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
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
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
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
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
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
Wheatear, Peak District National Park, England
Wheatear, Peak District National Park, England
You don"t need to be a bird expert to notice the wheatear darting across open ground. These ground-dwelling songbirds belong to the Oenanthe genus and are known for their upright posture and habit of hopping or sprinting between perches. Despite the name, wheatears have nothing to do with wheat or ears—the name is a twist on the old phrase "white arse," pointing to the bird"s distinctive white rump found in most species.Desktop Version
World Lake Day
World Lake Day
Nature has its tricks, and Sørvágsvatn is one of its best. World Lake Day is the perfect occasion to explore this optical illusion in the Faroe Islands, an autonomous administrative division of the Kingdom of Denmark. Also called Leitisvatn, this lake on the island of Vágar appears to float far above the ocean. In reality, it sits less than 30 metres above sea level. As the largest lake in the Faroes, Sørvágsvatn has a surface area of about 3.4 square kilometres and feeds the Bøsdalafossur waterfall, where its waters pour dramatically into the sea.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
International Day for the Conservation of the Mangrove Ecosystem
International Day for the Conservation of the Mangrove Ecosystem
As twilight descends on Walakiri Beach on the island of Sumba, Indonesia, the silhouettes of mangrove trees stand like sentinels in the tide—graceful, resilient and vital. Today, on International Day for the Conservation of the Mangrove Ecosystem, we honour these extraordinary trees and the critical role they play in sustaining life on our planet.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
Moon Day
Moon Day
Every July 20, we celebrate National Moon Day, marking the historic moment when Neil Armstrong first stepped onto the moon in 1969. With his iconic words, "That"s one small step for man, one giant leap for mankind," Armstrong became the first human to walk on the moon, followed by Buzz Aldrin.Desktop Version
A pine forest in Alsace, France
A pine forest in Alsace, France
In December, the forests of Alsace, in France"s Grand Est region, wrap themselves in a veil of fog, as if nature were holding its breath before winter. Amid Scots pines and silver firs, the moss-covered ground muffles every step and the silence feels almost sacred. These woodlands, which cover nearly 40% of Alsace, shelter a rich biodiversity: roe deer, wild boar, black woodpeckers and sometimes the elusive lynx, which has returned after decades of absence.Desktop Version

Rock layers formed over millions of years and a massive bend in the Earth"s crust give this desert a rare window into geologic history. This is Capitol Reef National Park in Utah, where sandstone cliffs and canyons preserve a striking record of the planet"s past. Today"s featured image highlights the sandstone monoliths of Cathedral Valley, including the Temple of the Sun, part of this extraordinary, protected landscape.Desktop Version
Avalanche Lake Trail at Adirondack High Peaks, New York, United States
Avalanche Lake Trail at Adirondack High Peaks, New York, United States
There"s no easing into the wild here—the Avalanche Lake Trail carves a bold path through rock scrambles, narrow ledges and alpine serenity. Tucked away in the Adirondack High Peaks in New York, United States, this 0.04-square-kilometres alpine lake sits at nearly 880 metres between Mount Colden and Avalanche Mountain. Shaped by ancient glaciers, the lake is framed by dramatic cliffs and rugged terrain that echo its icy origins. Its most striking feature is the Trap Dike—a towering 370 metre rock canyon flanked by steep walls, making the lake one of the most awe-inspiring sights in the Adirondacks. Massive avalanches carved these cliffs, leaving behind the dramatic landscape that gave Avalanche Lake its name.Desktop Version

Forgetmenot Pond, Kananaskis Country, Alberta
Set in the foothills and front ranges of the Canadian Rockies, Kananaskis Country stretches across a vast network of protected valleys, dense forests and alpine peaks. Located in Alberta, the region was formally established in 1978, uniting several provincial parks and protected areas under a shared vision of conservation. Clear rivers cut through limestone cliffs, while spruce and pine forests rise toward high mountain passes.Desktop Version
Ring-tailed lemur
Ring-tailed lemur
It looks like this small creature is playing a game, right? But when a baby ring-tailed lemur wraps its tail around or gives it a tug, it"s actually working on crucial skills. The infants spend their early weeks hanging tight to their mom, first clinging to her belly and later to her back. As they grow, they separate from their mom, and tail-chasing becomes part of how they learn balance, coordination and group play. These primates use their long tails for communication as well. Raised like flags during group movement, the tails help them stick together in open terrain. Loud, rhythmic calls, scent markings and "stink fights" between males add to the social drama.Desktop Version
Anniversary of the Stonewall Uprising
Anniversary of the Stonewall Uprising
In the early hours of June 28, 1969, a police raid at the Stonewall Inn in New York"s Greenwich Village, met unexpected resistance. Fed up with years of harassment, LGBTQIA+ patrons fought back. What followed was six days of unrest—and the start of a movement. Led in part by American trans activists like Marsha P. Johnson and Sylvia Rivera, the uprising challenged not only police brutality but society"s silence. Stonewall wasn"t the beginning of queer existence, but it was the moment people said "no more" loud enough to be heard worldwide.Desktop Version
Reindeer, Lapland, Finland
Reindeer, Lapland, Finland
Few creatures evoke the magic of the holidays quite like the reindeer. Also known as caribou, they are the spirit animals of Christmas lovers—and they rock it. Sturdy and sure-footed, they"ve been pulling Santa"s sleigh ever since Clement Clarke Moore cast them in the role in his 1823 poem "A Visit from Saint Nicholas." And they were born for it. Their hooves shrink in winter to expose a gripping rim, then expand in warmer months for better traction.Desktop Version
Great white egret, Hungary
Great white egret, Hungary
Meet the great egret, also known as the great white egret. Found in the Americas, Asia, Africa and parts of Europe, these birds are often seen wading through wetlands, tidal flats and quiet streams. Patient and precise, they stand motionless for minutes, waiting for just the right moment to deliver a lightning-fast strike. Fish are their main prey, but they also eat frogs, reptiles and even small mammals. In Canada, great egrets are seasonal visitors, commonly spotted in southern Ontario and southern Quebec during the warmer months.Desktop Version
Trullo buildings in Alberobello, Apulia, Italy
Trullo buildings in Alberobello, Apulia, Italy
If fairy tales had architects, they might"ve come up with something like Alberobello in Italy. But instead of magic wands, it was limestone, mortar-free masonry and—according to some theories—a bit of tax evasion that built this town"s signature homes: the trulli. These are whitewashed stone houses topped with dry-stacked limestone roofs shaped like upside-down ice cream cones. It"s an ancient building technique, and in this case, a clever one. Back in the 14th century, locals were reportedly trying to avoid property taxes by constructing homes that could be quickly dismantled when the king"s tax collector came around.Desktop Version
Perseid meteor shower over Nevada
Perseid meteor shower over Nevada
Get ready for one of the most dazzling celestial displays of the year—the Perseid meteor shower. Active from mid-July through late August, it reaches its spectacular peak on the night of August 12 into the early hours of August 13 this year. The Perseids light up the skies when Earth passes through a trail of icy and rocky debris left behind by Comet Swift–Tuttle, which last passed close to our planet in 1992. These meteors are called the Perseids because they appear to streak from the direction of the constellation Perseus.Desktop Version
Badlands National Park, South Dakota, United States
Badlands National Park, South Dakota, United States
As the sun sets over Badlands National Park, the landscape transforms into a stunning display of colour. The national park, located in southwestern South Dakota, United States, features a dramatic terrain of eroded buttes, pinnacles and spires carved by millennia of wind and water. Spanning over 980 square kilometres, the park is divided into three main units: the North Unit, home to the visitor centre and scenic Badlands Loop Road; and the Stronghold and Palmer Creek units. The park"s dramatic terrain is the result of sedimentary rock layers eroding at a rate of 2 centimetres per year, revealing colourful bands of volcanic ash, silt and clay. These formations are not only visually striking but also rich in fossils, including remains from the Oligocene Epoch (about 33.9 to 23 million years ago), such as ancient horses, camels and sabre-toothed cats.Desktop Version
Belogradchik Rocks, Bulgaria
Belogradchik Rocks, Bulgaria
In Bulgaria, on the western slopes of the Balkan Mountains, the Belogradchik Rocks stand like a natural gallery where every formation tells a tale. Shaped over millions of years by erosion, these sandstone and limestone pillars twist and tower into outlines that locals swear resemble people, animals and even entire scenes. That"s why names like "The Horseman," "The Schoolgirl" and "The Monks" have stuck—it"s a landscape where spotting shapes feels a bit like playing nature"s version of charades.Desktop Version
