Medieval towers in Mestia, Upper Svaneti, Georgia
Medieval towers in Mestia, Upper Svaneti, Georgia
Winter turns Mestia"s medieval towers into icy fortresses. Perched 4,921 feet up in the Caucasus Mountains, Mestia is a charming highland town in northwest Georgia. The town is home to the Svans, a cultural and linguistic subgroup of Georgians. Despite its modest size, Mestia has been an essential hub of Georgian culture for centuries, dotted with the Svan defensive towers, seen in today"s image. Most of these towers were constructed between the 9th and 12th centuries, a period often referred to as Georgia"s Golden Age. However, their roots are believed to stretch even further back, possibly into prehistoric times. Built for both protection and shelter, these towers were not just fortresses but also integral parts of family homes, reflecting the region"s history of resilience and self-sufficiency. Therefore, it isn"t just a town; it"s a living museum where history rises from these towers and echoes through the mountains.Desktop Version

Wallabies at sunrise, Australia
Wallabies at sunrise, Australia
Amid the hues of dawn, captured in today"s image, two wallabies stand alert in a field near the Adelaide River in Australia"s Northern Territory. These marsupials, smaller cousins of the kangaroo, are native to Australia and New Guinea. There are around 30 species of wallabies, including swamp, rock, and hare-wallabies. These sprightly mammals have strong hind legs that help them take impressive leaps and deliver powerful kicks if threatened. During mating season, male wallabies engage in boxing bouts in an attempt to grab females" attention. Social creatures, wallabies form small groups called "mobs" for safety and mutual grooming. Their playgrounds are forests that echo with the thudding of their hops as they navigate their home range.Desktop Version

Lei Day
Lei Day
As the first day of May dawns in Hawaii, Lei Day bursts forth in a riot of color, fragrance, and festivity. Leis are garlands crafted from flowers, leaves, and even shells, carrying significant cultural importance in Hawaiian culture. Leis were brought by the Polynesians as they migrated eastward through the Pacific Islands before reaching Hawaii between 1000 and 1200 CE. They represent love, respect, and the ever-present aloha spirit, described as "the coordination of mind and heart within each person." Lei Day is an all-day fiesta that includes parades, pageants, lei-making contests, hula dances, and feasts. It also marks the beginning of Asian American and Pacific Islander Heritage Month.Desktop Version
Katahdin Woods and Waters National Monument anniversary
Katahdin Woods and Waters National Monument anniversary
Welcome to Katahdin, where dense woodlands and pristine waterways stretch out as far as the eye can see. Covering nearly 87,500 acres, this new national monument was established eight years ago today. Maine"s logging industry was a big part of this region for over a hundred years but declined toward the end of the 19th century. Efforts to preserve its landscape were spearheaded by philanthropist Roxanne Quimby. She started buying land near Baxter State Park in 2001 and donated it to the federal government in 2016, ensuring its preservation for future generations.Desktop Version
World Octopus Day
World Octopus Day
What exactly are we looking at here? The veined octopus, also known as the coconut octopus, is one of the smartest animals on Earth, building shelters from seashells and coconut shells. If you peek inside, you may spot those telltale suction cups that cover the creature"s eight limbs. These arms contain clusters of neurons, which make them particularly sensitive, and each arm can be used separately to perform complex tasks. Octopuses can also match the color—sometimes even the texture—of their environment, making them even more difficult to spot. There"s lots more to learn about these fascinating animals, and World Octopus Day is a great day to do it. You could always start with the Academy Award-winning documentary "My Octopus Teacher."Desktop Version

Glacial rivers in Iceland
Glacial rivers in Iceland
Iceland"s glacial rivers have shaped the landscape here in the land of fire and ice over thousands of years. The rivers seen in today"s image are formed from the meltwater of vast glaciers like Vatnajökull, Langjökull, and Hofsjökull. Vatnajökull, the largest ice cap in Iceland, covers over 3,000 square miles—approximately 10% of the country"s landmass. As the glaciers melt, the water carries fine sediments, creating a braided river system with a milky appearance that contrasts with the earthy tones of the volcanic terrain. Every spring and summer, the rivers swell with seasonal meltwater, continually shaping and reshaping the land. Aerial views reveal their intricate patterns, interwoven across the terrain toward the North Atlantic Ocean. The water also powers hydroelectric power stations, reinforcing Iceland"s status as a leader in sustainable energy.Desktop Version
Daylight saving time begins
Daylight saving time begins
It"s the time of year again when clocks spring forward, stealing an hour of sleep but giving us longer evenings to enjoy. Daylight saving time (DST) starts today at 2 AM, except in Arizona and Hawaii, reminding us that time, quite literally, waits for no one. The idea is simple: maximizing daylight and reducing energy consumption by syncing our activities with the natural light cycle. This concept was popularized by Benjamin Franklin in the 18th century, though his suggestion to "save candles" was more satirical than a serious proposal. Fast-forward to the early 20th century, when many countries adopted DST to conserve fuel during wartime. The US officially standardized it in 1966 with the Uniform Time Act. Today, DST runs from March to November in around 70 countries, giving eight months of extended evening light.Desktop Version

International Day for Biological Diversity
International Day for Biological Diversity
Life on Earth, from tiny bacteria to towering trees, is interconnected. International Day for Biological Diversity is about celebrating this web of life that keeps our planet thriving. Biodiversity ties into everything, from sustainable farming and clean water to climate action and disaster preparedness. A decline in biodiversity can increase the spread of zoonotic diseases—those transmitted from animals to humans. In contrast, protecting biodiversity strengthens our ability to prevent and respond to health crises like pandemics. Recognizing its crucial role for current and future generations, the United Nations observes this day each year to raise awareness and foster action for conserving the planet"s biological treasures.Desktop Version
Arches National Park anniversary
Arches National Park anniversary
Red as far as the eye can see and clear blue skies overhead. Welcome to Arches National Park, Utah. The story of this otherworldly landscape starts 65 million years ago when a dry seabed stood here. Over time, geological forces warped and squeezed the land, twisting the sandstone into lumps and bumps. Later, wind and water carved out the arches, pinnacles, fins, and balanced rocks that now stand in this area. The park has more than 2,000 natural stone arches, the highest concentration of these structures anywhere on Earth. In today"s image, we can see two of them: Double Arch, as seen through Cove Arch. The larger arch of Double Arch spans 144 feet and is 112 feet tall, the tallest and second-longest of the park"s arches.Desktop Version

International Surfing Day
International Surfing Day
Today, everybody"s hitting the waves for International Surfing Day! This event is about celebrating surfing while also drawing attention to the importance of protecting ocean environments to keep their waters pristine for wildlife and surfers alike. Surfing has a long history; around 5,000 years ago in Peru, people used reed watercraft to surf the waves when they were out fishing. It was in pre-colonial Hawaii, however, that modern surfing was born. Here, people started to stand on their boards and to surf for fun. Historians believe that surfing made its way to the US in 1885, when three teenage Hawaiian princes surfed on redwood boards while on a break from boarding school in California.Desktop Version
