Why, aloe there
Why, aloe there
Aloe isn"t just that itch-relief ooze you buy at the supermarket. Aloes are some of the most splendid succulent plants in nature, coming in many shapes and colors. While the rubbery, gel-filled leaves of most aloe plants are long and spear-shaped, those of the pictured Aloe polyphylla species are stout and tightly set—one of many examples in nature of a near-perfect spiral. Commonly called spiral aloe, it"s a coveted garden plant with specific growing conditions that make it hard to keep alive. Even in nature it"s rare and native only to the chilly mountains of Lesotho, a tiny kingdom entirely surrounded by South Africa.Desktop Version
Land ho in New Zealand 250 years ago
Land ho in New Zealand 250 years ago
On October 6, 1769—250 years ago today—Captain James Cook reached New Zealand on his first voyage to the Pacific. He would eventually map the entire New Zealand coastline, including the area here at Marlborough Sounds, a network of ancient sunken river valleys on New Zealand"s South Island. The main purpose of Cook"s voyage to the Pacific was to sail to Tahiti and observe the transit of Venus across the face of the sun. Only after completing this task did Cook unseal the rest of his orders and learn he was to search the South Pacific for signs of a fabled great southern continent, Terra Australis Incognito. European Renaissance geographers believed this hypothetical southern landmass must exist in order to counterbalance the Northern and Southern Hemispheres.Desktop Version
Bridge to infinity
Bridge to infinity
Infinity Day has us visiting Perth, Australia, and the Elizabeth Quay Bridge. From this aerial view, the bridge closely resembles a tilted ∞, the common symbol for infinity first popularized in a 17th-century mathematical text. We recognize this unofficial holiday every August 8, because the number 8 resembles the infinity symbol—at least when tipped on its side—and the eighth day of the eighth month is an infinitely superior day to celebrate the infinite.Desktop Version
And you thought moths were boring
And you thought moths were boring
National Moth Week shines the porch light on an 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, take a gander at winged wonders like the comet moth, shown here. Scientists estimate that there are some 160,000 species of moths worldwide, many just as stunning as our comet moth, and tracking their health often helps us gauge the health of entire ecosystems.Desktop Version
Aw shucks, it’s oyster season in Galway
Aw shucks, it’s oyster season in Galway
When you think of Ireland, do you think of oysters? The proud oyster farmers here in Galway Bay think you should. This weekend, fans of the bivalve have poured into the Galway International Oyster and Seafood Festival, an event that claims to be the oldest oyster festival in the world--and the most recognized Irish festival outside of St. Patrick’s Day. Visit Galway yourself and you can sample the native oysters, which have been harvested here for centuries, and also try the Pacific varieties that were brought in during the 1970s. Fans of native Galway oysters tout their meaty texture and subtle flavor. They pair well with Guinness, we presume.Desktop Version
Fog above the forest
Fog above the forest
Today we"re looking out over Pisgah National Forest, which was established on this day in 1916. One of the first national forests established in the eastern United States, it comprises more than 500,000 acres of mountainous peaks, cascading waterfalls, and heavily forested slopes. With hundreds of miles of trails, Pisgah is a popular place for hiking, backpacking, road biking, mountain biking, fishing, and rock climbing.Desktop Version
Does this shark have an Irish accent?
Does this shark have an Irish accent?
Our Shark Awareness Day celebrity is a blue shark swimming in the cold waters off Cork, Ireland. The inspiration for its name comes from the blue shark’s back color, not its mood. It’s currently listed as ‘near threatened’—a status all too common for sharks today. Why celebrate an apex predator that most humans associate with horror movies? Because without sharks acting as population control on other marine life, the world’s oceans would be a very different place. Blue sharks eat a lot of squid and fish, and like land predators, help to keep their prey from overpopulation. Mother Nature keeps us in a delicate balance, so it’s important that we don’t accidentally remove a vital member of that system… even if that creature seems scary to most of us.Desktop Version
The Grand Départ: Tour de France begins
The Grand Départ: Tour de France begins
All eyes are on France today as 22 teams begin the 105th Tour de France, the prestigious cycling race that takes competitors more than 2,000 miles through the countryside. Our image show the peloton (the main pack of riders) racing down a tree-lined road from Montélimar to the Parc des Oiseaux in Villars-les-Dombes during Stage 14 of the Tour de France in 2016. If you’re new to the competition, here’s what you need to know: The race includes 21 stages that span 22 days. Competitors will climb at grades of up to 11 percent through the Alps and Pyrenees, and pedal over miles of cobblestone and dirt roads, country lanes and highways, at last coming to a finish at the Champs-Élysées in Paris. When you see the peloton, keep an eye out for the yellow jersey–at each stage it’s worn by the cyclist with the overall leading time and is ultimately awarded to the winner. Bonne chance, riders!Desktop Version
Panda Day
Panda Day
There"s just something comforting about giant pandas. They"re stoic but look cuddly, and their unusual black and white markings make them distinctive. Pandas are one of the animals we recognize from an early age. But while we may take them for granted, they"ve been under threat from shrinking habitats and food supply as people harvest bamboo and build roads and train tracks through their forests. National Panda Day on March 16 spreads awareness about these beloved bears and encourages us to safeguard their future.Desktop Version
It s leap day!
It s leap day!
For leap day (the extra day added to February every four years), we"re looking at a Wallace"s flying frog. Also known as parachute frogs, these critters live in the tropical jungles of Malaysia and Borneo. They spend most of their time in trees, gliding down to the ground to mate and lay eggs. They "fly" by leaping and using their webbed fingers and toes to glide as far as 50 feet.Desktop Version
Computer Science EDU Week
Computer Science EDU Week
In the decidedly pre-digital 19th century, English polymath Charles Babbage developed his design for an Analytical Engine, a machine that incorporates many of the functional ideas of modern computers. The diagram in our photo today shows the plans for the inner workings of Babbage"s mechanical computer. Construction was difficult and expensive, given the precision required for the crafted metal parts, so Babbage tinkered on his own but died before he saw his vision realized. Engineers have since built working models of Babbage"s machine.Desktop Version

Peel Castle on St. Patrick’s Isle with the Isle of Man in the background
The Isle of Man has a long and complicated history of invasions, conquests, and systems of government. Pictured on today’s homepage are the ruins of the cathedral on the grounds of Peel Castle, on St. Patrick’s Isle (which is connected by a causeway to the rest of the island). Vikings built the original wooden fortification during the 11th century on a location that had older Celtic monastic structures made of stone, which were incorporated into the castle. Over the next eight centuries, the various Norse, Scottish, and English rulers of the area added battlements, towers, and the cathedral to the grounds.Desktop Version

Hey, who’s in charge here?
Hey, who’s in charge here?
On Boss’s Day, we’re showcasing a working relationship with unusual power dynamics. The oxpecker bird and the African buffalo, while of starkly different sizes, make a good team. The oxpecker feeds exclusively while perched on the buffalo’s body, removing bothersome parasites and bugs while getting a steady supply of food for itself. Some scientists believe this to be an example of a symbiotic relationship, but others think the oxpecker behaves more like a parasite. Ah, office politics.Desktop Version
Racers pushing past sunflowers in the 2018 Tour de France
Racers pushing past sunflowers in the 2018 Tour de France
Cyclists have been competing in this prestigious, multi-stage race since 1903. The route is changed every year but always includes a mix of terrains and elevations, mostly in France. Originally conceived as a promotion for a newspaper, the Tour is now a worldwide sporting event that draws billions of viewers each year, making it more popular than the Super Bowl. Here, competitors are biking alongside the summertime sunflowers of southern France that are in full bloom during the race. This scenic image is a foil to the grueling duration of the race, which covers more than 2,000 miles over a 23-day span. Although athletes are organized into teams, the individual who completes the strenuous course in the overall shortest amount of time wins and gets a cash prize often shared with teammates. This year’s race starts in Belgium and will pedal past the iconic sunflowers around stage 16 before coming to a stop in Paris.Desktop Version
Mardi Gras flower power
Mardi Gras flower power
While the purple flowers and green ironwork may not look overly festive to the untrained eye, residents of New Orleans will no doubt spot the significance of both, especially today, on Mardi Gras, the final day of Carnival. Purple and green are two of the three official colors of Mardi Gras, together with gold, and in a normal year the streets would be full of revelers decked out in all three colors as they dance and parade down the streets of the city. Due to COVID-19, there won"t be any parades this year, but the colors will still be on full display in the city"s famous French Quarter and elsewhere, including as colorful icing atop king cakes, a beloved treat that"s associated with the Carnival season.Desktop Version
Hot and Spicy Food Day
Hot and Spicy Food Day
The super-spicy curries of Bangladeshi cuisine start out here in the chili fields, where workers harvest and sort red chili peppers by hand. Once picked, the peppers are sun-dried and used whole or ground into powder. The chilis not only add a flavorful kick to foods but help kill bacteria as well. Plus, spicy foods help diners cool down: One natural reaction to capsaicin, the active chemical in chilis, is sweating, which can help chill the skin amid tropical heat.Desktop Version

Is that a face in the sand?
Though the coastal Namib Desert begins in the southwest of Angola, and creeps into South Africa, the largest stretch of the Namib makes up the coastline of Namibia. Parts of the Namib rise in steep elevation, while the northern portion is often shrouded in thick fog rolling off the Atlantic. The fog over the region called the Skeleton Coast is responsible for numerous shipwrecks, but the moisture it brings into the harsh desert landscape is crucial to the flora and fauna that thrive here.Desktop Version
Happy World Meteorological Day
Happy World Meteorological Day
On this World Meteorological Day, celebrated each year on March 23, we climb far above the Earth for a view of the southern Peruvian coast courtesy of the Landsat 8 satellite. Below the clouds, at the bottom of those canyons, are the Yauca and Acarí Rivers, which drain into the Pacific. As any good meteorologist taking a break from today’s celebrations will tell you, warm air from the equator forms a layer over the cool coastal air here, pushing the clouds into the deep river canyons and covering the Pacific Ocean shore.Desktop Version
Hohenzollern Castle near Stuttgart, Germany
Hohenzollern Castle near Stuttgart, Germany
For the charming Hohenzollern Castle, the third time really was the charm. Constructed on the top of Hohenzollern Mountain in the 11th century, the castle was largely ruined by a 10-month siege in 1423, only to be rebuilt a few decades later. It then served as an important strategic stronghold before again falling into disrepair. In the 19th century, King Frederick William IV of Prussia, best remembered for his commitment to building great works across Germany, had a new castle built on the grounds, replacing almost all the 15th-century construction. Today, Hohenzollern Castle is an open-air museum that hosts more than 350,000 visitors per year, making it one of the most-visited castles in Germany.Desktop Version

Fall comes to the Last Frontier
Join us in celebrating Alaska Day here at beautiful Mendenhall Lake, just a stone’s throw from the state capital of Juneau. It seems a timeless sight, but the lake actually began to form in the early 1900s as Mendenhall Glacier receded, leaving a deeply carved valley in its wake that was soon filled with glacial melt. Today, the glacier still feeds the lake, much to the delight of the many visitors who arrive in Juneau each summer on cruise ships.Desktop Version

It’s Canada’s national day
For Canada Day, we’re dipping our paddles in Still Creek, a long gentle stream in British Columbia. The canoe has long been associated with Canada’s national history, linked with early explorers, fur traders, and colonists who ventured out into the wilderness of the great north. An image of a canoe even appeared on early versions of Canada’s silver dollar, a coin which was later replaced by the ‘loonie,’ so named for the depiction of a common loon on one side.Desktop Version

Fantasizing about warm, sandy beaches with gently lapping waves? Well, we decided you could use a shake-up—so here we are on California"s Monterey Peninsula for a glimpse at the ocean"s raw, unadulterated power. Asilomar State Beach"s mile-long coastline trail offers views like this one of seas crashing on jagged shores. Below the frothy surface swim innumerable ocean organisms protected by the massive Monterey Bay National Marine Sanctuary, the largest marine preserve in the contiguous United States. Behind us, a rich dune habitat supporting its own delicate flora and fauna can be explored via a boardwalk trail.Desktop Version
The moth wonderful time of the year
The moth wonderful time of the year
You"re forgiven if this is the first you"re hearing of National Moth Week, even though it"s been going strong for eight years as a global call to learn about and observe the fuzzy little insects. All too often dismissed as pesky, drab counterparts to our brightly fluttering friends the butterflies, moths seem to hog every light but the spotlight. But they don"t need flashy marketing to win the numbers game: With an estimated 160,000 moth species (though some estimates go up to half a million), they vastly outnumber their swaggering butterfly cousins in the Lepidoptera order.Desktop Version
