The tortoise and the finch
The tortoise and the finch
That’s a type of Darwin’s finch perched atop a giant tortoise on Isabela Island, the largest of the Galápagos Islands. The Galápagos form an archipelago more than 500 miles off the west coast of the South American mainland, and the islands are home to many species found nowhere else on earth. The bird is named, of course, for Charles Darwin, the naturalist who traveled here in 1835. His observations of several finch species and other wildlife endemic to the Galápagos contributed to his theory of natural selection, which he documented in ‘On the Origin of Species,’ a book that’s considered a cornerstone of biology. It was first published on this day in 1859.Desktop Version

Join us in celebrating World Water Day
The theme of this year’s UN-sponsored event, observed on March 22, is nature-based solutions for managing water resources. Organizers say that strategies like reconnecting rivers to flood plains and restoring wetlands have the potential to rebalance the water cycle and improve human health and livelihoods. Today we are proud to highlight the efforts of the Nature Conservancy, a global nonprofit working to conserve the lands and waters on which all life depends. Your support of their work makes a difference for people and nature.Desktop Version
A peek at an explosive peak
A peek at an explosive peak
We"re looking at Lassen Peak, a volcano also known as Mount Lassen, and its reflection in Manzanita Lake. This stunning scene can be found in Northern California"s Lassen Volcanic National Park, which was established on this day in 1916. The volcano erupted between 1914 and 1917 (with some activity as late as 1921), but these days the surrounding area is a calm destination of trails, lakes, and stark lava beds. One of the least visited parks, Lassen was the first national park in California to fully reopen after being closed for COVID-19, although it implemented some restrictions to park services and facilities. The park also includes acres of mud pots, hot springs, steam vents, and fumaroles to remind you of the heat that"s below you, including Boiling Springs Lake—one of the largest boiling lakes in the world at over 500 feet wide.Desktop Version
Travel Sunday: On the Ganges in Varanasi, India
Travel Sunday: On the Ganges in Varanasi, India
These floating candles are part of the Ganga Aarti ceremony, a nightly Hindu ritual here in Varanasi, which is a holy city for followers of Buddhism, Hinduism, and Jainism, all of which are ancient religions of India. Tourists join congregants who gather at the river’s edge as practitioners make offerings of light to the goddess Ganga, the river’s namesake. In addition to Varanasi’s religious significance, this diverse city in North India also draws tourists for its ornate temples, silks, and archaeological sites.Desktop Version
A stroll above the stratosphere
A stroll above the stratosphere
If this photo from 200-plus miles above Earth dizzies you, imagine how it felt to be Alexei Leonov on March 18, 1965. The Soviet cosmonaut achieved the first-ever extravehicular activity (EVA—but you and I just call it a spacewalk). He spent about 12 minutes outside the orbiting Voskhod 2 capsule. It was the ultimate risk: No one knew just what could happen to a human body in the vacuum of space. Near heatstroke, drenched with sweat, and with his suit dangerously inflating, Leonov barely made it back inside the airlock.Desktop Version
Across the great plains of Africa
Across the great plains of Africa
This time of year, from late January to early March, babies arrive on the Serengeti. At the height of the wildebeest calving season, thousands of calves are born every day. Moments after birth, these youngsters can walk, and in just a few days, they"ll be able to run fast enough to keep up with the herd. That"s a good thing. Calving season isn"t just a draw for safari tourists wanting a front row seat at the start of the circle of life, but also for predators like lions, cheetahs, and hyenas on the hunt for easy prey.Desktop Version
The dancing trees of Sumba Island
The dancing trees of Sumba Island
On the northern coast of Indonesia"s Sumba Island, a stand of mangrove trees appears to dip and sway to summon another dreamy sunrise. Walakiri Beach is gently sloped, so it"s easy for a visitor to walk out into the knee-deep water to examine the extraordinary transitional zone of a mangrove ecosystem. Mangroves thrive here at the boundary between land and sea, growing in coastal salt water and low-oxygen conditions where other trees would quickly die. Their complex root systems filter out the salt and form a strong natural defense against storm surges, rising sea levels, and coastal erosion. Mangroves also create aquatic nursery habitats that support a highly diverse range of juvenile fish and crustaceans.Desktop Version

Góða ólavsøku, from the Faroes!
The festival known as Ólavsøka spans several days, but officially July 29 is the big day of merrymaking in the Faroe Islands. What exactly are the Faroese people celebrating? Technically, they"re observing the death of Saint Olaf. The Norwegian King Olaf II is said to have died in battle on this day in 1030. A century later, he was sainted by the Catholic Church.Desktop Version
On the rebirth of the Olympic Games
On the rebirth of the Olympic Games
Today marks the 125th anniversary of the first modern Olympic Games, held in Athens in 1896—1,500 years after they were banned by the Roman emperor. (The original games were held at least as far back as 776 BCE and probably earlier.) The 1896 Games were held in the Panathenaic Stadium, in the shadow of the Acropolis of Athens, shown here. Those newly revived games of 1896 included athletes from 14 countries, with the largest delegations from Greece, Germany, France, and Great Britain. The 43 events included a marathon, tennis, cycling, fencing, shooting, Greco-Roman wrestling, and swimming. And while some things haven"t changed over the years, some were pretty different back then. Swimmers were taken out to sea by boat for the longer races and had to swim back to shore. Winners were given a silver medal (copper for second place), as well as an olive branch and a diploma.Desktop Version
Guiding ships to safety
Guiding ships to safety
National Lighthouse Day brings us to Port Clyde, Maine, where Marshall Point Lighthouse keeps watch over the Atlantic. Lighthouses have long played an important role in seafaring, and for many, they symbolize a simpler, more romantic way of life. Many lighthouses offer tours and some even let guests stay overnight, so they can get a feel for the life of lighthouse keepers who once tended the lights in the days of oil lamps.Desktop Version

Honoring the fallen
We’re here at Arlington National Cemetery with the ‘Old Guard,’ the 3rd United States Infantry Regiment and oldest active-duty regiment in the US Army. Each year before Memorial Day, as part of a ceremony known as ‘Flags In,’ members of the Old Guard place an American flag in front of each headstone at Arlington. Within four hours, more than 228,000 flags are placed at the headstones and thousands more at various memorials.Desktop Version
Where the glow of the holidays lingers
Where the glow of the holidays lingers
On the shores of Lake Lucerne and bestride the River Reuss, you"ll find the medieval Swiss city that shares the lake"s name. Emerging from a Benedictine monastery founded here in 750, Lucerne is today the largest town in central Switzerland. The central of three ancient, covered wooden pedestrian bridges of Lucerne"s Old Town has a unique feature. The interior of the Kapellbrücke (Chapel Bridge) is painted with religious scenes and allegories to edify those walking across it to the nearby St. Peter"s Chapel.Desktop Version

It’s National Dolphin Day!
We’re celebrating National Dolphin Day by heading to the waters offshore from Kaikoura, New Zealand, where a pod of dusky dolphins is surfacing along South Island’s Pacific Coast. The ‘dusky’ descriptor comes from the dark gray, sometimes black coloring on the marine mammal’s back. Dusky dolphins are found only in the Southern Hemisphere.Desktop Version
Gazing down on planet Earth
Gazing down on planet Earth
It"s Earth Day today and we are high above the blue marble looking down on the border between Arkansas and Mississippi. Those small, blocky shapes are towns, fields, and pastures, and the teal green is the mighty Mississippi River. Anyone who has flown in the window seat of an airplane and gazed down at Earth below might wonder why the colors in this image look so unreal. That"s because they are. This image was taken in 2013 by Landsat 7, a NASA satellite that uses thermal infrared sensors to help scientists better distinguish flora, fauna, water, and manmade objects. For almost 50 years, NASA has been using satellite imagery to understand how climate change and population growth are affecting our fragile planet. These satellites help NASA see where deforestation and wildfires are happening, where glaciers are melting, and how rising waters are encroaching on cities.Desktop Version
Protecting endangered giants
Protecting endangered giants
In honor of Wildlife Conservation Day, we"re looking at these two white rhinos strolling through the Amakhala Game Reserve in South Africa—with a friendly oxpecker bird on their tails. The large anklets they"re wearing are used to track the endangered animals and protect them from poaching. Both white and black rhinos live in open savanna, but the adult rhinos" only real predators are humans who hunt them for the illegal trade of their horns. Although they are known for being large, tough animals, rhinos are easily poached during their daily visits to the watering hole. Southern white rhinos now thrive in protected sanctuaries like the Amakhala Game Reserve. But the northern white rhino subspecies is believed to be extinct in the wild with only a few captive individuals remaining. Black rhinos have doubled from their low point over the past two decades, but still number only a fraction of their population in the early 20th century.Desktop Version
The Colosseum of Rome, Italy
The Colosseum of Rome, Italy
A photographer who goes by the name Paperboyo (real name Rich McCor) took this photo, and many more like it. Using paper cut-outs placed at just the right angles, McCor’s photos add an element of whimsy to the world’s famous landmarks. The project began when McCor was thinking of ways to photograph the iconic landmarks of London ‘in an original way.’ Spurred on by the enthusiasm of those who saw his photos, he quickly added more like these to his portfolio. As of this writing, there are no known incidents of a giant octopus taking over Rome’s Colosseum.Desktop Version

We approach from the Mediterranean to arrive at a 2018 European Capital of Culture: Valletta, Malta. This celebration of city-specific culture began in 1985, and since 2010 two cities have shared the title each year (Valletta shares the 2018 honors with Leeuwarden, in the Netherlands). Valletta, the southernmost capital of Europe, has a remarkable range of architectural styles throughout the city, from 16th-century churches to the ultra-modern Parliament House. Aside from its rich homegrown culture, Valletta reflects a variety of outside influences, including several jazz clubs and a Baroque music festival.Desktop Version
It s superb owl Sunday
It s superb owl Sunday
These two great gray owls look like they"re ready to play, which seems fitting on Super Bowl (or "superb owl") Sunday. Great grays are bigger than most other owls, with broad wings and long tails. But before you pencil them in at the offensive line, consider that most of their size comes from feathers—they"re relative lightweights, tipping the scales at under 3 pounds on average, less than most other large owls. They generally live in pine and fir forests with meadows nearby, hunting small rodents at night and avoiding areas with people. Great grays hunt by listening and watching from a perch, then swooping down on their prey—sometimes plunging into more than a foot of snow to make a diving catch.Desktop Version
New beginnings
New beginnings
Spring means more than just April showers and May flowers. It"s also the season when many baby animals are born. The rainy, warmer days bring new plant growth, which means nursing and foraging moms can provide their newborns with larger amounts of higher-quality food. It also maximizes the "growing season" for spring babies, giving them time to increase in size and put on fat before winter arrives.Desktop Version
Shadows on the solstice
Shadows on the solstice
Roughly 5,000 years ago, ancient inhabitants of the British Isles somehow dragged as many as 40 giant stones—the heaviest weighing an estimated 16 tons—onto this grassy plateau in what is now England"s Lake District National Park in Cumbria. They then grouped them into the stone circle at Castlerigg, seen here casting shadows from the low winter sun. Archeologists believe stone circles were arranged to align with solar and lunar positions. They were used in elaborate rituals to celebrate occasions like today"s winter solstice, the shortest day (and longest night) of the year in the Northern Hemisphere.Desktop Version
Bridges to the past
Bridges to the past
The story of this sandstone formation in southeastern Utah"s Natural Bridges National Monument begins around 10 million years ago. That"s when tectonic shifts began slowly lifting what is now the 130,000-square-mile Colorado Plateau above the surrounding plains. In ensuing eons, the Colorado River"s many streams eroded the elevated land, threading it with deep canyons. When water broke through one canyon wall into another canyon, sometimes a natural bridge like this one remained above the breach.Desktop Version

A good time in the Badlands
At the close of National Park Week, we arrive at Badlands in South Dakota. Our photo today shows a view from Castle Trail—at 10 miles round trip, it’s the longest marked hike in the park. Spring rain has revived the grasses across the prairie as the sun illuminates the pinnacle rock formations in the distance. Soon, grazing animals such as bison and pronghorn will begin feasting on the fresh crop of grasses. This is also a good time of year to spot some of the dozens of different butterfly species that live in the park and provide a delicate contrast to the park’s rugged landscape.Desktop Version
