A march toward a dream
A march toward a dream
For Martin Luther King Jr. Day, we"re going back to August 28, 1963, to the March on Washington. Among those in the front line of demonstrators are baseball great Jackie Robinson and bus-boycott activist Rosa Parks, both towering figures in the civil rights movement. Later this day, the Reverend Martin Luther King Jr. would deliver his "I Have a Dream" speech in front of a quarter-million protesters packed onto the National Mall. The speech is considered among the best in American history and a defining moment in the fight for civil rights. King was just 34 years old.Desktop Version
What are these creatures?
What are these creatures?
No, this isn"t a still image from a sci-fi space opera. We"re offshore of Coffs Harbour, New South Wales, Australia, watching a Glaucus atlanticus, aka "sea swallow" or "blue sea dragon," snack on the poisonous tentacles of a Porpita porpita, aka "blue button." At the tips of the blue button"s tentacles are stinging cells called nematocysts, but the venom doesn"t deter the sea swallow. Instead, once the sea swallow ingests the blue button"s poison, it stores the venom in the tips of its own feather-like fingers called papillae. Would-be predators should think twice before biting the sea swallow. The poison concentrated in its papillae can kill a predator in seconds. If you come across either of these creatures washed ashore, don"t touch! While the stings aren"t deadly to humans, they can cause skin irritation.Desktop Version
Cherry blossoms spring to life
Cherry blossoms spring to life
The National Cherry Blossom Festival is always a highlight of spring in our nation"s capital. It"s timed for the peak bloom date (usually the last week in March or first week of April) when most of the blossoms are open on the cherry trees that surround the Tidal Basin. The trees were originally a gift from Japan, planted in Washington in 1912. While some Cherry Blossom Festival events are virtual this year, the trees will decorate the city as usual—just as they do in this photo framing the Jefferson Memorial. This year"s festival began on March 20 and runs until April 11. It includes in-person tours and activities visitors can do on their own, as well as virtual viewings and an online Celebration Show that debuts on April 9.Desktop Version
‘Hello’ from zero degrees longitude
‘Hello’ from zero degrees longitude
This laser projected from the Royal Observatory at Greenwich, in London, England, marks the prime meridian, dividing Earth’s Eastern and Western Hemispheres and helping travelers to chart their courses by establishing a universally adopted 0 degrees longitude. The meridian itself is essentially an imaginary line, arbitrarily placed. By the early 19th century, most maritime countries had established their own prime meridians to aid in navigation. But on this date in 1884, delegates from 25 nations met at a conference in Washington, DC, where they established Greenwich as the international standard for mapping and timekeeping. The decision made sense, as the Greenwich meridian was already widely used. But there was one holdout: France abstained from the vote and used its own prime meridian for several decades before eventually joining other countries in recognizing the Greenwich meridian.Desktop Version
Just a couple of yellow-billed hornbills
Just a couple of yellow-billed hornbills
Southern yellow-billed hornbills live in the dry savannas of southern Africa. These two were photographed in South Africa"s Kruger National Park, one of the largest nature preserves on the continent. While hornbills tend to live and hunt alone, they do mate for life, maintaining a monogamous relationship year after year. And with a lifespan of 20 years in captivity, it"s entirely possible that there are some yellow-billed hornbill grandparents out there. Why do we mention that? Because we"re celebrating National Grandparents Day in the US today!Desktop Version

For the love of bikes
In honor of World Bicycle Day, we share a bird"s-eye view from Utah of two mountain bikers riding on the Shafer Trail switchbacks of White Rim Road in Canyonlands National Park. In 2018, the UN officially recognized "the uniqueness, longevity and versatility of the Bicycle, which has been in use for two centuries, and that it is a simple, affordable, reliable, clean and environmentally fit sustainable means of transportation."Desktop Version
It s time for spring
It s time for spring
This 40-foot sundial stands atop the Parnidis Dune, one of the scenic highlights of the Curonian Spit, a UNESCO World Heritage Site shared by Lithuania and Russia. Built in 1995, the sundial was damaged by a hurricane a few years later and rebuilt in 2011. It accurately tells time by creating shadows on the steps, with notches for hours and half hours, as well as months, equinoxes, and solstices.Desktop Version

Super sandy Sweet 16
We"re in the Rockies of southern Colorado to celebrate Great Sand Dunes National Park and Preserve"s 16th year as a full-fledged national park—though it was a national monument from 1932, and both the dunes themselves and the surrounding valley"s history are far more ancient.Desktop Version
An island hopper s paradise
An island hopper s paradise
Welcome to sunny and sultry Seychelles, a tropical island nation just south of the equator in the Indian Ocean, roughly 900 miles off the eastern coast of Africa. The gorgeous beach you see here is Anse Source d"Argent on the island of La Digue, one of 115 islands that make up this tropical republic. Anse Source d"Argent has long been a favorite of photographers, who are drawn to its contoured, dark granite boulders, pristine white sand, and turquoise-colored water. Beachcombers and sun worshippers also flock to the Seychelles because of their consistently great weather—daily high temperatures almost always stay within a comfortable range of between 75 and 90 degrees Fahrenheit all year round.Desktop Version
Gazing upon Portraits of Change
Gazing upon Portraits of Change
For the start of Women"s History Month, we"ve come to Union Station in Washington, DC, to view a mosaic of historical photographs of thousands of American women who fought to win voting rights. The ratification of the 19th Amendment, on August 18, 1920, finally secured the legal right of women to vote, but this mainly benefited white women. Despite heroic contributions to achieve suffrage, Black, Indigenous, and other women of color continued to face barriers to voting in the form of poll taxes, restrictive local laws, and hostile intimidation. This mosaic, called "Our Story: Portraits of Change," attempts to show a more complex history of the fight for American women"s right to vote.Desktop Version
A circular celebration
A circular celebration
It"s Pi Day, the day we celebrate the mathematical constant π. This day was chosen because today"s date, March 14, expressed numerically, matches the number"s first digits, 3.14. Pi represents the ratio of a circle"s circumference to its diameter. It can be used to compute the area and circumference of a circle, such as the circles that make up this bridge we"re looking at here in Copenhagen. (Who said math wasn"t useful in the real world?) Many people mark the day with activities based around mathematics—and most also serve pie. We can"t think of a more delicious way to study geometry.Desktop Version

Art in the chapel
You have until Oct 31 to get to Governors Island in New York Harbor to see artist Jacob Hashimoto’s installation ‘The Eclipse.’ The Colorado native built this room-filling artwork out of rice-paper and bamboo kites, stringing the delicate pieces across the ceiling of the Chapel of St. Cornelius. ‘The Eclipse’ is accompanied by another of the artist’s works, ‘Never Comes Tomorrow,’ which is on display in Liggett Hall Archway, also on the island.Desktop Version

Maine"s Acadia National Park serves up spectacular views at most every turn. But the park"s Otter Cliffs on Mount Desert Island offer the adventurous among us a chance to take in the picturesque Atlantic shoreline from the edge of a sheer granite wall. Rising some 60 feet above the crashing waves below, the cliffs are shown here at low tide—when the tide is up, that ledge at the bottom is completely submerged.Desktop Version

Was there a time in your childhood when you told your parents, ‘I want to study dinosaurs when I grow up!’? On National Fossil Day, we encourage you to channel that childhood curiosity. The event, a celebration of paleontology, often includes events at local museums, parks, and schools. Participants may get to see amazing remnants of the past, such as the dinosaur tracks on our homepage, which were photographed near Tuba City, Arizona, in the Navajo Nation.Desktop Version
Up in the Highlands
Up in the Highlands
There"s a good chance the occupants of that car you can see in this photo, winding along a remote highway in the Highlands of Iceland, won"t encounter any other visitors to this desolate region. Accessible only during the summertime, roads across the Icelandic Highlands pass through mostly uninhabited volcanic desert. Frequent volcanic activity in the area creates a porous topsoil full of chemical compounds that aren"t conducive to plant growth. Besides, much of the rainfall is quickly absorbed so plant life only appears alongside glacial rivers. Despite this seemingly unwelcoming environment, adventurous travelers come to the Highlands every summer to see firsthand an ecosystem so unearthly that NASA conducted training missions here for some of its Apollo astronauts.Desktop Version
Mountain mists over Bavaria
Mountain mists over Bavaria
In modern German, the word for this month is "November." But an older German name was "Nebel-mond," which translates as "fog month" in English—it"s the time of the year when fog is most likely to roll in. In some parts of the world the topography and local climate make fog a regular feature of the weather, especially during certain times of the year. That’s called "fog season." San Francisco has a fog season. Tampa, Florida, does too. Is there a fog season where you live?Desktop Version

What are we looking at?
On National Poinsettia Day we"re taking an up-close look at a poinsettia leaf. Although many people assume the red, white, pink, purple, or marbled colors are flowers, they"re actually bracts, a type of leaf that aids in reproduction, usually by turning color as the plant develops true flowers. On the poinsettia, the bracts, surrounding small yellow clustered buds called cyathia, flag down pollinators just as flower petals do.Desktop Version
Looking back at Yellowstone, 30 years after the fires
Looking back at Yellowstone, 30 years after the fires
Nature’s resiliency is on full display here at Yellowstone National Park, where new growth has emerged among the trees charred by the massive 1988 wildfires. More than 1 million acres in the greater Yellowstone area were affected by the blazes that summer, scarring 36 percent of the park. Today marks the 30-year anniversary of Black Saturday, a day when the park saw some of the worst damage, with smoke and ash blackening the skies. But when cool, moist weather brought an end to the devastating fires in late autumn, the ecosystem immediately began to recover. Fire has long been part of the complex ecosystem at Yellowstone and many species have even adapted to rely on fire to open up the canopy, spread seeds, and diversify the habitat.Desktop Version

A night on the (ghost) town
A night on the (ghost) town
The spooky scene here might look like a place you"d want to avoid, but it"s not likely to scare you—not too much anyway. It"s the Fort Rock Valley Historical Homestead Museum in central Oregon, a collection of abandoned homestead-era buildings from the area. In the late 19th and early 20th centuries, people acquired federal lands around here for farms and ranches via the Homestead Acts. But most left within a few years due to the hot, dry summers and extremely cold winters. Today, the buildings are assembled as a ghost town and contain items from that period, including furniture, dishes, and tools. There"s also a nearby cemetery which, according to local lore, is haunted by the ghost of rancher and author Reub Long riding his horse.Desktop Version
Take a hike near Lovers Lane
Take a hike near Lovers Lane
For those of you who love getting outside, you"re in luck! Today is Take a Hike Day, an activity the American Hiking Society says will make you happier as you enjoy the great outdoors. And what better way to take a hike than a walk near Lovers" Lane in San Francisco"s Presidio? The sinuous trail we see in today"s photo is called "Wood Line" and was designed by the environmental artist Andy Goldsworthy. By using felled eucalyptus trees, Goldsworthy intended this land art to eventually biodegrade and fade back into the forest floor. It"s one of four of his works within this national park that once served as a US military outpost.Desktop Version
Two rocks and a heart spot
Two rocks and a heart spot
If you really want to earn someone"s affections, fly them to Corsica, rent a car, and take a drive on the only road that cuts through the red volcanic rocks of Calanques de Piana. Some call the naturally occurring rock formation in today"s Valentine"s Day photo "the two lovers," while others call it "the heart of Corsica." (Spot the heart?) Like most affairs of the heart, the path to this geological valentine is circuitous—it"s a winding road, sometimes too narrow to share with oncoming vehicles (the occasional pullovers help). Our vantage point may be a good spot for you to pull over, especially if it"s sunset, to see the rocks aglow as the sun creeps west toward the horizon.Desktop Version

Goðafoss is one of the hundreds of show-stopping waterfalls Iceland is blessed with. And though it isn"t the island"s highest waterfall—that would be Morsarfoss at over 787 feet—or most powerful (the thundering Dettifoss), Goðafoss, has, within its swirling waters, its own story to tell.Desktop Version
A cutting-edge art gallery opens in Paris
A cutting-edge art gallery opens in Paris
Fine art has found a new canvas here in Paris, where L’Atelier des Lumières opened in April as the city’s first digital art museum. The venue, housed in a 19th-century foundry, uses 140 digital projectors to splash paintings high onto the walls and across the floors, allowing visitors to walk through, over, and into some of the world’s most famous pieces of art. L’Atelier des Lumières opened with an exhibit featuring works by Gustav Klimt, the prominent Austrian painter best known for ‘The Kiss,’ a portrait of a couple locked in an intimate embrace. Klimt was known for incorporating silver and gold leaf into his art nouveau-style oil paintings, creating an ethereal effect.Desktop Version
Finding a balance between wetlands and water treatment
Finding a balance between wetlands and water treatment
Take a stroll through the Wakodahatchee Wetlands and you"ll likely spot great blue herons, like the fluffed-up pair we"re featuring today. Located in Delray Beach, Florida, and created on 50 acres of wastewater utility property, the park first opened to the public back in 1996. A three-quarter-mile boardwalk takes visitors over ponds and through marshes, offering the chance to see more than 150 bird species, plus turtles, fish, frogs, alligators, and other Floridian fauna. Every day, the Palm Beach County Water Utilities Department pumps about 2 million gallons of highly treated wastewater into the wetlands. Then algae and other plants naturally finish the purification process before the water seeps back into the water table. Quite an upgrade from a yucky wastewater pond.Desktop Version
