Hey, don t you guys have somewhere to be?
Known in North America as caribou, reindeer are built to live in freezing Arctic regions like northern Norway, where this herd was photographed under the transfixing swirl of the aurora borealis, or northern lights. Reindeer have evolved unique features that help them thrive in these harsh environments. Their noses are adapted to warm the air they breathe before it enters their lungs, which helps maintain a steady body temperature even in the coldest of weather. And most of their bodies, including their hooves, are covered with thick, dense fur to keep them well insulated. In fact, they are more likely to overheat then freeze—so when they"re flying through the starry skies tonight, they"ll be feeling snugger than Santa Claus in his red velvet suit.Desktop Version
Spring equinox
Spring equinox
Every year around March 20, the sun aligns with the Earth"s equator, and day and night are about equal in length. In the Northern Hemisphere, this is called the spring or vernal equinox, and it marks the astronomical exit of winter into the brighter, warmer springtime. From now on, we can enjoy days that are longer than nights. And a sharp eye might spot a flowering crocus, like the ones in today"s image, among the first flowers to bloom every year.Desktop Version

American bison
For an American bison, winter is the season to slow down, plump up, and let your hair grow out. Relatable, sure, but these massive mammals get there without the aid of beer, chips, and a couch.Desktop Version
Sky island views
Sky island views
Though it"s December, it isn"t cold and snowy everywhere in North America. Here, near Tucson, Arizona, the Sonoran Desert stays warm year-round. In this photo, we"re looking at a "sky island"—an isolated, high-elevation woodland surrounded by radically different lowland environments. In this case, the desert land at the base of the mountain is peppered with saguaros—a stately cactus recognized for its long arms. The snow-capped Santa Catalina Mountains in the distance are part of the Madrean Sky Islands and are home to Mount Lemmon Ski Valley, which is the southernmost ski destination in the US. The ski area covers the slopes of Mount Lemmon, which reaches an elevation of about 9,100 feet at the summit and can receive around 180 inches of snow annually.Desktop Version
Longer days mean warmer sand
Longer days mean warmer sand
Today we’re hitting the beach in Costa Rica’s Cahuita National Park because, well, just take a look at this place. If the sun gets too intense, we might take a stroll into the park’s lowland wet forest where, if we’re lucky, we’ll see sloths, toucans, and howler and capuchin monkeys; or maybe we’ll encounter armadillos, coatis, iguanas, and tamanduas (anteaters). After that, we’ll take a dip in the Caribbean waters offshore to marvel at coral reefs, sea turtles, and hundreds of species of fish.Desktop Version
Three cheers for polar bears!
Three cheers for polar bears!
February 27 is International Polar Bear Day, an observance created to bring attention to the important role these alpha predators play in the Arctic ecosystem. Though polar bears aren"t endangered—their current conservation status is "vulnerable"—these magnificent beasts have become a sort of mascot for the race to slow the melting of Arctic sea ice. The Arctic ice is crucial to the bears" survival, as they hunt the ringed seals that bob up through holes in the ice. As Arctic ice decreases, the polar bears" hunting ground does too.Desktop Version
Climb a tree for wild animals and plants
Climb a tree for wild animals and plants
Today is World Wildlife Day, the annual United Nations celebration of the incredible diversity of our planet"s wild animals and plants. The theme of this year"s WWD is "Forests and Livelihoods: Sustaining People and Planet." Through a series of virtual events, and a panel at UN headquarters, UN representatives and partner wildlife groups will examine the links between the state of our planet"s forests and woodlands and efforts to preserve the millions of livelihoods that directly depend on them. A particular emphasis will be placed on the role of Indigenous peoples who still live and work in forested areas, how they"ve successfully managed their forest ecosystems for centuries, and what that can teach us about sustainability.Desktop Version
Antarctica Day
Antarctica Day
At just over 600 miles from the tip of South America, Cuverville Island is closer to civilization than most of Antarctica. As such, this small isle off the northward-jutting Antarctic Peninsula is a hotspot for tourists to catch some cool scenery (while freezing their butts off, of course). Visitors can also chill on the rocky beach with the locals: a glut of gentoo penguins whose rookery here is the largest along the peninsula.Desktop Version
Lighting it up for Vivid Sydney
Lighting it up for Vivid Sydney
It’s winter in Australia, and the residents of Sydney fend off the winter gloom with a citywide festival. The wild light shows of Vivid Sydney encourage people to explore the city and see it in a new light. (Sorry. That had to happen.) Our photo shows the interior of "PJ the Port Jackson Shark," a light sculpture at the Taronga Zoo. It allows visitors to walk into the mouth of the ‘shark.’Desktop Version
The long and wiggling path
The long and wiggling path
In 1926, Walter Ruesch, the first superintendent of Zion National Park in Utah, oversaw the construction of this section of the Angels Landing Trail, one of the park"s most ambitious trails. Although he had no previous engineering experience, Ruesch planned the steep 21-switchback path out of Refrigerator Canyon up to Angels Landing. The section of the trail, now affectionately called Walter’s Wiggles, was first built to enable horses" access to Cabin Spring. One of the most difficult and dangerous sections of the Angels Landing Trail, Walter"s Wiggles was resurfaced in 1985 in a project that required 258 helicopter flights to haul in concrete for the job.Desktop Version
Salmon migration in full swing
Salmon migration in full swing
If you live in the Pacific Northwest, you may get a chance to view migrating salmon this fall. For the sockeye salmon shown here, the epic journey takes them from the waters of the Pacific Ocean back to the freshwater lakes and streams where they were born. There they’ll spawn, their bodies turning from a silvery blue to crimson and changing shape in the process. This isn’t always an easy journey. Dams and other human interventions have affected salmon runs, and West Coast salmon numbers have been in decline. We’re fans of groups like Long Live the Kings, a Pacific Northwest nonprofit that’s helping rebuild salmon populations and protect their habitat—for the long run.Desktop Version
Arctic fox in Norway
Arctic fox in Norway
We"re visiting Norway"s Dovrefjell–Sunndalsfjella National Park, where this small but mighty Arctic fox is undergoing changes to prepare for the cold, Nordic winter. While animals have many ways to adapt to winter weather, such as migrating, hibernating, and growing thick fur, the Arctic fox does none of these. Instead, its coat transitions from brown and gray to a snowy white every autumn. The fox"s pelt acts as camouflage, allowing it to blend in among the rocks and tundra for half of the year and, after turning white, hide in the snow and ice the other half.Desktop Version
Dog days of summer
Dog days of summer
The weather is warmer, and the days are longer, which can only mean one thing—the dog days of summer have arrived. These Cape foxes are helping us celebrate the dog days with their frolicking in the Kalahari Desert. They may not be the kind of "dogs" you typically think of, but Cape foxes are from the same family (Canidae) as the pooches you know and love. Partly to escape the heat in the desert scrubland it prefers, the Cape fox is most active just before dawn or after dusk, commonly spotted during the early mornings and early evenings.Desktop Version
Sailing on thick ice
Sailing on thick ice
New York"s Hudson River, winter of 2014: Temperatures were so cold for so long that sailors were able to take their antique wooden ice yachts out for a sail on this 20-mile stretch of thick ice. It was a rare sight for the area. Global warming meant that the Hudson River hadn"t frozen thick enough for safe iceboating in years.Desktop Version
Rising up from the black sand like rock gods
Rising up from the black sand like rock gods
Any visitor to Iceland knows that driving the Ring Road rewards the traveler with incredible changing landscapes. Today, we"re taking a quick detour to visit this chiseled stretch of Iceland"s southern coast, where black sand beaches meet spiky basalt sea stacks. This is Reynisfjara Beach, widely considered the most beautiful example of Iceland"s black sand beaches. The sea stacks fronting the beach are known as Reynisdrangar and were formed when a volcano erupted, spewing flowing lava that cooled into these formations. Ask the locals how they formed, however, and you may get a different story, one involving trolls and a battle with a three-masted ship.Desktop Version
Happy Astronomy Day!
Happy Astronomy Day!
No, that"s not a downpour of lightsabers—but it"s no typical night sky either. Stargazing here at Paranal Observatory, on a mountaintop in Chile"s desolate Atacama Desert, you"ll get one of the clearest possible naked-eye views of the southern skies. This "lightsaber" effect comes from the photo"s long exposure: What we"re seeing is these stars" paths as they track across the night sky due to our planet"s rotation. The dazzling colors indicate temperature, from chilly red (5,000-ish degrees Fahrenheit) to balmy blue (temps in the tens of thousands).Desktop Version
Of moles and liquid nitrogen
Of moles and liquid nitrogen
What a coincidence! Three days into National Chemistry Week, we dive further into STEM education to celebrate Mole Day. We’re not toasting the burrowing animal, but the unit of measurement (mole) used primarily in chemistry and molecular science studies. We don’t know how many moles of liquid nitrogen are in this photo, but we do like the dynamic look of the super-cooled element, which in liquid form can resemble boiling water. We hope this photo doesn’t depict liquid nitrogen after somebody in the lab dropped their keys into the vat. At minus 320 degrees Fahrenheit, liquid nitrogen tends to flash-freeze anything immersed in it.Desktop Version

It"s grape-harvesting time on Pico, a centuries-old tradition that kicks off in early September. Pico is one of nine islands comprising an autonomous region of Portugal called the Azores archipelago. The islands themselves are the peaks of vast volcanic mountains that rise high above the North Atlantic Ocean.Desktop Version

It s National Camera Day. Get the picture?
Here on the green grass of Cape Coral, Florida, this owl looks ready for his closeup, and ready for National Camera Day. June 29 commemorates photographs, the camera, and their invention. The history of the camera goes all the way back to the ancient Greeks and Chinese, who used pinhole cameras (camera obscuras), similar to what you might use to view a solar eclipse. The camera obscura could project an image but didn’t leave a lasting one.Desktop Version
A tower of light
A tower of light
Today is the International Day of Peace, an annual observance created by the United Nations and first celebrated in 1982. To recognize this noble effort, we bring you to Viðey Island, just north of Iceland’s capital of Reykjavik. The island is home to the Imagine Peace Tower, a ring of lights and mirrors that beams up nearly 2.5 miles into the night sky. It was created by Yoko Ono as an extension of the peace campaign started by the artist and her late husband, John Lennon. The base features the phrase ‘Imagine Peace’ in 24 different languages. When speaking of today’s observance, the UN defines ‘peace’ in the broadest terms–ceasefires and truces, however temporary, are all lauded as efforts to create a world free of violence.Desktop Version
Celebrating the UN’s International Day of Families
Celebrating the UN’s International Day of Families
In honor of the UN’s International Day of Families, we present the hyrax–a species with a rather surprising family tree. These furry mammals are often mistaken for rodents, but they’re more closely related to the elephant and manatee. Hyraxes even sport tusk-like incisors like their elephant cousins. To stay warm, they spend much of their time sunbathing, an activity which makes them vulnerable to predators. But even hyrax families look out for one another—and a male hyrax will stand guard to watch for potential threats.Desktop Version
Social climbing
Social climbing
March 2019 saw the opening of a structure called "Vessel" that overlooks the Hudson River in New York. "Vessel" is a 16-story, honeycomb-looking staircase that’s meant to be climbed. Its 154 flights of stairs are interconnected, much like Indian stepwells, which lent inspiration to designer Thomas Heatherwick. Not to worry. For those who would rather skip the 2,500 steps, they can reach the top via elevator.Desktop Version
Islands of the Salish Sea
Islands of the Salish Sea
The San Juan archipelago is made up of over 400 islands and rocks, some only visible during low tide. They"re scattered across the Salish Sea between Washington state and Vancouver Island, British Columbia. No bridges connect the San Juans to the mainland, but four of the largest islands—San Juan, Orcas, Lopez, and Shaw—are accessible via the Washington State Ferries system. Tourists come to the islands to take in the stunning coastal views, catch a glimpse of resident orcas, and partake in many outdoor activities, such as sea kayaking, biking, and hiking.Desktop Version

Ski touring in Austria
The High Tauern mountain range above the Austrian spa town of Bad Gastein is one of many regions around the world that attract brave ski-touring enthusiasts, like the three skiers crossing the ridge here. Ski touring is a sport for only the most skilled athletes since it usually involves navigating remote alpine territory and climbing with mountaineering gear, generally without removing your skis.Desktop Version
Aloe in bloom
Aloe in bloom
The bright flowers of these aloe plants offer a striking contrast to their more recognizable green, spiky stems. Native to Africa, Madagascar, and the Arabian Peninsula, aloes—including the well-known aloe vera species—are now grown outdoors in many locations that boast mild winter climates. They can bloom at any time throughout the year. And yes, even indoor potted aloes can be encouraged to bloom with the right amount of sunlight, water, and fertilizer.Desktop Version
