National Aviation Day
National Aviation Day
In the summer of 2016, an experimental solar-powered airplane called Solar Impulse 2 completed a 26,000-mile multi-stage trip around the world without using a single drop of jet fuel. The remarkable feat took longer than a year and made the slow-flying plane part of aviation history. We are remembering this seminal flight today to mark National Aviation Day, established in 1939 by President Franklin Roosevelt as a day to celebrate the advancement of flight. August 19 was chosen because it is the birthdate of Orville Wright, who in 1903, with his brother Wilbur Wright, became the first to achieve powered, controlled flight on the hills of Kitty Hawk on North Carolina"s Outer Banks.Desktop Version
St. Patricks Day
St. Patricks Day
Today, we"re looking out to sea from the green pastures of St Finian"s Bay in County Kerry, Ireland, to celebrate St Patrick"s Day. The country"s patron saint introduced Christianity to Ireland around the year 432, and his passing on March 17, 461, became a day of commemoration in his homeland.Desktop Version
World Bee Day
World Bee Day
It"s World Bee Day, and we"re doffing our caps in thanks to the world"s lesser known "essential workers." According to the UN, three out of four crops across the globe producing fruits or seeds for use as human food depend, at least in part, on bees and other pollinators. And tens of thousands of flowering plants, like the crocuses in today"s photo, would not exist if it weren"t for the little buzzers. A quote often misattributed to Albert Einstein suggests humans would have only four years left to live if the bees go extinct. No matter who said it, the message is clear: Our livelihood is intimately tied to the survival of bees. And that connection is of critical importance now, as bee colonies continue to struggle after more than 20 years of mass die-offs, a phenomenon known as colony collapse disorder.Desktop Version
Juneteenth
Juneteenth
Juneteenth is here, a day celebrating the freedom of enslaved African Americans shortly after the end of the Civil War. While Abraham Lincoln"s final Emancipation Proclamation in January 1863 freed slaves in Confederate states, certain areas did not abolish slavery until months after Confederate forces surrendered. Texas issued an order on June 19, 1865, that "all slaves are free." This act was the origin of Juneteenth, which combines the words June and nineteenth. However, slavery did not fully end in the US until the 13th Amendment was ratified on December 6, 1865.Desktop Version
Happy New Year!
Happy New Year!
Happy New Year"s Day! Humans have celebrated the new year since at least 2000 BCE, but various cultures have chosen different days coinciding with equinoxes or lunar cycles. The Romans established January 1 as the beginning of the year in 153 BCE, but this fell out of favor throughout Europe during the medieval era. Since 1582 and the widespread adoption of the Gregorian calendar, however, much of the world now celebrates the new year today. In addition to watching fireworks, drinking champagne, and making resolutions in the wee hours of the morning, other global traditions include making noise, eating lucky foods, and giving gifts.Desktop Version

Castilla-La Mancha, Spain
Castilla-La Mancha, Spain
In the Spanish town of Consuegra, echoes linger of the adventures of Don Quixote, the hero of Miguel de Cervantes" epic novel. This tourist destination in Castilla-La Mancha is famous for its rocky ridge, known as Cerro Calderico, crowned with 12 white windmills. The windmills are thought to have inspired Cervantes to write the famous scene in which Don Quixote mistakes them for an army of giants. With their stone walls and wooden blades, some date back to the 16th century, when they were built to grind grain.Desktop Version
Shark Awareness Day
Shark Awareness Day
For Shark Awareness Day, let"s consider things from the shark"s point of view. Sharks get a bad rap. They may be apex predators of the oceans, but we"re the ones most responsible for reducing their populations by more than 70% in the past half-century. Rather than perpetuate the stereotype of sharks being dangerous, let"s think of them as they are—amazing sea creatures with hundreds of millions of years of history in their genes. We may not always want to encounter them face to face, but they deserve our respect and for the health of our oceans as whole, sharks deserve protection.Desktop Version

Apple Tree Day
Apple Tree Day
Apple Tree Day is a nationwide ode to the art of apple cultivation and the health benefits this beloved fruit brings to our lives. Apples made their way to North America with European colonists in the 17th century. In 1625, the first apple orchard in North America was planted in Boston by William Blaxton. Today, from Red Delicious to Honeycrisp to Pink Lady, some 200 varieties are grown in the US. The chaffinch on our homepage today is pictured amid tiny crab apples. Sure, they can be a bit tart, but they make for a lovely display in winter and some birds depend on them when other food is scarce. Sliced, baked, in a salad, or as cider, how do you like them apples?Desktop Version

Badlands National Park turns 44
Badlands National Park turns 44
Forty-four years ago today, a rugged, inhospitable area of South Dakota was designated a national park to protect the many fossils found there. The region has a 12,000-year history as hunting grounds for Native Americans. In fact, the name we know it by today, Badlands, comes from the Lakota phrase "mako sica," which literally translates to "bad lands." Covering nearly 380 square miles, its harshly eroded rock formations make it one of the most distinct landscapes in the United States.Desktop Version

Okavango Delta, Botswana
Okavango Delta, Botswana
At a glance, this might look like some ordinary swamp, but the Okavango Delta in the African nation of Botswana is a veritable miracle of nature. Unlike most rivers, the Okavango River doesn"t drain into any sea or ocean, but rather empties into the open savanna. Thousands of elephants, and just about every other type of African animal you can name, owe their existence to this annual wetland. "Annual," because the marshland of the delta swells threefold to its full size but once a year, between March and July, when the seasonal rains from the highlands of Angola flow downhill 750 miles until they flood the arid savanna of northwest Botswana. The wildlife drawn to this life-sustaining water includes lions, leopards, cheetahs, rhinos, giraffes, zebras, hippos, wildebeests, hyenas, crocodiles, impalas, and of course elephants, the planet"s largest land animals.Desktop Version
Brocken spectre in Central Balkan National Park, Bulgaria
Brocken spectre in Central Balkan National Park, Bulgaria
With Halloween around the corner, we present the ghostly image of a Brocken spectre. Despite appearances and the season, there"s nothing paranormal about a Brocken spectre. It"s the magnified shadow of an observer cast in midair upon a cloud opposite a strong light source. Brocken spectres are rare but climb a mountain at dawn up to the misty slopes and you may be fortunate enough to witness the effect. The spectre, also known as a Brocken bow, mountain spectre, or spectre of the Brocken, can appear anywhere in which conditions are right—like here in the Balkans of Bulgaria. But it"s the thick fogs of the Brocken, a peak in the Harz Mountains in Germany, from which the phenomenon draws its name.Desktop Version

Native American Heritage Day
Native American Heritage Day
Today we mark Native American Heritage Day and Month with the imposing pyramid now known as Monks Mound, once the center of a city that rivaled any European city of the age in population. Built by people of the Mississippian culture, construction of Monks Mound began early in the 900s CE in present day southern Illinois. By around 1050 the area had grown into a major hub of commerce and agriculture now known as Cahokia. With a population that may have exceeded 40,000 at its peak, Cahokia was the largest urban center north of the great Mesoamerican cities of Mexico and Central America. In the 13th century, for reasons still debated by scholars, the city began to decline, and it was abandoned around 1350. Excavations in the 19th and 20th century revealed a society far more sophisticated and complex than many had believed existed north of Mesoamerica previously.Desktop Version
Polar Bear Week
Polar Bear Week
The largest carnivore on land roams the icy north. Polar bears like this one spend much of their lives on sea ice rather than terra firma, stalking their favorite prey: seals. Superbly insulated against the cold, polar bears are uniquely suited for life on the ice—so they"re especially vulnerable to a warming planet. Their plight is the focus of Polar Bear Week, observed the first week of every November, bringing attention to these creatures who live far out of sight of most humans.Desktop Version
