World Population Day
World Population Day
On July 11, 1987, the world is thought to have welcomed its 5-billionth person. Thirty-six years later, our population has reached 8 billion and is still rising. World Population Day, established by the UN, is a day to reflect on how much life Earth can sustain, and how our lives impact our environment.Desktop Version

Festivus
For polar bears, the airing of grievances is a feat of strength in itself. These big fellas are frequent sights here in Churchill, Manitoba, where hundreds of bears converge in the winter to hunt, but we"re still calling this light-bathed snapshot a Festivus miracle!Desktop Version
Laguna de Torrevieja, Spain
Laguna de Torrevieja, Spain
When we encounter bodies of water in nature, we might expect hues of blue, from the pale cyan shade of lagoons to the navy blue of deep lakes. But pink water—where on Earth could that be found? At (deep breath) El Parque Natural de Las Lagunas de La Mata y Torrevieja in Alicante, Spain. Here, there are two lakes: one green and one pink, and it is the latter that you see on our homepage. The highly saline water, dotted with clusters of salt crystals, is the perfect environment for microscopic algae, which are rich in carotenes. This results in the rosy tinge that protects the algae from solar radiation. And the pink is just getting started, as the algae are eaten by tiny crustaceans, which turn pink and are then eaten by flamingos, which acquire the rosy hue as well.Desktop Version
When an ideal microclimate gives you lemons…
When an ideal microclimate gives you lemons…
…put them on everything. That"s the philosophy behind the two-week Lemon Festival that began yesterday and runs through March 3 in the coastal city of Menton, France, where this citrus-covered dragon looms large. This sliver of the French Riviera just down the road from Monaco almost never sees freezing temperatures, even in winter. That makes it ideal for growing lemons, oranges, and other citrus crops—and the harvests are plentiful, as proved by the Lemon Festival"s many fruit-bedecked sculptures and parade floats.Desktop Version
International Rock Day
International Rock Day
Today is International Rock Day and we"re giving due respect to these geologic wonders. It might seem odd to sing the praises of rock, but think about it. Rocks have been with humankind since the beginning. From tools to housing to weapons, they"ve been key to our survival. A period of our history was so reliant on rocks that it will be forever known as the Stone Age. We would not be where we are today without the many minerals found on our planet, so rock on!Desktop Version
World Numbat Day
World Numbat Day
OK, you might be asking: World What Day? Meet the nifty numbat! Though it"s one of many marsupials found here in Western Australia, the numbat is unique, sharing no relation to any living species. It"s also critically endangered: This cute specimen is one of fewer than 1,000 of its kind left in the wild.Desktop Version
Aprils full moon
Aprils full moon
The full moon has inspired folklore, myths, writers, and artists throughout history and has been given many names, depending on the time of year it appears. April"s first full moon is known as the pink moon, but that doesn’t mean it will appear pink against the night sky. Native Americans named it for the pink wildflowers, moss pink or creeping phlox, that bloom in the eastern US in the spring.Desktop Version
Grand finish of Le Tour
Grand finish of Le Tour
After a three-week jaunt around France, cycling"s most prestigious race concludes today with a triumphant procession into Paris before a sprint finish on the iconic Champs-Élysées. The 21st and final stage of this year"s Tour de France—the 108th edition of the famous event—begins in Chatou, a town in the western suburbs of Paris along the River Seine. Tour tradition dictates the overall race leader isn"t challenged on the last day, so it starts out as a victory parade for the champion-elect, who will be wearing a yellow jersey, posing for pictures, and sipping a glass of champagne along the route. But when the riders reach the heart of Paris, the pace picks up as they dash along the Champs-Élysées, a tree-lined promenade often described as the "most beautiful avenue in the world."Desktop Version
Work out on your way to work
Work out on your way to work
The third Friday in May is National Bike to Work Day, which encourages commuters to try biking as a healthy and safe alternative to driving. The carving we"re looking at is in Bali, Indonesia. It depicts W.O.J. Nieuwenkamp, a Dutch landscape and portrait artist who rode his bike around Bali in the early 1900s, painting as he went—essentially biking to work every day. Nieuwenkamp was the first European artist to visit Bali and was influential in introducing Balinese art to Europe. The carving is part of the Pura Meduwe Karang, one of the largest temples in Bali. The temple served as an entrance to the island in the early 20th century and contains several symbols of international influence to reflect that.Desktop Version
Fannette Island, Lake Tahoe
Fannette Island, Lake Tahoe
Tucked into a tiny bay of a grand alpine lake is this granite bump called Fannette Island, the only island in Lake Tahoe. The massive lake lies in the Sierra Nevada at an altitude of 6,225 feet, straddling the state line between California to the west and Nevada to the east with near perfect symmetry. Fannette Island is in Emerald Bay, on the California side of Tahoe"s southwest shore. A narrow inlet, seen here at the top center of this image, connects Emerald Bay to the rest of the lake, whose natural beauty draws visitors in all seasons of the year.Desktop Version
Plitvice Lakes National Park in Croatia
Plitvice Lakes National Park in Croatia
In a country more famous for its coastline, about a million visitors each year venture inland to amble along these boardwalks and marvel at spectacular lakes and mountains. Plitvice Lakes National Park is the oldest and largest of Croatia"s national parks. The big attraction is the series of 16 descending, turquoise-colored lakes, connected by subterranean karst rivers, and above ground by streams and waterfalls. The lakes are separated by natural dams of travertine, which is created by the interplay of water, plant material, and bacteria. The water changes color from green to azure to gray depending on the angle of the light and the density of minerals and organisms in the water. About 11 miles of wooden boardwalk make it easy for people to wander among the lakes, falls, and caves that are open to visitors year-round.Desktop Version
Jane’s Carousel delights
Jane’s Carousel delights
National Merry-Go-Round Day brings us to the Brooklyn waterfront, home of Jane’s Carousel, a merry-go-round that’s been delighting riders for nearly a century. Its story starts in 1922, an era of speakeasies and flappers and a booming time in carousel history, when the rides were a symbol of a community’s prosperity. Jane’s Carousel was built in Idora Park in Youngstown, Ohio, a steel city.Desktop Version
Málaga, Spain
Málaga, Spain
Today we"re visiting a city with over 2,800 years of history—it"s one of the oldest in Europe. Málaga is said to have been founded by the Phoenicians in 770 BCE and today its year-round exceptional weather has made it a center of tourism in Spain. Situated perfectly along the Costa Del Sol, this culturally rich mecca is visited by around 6 million tourists in an average year. If you can pull yourself away from the beautiful beaches, you"ll find yourself in a city abounding in historical architecture, museums, and restaurants featuring outstanding local seafood.Desktop Version
I am the walrus
I am the walrus
This herd of gentle giants is bobbing in the waters of the Svalbard archipelago, roughly midway between continental Norway and the North Pole. Walruses spend more than half their day in the water, masterfully foraging for clams and other marine organisms. The rest of the time, they hang out on ice floes, the males and females huddled separately, taking a break before diving in for more food. Walruses launch from the ice to eat, making the floating blocks an important part of their survival. With the effects of climate change increasing, Arctic ice is melting, posing an existential threat to the ancient pinnipeds.Desktop Version
Let the Highland games begin
Let the Highland games begin
Cue the bagpipes–today’s homepage brings us to Scotland for the Braemar Gathering, an annual celebration of Scottish culture that takes place today in the village of Braemar. These Highland games include traditional dance, music, and athletic competitions–and tartan, lots and lots of tartan (part of Scotland’s national dress). Since 1848, Braemar has regularly been attended by Britain’s Royal Family. Queen Elizabeth II, the official patron of the games, has come to Braemar every year since 1952, when she ascended the throne. It’s worth noting that she likes tartan too, and even has her own personal style of tartan—a pattern called the ‘Royal Stewart.’Desktop Version
International Day for Monuments and Sites
International Day for Monuments and Sites
Located high in the Andes Mountains, Peru"s Machu Picchu is believed to have been an estate for the Inca emperor Pachacuti, who ruled in the mid-15th century. This "Lost City of the Incas" is one of the world"s most famous archaeological sites, an engineering marvel, built without mortar, metal tools, or the wheel. As an icon of Inca civilization, it is a perfect fit for UNESCO"s International Day for Monuments and Sites, which has been celebrating important cultural heritage sites for 40 years. Landmarks such as the Pueblo Indian dwellings of Mesa Verde, the Taj Mahal, the Great Pyramid of Giza, and the Parthenon give us the opportunity to look back at the cultures that came before us and preserve their memory for future generations.Desktop Version
Dark Sky Week
Dark Sky Week
During International Dark Sky Week, we"re counting ourselves lucky to have this spectacular nighttime view, considering the astonishing fact that 83% of the global population lives under a light-polluted sky. Unneeded artificial light is classified as a pollutant and has been proven to have harmful side effects. Not only does it waste money and energy, it also disrupts plants and animals, is believed to impact the climate, and blocks our view of the universe.Desktop Version
Inside the Oculus
Inside the Oculus
Reconstruction after the Sept 11 attacks included not just rebuilding on the site of the Twin Towers, but replacing the transit hub station there as well. The new vision for the transit hub includes the Oculus, a building designed by Spanish architect Santiago Calatrava. A defining feature of the Oculus is a skylight at the peak of its roof, which is opened on clear days, flooding the space below with light and giving patrons a view of the new One World Trade Center building. And every Sept 11, the skylight is left open to the elements for 102 minutes—the duration of the attack on the World Trade Center. The elegant transit station is often busy with travelers making a quick stop to shop or eat, since most of the space is dedicated to retail, as it had been before the attacks on 9/11.Desktop Version
World Meteorological Day
World Meteorological Day
They might look like spaceships from a retro sci-fi movie, but these strange shapes hovering above the mountains in Patagonia are of earthly origin. These are lenticular clouds, named after their lens-like shape. They form near hills and mountains where moist air is pushed up and over the peaks, cooling as it rises and condensing into water droplets. As wind blows over the mountains it can create a series of waves in the air, and these unusual clouds form in the crest of those waves.Desktop Version
Remembering the Arizona
Remembering the Arizona
Looking up through the seven skylights of the USS Arizona Memorial, you"ll see the Stars and Stripes wave solemnly against a bright Hawaiian sky. On today"s infamous date, the flag flies at half-mast to honor the 2,403 people killed in Japan"s December 7, 1941 surprise attack on Pearl Harbor that thrust the US into World War II. Of these, 1,177 service members perished in a direct hit that blew apart the munitions-laden Arizona. Over 900 of these casualties remain buried at sea within the ship"s superstructure. They"re joined by survivors who upon their later deaths chose to have their ashes interred alongside their fallen crewmates.Desktop Version

Taking a bird"s-eye view along the coast of Italy"s bootheel, you"ll spot many coves and caves like this one, the Grotta della Poesia. In English that"s Poetry"s Cave, a sea-flooded sinkhole so named for the ancient poets who—legend has it—were charmed by a beautiful princess who often came here for a dip.Desktop Version
Yosemite National Park anniversary
Yosemite National Park anniversary
There"s a reason why famed American photographer Ansel Adams fell in love with Yosemite National Park: vistas like today"s image of Half Dome. The park, in central California"s Sierra Nevada range, has been a popular destination for artists, mountaineers, settlers, and nature lovers since the mid-1800s. To protect it from logging and overgrazing by cattle, Congress designated Yosemite a national park on this day in 1890. It"s one of the most visited parks in the US, with more than 3 million visitors a year.Desktop Version
Zion National Park turns 103
Zion National Park turns 103
Our photo brings us to a 16-mile stretch of the Virgin River where it cuts a spectacular thousand-foot-deep gorge through the upper reaches of Utah"s Zion Canyon. Flowing through Zion National Park (which turns 103 today!), the Virgin River is home to unique plants and animals that aren"t found anywhere else, due to the unique intersection of biomes found where the Colorado Plateau, Great Basin, and Mojave Desert all meet. Without the water of the Virgin River system, creatures like the woundfin minnow, one of rarest species on the planet, couldn"t exist.Desktop Version
National Mushroom Month
National Mushroom Month
Oh, to be a squirrel with a feast such as this! It"s National Mushroom Month, and it seems our red squirrel friend here in Alaska got a literal jump on celebrating. It might surprise you, but squirrels don"t only eat nuts. They"ll eat just about whatever"s around and that includes big mushrooms. Though a small percentage of wild mushrooms can be poisonous to humans, squirrels can eat many of these frightening fungi without worry, thanks to special proteins in their guts. Nice to know someone"s enjoying them.Desktop Version
