Infinity Day
Infinity Day
This looping highway in Taipei bears a resemblance to the symbol of infinity—the concept of something without ends or limits that is celebrated today. Infinity Day is held on the eighth day of the eighth month, a nod to the symbol"s likeness to a sideways figure-of-eight. Established in 1987 by a New York-based philosopher, Jean-Pierre Ady Fenyo, the day celebrates freedom of thinking in its various forms, from philosophy through the arts and sciences. The symbol itself has a much longer history. English mathematician John Wallis is credited with introducing it as a mathematical symbol in 1655. The philosophical concept of infinity dates back at least as far as ancient Greece.Desktop Version
Wildebeests in Maasai Mara, Kenya
Wildebeests in Maasai Mara, Kenya
Welcome to Kenya"s Maasai Mara National Reserve, where some of its most iconic inhabitants are out for an evening stroll. Wildebeests, also known as gnus, are social animals which often form large herds. There are two types: black wildebeests and blue wildebeests and it is the latter which take part in the famous Great Migration, one of the world"s greatest wildlife spectacles.Desktop Version
Walk the line
Walk the line
Our homepage today shows two climbers slacklining between boulders near Bishop, California. Look closely and you’ll see something very similar to tightrope walking: The slackliners anchor a thin strip of webbing between two points and then walk across (very carefully, of course). Bishop is near the Sierra Nevada and is a popular destination for climbers interested in both slacklining and bouldering. What"s bouldering? That"s rock climbing without ropes or harnesses. Instead, climbers simply shimmy up rocky crags and free-standing boulders—but no higher than 20 feet, for safety’s sake. And where there are rock climbers, you’ll likely find slackliners.Desktop Version
National Pearl Harbor Remembrance Day
National Pearl Harbor Remembrance Day
While most know the US entered World War II after the Japanese bombed Pearl Harbor, fewer know that the battle on December 7, 1941, actually started here on Oahu"s eastern shore at the old Kaneohe Bay Naval Air Station. Now a Marine Corps airfield, the base lies beyond the small, cone-shaped Mokoli"I Island in the background of this image.Desktop Version
Mount Sopris, Colorado
Mount Sopris, Colorado
The rising sun hits the twin peaks of Mount Sopris in this autumnal scene, in Colorado"s Elk Mountains, in the Rockies. Known as East Sopris and West Sopris, the two summits are both 12,965 feet in elevation, towering over the town of Carbondale, in the Roaring Fork Valley. It"s a common misconception that Mount Sopris was a volcano but, although magma built up beneath its surface, it never erupted. Instead, it crystallized about 10,000 feet beneath the Earth"s surface, creating a massive rock-covered dome. Erosion by rain, melting snow and glacial ice then shaped it into this twin-peaked giant over tens of millions of years.Desktop Version
Rosa Parks Day
Rosa Parks Day
On Dec 1, 1955, Alabama native Rosa Parks took a stand when she refused to stand. Parks rejected bus driver James F. Blake"s order to vacate a seat on a Mongomery bus in favor of a white passenger and was arrested and fined for this act of civil disobedience. Parks then helped lead a boycott of Montgomery buses that lasted for over a year. The year-long protest finally ended when the US Supreme Court ruled that Alabama’s laws enforcing segregation on city buses and other modes of transportation were unconstitutional.Desktop Version
Eurasian lynx
Eurasian lynx
Ready for a next-level staring contest? Don’t worry, you"re unlikely to come face to face with a Eurasian lynx like this one, padding through the snow on our homepage. This elusive predator prowls around the forests of northern Europe and Siberia and the hills and mountains of Central Asia, often unnoticed by humans. Their low calls can be heard by other lynx, and they are primarily active at night, dawn, and dusk, although they can hunt by day if needed. These solitary hunters have keen senses and remarkable agility, able to climb trees and jump more than 6 feet straight up to catch prey. In temperate forests, they mainly dine out on rabbits, hares, marmots, and other small mammals, although they can take on prey as large as deer.Desktop Version
World Wildlife Day
World Wildlife Day
Today is World Wildlife Day, the UN-sponsored tribute to efforts that protect the plants and animals that make our world so special. This year"s WWD theme is "recovering key species for ecosystem restoration"—key species like the greater one-horned rhinoceroses you see here in northeastern India"s Kaziranga National Park. These unique creatures have staged a remarkable comeback from the verge of extinction in the early 20th century, when their numbers had dwindled to a precarious low of around 100 animals. But with the concerted efforts of Indian and Nepalese wildlife authorities, the population of greater one-horned rhinos has slowly built back up to around 3,700 today.Desktop Version
Belted Galloway cows
Belted Galloway cows
These cool cows are Belted Galloways, also known as "Oreo cows." (And if you like a glass of milk with your cookies…) The heritage breed originated in the southwest of Scotland, and it thrives on the region"s rough pastures and windswept slopes. Belted Galloways fight the elements with a double-layer coat: The long, coarse hair diverts rain, and beneath that, the cow has a soft undercoat to keep it warm and dry in the harsh Scottish winters.Desktop Version
Folegandros Island, Cyclades, Greece
Folegandros Island, Cyclades, Greece
Welcome to Folegandros, one of the Greek Cyclades Islands in the Aegean Sea. This picturesque island has changed hands several times during its long history. It is thought it was once home to the Dorians, one of the four major ethnic groups of classical Greece, but it was also ruled for centuries by the Republic of Venice and later the Ottoman Empire. Greece reclaimed it in 1828.Desktop Version
Horseshoe Bend, Arizona
Horseshoe Bend, Arizona
Grab your boots and gear, today we"re heading to Arizona to hike out to Horseshoe Bend. Known as the "east rim of the Grand Canyon," it"s actually about 140 miles from the other rims and is really more a part of nearby Glen Canyon. Scientifically, the beautiful view exists thanks to something called an "entrenched meander." Around 6 million years ago, the area was closer to sea level. The Colorado River, following the path of least resistance, meandered and became trapped when the Colorado Plateau uplifted around 5 million years ago. Over time, the river water cut through exposed sandstone, forming the thousand-foot-deep, 270-degree horseshoe-shaped bend.Desktop Version
Bukhansan National Park, South Korea
Bukhansan National Park, South Korea
Just a few miles north of South Korea"s capital city of Seoul, Bukhansan National Park is a retreat for city dwellers and international visitors. Forests and ancient temples sit side-by-side in the park, beneath the three granite peaks of Bukhan Mountain, or Bukhansan. Among the park"s ridges and valleys, water deer, wild boar, chipmunks, and squirrels roam freely. A careful ear might pick out the rat-a-tat of woodpeckers or the chirpy melody of songbirds perched in the trees. The park also boasts Bukhansanseong Fortress, whose current structure was completed in 1711.Desktop Version
Northern coast of Colombia
Northern coast of Colombia
Colombia is the only country in South America that has coastline on both the Caribbean Sea and the Pacific Ocean. Seen here is a stretch of beach near Parque Nacional Natural Tayrona and the small town of Buritaca, on the Caribbean coast along Colombia’s north shore. This region boasts some of the most beautiful beaches in the country. It"s also among Colombia"s most ecologically diverse areas, with jungle, desert, and one of the highest coastal mountain ranges in the world, the Sierra Nevada de Santa Marta.Desktop Version
Siblings Day
Siblings Day
Make the most of this family photo—caracals tend to go solo as adults, so these cute cubs will hang out together only until they"ve honed their hunting skills from watching mom. In the meantime, we think they make ideal mascots for Siblings Day, celebrated in the US and Canada on April 10.Desktop Version
International Nurses Day
International Nurses Day
While the uniform style has changed since these American Red Cross nurses proudly posed together in Paris, France, in 1919, the medical care and kindness provided by nurses the world over has remained steadfast. Today we"re celebrating International Nurses Day, which is observed on May 12 each year to turn a well-deserved spotlight on nurses and the contributions they make to society. The theme for 2022"s observance is "Nurses: A voice to lead—Invest in nursing and respect rights to secure global health." It"s a fitting topic, especially when nurses have borne the brunt of the COVID-19 pandemic. For more than two years, nurses have suffered from critical staffing shortages while facing a health crisis of tremendous proportions. For all that nurses have endured and for all they"ve contributed to our personal and collective well-being, we offer our heartfelt thanks.Desktop Version
San Blas Islands, Panama
San Blas Islands, Panama
Nestled off the northern coast of Panama, the San Blas Islands are an archipelago of more than 360 islands in the Caribbean Sea. Known for their clean, calm waters, they are the perfect place for adventure sports such as snorkeling, surfing, and diving. Staghorn and pillar coral are among the species found in coral reefs surrounding the islands, which teem with marine life. The islands are inhabited primarily by Gunas—people indigenous to Guna Yala—who preserve their way of living with vibrant, traditional clothing, thatched-roof huts known as "bohíos," and intricate, handcrafted mola textiles.Desktop Version
Giving Tuesday
Giving Tuesday
The largest heron in North America, the great blue heron makes its nest in a "basket" made from twigs, usually placed high in a tree. The herons line the interior with moss, leaves, grass, and other softer materials, and tend to return to the same nesting site each year, though not the same nest. The male heron finds building materials while the female assembles the nest, then both birds maintain and add to it. The helpful male heron shown here is presenting his mate with nesting material—he seems an apt mascot for this year"s Giving Tuesday.Desktop Version
Jeju Island, South Korea
Jeju Island, South Korea
The South Korean island of Jeju is full of wonders. If you don"t have a chance to visit its volcanic landscape, ancient stone statues, waterfalls, and rocky coastline, you can dive into the island"s fascinating chronicles from the comfort of your computer. The star of today"s image, Seongsan Ilchulbong (Sunrise Peak), is the island"s rare tuff cone formation, created by an underwater volcanic eruption about 5,000 years ago. Tuff cones are also called ash cones, referring to the accumulated ash settling in a cone formation after the lava"s forceful explosion. Seongsan Ilchulbong was added to the UNESCO World Natural Heritage List in 2007.Desktop Version
Baltic Sea, Estonia
Baltic Sea, Estonia
The Baltic Sea in northeast Europe is a peculiar body of water, combining the characteristics of a sea with those of a lake and an estuary, too. Strictly speaking, it is in fact a sea and thus appropriately named, joined to the Atlantic Ocean through three straits in Denmark: the Öresund, Great Belt, and Little Belt. Technically, the Baltic is classified as a brackish sea, meaning it is not entirely fresh and not entirely saline. The Baltic Sea isn"t landlocked, but it does border many countries, including Russia, Finland, Sweden, Denmark, Germany, Poland, Lithuania, Latvia, and Estonia—and it"s the Estonian coast featured in today"s image.Desktop Version
World Migratory Bird Day
World Migratory Bird Day
The migration of birds, such as the pelicans seen here over California"s Salton Sea, is part of the pulse of our planet"s ecosystem. Around 40% of bird species migrate, typically in the fall and spring, some traveling incredible distances. Tiny hummingbirds can migrate 500 miles across the Gulf of Mexico overnight. Arctic terns fly between the Arctic and Antarctic each year, potentially racking up more than 1.5 million miles over a lifetime. The bar-tailed godwit can travel 7,000 miles in eight days, without stopping. On World Migratory Bird Day, we can help our feathered friends by protecting their habitats and taking simple steps like leaving less lights on at night, leaving out birdseed, and making windows more visible to avoid collisions.Desktop Version
Porto Timoni beach, Greece
Porto Timoni beach, Greece
Porto Timoni beach, in Corfu, Greece, is a hidden gem reached either by boat, or by hiking from the historic village of Afionas. Those who make the journey are rewarded with two stunning coves, offering a unique double-beach experience. With clear turquoise waters and dramatic cliffs, Porto Timoni presents a picturesque coastal panorama. Surrounding the beach, lush olive groves and cypress trees add to its charm. Greek islands like Corfu may seem timeless and ancient but they are relatively new in the history of Earth. A leading theory is that around 5.3 million years ago, a great flood poured in between Africa and Europe from the Atlantic Ocean, an event called the Zanclean flood. Lakes became oceans and what were previously mountaintops became islands.Desktop Version

Toledo, Spain
Toledo, Spain
Built on a hill and surrounded on three sides by the Tagus River, the Spanish city of Toledo is a UNESCO World Heritage Site packed with history. Its towering Alcázar fortress and impressive Gothic cathedral dominate the skyline, but the city is also home to mosques and synagogues. Toledo bears strong cultural influences from the Moors, who ruled here for centuries, following their arrival in Spain in 711. It was known as the City of the Three Cultures during the Middle Ages, when its Christian, Muslim, and Jewish communities coexisted harmoniously. Toledo has been the home of sword making since Roman times and is also famous for its marzipan. In the 16th century, the city was home to the famous painter El Greco, who was inspired to create some of his greatest masterpieces here.Desktop Version
