Earthrise on Moon Day
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
Napping away New Year s Day
Napping away New Year s Day
This mountain hare is starting the year off right. It"s used to cold weather and high altitudes—and, since it"s nocturnal, it"s perfectly comfortable sleeping through an afternoon snowstorm in northeast Scotland. On New Year"s Day, humans in the US are more likely to be found in their natural habitat, the couch, dozing off or perhaps watching one of the college football bowl games on TV. Some more ambitious folks might be getting a jump on their New Year"s resolutions and exercising. First Day Hikes are part of an initiative led by state parks, with hundreds of free guided hikes offered in all 50 states. That sounds great, but maybe a little later. Right now, we think the hare has the right idea.Desktop Version
Halo around the sun
Halo around the sun
What do you call a rainbow formed by ice? An icebow, of course. Others call the phenomenon a halo, and we"ll admit it does have a mystical aura. Halos can occur when ice crystals suspended in the air refract light into a colorful ring around the bright sun. That"s what"s happening in the cold atmosphere here in the Ore Mountains along the Czech-German border. It"s a perfect complement to the snow angels you"re yearning to make in this pristine blanket of white.Desktop Version
The fantastic winter fox
The fantastic winter fox
Animals have many adaptations for winter weather, such as migration, hibernation, and growing thick fur. For the small but mighty Artic fox–the change in seasons means changing colors. Its thick fur coast transitions from brown and gray to a snowy white as a form of camouflage when colder temperatures arrive at its tundra habitat. Other animals that turn white in winter include the snowshoe hair, and several species of weasel–but we’re partial to this noble-looking fox. Stay warm, buddy!Desktop Version
Embracing the cold
Embracing the cold
We’re in St. Paul, Minnesota, for day seven of the Winter Carnival—an 11-day celebration of all the fun you can have during the cold winter months. In 1885, a journalist from New York who had visited St. Paul called it ‘another Siberia, unfit for human habitation.’ This news prompted the people of St. Paul to create the Winter Carnival, which debuted in 1886. When the temperature is cold enough, carnival organizers build a massive ice palace, whose ice-block walls frame the Landmark Center clock tower in our photo today.Desktop Version
The rainbow connection
The rainbow connection
April showers bring rainbows, and on April 3, the celebration of Find a Rainbow Day. The rainbow shown here is at Victoria Falls in southern Africa on the Zambezi River, at the border between Zambia and Zimbabwe. Scottish explorer David Livingstone named the falls in honor of Britain"s Queen Victoria, though it"s also still called by its indigenous Lozi language name, Mosi-oa-Tunya, which means "the smoke that thunders." According to some historical records, local villagers described the falls to Livingstone as "Seongo" or "Chongwe," which means "The Place of the Rainbow," since rainbows usually appear in the constant spray. Under a bright moon, the falls will produce a "moonbow."Desktop Version
The Kelpies statues in Falkirk, Scotland
The Kelpies statues in Falkirk, Scotland
The world’s largest equine sculptures, The Kelpies were built in 2013 in Falkirk, Scotland, as a tribute to the country’s horse-powered industrial heritage. Designed by sculptor Andy Scott, each steel statue is 100 feet tall and weighs more than 330 tons. They’re named for the kelpie spirits of Scottish folklore—shape-shifting water creatures said to favor the shape of a horse, but also thought to take human form.Desktop Version
A leafy seadragon in the waters off Wool Bay, Australia
A leafy seadragon in the waters off Wool Bay, Australia
Australia’s southern coast is leafy seadragon territory, so it’s the place to go if you want to see the camouflaged critter in its native habitat. This amazing specimen was photographed near Wool Bay. The leafy seadragon has evolved to resemble seaweed as a way to fool predators. It’s a relative of the seahorse, but isn’t quite the swimmer that its cousin is, so the camouflage gives it a big advantage.Desktop Version
A hidden jewel in Croatia
A hidden jewel in Croatia
Today we"re walking out into the winter wonderland of Plitvice Lakes National Park, the oldest and largest national park in Croatia. More than a million tourists per year flock to this central mountainous region, renowned for its cascading waterfalls and 16 turquoise-colored lakes. These wooden pathways meander for miles around and above the lakes, beside waterfalls and over streams and rivers, which disappear into the moss-covered earth only to burst through again somewhere downstream. In fact, the lakes are all interconnected by underground flows and are separated from each other by natural dams of travertine.Desktop Version
The Lena Delta Wildlife Reserve in Siberia, Russia
The Lena Delta Wildlife Reserve in Siberia, Russia
At 5,530 square miles, the Lena Reserve is one of the largest protected lands in Russia. This is a ‘false-color’ image of the massive Lena River basin, taken by the Landsat 7 satellite. The colors were created by capturing infrared, shortwave infrared, and red wavelengths—the combination of light waves enhances the view of various topographical features. The Lena Delta Wildlife Reserve is home to numerous vital bird species, and various terrestrial wildlife adapted to the rugged Siberian wilderness.Desktop Version
Into the woods
Into the woods
On this day in 1908, President Theodore Roosevelt declared 554 acres in Marin County, California, a national monument. William and Elizabeth Kent, who donated the land, insisted the monument be named after naturalist John Muir, the environmentalist known as the "father of the national parks." Part of the Golden Gate National Recreation Area, Muir Woods is best known for its old-growth coastal redwood forests, which make up more than half its land. The redwoods in the monument are 600-800 years old, on average, with the oldest being at least 1,200. The tallest tree is about 258 feet, though redwoods grow as high as 379 feet farther north. Redwoods are an important part of the forest ecosystem. They absorb and "strip" moisture from fog, which then drips into the ground, supporting the trees as well as other forest life.Desktop Version
Celebrating National Dentist Day
Celebrating National Dentist Day
If ever there was a perfect mascot for National Dentist Day, celebrated on March 6, it’s the crab-eating macaque. This individual was photographed cleaning its teeth in Malaysia’s Bako National Park. Crab-eating macaques are native to Southeast Asia and they have a proclivity for using tools to forage, eat, and even practice dental hygiene. Scientists have observed them using blades of grass, fibers, and feathers to floss between their teeth. Give this macaque a gold star!Desktop Version
The mountain of 30,000 sakura
The mountain of 30,000 sakura
Mount Yoshino ranks as one of the best places in Japan to immerse yourself in the spring cherry blossom season. Over 30,000 flowering Japanese cherry trees, or sakura, grow in four main groves on the hillside. Because the trees, some planted over 1,300 years ago, grow at different elevations, the cherry blossom front gradually moves up the mountain in a slow, fragrant wave as the season progresses. Peak bloom usually arrives between early and mid-April. Most years, crowds wander through the town of Yoshino, visiting its traditional temples and shrines, before admiring the profusion of cherry blossoms, a custom known as hanami. Of course, we can practice hanami virtually with pictures. But if you"re lucky enough to have a blooming cherry tree near you, we encourage you to pause and breathe the moment in.Desktop Version
A different kind of dive
A different kind of dive
Our homepage divers are descending the clear turquoise waters of a cenote on Mexico"s Yucatán Peninsula. A cenote is a sinkhole that"s created when limestone bedrock collapses and exposes the groundwater underneath, creating pools of fresh water that delight swimmers, and even cave divers like those on our homepage. They"re diving in "El Pit" cenote, part of a flooded cave system near Tulum. It"s one of thousands of cenotes documented on the Yucatán, and a popular spot for divers who come to swim through the brilliant sunbeams.Desktop Version
Flying high on National Bird Day
Flying high on National Bird Day
On National Bird Day, we"re looking at two red-fronted macaws. These birds are endangered, but they"re not hard to find at the Red-Fronted Macaw Nature Reserve in Bolivia, where this picture was taken. They"re easiest to spot during breeding season, which runs from November to May, and they usually fly in pairs or larger groups. National Bird Day is observed on January 5, which coincides with the end of the Christmas Bird Count—a citizen survey that looks at native bird populations in the US. National Bird Day puts the focus on birds around the world, especially those threatened with extinction due to the pet trade, habitat loss, and climate change.Desktop Version
A towering view of the Pale Mountains
A towering view of the Pale Mountains
Behold the Tre Cime di Lavaredo, some of the most iconic peaks of the Dolomites range in the Italian Alps. The Dolomites, aka the "Pale Mountains," are named for the light-colored stone (dolomite) of the jagged range. This is the view from the highest point of a trail that encircles these three dramatic peaks. Usually mobbed with tourists in the summertime, autumn and spring offer a chance for a more tranquil amble along the 6-mile trail. The hike manages to reveal one stunning view after another with each turn of the route. Along the way, the hiker will pass three "rifugios," traditional Alpine shelters that offer drinks and meals, and even beds to stay the night.Desktop Version

For Waitangi Day, we’re on New Zealand’s South Island, where a limestone formation known as the Pancake Rocks buffers the land and sea. Waitangi Day is New Zealand’s national day, established to commemorate the signing of the Treaty of Waitangi on February 6, 1840. The document was signed by representatives of the British Crown and some 500 Māori chiefs to establish British law on the islands. The treaty also created the framework for political relations between New Zealand’s government and the indigenous Māori people. It’s considered New Zealand’s founding document and a cornerstone in the country’s history.Desktop Version
It’s Siblings Day!
It’s Siblings Day!
These two young elephants in Kenya’s Amboseli National Park may not be siblings, but young African elephants from the same herd are raised as if they are all related. Adult elephants pitch in to raise the little ones, even if they’re not the parents. Keep this supportive family-like structure in mind today, as it’s Siblings Day. Even if you don’t have any siblings in your life, there’s probably somebody you think of as being close enough to be a sibling. So, let them know you’re thinking of them today.Desktop Version

Lightning strikes are common during the summer monsoon in southwestern US states and northwestern Mexico. In Arizona and New Mexico, powerful thunderstorms roll in most every afternoon from early July until mid-September. Here, in the Sonoran Desert north of Tucson, Arizona, severe weather over saguaro cactus makes for a dramatic scene.Desktop Version
A cozy winter village
A cozy winter village
When snow blankets the steep slopes of the Pyrenees—the mountain range that forms a natural border between Spain and France—the cozy Spanish village of Benasque offers a cheerful refuge on a winter"s eve. Beautifully preserved Romanesque and Renaissance manors and churches line the narrow cobblestone streets, and it"s easy to feel as though you"ve stepped back in time. Aside from these cultural charms, most visitors come to Benasque for outdoor adventure. Surrounded by the highest peaks of the Pyrenees, the Benasque Valley receives heavy snowfall and is a popular skiing destination. Summer attracts even more visitors to the area, when hiking, mountain biking, paragliding, and river rafting are big draws.Desktop Version

This beautiful lake in northwestern Iran has had a rough couple of decades. Until around 1995, Lake Urmia was one of the 10 largest saltwater lakes on Earth, and the center of a thriving resort scene. Then drought, rising temperatures, water overuse, and the building of a causeway across the lake reduced it to less than 10% of its size by the 2010s.Desktop Version
