Explorer of the sea
Explorer of the sea
This blue shark is swimming near the Azores, a Portuguese chain of islands about 850 miles west of mainland Portugal. The inspiration for the shark"s name comes from its back color, which can vary from a light blue to a darker shade. Its slender, tapered body is propelled through the water with agility and grace by a long tail fin that sweeps from side to side. Listed as "near threatened," blue sharks are found off the coast of every continent except for Antarctica, making them the most widely distributed of all sharks. Swift and powerful swimmers, blue sharks migrate long distances. It"s common for them to swim 1,200 to 1,700 miles or even farther, following the clockwise currents of the Gulf Stream in search of food, mates, and "just right" water temperatures.Desktop Version
Can you see the family resemblance?
Can you see the family resemblance?
In honor of Cousins Day, we"re hanging out on a limb with these four Javan tree frogs in Indonesia. Tree frogs are smaller than your average terrestrial frogs because they spend the majority of their lives perched in trees, and their weight must be fully supported by twigs and leaves. At the rounded ends of their froggy fingers and toes are disc-shaped adhesive pads that help them to maneuver about on trees. While most tree frogs (there are 800 species all over the world!) are green, brown, or gray, these Javans are bright and colorful. This is so they can blend into their jungle environs and avoid notice by predators such as snakes, spiders, bats, and owls.Desktop Version
Don’t get lost in there
Don’t get lost in there
Look closely at today’s homepage picture and you might spot some adventurous folks searching for the way out of this elaborate corn maze in Northern California. Corn mazes—known as ‘maize mazes’ in the UK—are a popular fall-time tradition that allows for much creativity. A Massachusetts farm draws visitors to its Tom Brady tribute maze, designed to look like the Patriots quarterback throwing a football. And a farmer in Illinois built a 6.5-acre maze shaped like a vintage Indy 500 race car. We’re still holding out for a corn maze inspired by search engines. Anyone game?Desktop Version
Penguin Awareness Day
Penguin Awareness Day
Let"s hear it for our poster penguin on Penguin Awareness Day. This cheerful specimen is an Adélie penguin, a species commonly encountered along the coasts of Antarctica this time of year. Breeding season for these birds begins by October, when they gather in colonies of thousands, coupling off and constructing nests made of stones.Desktop Version
Welcome to the drainpipe of the Pacific
Welcome to the drainpipe of the Pacific
We are standing here on the craggy Oregon coast looking out to Thor"s Well with the help of a photographer"s telephoto lens. Only the most daring of visitors would get this close to the gaping sinkhole at high tide. One misstep combined with a forceful surge from the raging Pacific Ocean, and into the plunging well we"d go.Desktop Version
A day for the dolphins
A day for the dolphins
We"re celebrating World Dolphin Day with a small pod of pantropical spotted dolphins. Award-winning photographer Christian Vizl captured this serene scene off the coast of Ixtapa, Mexico, where these cetaceans can be, er, spotted in abundance. As their name would suggest, pantropical spotted dolphins live in tropical and subtropical waters around the world. They"re the second-most common dolphin after the bottlenose and grow between 6 and 7 feet long. That may seem big if you were swimming next to one, but it"s really pretty small compared with the big kahuna of the dolphin family—the orca. Orca bulls can be up to 32 feet long and tip the scales at 11 tons. Let"s all take a moment today to spread the love of dolphins big and small and recognize their importance to our ecosystem. To see more of Vizl"s stunning nature photography, select the link below.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
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
Giving Tuesday
Giving Tuesday
These common terns sharing a fish have the right idea for today, which is Giving Tuesday. Held annually on the Tuesday after the US Thanksgiving, the global movement serves to encourage acts of generosity during the holidays, when consumerism seems to be the focus for so many. Giving Tuesday was founded in 2012 by New York"s 92nd Street Y in partnership with the United Nations Foundation. Originally observed only in the US, it"s grown into a worldwide celebration of generosity promoted by a newly independent organization. There are several ways you can participate: Donate to the cause of your choice, volunteer your time, or just do something nice—even sharing a fish counts.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
Mount Rainier National Park
Mount Rainier National Park
Mount Rainier is the crown jewel of its namesake national park, designated March 2, 1899, by President William McKinley. It was just the fifth national park in the United States. Beyond the mountain, the 369-square-mile park also includes valleys, waterfalls, old-growth forest, and pristine alpine meadows famous for summer wildflowers.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
Horse Head Rock, New South Wales, Australia
Horse Head Rock, New South Wales, Australia
You can lead a horse to water, but you can"t make it drink—unless, of course, you"re talking about Horse Head Rock, perched off the Sapphire Coast near Bermagui in New South Wales, Australia. This ancient formation, pictured here, seems as if nature itself has sculpted a mythical creature forever poised to drink from the sea. Estimated to be 500 million years old, the rock"s uncanny resemblance to a horse bending its neck is the result of wind and wave erosion. As one of the region"s oldest and most iconic landmarks, it attracts hikers, photographers, and nature lovers year-round. The best views are from the elevated track between Camel Rock and Murunna Point, while the more daring can scramble around from Camel Rock Surf Beach, though only safely at low tide.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

It s National Mushroom Month!
Is it just us or does this porcini mushroom look straight out of a fairy tale? We"re featuring this sweet "shroom today because September is National Mushroom Month, a non-official holiday inaugurated in 1992 as part of a governmental effort to promote mushroom farming in the US. Some of the biggest celebrations this month occur in Kennett Square, Pennsylvania, which is recognized as the Mushroom Capital of the World. The town of just 6,000 people cultivates around 500 million pounds of mushrooms each year, about half of the total US crop.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
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
Autumn in Piedmont
Autumn in Piedmont
This beautiful fall scene is in the Langhe area of Piedmont, one of the great wine regions in Italy. More specifically, we"re looking at the hills of Barolo, a town famous for its locally produced wine of the same name, made from Nebbiolo grapes. In addition to wine, Piedmont is known for its truffles, which are harvested this time of year. Piedmont chocolate is also highly prized. Bicerin, a popular coffee-chocolate drink from the city of Turin (which hosted the 2006 Winter Olympics), has been around since the 18th century. The piemontesi, as locals are called, know how to eat and drink. Salute!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

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

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
Illuminations on the Gulf of Poets
Illuminations on the Gulf of Poets
Each year on Aug 17, the northern Italian fishing village of Porto Venere is illuminated with more than 2,000 torches for the festival of the White Madonna, a tribute to the town’s patron saint. The lights extend onto this rocky spur, which juts into the Gulf of La Spezia, also known as the Gulf of Poets. With views like this, we can easily see how it inspired poets and artists throughout history–including Lord Byron, who is said to have swum across this body of water to visit fellow poet Percy Bysshe Shelley.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
