Jun 20, 2024Summer solstice

It"s that time of year again when the daylight stretches long into the evening hours. Today is the longest day of the year, known as the summer solstice, which happens when one of the Earth"s poles is most inclined toward the sun. Today"s image features the Kokino megalithic observatory, part of a wider archaeological site in North Macedonia. It is believed that it marked the position of the sun during summer and winter solstices, as well as the equinox, and consists of two platforms. A stone block on the upper platform of the observatory indicates the summer solstice sunrise direction when seen from a seat on the lower platform. This Bronze Age astronomical wonder sits more than 3,300 feet above sea level, on a hill overlooking the hamlet of Kokino.Desktop Version

Dec 12, 2024Poinsettia Day

Here"s the red poinsettia, one of the plants synonymous with the holiday season in the United States. With its striking star-shaped leaves, the poinsettia has become a symbol of Christmas cheer, brightening homes and public spaces during winter. Today, National Poinsettia Day celebrates the legacy of Joel Roberts Poinsett, the first US ambassador to Mexico, who introduced these vibrant plants to America in the 1820s. He discovered them while exploring the Taxco region in Guerrero. So taken by their beauty, he sent clippings back to his home in Charleston, South Carolina.Desktop Version

Jun 7, 2024World Oceans Day

Today, let"s embark on a watery adventure as we celebrate World Oceans Day. This day is about honoring and protecting the world"s oceans and serves as a reminder of the critical role oceans play in supporting life on Earth. These gargantuan water bodies, after all, teem with wonders, from the tiniest plankton to the grandest whales like the humpbacks we see here. The oceans also produce almost half of the oxygen on our planet thanks to the photosynthesis of plankton—tiny plants, algae, and bacteria. Moreover, they absorb a significant amount of carbon dioxide from the atmosphere, helping mitigate the impacts of climate change caused by human activities.Desktop Version

Watch closely; you might catch a glimpse of the black-naped monarch. This bird is part of the monarch flycatcher family, which also includes shrikebills, magpie-larks, and paradise flycatchers. Found across tropical southern Asia, from Iran and Sri Lanka to Indonesia and the Philippines, the black-naped monarch prefers dense forests and other lush, wooded spots. It perches upright on its short legs and spends most of its time catching insects in midair. These birds occupy the dense understory of the forest canopy.Desktop Version

Mar 24, 2025African bush elephants in Namibia

Desert elephants, found in Namibia and Mali, are African bush elephants that have adapted to the harsh conditions of the Namib and Sahara deserts. These extremely arid regions receive less than 2.75 inches of annual rainfall. Compared to other bush elephants, desert elephants have longer legs, broader feet, and slightly smaller bodies. These resilient herbivores migrate between waterholes, following ancient routes based on seasonal food and water availability. Male desert elephants often roam alone over vast areas, while female-led family groups stay near rivers, where food is more plentiful. Their incredible adaptability is showcased by their ability to travel long distances, sometimes 43 miles in a single night, to find their favorite myrrh bushes.Desktop Version

Oct 13, 2024Royal Alcázar of Seville, Spain

Today we"re stepping into the heart of the historic empire of Islamic Spain. The Royal Alcázar of Seville, in the southern region of Andalusia, stands on the site of a 10th-century citadel, which was expanded over the following 200 years. When Christian forces captured the city in 1248, this historic palace was almost totally rebuilt in the Mudejar style, which takes inspiration from the intricate patterns and decorative motifs found in Islamic architecture. Within the Alcázar, there are several courtyards lined with delicately carved columns. One of these is the Patio de las Doncellas, or Courtyard of the Maidens, pictured here today.Desktop Version

Sep 8, 2024International Literacy Day

"Literacy is a bridge from misery to hope." These words by former secretary-general of the United Nations Kofi Annan capture the essence of International Literacy Day, celebrated every September 8. Established by UNESCO in 1966, this observance not only celebrates those who can read but also highlights the ongoing battle against illiteracy. With approximately 775 million people worldwide still lacking basic literacy, this day resonates powerfully within the hallowed walls of the Stockholm Public Library in Sweden, or "Stadsbiblioteket" as it is known to locals, featured in today"s image.Desktop Version

Jun 4, 2024Chestnut-headed bee-eaters, Bardia National Park, Nepal

It"s not just a name. Chestnut-headed bee-eaters spend their days swooping after stinging insects. As well as bees, they also feast on wasps, hornets, and other bugs. The birds in today"s image are in Bardia National Park in Nepal, but they"re found across many other South Asian countries, from India and Bangladesh to Sri Lanka and Thailand. They catch their prey in mid-flight, returning to a perch where they beat insects to stun them and remove the stinger, which makes them safe to eat. These birds are designed to hunt: Their dazzling green plumage helps camouflage them in dappled jungle light, their curved beak is perfect for picking off insects with precision, and their eyes can move individually, which makes them all the better for spotting bees.Desktop Version

The tiny ruby-throated hummingbird, weighing less than a nickel, makes the trip all the way across the Gulf of Mexico. Migratory birds navigate the globe, instinctively knowing when and where to move to exploit seasonal abundance. The Arctic tern outshines them all with its intercontinental journey from pole to pole, covering roughly 25,000 miles in its annual round trip.Desktop Version

Mar 14, 2025Celebrating Pi Day

Calculating the ratio of a circle"s circumference to its diameter is as easy as pi. Today is Pi Day, an event that celebrates this mathematical constant. This date was chosen because 3, 1, and 4 are the first three significant figures of pi (π) when it is written out. Pi is an irrational number, which means that it can"t be written as a fraction. When written out, its decimal representation goes on infinitely without repeating. The oldest attempts to calculate pi date back to ancient Babylon and Egypt, around 1900 BCE.Desktop Version

Sep 19, 2024International Talk Like a Pirate Day

Ahoy, mateys! It be International Talk Like a Pirate Day. Today, landlubbers and seafarers alike put on their tricorn hats and hoist the Jolly Roger. The day started in 1995 as a joke between two friends, John Baur and Mark Summers, but it got a boost in 2002 after they shared the idea with humorist Dave Barry, who promoted it in his syndicated column. Since then, it"s become a day of fun—people don pirate costumes, engage in pirate-themed activities, like the kid on the ship in today"s image, and embrace mock pirate language. Whether ye be a seasoned buccaneer or a greenhorn, it"s time to batten down the hatches, shiver your timbers, and unleash your inner pirate. Arr!Desktop Version

Nov 23, 2024Fibonacci Day

On Fibonacci Day, mathematicians and scientists honor one of their own: Leonardo Bonacci, better known as Fibonacci. The medieval mathematician popularized the Hindu-Arabic numeral system, with its use of zero, decimal points, and 10 numbers instead of the ponderous Roman numeral system. He"s most famous, however, for his sequence of numbers: 0, 1, 1, 2, 3, 5, 8... By adding the first two numbers, you arrive at the third, and adding the previous two numbers, you arrive at the next number, and so on. Disregarding the zero, the first four numbers correspond to today"s date, 11/23.Desktop Version

Apr 29, 2024Fujian Tulou, China

Let"s step into a world of giant earthen homes designed to house a village. These "tulou" structures, built between the 12th and 20th centuries, are the dwellings of the Hakka community in China"s mountainous southeastern Fujian region. The homes are constructed from clay, sandy soil, and gray tiles, with bamboo strips serving as the support. They were built to house a whole clan, up to 800 people each. From above, these round dwellings look like giant tires or reels lying on their sides, with light walls, dark roofs, and spacious interiors.Desktop Version

Apr 21, 2025International Dark Sky Week

Imagine standing under a sky so dark that the Milky Way stretches across it like a luminous ribbon. This is the experience that International Dark Sky Week aims to bring back. Every April, during the week of the new moon (this year from April 21 to 27), we are invited to turn off our lights and gaze at the stars. The event was initiated by Jennifer Barlow, a high school student in 2003, to combat light pollution. One of the best places to experience the night sky"s beauty is Joshua Tree National Park in southeastern California, an International Dark Sky Park. Here, the absence of artificial light allows visitors to see the stars as our ancestors once did. Did you know that light pollution prevents us from seeing most of the stars in the Milky Way? By reducing it, we can reconnect with the universe"s beauty and wonder.Desktop Version

Feb 17, 2024Black History Month

As we celebrate Black History Month, we"re taking a moment to highlight an institution in the world of dance—the Alvin Ailey American Dance Theater in New York City. Founded by the visionary choreographer Alvin Ailey in 1958, it fuses elements of modern dance, ballet, jazz, and theater. The company"s performances demonstrate the importance of artistic expression in preserving and celebrating Black culture in America. Congress described it as a "vital American cultural ambassador to the world" in 2008.Desktop Version
