Taking the scenic route to Sturgis
Taking the scenic route to Sturgis
South Dakota’s scenic highways roar to life this week as hundreds of thousands of bikers from around the world arrive for the annual Sturgis Motorcycle Rally. The small town of Sturgis, population roughly 7,000, swells to a gathering of half a million for this event, which includes 10 days of races, concerts, and revelry. The Sturgis rally was founded in 1938 by the Jackpine Gypsies Motorcycle Club and Sturgis resident Clarence ‘Pappy’ Hoel–a legend in these parts. What started as a modest gathering of just nine riders is now one of the largest rallies in the world.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
In celebration of America’s national bird
In celebration of America’s national bird
June 20 is American Eagle Day, a celebration that commemorates the date in 1782 when the bird was added to the Great Seal of the United States, effectively becoming a national symbol. With an olive branch in its right talons and a bundle of 13 arrows in its left (representing the 13 original states in the Union), the eagle is said to represent a strong desire for peace, but readiness for conflict. You’ll likely recognize the Great Seal of the United States from its appearance on passports, flags, official documents, and American currency. The bald eagle, now federally protected, continues to inspire national pride.Desktop Version
Lizard of mystery
Lizard of mystery
The curious case of the Ecuadorian horned anole has fascinated herpetologists, making it an excellent mascot for World Lizard Day. Its story starts in 1953, when a single male specimen of the species was discovered near the Ecuadorian town of Mindo. Over the next 13 years, only a handful of additional Ecuadorian horned anoles were found, all males, and each sporting the same long snout that earned its species the nickname ‘Pinocchio lizard.’ So rare and secretive is this anole, that for the next four decades no more individuals were found, and scientists feared the Pinocchio lizard had gone extinct. It wasn’t spotted again until 2004, when researchers glimpsed a female for the first time. She didn’t have a long snout, leading scientists to believe the male’s sword-like appendage is primarily used in courtship (insert your own joke here).Desktop Version
Chapel on the rock
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
A goldie gala
A goldie gala
It"s ladies" night at the Great Barrier Reef: Their bright orange-pink coloration indicates these sea goldies are females. But that could change quickly: Sea goldies are protogynous hermaphrodites, meaning that when there aren"t enough fellas around, the largest females change sex to become male, turning purplish and growing even larger. All goldies are born female, but those that switch to male enjoy instantly better odds at mating time: For every male goldie there are up to 10 females.Desktop Version
Gamboa Crater, Mars
Gamboa Crater, Mars
It would be pretty tough to live on Mars. It"s cold, dry, and the conditions are harsh. The planet"s average temperature is about –81 degrees Fahrenheit, but it can get as low as –243 at the poles. But with many canyons, extinct volcanoes, and ice caps, it"s beautiful to look at from afar. Most photos of the red planet highlight its rusty color, caused by high levels of iron oxide.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

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
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
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
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
Beware the Ides of March
Beware the Ides of March
We"re at the Roman Forum for the Ides of March, a date made famous as the time of Julius Caesar"s assassination. According to the ancient historian Plutarch, Caesar had been warned by a seer that his life would be in danger no later than the Ides of March, something that William Shakespeare dramatizes in his famous tragedy of Caesar’s life and assassination. While historical fact and fiction can diverge, we do know that before March 15, 44 BCE was over, a group of senators had intercepted Caesar here in the Forum as Caesar was on his way to the Senate House. They stabbed him 23 times, killing him. Afterward, Rome descended into civil war, ending the Roman Republic, and leading to the rise of the Roman Empire.Desktop Version
Celebrating migrations
Celebrating migrations
For Canada Day, we"re peering up at "Passage migratoire" ("Migratory Passage"), an art installation of hanging woven canoes in Old Québec City. It was part of the 2016 edition of Passages Insolites (Unusual Passages), an annual public art exhibition in the historic Petit-Champlain and Saint-Roch districts of the city. The canoe has long been associated with Canada"s national history, linked with early explorers, fur traders, Indigenous peoples, and colonists who ventured out into the wilderness of the great north. The artist behind this installation, Giorgia Volpe, was inspired by "the idea of migration and its influence on the formation of our society and our territory." Canada welcomes on average about 200,000 immigrants each year, many of whom will become Canadian citizens. The migrations continue…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
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

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

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

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

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

…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
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
