Tide pools in La Jolla, California, United States
Tide pools in La Jolla, California, United States
Not every science lesson requires a classroom. In La Jolla in California, United States, tide pools teach you about ocean life—right at your feet. Along the rocky shoreline of this San Diego coastal neighbourhood, tide pools form during low tide as seawater gets trapped in natural depressions. These shallow pools form naturally along La Jolla"s rocky shorelines, especially near Windansea Beach, Shell Beach, South Casa Beach and Hospital Point. The water that remains trapped in sandstone and reef depressions creates habitats for everything from sea hares to brittle stars.Desktop Version

Aerial view of Plaza Mayor, Madrid, Spain
Seen from above, the uniform arcades and tiled rooftops of Plaza Mayor in Madrid—the capital of Spain—create a captivating architectural harmony. Once the site of a bustling market square known as the Plaza del Arrabal, this historic space has witnessed the city"s transformation over the centuries. The shift began in 1561, when the plaza came under Madrid"s jurisdiction after the royal court moved from Toledo. Inspired by a vision of order and grandeur, King Philip II reimagined the square—though construction did not actually begin until 1617, under the reign of Philip III.Desktop Version
Nuuk, Greenland
Nuuk, Greenland
Picture a city where your daily commute offers views of fjords, drifting ice and the Northern Lights. That"s everyday life in Nuuk, the capital of Greenland—a small yet spirited Arctic hub blending Inuit heritage with Nordic modernity. Founded in 1728 by Danish-Norwegian missionary Hans Egede, it began as a small settlement called Godthaab—"Good Hope."Desktop Version
Coral Reef Awareness Week
Coral Reef Awareness Week
Every third week of July, Coral Reef Awareness Week reminds us that beneath the ocean"s surface lies a world as rich and complex as any rainforest. Coral reefs—like the staghorn coral pictured here—are home to roughly 25% of all marine species, despite covering less than 1% of the seafloor. These ecosystems not only support ocean biodiversity but also protect coastlines and drive economies through tourism and fishing.Desktop Version
Keel-billed toucan, Costa Rica
Keel-billed toucan, Costa Rica
Spot a flash of yellow on its chest and a bill that looks painted by an artist—that"s the keel-billed toucan. A member of the Ramphastidae family, which includes toucan barbets, it is one of more than 40 toucan species. Found from southern Mexico to northern Colombia, it spends much of its day plucking fruit with a rainbow-coloured bill about one-third of its total length. It also eats insects, eggs and small reptiles when available. The bill not only helps it eat but also keeps the toucan cool by radiating excess heat—thanks to the blood vessels running through it. This social bird often moves in small groups, chattering and gliding between treetops. With each wing measuring around 17-20 centimetres, the keel-billed toucan moults, or sheds its feathers, just once a year.Desktop Version
Scotts Bluff National Monument, Gering, Nebraska, United States
Scotts Bluff National Monument, Gering, Nebraska, United States
Long before GPS, natural landmarks like Scotts Bluff rose high above the prairie, signalling to travellers that they were on the right path heading west. Before Gering became a town in 1887—and decades before Nebraska achieved statehood in 1867—these sandstone and siltstone formations were already serving a purpose. They had long guided thousands along the Oregon, California, and Mormon Trails. Scotts Bluff National Monument is named after Hiram Scott, a fur trader with the Rocky Mountain Fur Company who died under mysterious circumstances nearby in the 1820s.Desktop Version
Spine-cheeked anemonefish
Spine-cheeked anemonefish
That bright fish hiding in the anemone? That"s the spine-cheeked anemonefish, or the maroon clownfish, and it is not just a cute creature. Native to the Indo-Pacific, from western Indonesia to Taiwan and the Great Barrier Reef, this species lives on the edges of coral reefs. This fish is easily distinguished by the spine extending from each cheek—hence the name. Groups of spine-cheeked anemonefish form around a single dominant female, and if she disappears, the top male steps up—literally changing sex to take her place. It thrives in warm, shallow waters and sticks close to its chosen sea anemone.Desktop Version
World Nature Conservation Day
World Nature Conservation Day
Every July 28, World Nature Conservation Day reminds us that protecting nature isn"t optional—it"s essential. Mongolia"s vast grasslands, featured today, are a powerful example. These ecosystems are among the largest intact temperate grasslands on Earth, stretching across millions of square kilometres of open steppe. They support around 200,000 nomadic herder families and provide habitat for rare species like the Mongolian gazelle and snow leopard.Desktop Version
A female Eurasian red squirrel, Switzerland
A female Eurasian red squirrel, Switzerland
Quick, clever and always on the move—meet the Eurasian red squirrel, a leafy treetop resident found across much of Europe and Asia. While it prefers the shelter of forests, this agile creature easily adapts to gardens and parks. It builds its nest, called a drey, high in the fork of a tree using twigs to form a domed structure about 25 to 30 centimetres wide. The female featured here is gathering moss—one of several soft materials, along with bark, leaves and grass, that line the nest and turn it into a snug, well-insulated retreat. These rodents may also take over tree hollows or abandoned woodpecker holes when available.Desktop Version
Asteroid Day
Asteroid Day
Each scar on Earth from a meteorite impact tells a story—from the asteroid that wiped out the dinosaurs to the lesser-known craters that dot the planet. Asteroid Day highlights ongoing research into asteroids and the potential threats they pose. Started in 2015 and backed by the United Nations, this day marks the anniversary of the Tunguska event—a massive explosion that occurred in Siberia on June 30, 1908. This explosion flattened over 2,070 square kilometres of Siberian forest near the Tunguska River. The blast released energy equal to 10–15 megatons of trinitrotoluene (TNT), a standard measure of explosive force. Since then, craters like Arizona"s Barringer, Quebec"s Manicouagan and others have helped scientists study what happens when space rocks hit Earth.Desktop Version
Northern gannets, Shetland Islands, Scotland
Northern gannets, Shetland Islands, Scotland
Graceful, powerful and impossible to miss—the northern gannet is the largest seabird on the waters of the North Atlantic. It spends most of its time gliding over open seas and returning to land only to breed. These seabirds, known for their vast and noisy breeding colonies, called gannetries, nest on steep cliffs, remote rocky islands and sea stacks that rise from the ocean.Desktop Version
Shark Awareness Day
Shark Awareness Day
Sharks have been around for over 400 million years—outlasting dinosaurs, surviving ice ages and weathering mass extinctions. They are symbols of ocean health, which is why Shark Awareness Day draws attention to these apex predators that help maintain balance in marine ecosystems. Protecting sharks means preserving the health of entire ocean environments—and ultimately, securing a sustainable future for all life. With many shark species facing the threat of extinction, this day is all about appreciating their ancient legacy and learning how we can help keep them off the endangered list.Desktop Version
Temple of Philae, Aswan, Egypt
Temple of Philae, Aswan, Egypt
The Temple of Philae, often called the Temple of Isis, is one of Egypt"s most enchanting ancient sites. Originally built on Philae Island, it was moved to nearby Agilkia Island to save it from flooding. The international rescue effort, launched by UNESCO in the 1960s, required a monumental effort that involved moving more than 40,000 stones. Today, it"s a peaceful spot surrounded by the Nile—perfect for a scenic boat ride and a journey into the past.Desktop Version
Maritime forest in Cumberland Island National Seashore, Georgia, United States
Maritime forest in Cumberland Island National Seashore, Georgia, United States
Before you hit the beach, you"ll hear it—the rustle of leaves in salty air, the creak of twisted trunks, the hush of an old world. Welcome to the maritime forest of Cumberland Island National Seashore on the southernmost stretch of Georgia"s Atlantic coast in the United States. Salt spray, sandy soil, hurricanes? The trees here stand their ground. Live oaks bend but don"t break. Saw palmettos crowd the ground like leafy bodyguards, while Spanish moss hangs from branches like nature"s fringe. This maritime forest is one of the best remaining examples of this rare habitat in the United States. Thanks to its national seashore status, the island has been spared from the concrete creep seen on other coastlines.Desktop Version
Boxing Day
Boxing Day
The best thing about Boxing Day is that it doesn"t ask much of you. No big countdown. No dramatic unwrapping. No last-minute dashes for batteries. It"s a rare holiday that says, "Sit down, finish your leftovers and take a moment." Celebrated on December 26 in Canada, United Kingdom and some Commonwealth countries, it"s a national cool-down after Christmas has done all the heavy lifting. The term goes back to Victorian Britain, when households prepared Christmas boxes for workers and tradespeople—tokens of thanks that ranged from coins to essentials. Churches joined in by opening alms boxes and distributing donations.Desktop Version
International Day of the Tropics
International Day of the Tropics
Every June 29, the International Day of the Tropics shines a light on the equator-hugging zone where the sun sticks around, and climate conversations get real. The tropics span a broad region between the Tropic of Cancer and the Tropic of Capricorn, including parts of Asia, Africa, Oceania, Central America and South America. Nearly 40% of the global population lives in this band, which also hosts 80% of the world"s biodiversity. It"s rich in culture, nature and history—but also under pressure from rising temperatures, deforestation and fast-paced urban growth.Desktop Version
International Day of Friendship
International Day of Friendship
What do giant handshakes painted on the ground have to do with friendship? Quite a lot, actually. Celebrated every July 30, the International Day of Friendship reminds us that tackling global challenges, like poverty, violence and injustice, starts with something surprisingly simple: human connection. That"s exactly what artist Saype had in mind with "Beyond Walls," a series of massive, biodegradable land-art murals featuring interlinked hands. Symbolising unity and solidarity, these works have stretched across five continents. At Expo 2020 Dubai, Saype"s 11th installation covered over 1,486 square metres of grass in Al Forsan Park. It formed a striking black-and-white handshake that could only be fully appreciated from above, as seen here. The piece, made with eco-friendly paint, was unveiled on Switzerland"s National Day, supported by the Swiss Pavilion.Desktop Version
Anshun Bridge, Chengdu, China
Anshun Bridge, Chengdu, China
The shiver felt under a full autumn moon, when the air hints at winter"s arrival, has a way of lingering in memory. One of China"s most cherished holidays, the Mid-Autumn Festival—also known as the Moon Festival—adds another touch of magic to the end of the harvest season. It"s celebrated on the 15th day of the eighth lunar month of the Chinese calendar—this year, on October 6. According to legend, it"s also the night when the moon goddess Chang"e watches over the world.Desktop Version
Plate ice along Lake Superior, Grand Marais, Minnesota, United States
Plate ice along Lake Superior, Grand Marais, Minnesota, United States
When winter tightens its grip on Lake Superior in Minnesota, the shoreline transforms into a landscape of tilted, glass-like shards known as plate ice. Thin sheets fracture under shifting temperatures, then drift and stack as the wind presses them toward land. The result is a field of translucent blues and silvers, catching the light at sharp angles and making the water"s edge appear sculpted rather than frozen.Desktop Version
The citadel in Bonifacio, Southern Corsica, France
The citadel in Bonifacio, Southern Corsica, France
Set at Corsica"s southern edge, Bonifacio looks out across a narrow strait to Sardinia, its limestone cliffs towering above the waves. Bonifacio didn"t begin as a picturesque tourist destination—it was originally established as a coastal fortification and has spent centuries guarding one of the Mediterranean"s busiest sea lanes. Established in 828 CE by Boniface II of Tuscany, the commune gradually became a meeting point for traders, soldiers and sailors—each group contributing to the evolution of the town"s structure. Bonifacio is divided into two sections, with the "vieille ville" (old town)—also known as "la Haute Ville" (the Upper City)—standing on a high cliff within the original citadel walls. Below, the marine area lines the narrow inlet with harbours, waterfront homes and a growing valley community.Desktop Version

St. Gregory Church in Ani Ruins, Kars, Türkiye
On a windswept plateau in eastern Türkiye, along the border with Armenia, the ruins of the ancient city of Ani rise from the landscape with striking clarity. A millennium ago, Ani was a thriving Armenian capital on a major Silk Road route, its fortifications and busy streets shaping trade and culture across the region. Today, the city is quiet, but its outline still carries the weight of its past.Desktop Version
World Sea Turtle Day
World Sea Turtle Day
They"ve got built-in helmets, a slow-and-steady vibe and zero interest in your deadlines. Sea turtles, like this one photographed in Fernando de Noronha, Brazil, have been cruising Earth"s oceans since before T-rex was a thing. Today, World Sea Turtle Day, is about recognising these ancient navigators and the role they play in keeping our oceans in balance. Why June 16? The date marks the birthday of American conservationist Archie Carr, known as the "father of sea turtle conservation." His work laid the foundation for understanding turtle behaviour and fighting for their protection.Desktop Version

There"s something timeless about Capitol Reef National Park—a place where red rock cliffs, winding canyons and ancient stories come together under Utah"s desert sky. Designated a national park in 1971, Capitol Reef invites reflection—not just on its vivid geology, but on the ancient narratives and cultural heritage etched into its landscape.Desktop Version
Christmas Bird Count
Christmas Bird Count
Each December, thousands swap wrapping paper for binoculars and step outside for a different kind of holiday tradition: the Christmas Bird Count. Started in 1900 by ornithologist Frank M. Chapman, the count offered a peaceful alternative to the Christmas "side hunts," where people competed to shoot the most animals. Chapman had a better idea: to count them instead. Over a century later, that simple shift has grown into the world"s longest-running citizen-science project.Desktop Version
Glen Brittle, Isle of Skye, Scotland
Glen Brittle, Isle of Skye, Scotland
Mists curl, waters glimmer and legends linger—welcome to Glen Brittle. On the Isle of Skye, Scotland"s fabled "Misty Isle," the glen stretches in a sweep of purple heather carpeting its rugged slopes. The landscape hums with echoes of the past: dinosaurs left footprints on these cliffs long before Mesolithic hunters traced its streams over 8,000 years ago. In the 9th century, seafaring Norse Vikings settled here. Centuries later, the powerful MacLeod and MacDonald clans claimed these lands, their castles standing guard over countless battles and alliances.Desktop Version
