Uncommon clouds are gathering
Uncommon clouds are gathering
A satellite view of the Mania River in Madagascar allows us to see a curious cloud pattern. It"s common for cool, moist marine air to rise and form dense clouds over bodies of water, then for the clouds to evaporate as they drift over warmer, drier land. The opposite is happening here: Puffs of clouds are forming over land, but not over water. That"s because Madagascar"s tropical rainforests are warm and wet enough that evaporating moisture rises as the day heats up. When it rises high enough, the moisture encounters cooler air, which condenses the water into clouds. Generally speaking, clouds will form where the air is rising, which in this case is only over the land. Above the river, the air is cooler and descending, so no clouds are forming there.Desktop Version
Beware the Ides of March
Beware the Ides of March
We"re at the Roman Forum for the Ides of March, a date made famous as the time of Julius Caesar"s assassination. According to the ancient historian Plutarch, Caesar had been warned by a seer that his life would be in danger no later than the Ides of March, something that William Shakespeare dramatizes in his famous tragedy of Caesar’s life and assassination. While historical fact and fiction can diverge, we do know that before March 15, 44 BCE was over, a group of senators had intercepted Caesar here in the Forum as Caesar was on his way to the Senate House. They stabbed him 23 times, killing him. Afterward, Rome descended into civil war, ending the Roman Republic, and leading to the rise of the Roman Empire.Desktop Version
Everyone s watching the Perseids
Everyone s watching the Perseids
These dinosaurs are (nervously?) looking at the annual Perseid meteor shower, photographed at the Dinosaur Museum of Erenhot in the Inner Mongolia Autonomous Region of China. Known as Dinosaur City, Erenhot gained attention in the 1920s when dino fossils were found there. It"s believed that more than 20 kinds of dinosaurs lived in the area during the Cretaceous Period around 70 million years ago.Desktop Version
Tom Turkey takes Manhattan
Tom Turkey takes Manhattan
The Tom Turkey float has been in the Macy’s Thanksgiving Day Parade since 1971, missing only one outing in 2003. The hat-wearing turkey flaps his wings and rolls out as the lead attraction in the parade, with Santa Claus bringing up the rear to bookend this holiday tradition. Long before Tom joined the lineup, and a few years before giant balloons shaped like animals and cartoon characters came along, live animals from the Central Park Zoo were a big feature in the parade. Did you watch the procession today?Desktop Version
Celebrating 200 years of statehood
Celebrating 200 years of statehood
We"re wandering out onto the striated coastal rocks of Maine"s Pemaquid Point at sunrise to mark 200 years since Maine joined the Union as the 23rd US state. With roughly 5,000 miles of jagged, rocky coastline, Maine is studded with dozens of lighthouses, and the light at Pemaquid Point is one of the most celebrated—and historic. First, that history: President John Quincy Adams commissioned the lighthouse in 1827, but it needed to be rebuilt in 1835 after the original began falling apart. (Note: Don"t use salt water when mixing your mortar.) Maine residents chose the Pemaquid Point Light for display on their state"s coin as part of the US 50 State Quarters Program.Desktop Version
In the footsteps of Leopold Bloom
In the footsteps of Leopold Bloom
Today we"re looking down at St. Stephen"s Green in Dublin in honor of Bloomsday, a day when people celebrate Irish author James Joyce and his famous 1922 novel "Ulysses." But why today, you ask? That"s because the novel follows the meanderings and thoughts (and meandering thoughts) of the protagonist, Leopold Bloom, and a host of other characters—real and fictional—from 8 AM on June 16, 1904, through the early hours of the next morning.Desktop Version
The Christmas Bird Count begins
The Christmas Bird Count begins
Today marks the start of the annual Christmas Bird Count, a bird census sponsored by the National Audubon Society that also happens to be the longest-running citizen scientist survey in the world. Each year the count runs from December 14 to January 5, giving bird lovers across North America a chance to join in, get outside, and spot some birds. The findings recorded by participants are collected and used to gauge the health of various bird populations. This information is then used to focus conservation efforts on particular species and geographical areas.Desktop Version
Is there a bug-egg emoji for this?
Is there a bug-egg emoji for this?
Nothing says ‘smile!’ like a bunch of eggs laid by a member of the Pentatomidae family of insects. Not all stink bug eggs look like they have faces, but this incident of ‘life imitates emoji’ was too good to pass up today. That’s right, it’s World Emoji Day. Those tiny, cartoonish pictures that often stand in for words and phrases in social media posts and text messages have become a system of communication all their own. But why on July 17? Early on in the (very recent) history of emoji, the calendar emoji displayed July 17. So, when the time came for emoji to get their own day of recognition, this date stood out above all others.Desktop Version
Mapping courage in the Seventh Ward
Mapping courage in the Seventh Ward
To mark the beginning of Black History Month, we"re visiting a highlight of Philadelphia"s famous Mural Mile. The larger-than-life figure depicted on the left in this mural is W.E.B. Du Bois, trailblazing scholar, sociologist, author, and co-founder of the National Association for the Advancement of Colored People. It was here, in Philadelphia"s Seventh Ward neighborhood during the late 1890s, that Du Bois conducted a detailed study of an African American community. He used methodologies—including detailed data visualizations—that were decades ahead of his time, mapping out every household and documenting the challenges that residents encountered as they tried to achieve success and happiness in the decades after Reconstruction and the dawn of the Jim Crow era.Desktop Version
Who doesn’t love a ‘Puppy’?
Who doesn’t love a ‘Puppy’?
The Guggenheim Foundation has opened three major museums around the world—in New York City; in Venice, Italy; and here in Bilbao, Spain. A fourth museum is currently being developed in Abu Dhabi, in the United Arab Emirates. The Guggenheim Museum Bilbao is home to a modern art collection and large, site-specific pieces, such as ‘Puppy’ by Jeff Koons, seen here. Koons combined the plants and planting style of 18th-century European gardens with a very 20th-century pop-art aesthetic when he created the giant dog sculpture. Where are we off to next?Desktop Version
World Space Week begins
World Space Week begins
For the start of World Space Week, today"s homepage features a composite of images taken by NASA"s Juno probe as it swooped past Jupiter. The largest planet in our solar system, Jupiter also has the largest number of moons: 79. Jupiter is the Roman counterpart to Zeus, and the planet"s major moons are named after Zeus", shall we say, extra-marital partners. So, when it came time to name NASA"s most ambitious Jupiter probe, they decided to name it after Jupiter’s wife, Juno, so that she could keep an eye on him. Every 53 days in the course of its wide and complex orbit, the Juno probe makes its closest approach, snapping shots like these as it speeds past the gas giant in just two hours. World Space Week starts on the anniversary of the launch of the very first space probe, Sputnik, which entered orbit around the Earth on October 4, 1957.Desktop Version
Mesmerizing murmuration
Mesmerizing murmuration
Around this time of year, as temperatures dip in the Northern Hemisphere, European or common starlings put on a dazzling show. Most of the time, these noisy birds are scorned for their bullying behavior at the bird feeder. But in autumn months, they gather to roost in huge flocks, as they’re doing here in Blackpool, England. At dusk, the starlings take flight en masse and flock together in a hypnotizing, swirling cloud of fluttering wings. These flocks are called mumurations. They"re thought to help keep the birds warm while also acting as a defensive tactic to confuse predators like hawks and falcons. But maybe the raptors are rendered harmless simply because they’re awestruck by the starlings" synchronized spectacle.Desktop Version
The migrating monarchs of Michoacán
The migrating monarchs of Michoacán
Probably the most recognizable of all the butterfly species, monarchs are helpful pollinators that can be found across the United States and Canada in the summer. But each fall, millions of these orange and black beauties embark upon one of the world"s most amazing migrations. The insects make use of air currents to make the long journey south to the mountains of southwestern Mexico, a flight of up to 3,000 miles. Aside from being a staggeringly great distance for these delicate insects to fly, it"s also a journey to a place that not one of them has ever been to before. And unlike the many bird species that undertake annual round-trip migrations, these butterflies will never return to the north. Why not? Because the distance and length of the total annual migration cycle is greater than the lifespan of individual monarchs.Desktop Version
A river runs through rice fields
A river runs through rice fields
We"re peering down the winding Ngo Dong River at a group of rowboats meandering through rice paddy fields. This is Ninh Bình province in Vietnam, about 60 miles south of Hanoi. On these two-hour tours by traditional Vietnamese rowboat, visitors wend their way between limestone karst peaks, through grottoes, and, if they"re lucky, by workers harvesting rice in the fields, their wide-brimmed hats shielding them from the sun. Perhaps the most spectacular time to take this river cruise is around harvest time in late May and early June when the paddy fields are awash in a golden glow with a backdrop of bright green hillsides. But don"t be surprised if the person rowing your boat moves the oars from hands to feet. It"s tradition here for rowers to give their arms a break and let their legs take over.Desktop Version
It s Coffee Day
It s Coffee Day
These coffee cherries are from Colombia"s "Coffee Triangle," where coffee trees flourish among some of the tallest palm trees you may ever see. The cherries take several months to mature. As they ripen, they change color from bright green to dark red. The dark red cherries are perfect for picking. Once the cherries are picked, the fruit surrounding the seeds (or "beans") is removed, then the beans are cleaned and eventually roasted. Colombian coffee is regarded as some of the best in the world.Desktop Version
Whatever floats your boat
Whatever floats your boat
These turquoise waters are lapping the sands of Mont Choisy Beach in Mauritius, an island nation off the southeastern coast of Africa. It"s a popular spot for locals and tourists to swim, enjoy the sun, or head out in one of these boats to catch some fish. The island has a unique cultural history. Most scholars believe it was known to Arab seafarers by the 10th century, but it remained uninhabited until Portuguese sailors established a base on the island in the early 1500s. Mauritius was later colonized in succession by the Netherlands, France, and Great Britain before gaining independence in 1968. Over the years, Mauritius has evolved from a low-income economy based mostly on sugarcane (still one of its biggest exports), to a more diverse one that includes tourism, clothing production, and technology.Desktop Version
A festival of lights in India
A festival of lights in India
In observance of the Hindu holiday called Diwali, people gathered on the banks of the Sarayu River in the northern Indian town of Ayodhya in autumn of 2018 to light candles and oil lamps called "diyas." Attendees that night set a Guinness World Record by keeping 300,000 diyas lit for five minutes. The lights are symbolic of the triumph of good over evil, light over darkness—central themes of Diwali. Ayodhya is a significant location in the Hindu faith, long thought to be the birthplace of Rama, an incarnation of Vishnu, who represents virtue. And as Diwali, a four- or five-day celebration reaches its peak today (the third day), the Hindus of Ayodhya will be back to light up the riverbank. Will they set another record?Desktop Version

When residents of the bustling metropolis of Beijing, China, need a break from their daily grind, many will head about 45 miles north of the city to take in the sights at the Shilinxia Scenic Area. Meaning "Gorge of Stone Forest," Shilinxia is a protected 7.5-mile gorge characterized by waterfalls, green forests, and steep slopes. Since 2016, it"s also featured an amazing main attraction—one of the world"s largest glass sightseeing platforms.Desktop Version
Gamboa Crater, Mars
Gamboa Crater, Mars
It would be pretty tough to live on Mars. It"s cold, dry, and the conditions are harsh. The planet"s average temperature is about –81 degrees Fahrenheit, but it can get as low as –243 at the poles. But with many canyons, extinct volcanoes, and ice caps, it"s beautiful to look at from afar. Most photos of the red planet highlight its rusty color, caused by high levels of iron oxide.Desktop Version
Art and soul
Art and soul
Art can seem like a portal to another dimension, as Irish-born artist Laura Buckley shows us in today"s mind-bending image. She posed here (and there, and there, and there…) with her mixed-media sculpture "Fata Morgana" at London"s Saatchi Gallery last year. The work is outwardly unassuming, made from a hexagonal wood-frame tube lined on the inside with reflective acrylic and capped on one end with a projection screen. When a viewer enters the installation, the mirrored surfaces reflect their image along with a video projected on the screen, merging the two into a whimsical mirage.Desktop Version
Dancing waters of Dubai
Dancing waters of Dubai
With the 2009 opening of the Dubai Fountain, featured in today"s image, the city of Dubai claimed another record for the books—"world"s tallest performing fountain.’ It"s located appropriately enough at the foot of the Burj Khalifa, currently the world"s tallest building. Designed by the same company that created the fountains at the Bellagio Hotel in Las Vegas, everything about the Dubai Fountain is impressive. Over 900 feet long and located in the 30-acre Burj Lake, the fountain has more than 6,600 lights and 75 color projectors. These are used to create over 1,000 different "water expressions" and provide a rainbow of colors, all perfectly choreographed to a carefully crafted musical playlist.Desktop Version
Jackie Robinson Day
Jackie Robinson Day
On April 15, 1947, more than 26,000 spectators at Brooklyn"s Ebbets Field witnessed history as Jackie Robinson became the first Black player on a modern-era major league baseball team. (Three Black players played in the major leagues briefly in the 19th century before the color line was fully established.) Robinson endured racist resistance throughout his first season with the Brooklyn Dodgers, but the national pastime"s color barrier was broken, and other players followed him within months. In 1997, Major League Baseball retired Robinson"s number, 42, across all teams, and in 2004 it began the annual April 15 observance of Jackie Robinson Day. This photo shows Robinson signing autographs for fans at spring training in the Dominican Republic the year after his debut.Desktop Version

On this shore, history was made
As the sun sets on a beach in Normandy, France, what appear to be working barges and boats offshore are actually the remnants of a Mulberry harbour, one of the temporary portable harbors created by the Allies during World War II. Their story began 77 years ago today, on D-Day, when the first of the Allied troops touched down on the Nazi-occupied beaches at Normandy. After the Allies successfully held the beachheads, the Mulberries were towed into place so the artificial harbors could provide the port facilities necessary to offload the thousands of men and vehicles, and tons of supplies necessary to sustain the effort to drive the Germans out of France.Desktop Version
