Anybody out there?
This is the time of year that polar bears emerge from their winter dens. In today"s photo, these adorable cubs are peeking out for the first time in their young lives. Polar bears don"t technically hibernate, but in fall, a pregnant female polar bear will dig a maternity den in the snow (although in some areas it"ll be under the peat soil). While in her small den, the bear enters a dormant state, sleeping nearly all the time, until she gives birth, usually between November and February. Then in spring she"ll dig herself out and emerge with her recently arrived cubs. Polar bear cubs stay with their mother for about two years as they learn to survive in the Arctic.Desktop Version
Cecil Brewer Staircase, London
Cecil Brewer Staircase, London
This stunning staircase spirals up through three floors at Heal"s department store in central London, where it has been helping shoppers get around in stylish fashion since 1916. It was designed by architect Cecil Brewer ahead of the opening of an in-store art gallery. While the gallery no longer exists, the Cecil Brewer Staircase remains a popular part of the store"s heritage, particularly with photographers looking to capture a little London glamour. The lights at the outer edge of the stairs were added after World War II, and the elegant chandelier cascading from top to bottom was installed in 2013. If you visit, keep an eye out for a bronze cat on a windowsill overlooking the stairs, the store"s not-for-sale official mascot.Desktop Version
Space is for everyone
Space is for everyone
The end of World Space Week today comes with a message of hope. Fifty-one years ago, the pact known as the Outer Space Treaty went into effect. The US, UK, and USSR were the first parties to the treaty and at least 107 other nations have since joined them, with additional countries working on ratification. The treaty establishes ‘space law’—in essence, an agreement that space exploration should only be for the benefit of all of humanity. No weapons of mass destruction can be placed on the moon, or any other orbiting body.Desktop Version
Alam-Pedja Nature Reserve, Estonia
Alam-Pedja Nature Reserve, Estonia
Among Estonia"s stunning natural sites is the Alam-Pedja Nature Reserve, covering 132 square miles of wilderness in the heart of the country. This occasionally ice-covered, vast area of wetlands, forests, and rivers is the largest natural reserve in Estonia. From the majestic white-tailed eagle to the elusive black stork, more than 200 bird species can be found here. The landscape is a tapestry of aquatic forests: still water, bog, and floodplain forests. Winding trails and boardwalks invite explorers to craft their own adventures.Desktop Version
A peak in the clouds

World Meteorological Day brings us to Washington"s Mount Rainier, a huge stratovolcano with a habit of creating its own weather systems. Jutting out about 2 miles above the surrounding landscape, its high altitude interrupts the flow of air that comes in off the Pacific Ocean, creating dramatic weather such as the saucer-shaped clouds on our homepage. They"re called lenticular clouds, and because of their distinctive appearance, they"ve been suggested as an explanation for some UFO sightings. Thanks to the science of meteorology, we know they"re a normal weather phenomenon, commonly occurring on the downwind side of obstructions such as mountains, buildings, or other tall structures.Desktop Version
To Roswell, and beyond!
To Roswell, and beyond!
Tourism in New Mexico is fueled in part by attractions such as the International UFO Museum and Research Center in Roswell—seen here in our photo today. Recognizing the revenue potential in embracing popular interest in UFOs, in 2003 the New Mexico State Legislature declared the second Tuesday in February each year to be Extraterrestrial Culture Day. Why New Mexico? The answer lies in the city of Roswell in the southeastern corner of of the state.Desktop Version
Celebrating 30 years of eye-opening images
Celebrating 30 years of eye-opening images
On this day in 1990, the Hubble Space Telescope entered orbit in the cargo bay of the space shuttle Discovery. Shortly thereafter, it began its continuing mission to capture images of our universe from low Earth orbit, free of the obstructions of clouds and the distortions of the atmosphere. Like its namesake, the great astronomer Edwin Hubble, the Hubble Space Telescope has transformed our understanding of the cosmos. Some of the telescope"s greatest contributions include its Deep Fields images, which peer back billions of light-years and help astronomers measure the size and age of the universe and test theories about its origin. It"s also produced jaw-dropping images of objects closer to home, like the one on today"s homepage. Here we"re looking at a maelstrom of glowing gas and dark dust within one of the Milky Way"s satellite galaxies, the Large Magellanic Cloud.Desktop Version

This spectacular landscape might just be the perfect place to celebrate Waitangi Day, New Zealand"s national holiday. It commemorates the 1840 treaty between Britain and some 500 Māori chiefs that established British law in the island nation. The Treaty of Waitangi is considered New Zealand"s founding document and a cornerstone in the country"s history. Another important legacy of the treaty is that it provided the framework for political relations between New Zealand"s government and the Indigenous Māori people.Desktop Version
A horse of many colors
A horse of many colors
Whitehorse, Yukon"s only city and the largest in northern Canada, will have just seven hours of daylight today, but nature has a way of compensating for this injustice. The area enjoys frequent and spectacular light shows, thanks to the aurora borealis. The mechanics of northern lights are still not fully understood, but scientists agree that solar winds—big pulses of energy from our sun—pass through the Earth"s magnetic fields, especially at the polar regions, resulting in shimmering colors.Desktop Version
Falling for the Canadian Rockies
Falling for the Canadian Rockies
Sunwapta Falls is one of several spectacular waterfalls in Jasper National Park in Alberta, Canada. It"s actually a pair of waterfalls, a lower and an upper one, on the Sunwapta River. Their water comes from the Athabasca Glacier, so volumes are higher in the summer due to seasonal glacial melting. Jasper National Park is the largest national park in the Canadian Rockies, with more than 4,000 square miles for camping, hiking, water sports, and other activities. Wildlife in the park includes elk, grizzly bears, moose, bighorn sheep, and caribou.Desktop Version

Prague, Czech Republic
As a haze of blowing snow diffuses the streetlights of Prague, try to count the steeples, belfries, turrets, and towers that make up the Czech capital"s skyline. You may lose count like 19th-century travel writers did when they dubbed Prague the City of 100 Spires. The number is closer to 500 currently.Desktop Version
Happy Thanksgiving from an expert face-stuffer
Happy Thanksgiving from an expert face-stuffer
The Siberian chipmunk is the only species of chipmunk found outside of North America. Its native habitat ranges from across Russia to northern China, Japan, and Korea. Though Siberian pine nuts are a favorite meal, these little rodents will eat nearly anything—seeds, fruits, insects, even small birds and lizards. Our ravenous friend here in Hokkaido, Japan, is gorging on inflorescences, or clusters of flowers. A chipmunk can stuff a surprising amount of goodies into its cheek pouches, which can stretch to three times its head size—imagine how ridiculous we"d look if our stomachs were as forgiving.Desktop Version
Defying gravity on a swing ride
Defying gravity on a swing ride
Can you smell the fried food and cotton candy? Fair season is upon us, and amusement rides are usually just part of the whole fair-going experience. The modern fair has roots in ancient times, tracing back to a variety of influences, from Roman religious festivals to temporary markets set up at crossroads along the trade routes from Asia to Europe. Today, county and state fairs often combine industry and agriculture exhibits with various entertainment options such as this swing ride. What’s your fair-season favorite?Desktop Version
Glowworm caves in Australia
Glowworm caves in Australia
Down under the land in the Land Down Under, cave explorers may find these subterranean spaces illuminated by an unlikely light source. Fungus gnat larvae—more affectionately known as glowworms—speckle the walls and ceilings of caverns here in Australia during the warm season, from December to March.Desktop Version

Brotherly cubs
They"re adorable to be sure, but we"re betting these two Kermode bear siblings are a handful (hang in there, mama bear!). We"re featuring them in honor of Siblings Day, an annual celebration of the bond between children who share one or more parent in common. Kermode bears are a subspecies of the American black bear, although they"re obviously not always black. They have a recessive gene that sometimes results in fur that"s cream- or white-colored. While most Kermode bears are black, scientists estimate that between 10% and 20% of the population have ivory coats. Known as "spirit bears," they are special to the indigenous peoples of the British Columbia coastal regions where they live.Desktop Version
A bridge that rocks
A bridge that rocks
Sandwiched between soaring pinnacles of sandstone, Bastei Bridge is a highlight of Saxon Switzerland National Park. But don"t be fooled by the park"s name because we"re not in Switzerland; we"re hundreds of miles away in eastern Germany, close to the border with the Czech Republic. The name comes from two Swiss artists who visited the area in the second half of the 18th century and felt the picturesque upland scenery was reminiscent of their homeland.Desktop Version
Spring comes to Glacier National Park
Spring comes to Glacier National Park
You can almost hear the rushing water in this picture of St. Mary Falls at Montana’s Glacier National Park. To get to this picturesque waterfall and its aqua-blue pools you’ll need to journey to the east side of the park near St. Mary Lake. Glacier is home to 700 miles of hiking trails, including the short day hike that leads to St. Mary Falls, taking visitors through conifer forests. If you feel like chasing more waterfalls, you can extend the hike and journey to nearby Virginia Falls. Don’t forget your camera and be on the lookout for woodpeckers, moose, and wildflowers.Desktop Version
Even nature needs a backup plan…
Even nature needs a backup plan…
This glittering concrete monolith is a lot like that still-sealed emergency survival kit languishing in your basement since 1999: Reassuring to have around, but a bummer when you actually have to use it. The Svalbard Global Seed Vault—better known by its cute nickname, the "Doomsday Vault"—was established on this far-northern Norwegian isle in 2008 to archive frozen genetic copies of seeds already housed in seed banks around the world: a backup of all the backups. Kept at minus 0.4 degrees F within the seed vault, precious botanicals from food to fibers to flowers are safe from disasters, even of the apocalyptic variety. Lucky us: It"ll take a healthy diet of veggies to fight off the zombies.Desktop Version
Speed skaters in the Gangneung Oval, Pyeongchang, South Korea
Speed skaters in the Gangneung Oval, Pyeongchang, South Korea
The Gangneung Oval in Pyeongchang, South Korea, is where all the speed-skating action of the 2018 Winter Games will happen. Long-track skaters wear spandex suits to help reduce friction and maybe skate just a bit faster as a result. But the short-track skaters at the games wear Kevlar suits to protect against cuts from other skaters’ blades. Those tight turns can result in collisions, so the cut-proof suits are true lifesavers.Desktop Version
Te Rewa Rewa Bridge near New Plymouth, New Zealand
Te Rewa Rewa Bridge near New Plymouth, New Zealand
This pedestrian and cycle bridge lets residents and visitors in the North Island city of New Plymouth cross the Waiwhakaiho River while marveling at the span’s artistic design. Said to resemble both a breaking wave and a whale skeleton, the bridge is meant to invoke the sacred relationship of the indigenous Māori people with the land, sea, and wind. On one side is an old Māori burial ground, so great care was taken in the design and structure of the bridge—an attempt to interfere as little as possible with the Māori site. From the view in this photo, Mount Taranaki lurks in the background.Desktop Version
Infrared Jupiter, erupting Io
Infrared Jupiter, erupting Io
To celebrate World Space Week, we"re featuring this montage of images of Jupiter courtesy of the New Horizons probe"s flyby of the planet in 2007. If Jupiter looks a little different than you"re used to seeing, it"s because it was imaged using the space probe"s near-infrared imaging spectrometer. In this false-color image, Jupiter"s high-altitude clouds, like its stormy Great Red Spot, are rendered white, while deeper cloud formations take on reddish hues. The planet"s innermost moon, Io, is captured in a true-color composite image during one of its frequent volcanic eruptions. A close look will show lava is glowing red beneath the blue and white plume of particles being ejected into the moon"s thin atmosphere.Desktop Version
Making it work—in Norway
Making it work—in Norway
Springtime is high-fashion season for the ruff. In wetlands across northern Europe and Asia, these medium-sized waders gather in marshes to form leks, which are small breeding areas used for courtship displays. Dominant males (also called independents) like the fancy fellow on our homepage, fluff up their colored and intricately patterned capes and collars and mock fight with each other. Their aim? Each wants to secure a prime spot on the lek to showcase his finery and entice watching females to choose him as a mate.Desktop Version
Mexican giant cardon cactus
Mexican giant cardon cactus
In the world of cacti, they don’t get any bigger than the cardon. Also known as ‘elephant cactus,’ this species can grow upwards of 60 feet and weigh in at 25 tons, with squat trunks and many branches. Despite the cardon’s massive size, it’s quite sensitive to frost, a trait which limits its range. The cardon primarily grows in the Baja Peninsula, where its night-blooming flowers attract species like the lesser long-nosed bat.Desktop Version
Paradise, found
Paradise, found
If your dream is to experience a tropical paradise that"s still largely untouched by people, you could do worse than a trip to Raja Ampat, an archipelago in the province of West Papua, Indonesia. Most of the region"s 50,000 inhabitants live on or around its four main islands, Batanta, Misool, Salawati, and Waigeo. The remainder of Raja Ampat is made up of roughly 1,500 smaller islands, cays, and shoals—astonishingly, hundreds of these tiny islands have yet to be explored by humans.Desktop Version
