Happy Independence Day!
Happy Independence Day!
Across the United States on July 4, we celebrate the adoption on this day in 1776 of the Declaration of Independence, one of the best break-up letters ever written. In this pronouncement, the Second Continental Congress put Great Britain on notice that the 13 American Colonies were no longer subject to its rules or rulers and were forming a new country, the United States of America. Declaration signers, recognizing the importance of the moment and the message, anticipated that generations later, we would remember and celebrate "from one end of this continent to the other." The celebration we"re looking at here is at the National Mall in Washington, DC, with fireworks rising above the Lincoln Memorial and Washington Monument, and reflected on the Potomac River.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
Atrani, Amalfi Coast, Italy
Atrani, Amalfi Coast, Italy
With its red clay roofs and pastel buildings Atrani shines above a sparkling sea on the Amalfi Coast in southwest Italy. Just 800 people get to call Atrani home, the rest of us can only hope to visit one of the country"s smallest towns, walking its narrow roads as we admire the small houses perched above the beach. The traditional fishing village is part of the Costiera Amalfitana UNESCO World Heritage Site, and it has kept its traditional characteristics alive. It is a perfect Mediterranean getaway to soak up the sun and enjoy local seafood at a waterfront cafe.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 National Mushroom Month!
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
Ski touring in Austria
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
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
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
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
World Frog Day
World Frog Day
World Frog Day is celebrated every year on March 20, a chance to consider the world"s most famous tailless amphibian. The star of fairy tales, cartoons, films, and TV shows, the charismatic and clearly photogenic frog accounts for almost all amphibian species. Frogs have been around for more than 200 million years, and although they live in both warm and cold places, most reside in tropical rainforests.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

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
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
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
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

Milky Way over Zabriskie Point, California
This iconic view of the Milky Way from Zabriskie Point in California will draw crowds of photographers and tourists this weekend, as the Death Valley Dark Sky Festival begins. Death Valley National Park offers some of the best stargazing in the US and has been awarded the highest ‘gold tier’ rating by the International Dark-Sky Association.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
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
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
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

A bull, some flowers, and a stratovolcano
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

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
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
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
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
