Since most large social gatherings have been postponed or canceled, we"re bringing the Armed Forces Day air show to you, courtesy of the US Air Force"s demonstration squadron, the Thunderbirds. In recent weeks, the Thunderbirds have joined with the Navy"s Blue Angels air squadron to conduct formation flights over several American cities as a salute to essential workers and health care personnel on the front lines of the COVID-19 pandemic. The two services are flying over some cities together and others separately. In a press release, Air Force Lt. Col. John Caldwell, the Thunderbird commander and lead pilot, said, "We are honored to fly over these cities in a display of national unity and support for the men and women keeping our communities safe."Desktop Version
Hiking the High Trestle Trail
Hiking the High Trestle Trail
The unique 130-foot-tall bridge you see here is just a small part of a longer 25-mile trail that connects five small towns in central Iowa. The High Trestle Trail is a rail trail—a decommissioned railroad track that’s been turned into a multiuse trail—and it follows the path of an old Union Pacific Railroad freight line. The rail-to-trail movement began in the 1960s when many railroad tracks began to be removed and people noted that the relatively flat rail corridors were perfect for hiking and biking trails. We can now enjoy thousands of miles of rail trails throughout the US. So today, on National Trails Day, find a trail near you and get outside to celebrate.Desktop Version
In Sicily, history is everywhere
In Sicily, history is everywhere
Today we"re in Montalbano Elicona on the island of Sicily. The town is known for the very old castle at the crest of the hill, as well as the quaint medieval village below. It"s no wonder that Montalbano Elicona has been called one of the most beautiful towns in all of Italy. The castle itself was built in the early 13th century by medieval power broker Frederick II of Swabia. He wore many hats, including King of Sicily, Holy Roman Emperor, and—as far-fetched as it sounds—King of Jerusalem, a title he claimed after conquering that city during the Sixth Crusade. The castle was originally designed as a fortress, but it also served as a summer residence for Frederick and rulers who followed him.Desktop Version

There once was a lighthouse from...
Nantucket is the island home of about 12,000 people. But venture to its sandy northern reaches, composed of narrow sand spits and only accessible via 4x4 vehicles, and you might not bump into many folks on your way to this historic—and still very important—lighthouse.Desktop Version
Red squirrel
Red squirrel
Shhh, it"s sleeping. But don"t confuse that with hibernating. A tree squirrel, like this red squirrel in Scotland, doesn"t hibernate during the winter. Hibernating is more of a ground squirrel trait. But the red squirrel is particular about where it sleeps, mostly building its nest, or drey, high above the ground in the cavity of an evergreen tree. Nests are often lined with soft materials such as leaves, moss, and grass. This little sleeper is using its bushy tail to keep warm, with the help of some lichen and pine needles.Desktop Version

Not far downriver from Montreal, where the banks of the St. Lawrence River widen as it approaches the Atlantic, lies Quebec"s picturesque and often chilly capital. Quebec City, one of the continent"s oldest European settlements, is often called the most European city outside Europe. It"s the only North American city outside Mexico whose fortified walls still stand, and its winding streets showcase a French-tinged exemplar of old Romantic architecture (typified by the steep-roofed Château Frontenac in the photo"s foreground).Desktop Version
Lights, camera, Sundance
Lights, camera, Sundance
The Sundance Film Festival begins today in Utah, bringing glitz and glamour to the ski town of Park City. When it first launched in 1978, the goal of the festival was to highlight American-made films and attract filmmakers to Utah. Robert Redford has long been involved in the festival, serving as chairman at the first event and in the years since, helping it become the media extravaganza it is today. In 1984 Redford’s Sundance Institute took over management of the festival, hence the ‘Sundance’ name, which comes from the name of the character he played in ‘Butch Cassidy and the Sundance Kid.’ In its 41-year history, Sundance has become perhaps the premier showcase for American independent and documentary film. We look forward to seeing what innovative new films steal the limelight in 2019.Desktop Version
‘The memory of Abraham Lincoln is enshrined forever’
‘The memory of Abraham Lincoln is enshrined forever’
The iconic Lincoln Memorial on the National Mall in Washington, DC, is chock full of symbolism and details for eagle-eyed observers to discover. Dedicated on this day in 1922, the landmark has 36 columns, representing each of the states in the Union at the time of Lincoln’s death. The president’s pose was designed to represent both his strength and compassion (one fist is clenched, the other at rest), and even the building materials were sourced from locations significant to his life and legacy. Look closely at the inscription on the wall of the north chamber and you’ll even spot a typo in the text of Lincoln’s second inaugural address, where the sculptor carved ‘EUTURE’ instead of ’FUTURE.’ Oops! The inscription has since been corrected, but the original mistake remains discernable.Desktop Version
A sleeping green giant
A sleeping green giant
We"re looking down on Chu Dang Ya, an extinct volcano that last erupted millions of years ago. Located in Gia Lai province in the Central Highlands of Vietnam, Chu Dang Ya means "wild ginger" or perhaps "tough ginger root" in the local Jarai language. The volcano provides fertile soil for crops such as pumpkins, sweet potatoes, taro, and more. Among the best times to visit this rural gem is at the beginning of the rainy season, in late April and early May, and as the rains wind down in November. That"s when Chu Dang Ya takes it up a notch—its hillsides erupt with sunflower and other wildflower blooms along roadways, dirt paths, and fields.Desktop Version
Colorful cows of the reef
Colorful cows of the reef
These brightly colored parrotfish are swimming off the coast of Negros Oriental province in the Philippines. There are dozens of species of parrotfish and they live in abundant numbers in the world"s tropical seas. These thick-bodied fish have large scales and a beak of fused teeth they use to diligently scrape delicious algae from reefs and rocks. Some also eat coral, which they grind up with plate-like teeth in their throats. Researchers say parrotfish play a critical role in the health of coral reefs by eating algae that can choke off coral growth. They also help replenish the white sandy beaches near these tropical reefs. How? After parrotfish digest the edible parts of coral, they excrete what"s left as sand—a lot of sand. In some species, a single parrotfish can poop almost 1,000 pounds of pearly white sand each year. But never mind that—some trivia is best not to dwell on.Desktop Version
It s Computer Science Education Week
It s Computer Science Education Week
Are we looking at some sort of steampunk time machine? Not quite, but these clock-like rotors did help alter the course of history. The action took place during World War II at England"s Bletchley Park, a country estate that served as a top-secret facility. An assembled team, including the pioneering computer scientist Alan Turing, developed this device, known as a Bombe machine. It was instrumental in cracking the Germans" "uncrackable" Enigma code, which was used for encrypting secret messages in German war operations. The Enigma code was itself generated by a rotor-driven machine that re-scrambled the code each day—so the Bombe mirrored those mechanics to keep up with the changing encryption. Insights the Bombe and other programmable machines provided into enemy military plans helped to speed the Allies" eventual triumph—some even argue that the codebreakers" efforts won the war.Desktop Version
A lofty lighthouse and a little ocean spray
A lofty lighthouse and a little ocean spray
The Farolim de Felgueiras (Lighthouse of Felgueiras) you see here has withstood relentless waves for around 135 years. It offered its solitary warnings to ships approaching Porto, Portugal"s second-largest city, beginning in 1886 until it was finally deactivated in 2009. Even though it"s no longer operational, it"s still a well-known local landmark. It offers sightseers a beautiful view, and maybe a little ocean spray, from its perch overlooking the mouth of the Douro River where it flows into the Atlantic.Desktop Version

A sizzling summit hides in the clouds
Seen here with its explosive summit socked away in the clouds, Mount Etna towers over the Italian isle of Sicily as the tallest volcano in Europe—and maybe the crankiest, given its near-constant eruptions. The island peak has been highly active for perhaps half a million years and can still be counted on for a spectacular eruption now and then. This photograph shows Etna erupting in 2013, but it blasted back into life again in February 2021, sending lava, ash, and smoke into the sky for weeks.Desktop Version

When the Georgia Aquarium in Atlanta opened in 2005, it was the largest in the world. (China’s Chimelong Ocean Kingdom now takes the prize.) If you are spending time in Atlanta, even on a layover during holiday travel, make your way to the amazing exhibits in the Georgia Aquarium. Perhaps the most distinctive of the aquarium’s exhibits is its giant tank of whale sharks. The 6.3-million-gallon tank houses four whale sharks—the world’s largest fish—as well as four manta rays and thousands of other fish. The tank is so massive, the rest of the aquarium was designed around it.Desktop Version
Celebrating Flag Day: ‘O long may it wave’
Celebrating Flag Day: ‘O long may it wave’
June 14 is Flag Day, which commemorates the official adoption of the American flag in 1777. Our nation’s first flag had 13 stars and 13 red and white stripes to represent the original 13 colonies that broke from British rule. The stars were arranged on a blue background to represent a ‘new constellation.’ In 1795, as Vermont and Kentucky joined the Union, two more stars and two stripes were added. It was this version that served as muse to poet Francis Scott Key, who penned the poem that would later serve as the lyrics for ‘The Star-Spangled Banner.’ He wrote the words after watching the flag fly over the Battle of Baltimore during the War of 1812. The flags in our image are rippling over Liberty State Park in Jersey City, New Jersey.Desktop Version
Why do elephants hide in trees?
Why do elephants hide in trees?
…Because they"re so good at it. Although none are as skilled at self-concealment as this specimen from the Loxodonta genus of African elephants—namely the species laprofolis, better known as the common chia elephant. While it"s the well-known habit of other pachyderms to paint their toenails red and hide in cherry trees, the chia elephant"s defense is even more unique: After a nice roll in the mud, the elephant charges through patches of seeding chia plants, picking up thousands of seeds that stick on its grooved hide. In under a week—just add water!—the seeds sprout and develop into dense, leafy growths that allow the elephant to conveniently camouflage itself as it wanders the savanna. The curious creature has even been reported to disguise itself as a houseplant, duping homeowners into hosting a literal elephant in the room.Desktop Version
Here there be dragons
Here there be dragons
Welcome to Indonesia’s Komodo National Park, founded in 1980 to protect the Komodo dragon—a monitor lizard that evolved in this insular environment to be much larger "scale" than its fellows. Found only on the islands we see here—Komodo and Padar—and a handful of others nearby, it"s the biggest lizard walking the Earth today. Not only walking but sprinting: Since adult Komodo dragons often prey on swift Timor deer, you"ll sometimes see a dragon in a dead sprint after its would-be dinner, reaching up to 13 miles an hour.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
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
Happy New Year!
Happy New Year!
Welcome to 2024! Did you stay up late to ring in the new year? If so, we wouldn"t blame you for sleeping in like this red fox in Abruzzo, Italy. Whenever you wake up, New Year"s Day is a great opportunity for reflection, planning, and a sense of renewal for the year ahead. January 1 has been a big day since the Julian calendar was widely adopted in 45 BCE—modified in 1582 by the Gregorian calendar to better calculate for leap years. Whether you"re watching a parade, attending a sports game, taking a chilly dip, or writing resolutions, we hope it"s the beginning of a great year to come.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
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
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
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
