The Sphinx Observatory isn’t the highest astronomical observatory on Earth, but it might feel like it to the lucky travelers who visit. To reach the observatory, they take a train up into the Alps, alight at Europe’s highest railway station, and ascend in an elevator tunneled inside the mountain. Once on top, stargazing is the academic focus, but visitors can take in sweeping views from the Sphinx’s 11,716-foot vantage. On either side are the Jungfrau and the Mönch, both members of the ‘four-thousander’ club—mountains that tower at least 4,000 meters (that’s 13,123 feet) above sea level.Desktop Version
The desert blooms
The desert blooms
It"s getting to be wildflower season in the Sonoran Desert in Arizona. That means it won"t be long before we see blooms from the big daddy of the cactus world—the saguaro. Our homepage pic shows just a glimpse of this amazing succulent. The saguaro is the largest of them all, with some of the oldest specimens reaching more than 50 feet tall. It can hold huge amounts of water—after plentiful rains when it"s fully hydrated, a saguaro can weigh between 3,200 and 4,800 pounds. In the right conditions, it will live more than 100 years, growing arms as it ages, creating that classic cactus profile that"s associated with the desert and Old West.Desktop Version
Celebrating sea otters
Celebrating sea otters
Say hello to this mom and newborn pup in Monterey Bay, California, during Sea Otter Awareness Week. Sea otters shower their pups with attention, cradling them and grooming them for hours. But it"s more than a gesture of affection—a mom will rub her pup to fluff the pup"s coat, which causes the fur to retain air bubbles. The air insulates the pup from chilly water and sometimes causes the youngster to float like a cork. Sea otters can survive on land, but they spend most of their time in the water, sleeping above the surface and anchoring themselves with kelp—or by holding onto each other. When they get hungry, they use rocks as tools to hunt food and pry open shells—something that makes them relatively unique, as they"re one of the few animal species that can use tools.Desktop Version
All eyes on sustainability
All eyes on sustainability
We don"t need an excuse to highlight and celebrate wildlife, but as it turns out, today is the UN"s World Wildlife Day. This year"s theme is "Sustaining all life on Earth," focusing on biodiversity. The UN and its partners are producing a series of programs and social media activities, including an event at UN Headquarters in New York, a film festival, and an international youth art competition.Desktop Version
Singing praises of the oceans
Singing praises of the oceans
In Japan, mid-July brings an excuse to head to the beach. That"s because this time of year marks Marine Day (aka Ocean Day), an observance recognizing the close bond the island nation shares with the seas and ocean that surround it. Because Marine Day roughly coincides with the end of the rainy season, it has, over the years, become a sort of unofficial kickoff to the hot summer season. One place sure to attract visitors is the picturesque Minokake-Iwa rock formation seen here, lying off the island of Honshu and its mountainous 31-mile-long Izu Peninsula.Desktop Version
Welcome to the pack
Welcome to the pack
This fuzzy pup is a young gray wolf, the largest member of the dog family (Canidae). Gray wolf pups are born between March and May, blind and deaf, but after about three weeks they"re ready to leave the den and begin exploring their surroundings for the first time. It doesn"t take long–around six months–before they"ve grown enough to join their pack on hunts.Desktop Version
A state-of-the-art lookout on the Rock of Gibraltar
A state-of-the-art lookout on the Rock of Gibraltar
Make your way up the trails of this monolithic rock promontory to the Skywalk, an 8,000-square-foot glass platform that soars more than 1,100 feet above sea level. On a clear day, you can see three countries and two continents from here. These epic views draw tourists, as does the Rock’s legendary history. A British Overseas Territory since 1713, Gibraltar has long been a strategically important military outpost located near the southern tip of Europe on the Iberian Peninsula. Far below the Skywalk, visitors can take in military relics that date back to the first years of British rule here.Desktop Version
Celebrating Norwegian Constitution Day
Celebrating Norwegian Constitution Day
If you have Norwegian roots, May 17 is a day to celebrate. It was on this day in 1814 that the Constitution of Norway was signed, declaring Norway an independent kingdom. This historic neighborhood in Trondheim, Norway, would be an ideal place to celebrate. Trondheim is the Norway’s third-largest city, founded by Viking King Olaf Tryggyason in 997. Today, its colorful wharfs and waterways charm visitors from around the world.Desktop Version
At the gates of the ksar
At the gates of the ksar
At the eastern edge of the Atlas Mountains in Morocco, Aït Benhaddou stands suspended in time. The mud-brick "ksar" (fortified city) was first built roughly 1,000 years ago, catering to travelers along the former caravan route between the Sahara desert and the city of Marrakesh. As a prime example of Moroccan earthen clay architecture, Aït Benhaddou has been a UNESCO World Heritage Site since 1987. It"s no longer teeming with the large numbers of people who once lived there. But there are small markets and a few families within the city who cater to the visitors who come to walk its historic streets. As a symbol of Morocco"s enduring history, Aït Benhaddou would be a fine place to reflect upon the events of January 11, 1944, when Moroccan nationalists issued a public proclamation calling for the independence of their country, an audacious action that sparked the movement that would end colonialism by 1956.Desktop Version
The circular castle of Cornwall
The circular castle of Cornwall
Many generations watched fog roll over this countryside long before the bellicose Norman visitors who built this fortress got the chance. The peninsula of Cornwall has been populated since the Mesolithic period 10,000 years ago, and is one of the traditional Celtic nations—areas of the British Isles and France where the Celts" culture survived Roman, Norman, and other outside influences despite repeated attempts at incursion.Desktop Version
A hint of spring
A hint of spring
Native to Western Europe, and especially popular in Great Britain, snowdrops are the bulb you"ll want to plant if the cold, drab landscape of winter gets you down. These small bulbs bloom very early—sometimes as soon as January—and are commonly associated with the promise of spring. But plant enough of them, or come across a naturally occurring patch, and it can look like a light dusting of winter snow has coated the ground. Need a little hope to get you through this last stretch of winter? Look no further than the lovely snowdrop.Desktop Version
A Carpathian Christmas celebration
A Carpathian Christmas celebration
Nestled at the foot of Mount Tampa in the Southern Carpathian Mountains of Romania, Brașov is a wonderful example of medieval Europe"s intersecting cultures. Founded by Teutonic Knights, settled by Saxons and Hungarians, and influenced by the Ottoman Empire, the Tartars, and the native Romanians, the city"s Gothic architecture and unique cuisine reflect its rich history. The city"s Christmas market is held throughout the month of December and is dominated by a 90-foot-tall, live Christmas tree. The market"s numerous stalls feature food, drink, and local crafts.Desktop Version
The persistence of Perito Moreno
The persistence of Perito Moreno
Yes, it"s true that glaciers are shrinking, but not all of them. Perito Moreno, a low-lying glacier in southern Argentina, accumulates ice at about the same rate that it melts into chilly Argentino Lake. This equilibrium makes it one of the few glaciers worldwide that aren"t losing mass to climate change.Desktop Version
We stand with Ukraine
We stand with Ukraine
Ukraine grows so many sunflowers they"ve become regarded as the country"s national flower—and recently, as a symbol of resistance. Just like sunflowers standing tall against a blue sky, the people of Ukraine are holding strong while an unlawful invasion threatens their democracy. As Ukrainians battle for their nation"s existence, millions of people have been forced to flee their homes to an uncertain future.Desktop Version
Longtailed widowbird at Rietvlei Nature Reserve, South Africa
Longtailed widowbird at Rietvlei Nature Reserve, South Africa
With a name like ‘widowbird,’ you’d expect this dusky male to have a low-key love life. But those 20-inch-long tail feathers are highly favored by females, even though they can make it difficult for the males to fly on windy days. The display has been the subject of much study regarding sexually selected traits and the tradeoffs between physical constraint and attracting a mate, since the tail feathers don’t seem to aid in flight and may even cause a hinderance. Ah, the things we do for love.Desktop Version
Celestial Spain
Celestial Spain
Today we"re in the Extremadura region of western Spain, in the beautiful Monfragüe National Park near the border with Portugal. This 18-mile long, 4-mile wide stretch of nature in the province of Cáceres is framed by the Tagus and Tietar Rivers (it"s the Tagus that"s in our image today). The mountainous Peña Falcon rock face defines its western side. Much of the park is covered by a thick Mediterranean forest full of wildlife, making this place a destination for outdoor lovers of all sorts. It"s especially notable for the many birds: Over 280 species are found here, including storks, kingfishers, cormorants, and eagles, as well as one of the world"s largest reserves of black vultures and their tawny vulture cousins. Other wildlife routinely spotted in Monfragüe include otters, deer, wild boar, and Iberian lynx.Desktop Version
A hit ballet, long after its debut
A hit ballet, long after its debut
These days, Tchaikovsky’s ballet ‘The Nutcracker’ is an iconic holiday entertainment staple, produced by companies around the world. In this photo, the Moscow Ballet performs the seasonal crowd-pleaser in Toruń, Poland. But when the ballet debuted this day in 1892 in St. Petersburg, Russia, it was not a hit. ‘The Nutcracker’ was revived and restaged in the early 20th century, but still didn’t make an impact. Then in 1944, the San Francisco Ballet performed the American debut of the ballet to great acclaim. It became a true Christmastime classic 10 years later, when choreographer George Balanchine staged his own 1954 production with the New York City Ballet. Balanchine’s version caught on and inspired other dance companies to stage it themselves. Today, ‘The Nutcracker’ is often such a draw that a staging of Tchaikovsky’s Christmas fantasy can help keep a ballet company financially stable.Desktop Version
A fortress in the sky
A fortress in the sky
Beginning as a lone watchtower high in the Apennines of Italy in the 10th century, the fortress called Rocca Calascio gained more heft over the next few hundred years. A quartet of additional towers and heavy walls were gradually added around the first tower. These fortifications made clear that Rocca Calascio was ready for any military rivals who might scale the slopes from the valley below to attack this garrison. The fight never came. The ruins you see here are not battle scars but the result of a powerful earthquake. By the early 1700s, Rocca Calascio was abandoned, but it can still claim the title of highest fortress in the Apennines—and some of the most spectacular views in all of Italy. In fact, filmmakers have chosen the site for several movies, including "The Name of the Rose" and "Ladyhawke."Desktop Version

Every day is Napping Day for this screech owl
We can think of no better way to celebrate National Napping Day than with this furry fellow, a screech owl asleep in a tree trunk in the Massapequa Preserve on Long Island, New York. Found in wilderness areas and near human settlements from the Atlantic Seaboard to West Texas and up into Montana, Eastern screech owls like this one are well established in the US. They"re nocturnal creatures, so they sleep during the day and become active after dusk. But don"t worry about you or your pet getting attacked by these owls. While it"s not apparent from this picture, screech owls are tiny–smaller than a pint glass–and prefer to feast on insects, worms, and small rodents.Desktop Version
The parenting of a piping plover
The parenting of a piping plover
To celebrate Mother’s Day this year, we’re on Jones Beach Island in New York, where piping plovers are helping their newly hatched chicks prepare to leave the nest—just hours after they hatch. While mom and dad were sitting on the unhatched eggs, if a predator, such as a fox, raccoon, or house cat were to get too close, they’d fake an injured wing and limp away from the nest to distract the animal. That’s some extra-mile parenting! Who knows if that little chick will remember to call mom this time next year…Desktop Version
Quebec City for Winter Carnival
Quebec City for Winter Carnival
Among all the pre-Lenten celebrations that take place around the world in February, the most famous are associated with warm-weather cities like Rio and New Orleans, where revelers party in elaborate costumes during the run-up to Ash Wednesday. It"s a different affair in Quebec City, Canada, pictured here, where participants in the Quebec Winter Carnival enjoy all things winter, from snow sculptures to sleigh races. This former frontier outpost, and little sister to Montreal, is known for its spirited embrace of the coldest, darkest season. So, it"s no surprise that its winter festival is the biggest in the Western Hemisphere. Our homepage image shows the grandiose Château Frontenac hotel, which opened in 1893, towering over the city"s historic Old Quebec neighborhood, a UNESCO World Heritage Site.Desktop Version
High tide at the walled city
High tide at the walled city
Saint-Malo was founded by the Gauls more than 2,000 years ago and has an appropriately rich and storied history. Built on the Brittany coast of the English Channel, Saint-Malo became an important stop for ships coming into and out of Western Europe. And because of its strategic location, Saint-Malo was, for a time, a favorite spot for pirates, corsairs, and privateers—as ships made their way through the channel, pirates lurking off the Saint-Malo coast could pounce easily while French authorities looked the other way.Desktop Version
Hanging out on a limb
Hanging out on a limb
For International Red Panda Day, we"re hanging out on a tree limb with this cutie in the Chengdu Panda Base of Sichuan, China. If you spot a red panda in the wild, consider yourself lucky. Not only will you have to travel far (they live in the mountain forests of Nepal, Bhutan, China, Myanmar, and India), but there are fewer than 10,000 wild red pandas, and they"re rather elusive, hanging out up in trees. They also spend more than half their day asleep, conserving energy for—you guessed it—eating bamboo leaves. They spend a whopping 13 hours a day eating.Desktop Version
