Frozen beauty
Frozen beauty
Located on the North Saskatchewan River, Abraham Lake is an artificial lake and Alberta"s largest reservoir. Even though it"s man-made, it takes on the blue color of other glacial lakes in the Rocky Mountains. In winter, the lake draws nature photographers interested not just in the wildlife and spectacular landscape, but also the lake"s odd appearance when it freezes over. Bacteria on the lake bottom feed on dead organic matter and release the methane bubbles you see here. When the surface water freezes, the bubbles get trapped, creating a photographer"s dream. They may be beautiful, but these frozen bubbles can be dangerous because they"re highly flammable. If you happen to be lighting a match nearby, you"ll want to watch out or the released methane could explode. The bubbles aren"t so friendly to the environment, either; methane in the atmosphere is a major part of global greenhouse gas emissions, which contribute to climate change.Desktop Version
Opt outside today
Opt outside today
Instead of rushing to the mall today for Black Friday deals, perhaps you could make it a Green Friday and find a treasure in a nearby park or wilderness like the Maroon Bells near Aspen, Colorado, pictured here. A few years ago, outdoor retailer REI made news by closing its doors on the biggest shopping day of the year and encouraging its employees and customers to "Opt Outside" by spending time with their loved ones instead. While there is still no shortage of shopping options available to the intrepid Black Friday deal-hunter, a growing number of organizations have gotten behind this concept of Green Friday. And let"s face it, after all that turkey and pie yesterday, you could probably use a nice walk. You can always shop online at work on Cyber Monday ;)Desktop Version

Satellite image of sand and seaweed in the Bahamas
We have NASA’s Landsat program to thank for this rare view of the Atlantic Ocean in the Bahamas, as captured by satellite. The patterns you see are sand and seaweed beds that have been sculpted by ocean currents. That dark spot? It’s called the Tongue of the Ocean. The tongue is a deep, dark trench that separates the islands of Andros and New Providence in the Bahamas and connects to a larger geological feature known as the Great Bahama Canyon.Desktop Version
A magnificent monolith
A magnificent monolith
Towering more than 650 feet, El Peñón de Guatapé (The Rock of Guatapé) is an inselberg, which is geologist-speak for a stone monolith that stands alone amid relatively flat surroundings. This huge rock is found in northwest Colombia, a region once inhabited by the Indigenous Tahamí people, who are said to have worshipped El Peñón, as many locals now call it. Probably because it"s so smooth, no one is known to have climbed the rock until 1954, when a small group of friends scaled it by wedging a series of boards into a vertical crack. It took them five days to reach the top.Desktop Version
Stari Most in Mostar, Bosnia and Herzegovina
Stari Most in Mostar, Bosnia and Herzegovina
To celebrate Independence Day in Bosnia and Herzogovina we’re in Mostar, a city on the banks of the Neretva River. This bridge that joins the two sides of the city is called Stari Most, or ‘Old Bridge.’ The original stone bridge was built in the 16th century but destroyed in 1993 during the Bosnian War. Reconstruction began in 2001, using local materials and even some stones from the original bridge. The new ‘Old Bridge’ was completed in 2004.Desktop Version
Up on the glacier
Up on the glacier
The Athabasca is the most-visited glacier in North America. Located in Canada’s Jasper National Park, it’s one of the six ‘toes’ of the Columbia Icefield, a natural feature of the Canadian Rockies. The Athabasca has receded by nearly a mile in the past 125 years, losing about 16 feet of ice each year. And that"s not all that"s moving in the Columbia Icefield—there"s also an icefall that travels downslope (the way a waterfall would) between 50 and 400 feet per year.Desktop Version
Travels to the Oregon deep
Travels to the Oregon deep
We"re looking out on the deepest lake in the US. Crater Lake, the centerpiece and namesake of the only national park in Oregon, goes down to depths of 1,943 feet—that"s enough room to stack three-and-a-half Washington Monuments on top of each other. Fed mainly by snowfall, this pristine, crystal blue lake came into the world with a bang. Sometime around 5700 BCE, Mount Mazama erupted, losing roughly 3,000 feet of its height. The volcano blew out so much molten rock that it left a giant depression that gradually filled with water, giving us this serene scene today.Desktop Version
A legend and a legendary home
A legend and a legendary home
To celebrate Sant Jordi’s Day today, we’re studying the intricate façade of Casa Batlló in Barcelona, Spain. The holiday is the Catalan celebration of Saint George’s Day, which is observed throughout Europe. According to legend, Jordi (Catalan for ‘George’) saved a princess from the clutches of a terrible dragon. After rescuing her, the knight gave the damsel a red rose, which has become an important symbol of the holiday in Catalonia. As it happens, Spaniards also celebrate April 23 as Book Day, marking the anniversary of the death of Miguel de Cervantes, the famous 16th- and 17th-century Spanish writer. So here in Barcelona, both roses and books are given to loved ones on Sant Jordi’s Day, while music and dancing fill the streets. We might pause in our revelry to spend some time taking in Casa Batlló, designed by Spanish architect Antoni Gaudí. The building is heavily inspired by Sant Jordi’s legend, with red roses on the balconies, and a roof made to look like dragon scales.Desktop Version
Into the woods
Into the woods
Catching a glimpse of a deer makes the world go suddenly quiet. One clumsy move, even a gasp, could send these two white-tailed deer, with a flash of their namesake tails, deeper into the woods. But if you live between southern Canada and South America, chances are good you"ll get another opportunity to see these native deer. They live throughout the United States, save for parts of the Far West, and thrive in a variety of habitats—forests, grasslands, even city suburbs. This doe and fawn were photographed in Wisconsin, a state that picked this locally abundant and economically important ruminant as its state wildlife animal back in 1957. So, why isn"t Wisconsin called "The White-Tailed Deer State"? Take the quiz to find out.Desktop Version
Groundhog Day arrives—beyond a shadow of a doubt
Groundhog Day arrives—beyond a shadow of a doubt
Do you think this hoary marmot in Alaska’s Denali National Park is wondering whether its relative, Punxsutawney Phil, saw his shadow today? Groundhog Day is an American tradition that originated among the Pennsylvania Dutch, but groundhogs aren’t the only animals believed to predict the weather. It’s said you can predict the severity of an upcoming winter by examining the stripes on a woolly bear caterpillar’s back. And in Germany, folks once looked to the badger to forecast the coming of spring. But no furry prognosticator of the weather has gained as much fame as Punxsutawney Phil. Perhaps we have Bill Murray to thank for that? (Be right back, got to cue up Murray’s film ‘Groundhog Day.’) Say, do you ever have déjà vu? Wait, did we just ask you that?Desktop Version
Sailing across the ice
Sailing across the ice
These snowkiters are competing at a tournament in Novosibirsk, Russia. Like kiteboarding on liquid water, the sport of snowkiting uses a parachute-like foil kite, which catches the wind and pulls the boarder along a frozen, snowy landscape. The sport wasn’t invented here in Siberia, but when January sends the mercury plunging, the freezing temperatures create ideal conditions for the sport.Desktop Version
Take the stairs
Take the stairs
If you want to celebrate Take the Stairs Day in style, look no further than China"s Tianmen Mountain (literally Heaven"s Door). About 5,000 feet above sea level, the hole in the mountain is the highest naturally formed arch in the world. Originally a cave, it became an arch in 263 CE when the back side of the mountain collapsed, creating the dramatic opening we see today. You"ll have to climb 999 steps to make it to the top, but we promise the view is worth it.Desktop Version
Time to count some birds
Time to count some birds
Before the 20th century, some North Americans organized ‘Christmas side hunts’ in which participants would choose sides, then compete to bag as many birds as possible. In 1900, ornithologist Frank Chapman suggested a bird census instead, and the Christmas Bird Count (CBC) was born. The annual count is sponsored by the National Audubon Society. This year, the CBC runs from today through January 5, 2019, giving citizen scientists across North America time to join in, get outside, and spot some birds. The data collected is used to gauge the health of various bird populations–this information is then used to focus conservation efforts on particular species and geographical areas.Desktop Version
Ready for takeoff
Ready for takeoff
Anybody with a camera can celebrate Nature Photography Day with us today. That element of inclusion is one of the main points of this observance. Chances are your mobile device has a camera, so you’re already equipped to participate. And even if you live in the deepest reaches of the urban jungle, somewhere near you is a place where you can get a dose of nature—a park, for example, or even the planter box on your fire escape. Go to that spot with your camera, and start snapping photos. They don’t have to be works of art. It can be an exercise in paying attention to the natural world, and maybe—just maybe—you’ll end up with something like this shot of a seven-spot ladybug, wings unleashed and about to take flight. Have fun!Desktop Version
The Zugspitze: Germany s highest point
The Zugspitze: Germany s highest point
Welcome to the snowy Bavarian Alps, where the mountain called the Zugspitze (TSOOG-shpit-seh) casts a cold shadow over the Eibsee, a small and serene alpine lake. Situated on the border with Austria, the peak is Germany"s highest point at almost 10,000 feet above sea level, towering over the lakeside village of Grainau.Desktop Version
What does the fox dream?
What does the fox dream?
We"re sure you could just squeeze this snoozing Arctic fox like a stuffed animal, but we wouldn"t advise it. These cute little fuzzballs can be ferocious hunters. In fact, the Arctic fox is one of the most prolific predators on the tundra, preying on lemmings, voles, rabbits, birds (often with a side of eggs), and other small critters that cross its adorable path. But right now, our Arctic fox is happy to curl up with its tail and get some shut-eye—by forming a ball with its body, the fox is exposing the least possible surface area to cold air, helping to conserve heat no matter how low the mercury dips.Desktop Version
A crane for good luck in today’s big game
A crane for good luck in today’s big game
It’s Super Bowl Sunday and this Japanese crane looks like it’s getting into the spirit of things. Also known as the red-crowned crane, the species is among the rarest cranes in the world. It’s known in some cultures as a symbol of luck and longevity, making it an ideal football mascot. This particular crane seems to have a pretty good punting leg, to boot. Other animals that have served as good luck symbols around the world include the pig, the mandarin duck, and the albatross. Do you have a good luck charm?Desktop Version
Once upon a time there was a bridge…
Once upon a time there was a bridge…
Although this stone bridge, known as Saut de Brot, looks right out of a fairy tale, it serves a very practical purpose. It connects walking trails on each side of the Areuse Gorge, offering safe passage to hikers exploring the lush Brot-Dessous area in western Switzerland, a predominantly French-speaking region of this multilingual country. It"s not known when the bridge was built exactly, though it"s thought to be a recent construction. But if that"s true, how do we not know who built it? All this mystery leads us to suspect it"s the work of helpful gnomes and fairies living deep in the Swiss woods. The end.Desktop Version
Celebrate International Women’s Day
Celebrate International Women’s Day
On the day before the 2017 celebration of International Women’s Day, the statue called ‘Fearless Girl’ was unveiled in the Financial District of New York. Staring down the ‘Charging Bull’ statue with resolute defiance, ‘Fearless Girl’ immediately resonated with people around the world as a symbol of women taking positions of leadership. The statue was initially meant as a temporary installation, but many have called for her to become a permanent fixture.Desktop Version
Once in a pink moon
Once in a pink moon
We"re seeing a vivid "pink moon" rise above St. Michael"s Mount—a granite-encrusted isle connected to the rugged peninsula of Cornwall, England, by sandy flats and a man-made causeway that submerge at high tide. The same order of monks that established France"s Mont-Saint-Michel built a church and priory here in the 12th century. In ensuing centuries of war, the insular monastic outpost was fortified into the imposing castle we see today. Privately purchased in 1659, the mount was opened to the public in 1954—and is still managed by members of the family that bought it over 350 years ago.Desktop Version
These laurels are hardy
These laurels are hardy
Go back 15 million years and you"d find most of Southern Europe looking like this fantasy forest: thick, scrubby underbrush canopied by wizened laurel trees. An epoch or two of human agricultural advances cleared those ancient woods, but patches persist on a few temperate Atlantic islands—especially here on Madeira, a Portuguese-held island off northwest Africa.Desktop Version
To Sua Ocean Trench
To Sua Ocean Trench
This majestic swimming hole on Samoa"s Upolu Island sits just inland from the coast. It was formed when the roof of an ancient lava tube collapsed, exposing the 98-foot-deep teal-blue pool. This is the largest of many such tide pools and blow holes formed in the area thousands of years ago. An underground cave system connects this swimming hole to the nearby ocean, and the water rises and falls with the tides.Desktop Version
A Christmas market with a long history
A Christmas market with a long history
We think even Scrooge would delight in the Frankfurt Christmas Market, or Christkindchesmarket (gesundheit!), a tradition that’s been traced back to 1393. Here you can shop for goods from artisans, binge on marzipan candies, and sip a warm cup of mulled wine. Locals can even shop for Christmas trees, a tradition that is said to have originated in this part of the world. The modern Christmas tree tradition as we know it started in the 15th and 16th centuries in northern Germany and Livonia (present-day Estonia and Latvia). It’s believed the Protestant reformer Martin Luther was the first to add lighted candles to an evergreen. Sidenote: That had to be a fire hazard, right?Desktop Version

Earthrise on Moon Day
Only two dozen people have ever personally witnessed the Earth rising over the lunar surface: the crews of Apollo 8 through 17. Those 24 astronauts are also the only humans to leave low-Earth orbit and see the "dark" side of the moon—and only 12 of them walked on its surface.Desktop Version
Field of Light at Sensorio by Bruce Munro
Field of Light at Sensorio by Bruce Munro
Artist Bruce Munro was camping at Uluru (aka Ayers Rock) in Australia in 1992 when he envisioned the art installation on today"s homepage. Titled "Field of Light," it"s currently on display at a venue called Sensorio in Paso Robles, California, the latest stop in a tour of sites around the world. At Sensorio, a new arts center that bills itself as representing "the intersection of art, technology and nature," visitors will find 58,800 solar-powered spheres, lit by optical fibers, that change color. When the sun sets, the fibers illuminate, creating a shimmering, interactive landscape in the meadow. The art installation changes a bit at each site, but Munro tells reporters, "The one constant is that it does make people smile."Desktop Version
