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
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
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
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
Lavender fields on the Valensole Plateau in Provence, France
Lavender fields on the Valensole Plateau in Provence, France
We"re sorry. The scratch "n" sniff option was not ready in time for this photo, so you"ll have to imagine the intoxicating fragrance wafting over you... Today we"re in the lavender fields that carpet the Valensole Plateau in Provence, France. A rolling 300 square miles of flowers color the landscape as far as the eye can see. Vincent van Gogh spent time here, and featured lavender in some of his paintings. June is the start of the lavender season, and though it runs till August, peak viewing (and smelling) time varies a little with fluctuations in temperature and rainfall. There are lovely villages that you can meander while visiting the lavender fields, stopping for a pastry or crunchy-soft baguette at an outdoor cafe.Desktop Version
Jackie Robinson Day
Jackie Robinson Day
On April 15, 1947, more than 26,000 spectators at Brooklyn"s Ebbets Field witnessed history as Jackie Robinson became the first Black player on a modern-era major league baseball team. (Three Black players played in the major leagues briefly in the 19th century before the color line was fully established.) Robinson endured racist resistance throughout his first season with the Brooklyn Dodgers, but the national pastime"s color barrier was broken, and other players followed him within months. In 1997, Major League Baseball retired Robinson"s number, 42, across all teams, and in 2004 it began the annual April 15 observance of Jackie Robinson Day. This photo shows Robinson signing autographs for fans at spring training in the Dominican Republic the year after his debut.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
Uncommon clouds are gathering
Uncommon clouds are gathering
A satellite view of the Mania River in Madagascar allows us to see a curious cloud pattern. It"s common for cool, moist marine air to rise and form dense clouds over bodies of water, then for the clouds to evaporate as they drift over warmer, drier land. The opposite is happening here: Puffs of clouds are forming over land, but not over water. That"s because Madagascar"s tropical rainforests are warm and wet enough that evaporating moisture rises as the day heats up. When it rises high enough, the moisture encounters cooler air, which condenses the water into clouds. Generally speaking, clouds will form where the air is rising, which in this case is only over the land. Above the river, the air is cooler and descending, so no clouds are forming there.Desktop Version
Ice and Snow Sailing World Championships
Ice and Snow Sailing World Championships
Today is the opening day of the WISSA Ice and Snow Sailing World Championships, which take place this year in Lithuania. Iceboating, also known as ice sailing, began in 17th-century Europe. Travelers used vessels on blades to traverse the frozen Gulf of Riga in the Baltic Sea and the iced-over canals of the Netherlands. These days, the sport is enjoyed as a recreational and competitive activity using a variety of boats, boards, skates, and kites. The world championships, which fall under the broader umbrella of windsurfing competitions, have been held since 1980. Good luck to all those out there competing for fame and glory on the windswept ice!Desktop Version
World Space Week begins
World Space Week begins
For the start of World Space Week, today"s homepage features a composite of images taken by NASA"s Juno probe as it swooped past Jupiter. The largest planet in our solar system, Jupiter also has the largest number of moons: 79. Jupiter is the Roman counterpart to Zeus, and the planet"s major moons are named after Zeus", shall we say, extra-marital partners. So, when it came time to name NASA"s most ambitious Jupiter probe, they decided to name it after Jupiter’s wife, Juno, so that she could keep an eye on him. Every 53 days in the course of its wide and complex orbit, the Juno probe makes its closest approach, snapping shots like these as it speeds past the gas giant in just two hours. World Space Week starts on the anniversary of the launch of the very first space probe, Sputnik, which entered orbit around the Earth on October 4, 1957.Desktop Version

Illuminating Annecy
Who knew that an 800-year-old structure could look so festive? The pretty holiday illumination you see is adorning the side of the Palais de l"Ile, a distinctive 12th-century building in the town of Annecy, France, high in the French Alps. Designated a historic monument in 1900, the medieval structure is perched on a small islet in the Canal du Thiou.Desktop Version
Glacier cave in Iceland
Glacier cave in Iceland
The Land of Fire and Ice is home to countless natural wonders, like this brilliant blue cave formed within the ice of a glacier. (Glacier caves are often called ice caves, but the term "ice cave" is properly used to describe a bedrock cave that contains year-round ice; a glacier cave is formed entirely within the ice of a glacier.) The majority of Iceland"s glacier caves are in Vatnajökull glacier, which covers about 8% of the island nation and is one of the largest glaciers in Europe.Desktop Version

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
Mount Hood, Oregon
Mount Hood, Oregon
Mount Hood graces Oregon"s skyline with a pointed, snow-capped peak. At nearly 11,250 feet high, this dormant stratovolcano is the tallest mountain in the state, drawing adventurers and nature aficionados alike. With 12 named glaciers and numerous snow fields, Mount Hood offers a wintry playground all year round. It also nurtures ancient forests and provides a haven for wildlife, including cougars and wolves. Over the past 1,800 years, the volcano has erupted three times. While considered dormant, there is still a chance that it could erupt one day.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 Christmas Bird Count begins
The Christmas Bird Count begins
Today marks the start of the annual Christmas Bird Count, a bird census sponsored by the National Audubon Society that also happens to be the longest-running citizen scientist survey in the world. Each year the count runs from December 14 to January 5, giving bird lovers across North America a chance to join in, get outside, and spot some birds. The findings recorded by participants are collected and used to gauge the health of various bird populations. This information is then used to focus conservation efforts on particular species and geographical areas.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
International Polar Bear Day
International Polar Bear Day
February 27 marks International Polar Bear Day—an effort to raise awareness of the enormous threats polar bears face due to climate change. Polar bears need Arctic pack ice to hunt on, but that ice is shrinking as the planet warms. While polar bears are excellent swimmers—so much so that they"re classified as marine mammals—the Arctic ice is still a crucial part of their survival. Let"s take this day to think about what we can do to help reduce climate change and protect polar bear habitats.Desktop Version
Rumelihisarı in Istanbul, Türkiye
Rumelihisarı in Istanbul, Türkiye
Though Türkiye usually lives up to expectations as a warm Mediterranean country, snow occasionally falls here. This winter dusting of Istanbul, Türkiye"s largest city, brings into sharper focus the lines of Rumelihisarı in the center of our image. The structure, also known as Rumeli Fortress, was built in the 15th century by an Ottoman sultan as a way to choke naval traffic through the narrow Bosporus Strait. The Bosporus connects the Sea of Marmara to the Black Sea, separating Istanbul into what are often referred to as its "European side" and "Asian side." Today, the fortress isn"t used to fire upon ships but serves as a museum and concert venue. While the place has changed over the centuries, the killer view hasn"t.Desktop Version

Jöriseen lakes in the Silvretta Alps, Switzerland
Today we"re exploring a place of otherworldly beauty: the Jöriseen, a group of alpine lakes near Davos, Switzerland. On sunny days, the lakes glow an ethereal blue, contrasting with the dark, jagged Silvretta Alps that encircle them. The sunlight is reflected in the water by "rock flour"—silt-sized rock particles generated from the grinding of bedrock by glaciers.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
Spring awakens
Spring awakens
No flower better signals the start of spring than crocuses, early bloomers that come in Easter egg colors such as purple, lavender, orange, pink, and yellow. Crocuses are perennial, flowering bulbs that are built for toughness. As you can see, the plants are able to endure frost and even snow because their flowers and leaves are protected by a waxy cuticle. That"s why the first blooms you see in spring are often crocuses. They can grow in a variety of environments, even in the high elevations of the alpine tundra above the tree line.Desktop Version
