheads, the Mulberries were towed into place so the artificial harbors could provide the port facilities necessary to offload the thousands of men and vehicles, and tons of supplies necessary to sustain the effort to drive the Germans out of France.Desktop Version
Fibonacci Day
Fibonacci Day
It"s a bit of a fib that Fibonacci, the 13th-century Italian math whiz, was the first to sketch out a number sequence in which each number is the sum of the two preceding numbers: 0, 1, 1, 2, 3, 5, 8, 13, and so on forever. In fact, scholars in India described the sequence centuries before Fibonacci, and they probably weren"t the first to figure it out either. But in any case, each November 23—that is, 11/23—we celebrate the infinite series known as the Fibonacci sequence.Desktop Version
