World Octopus Day
World Octopus Day
What exactly are we looking at here? The veined octopus, also known as the coconut octopus, is one of the smartest animals on Earth, building shelters from seashells and coconut shells. If you peek inside, you may spot those telltale suction cups that cover the creature"s eight limbs. These arms contain clusters of neurons, which make them particularly sensitive, and each arm can be used separately to perform complex tasks. Octopuses can also match the color—sometimes even the texture—of their environment, making them even more difficult to spot. There"s lots more to learn about these fascinating animals, and World Octopus Day is a great day to do it. You could always start with the Academy Award-winning documentary "My Octopus Teacher."Desktop Version
Arches National Park anniversary
Arches National Park anniversary
Red as far as the eye can see and clear blue skies overhead. Welcome to Arches National Park, Utah. The story of this otherworldly landscape starts 65 million years ago when a dry seabed stood here. Over time, geological forces warped and squeezed the land, twisting the sandstone into lumps and bumps. Later, wind and water carved out the arches, pinnacles, fins, and balanced rocks that now stand in this area. The park has more than 2,000 natural stone arches, the highest concentration of these structures anywhere on Earth. In today"s image, we can see two of them: Double Arch, as seen through Cove Arch. The larger arch of Double Arch spans 144 feet and is 112 feet tall, the tallest and second-longest of the park"s arches.Desktop Version
World Penguin Day
World Penguin Day
Why fly when you can slide? Happy World Penguin Day! There are 18 species of these flightless birds, 17 of which live in the Southern Hemisphere. Today"s Antarctic image stars Adélie penguins, discovered in 1840 by French adventurer Jules Dumont d"Urville, who named them after his wife, Adèle. Despite their small size, Adélie penguins are sleek swimmers and can dive as deep as 575 feet in search of shrimp-like krill or fish. They are social animals that gather in small colonies for foraging, hunting, and protection. While it may seem mischievous, Adélies steal pebbles from nearby nests to strengthen their own, safeguarding their eggs and chicks from Antarctica"s harsh conditions and predators.Desktop Version

A breathtaking maze of sandstone formations and awe-inspiring views awaits you at Bryce Canyon National Park in Utah. People have lived in this area for at least 10,000 years, including the Anasazi, Pueblo, and Paiute Peoples.

National Fossil Day
National Fossil Day
For National Fossil Day, we"re looking at the mesmerizing Painted Hills, found in the John Day Fossil Beds National Monument in Oregon. Those stripes of red, tan, orange, and black were formed over tens of millions of years, the different layers in the claystone hills reflecting changes in the climate over that period. The monument itself is divided into three units, Painted Hills, Clarno, and Sheep Rock. In the latter, you"ll find the Thomas Condon Visitor Center with a paleontology lab and a museum displaying hundreds of fossils. In the fossil beds, the remains of more than 100 species of mammals have been found, including saber-toothed tigers, turtles, and opossums, as well as many fossilized plant species. While the landscape might sometimes look otherworldly, it offers us a peek into Earth"s dynamic and fascinating history.Desktop Version

Celebrating Charles Darwin
Celebrating Charles Darwin
Today, we celebrate Darwin Day—a shout-out to Charles Darwin and his game-changing ideas about life on Earth. As an English naturalist, geologist, and biologist, his theory of natural selection revolutionized our understanding of species, evolution, and our role in the natural world. His work, "On the Origin of Species," published in 1859, laid the foundation for modern evolutionary biology. This day marks the birthday of Darwin and honors his genius while promoting curiosity, science, and critical thinking.Desktop Version

Katahdin Woods and Waters National Monument anniversary
Katahdin Woods and Waters National Monument anniversary
Welcome to Katahdin, where dense woodlands and pristine waterways stretch out as far as the eye can see. Covering nearly 87,500 acres, this new national monument was established eight years ago today. Maine"s logging industry was a big part of this region for over a hundred years but declined toward the end of the 19th century. Efforts to preserve its landscape were spearheaded by philanthropist Roxanne Quimby. She started buying land near Baxter State Park in 2001 and donated it to the federal government in 2016, ensuring its preservation for future generations.Desktop Version
White trilliums blooming in Ontario, Canada
White trilliums blooming in Ontario, Canada
Three petals, three leaves, and three stigmas—that"s the white trillium for you, whose name derived from the Latin word for "three." Native to eastern North America, the spring-blooming species is one of the most common woodland wildflowers.

From gracing US postage stamps to being the state wildflower of Ohio and an official symbol of Canada"s Ontario, the white trillium is ingrained in our culture. Beyond its aesthetic appeal, the plant has earned its stripes in the world of herbal medicine. So, next time you find yourself wandering through the woodland realm, keep an eye out for this floral gem!Desktop Version
National Umbrella Day
National Umbrella Day
It"s National Umbrella Day today, a quirky celebration that honors one of the simplest yet most essential inventions in human history: the umbrella, or parasol. Over 4,000 years ago, in ancient Egypt, Assyria, and China, these foldable canopies were first used to shield people from the sun. It wasn"t until the 17th century that the umbrella, as we know it today, gained popularity in Europe, initially as a luxury item primarily for women. Fast-forward a few centuries, and these weather shields have become a staple in pop culture, too. Remember Mary Poppins with her iconic umbrella that helped her fly, or Rihanna"s hit song "Umbrella"?Desktop Version

Not so long ago, humanity took its first step beyond Earth. For thousands of years, we gazed at the stars, dreaming of what lay beyond. Then, on April 12, 1961, one man left the planet and changed history forever. That morning, Soviet pilot Yuri Gagarin climbed into a small, spherical spacecraft named Vostok 1. The countdown began. The engines ignited. As the rocket roared toward the sky, he called out, "Poyekhali!"—"Let"s go!" And just like that, Earth had its first space traveler.Desktop Version

Today, it"s marked by events, protests, and campaigns addressing issues like gender pay gaps, domestic violence, and access to education. From trailblazers like Marie Curie, who illuminated science, to Malala Yousafzai, who champions education, women have proven time and again that they don"t just participate; they innovate.Desktop Version
Veterans Day
Veterans Day
Freedom is not free, and nobody understands that better than veterans. Today, America honors its military men and women for their service. The holiday originally celebrated a temporary halt in fighting between Allied nations and Germany during World War I—the official end of the war came the following year in 1919. Armistice Day, as it was later named, commemorated this respite, and it became a federal holiday in 1938. A few years later, America fought in World War II, and later, the Korean War. As a result, Congress amended the holiday in 1954, exchanging the word "Armistice" with "Veterans" to include veterans of all the country"s wars.Desktop Version
Caribbean flamingos, Yucatán Peninsula, Mexico
Caribbean flamingos, Yucatán Peninsula, Mexico
Ever seen a group of flamingos take to the skies? If you have, there"s a good chance they were Caribbean flamingos, also known as American flamingos, as seen in Yucatán Peninsula, Mexico, in today"s image. Flamingos are referred to as a flamboyance when in a group, but they can also be called a stand, colony, or pat. The Caribbean flamingo is the largest flamingo species in the Americas and the only one native to North America. These vibrant birds are typically found around brackish and saltwater areas, like marshes, estuaries, and along coastlines. Because of their pink color, they"re often confused with roseate spoonbills. However, their long necks and bent bills distinguish them from other wading birds like the great blue heron and wood stork.Desktop Version

Collared aracari in Costa Rica
Collared aracari in Costa Rica
Black and yellow plumage, bright eyes, and an oversized bill—meet the collared aracari, a fascinating tropical bird. Gracing the forests from Mexico through Costa Rica, where today"s image was taken, to Colombia and Venezuela, this toucan gets its name from the red marking on the back of the neck. These birds circle through the air in groups of up to 15, and at night, snuggle together in tree cavities. Their song is as unique as their look—a high squeaky note that sounds like "seek," sometimes a "purr" or even a raspy "grhhrr." Although deforestation and hunting pose threats to these birds, they are not endangered. For now, collared aracaris remain a captivating sight, a splash of color, and a burst of life amid the sprawling branches.Desktop Version
US Election Day
US Election Day
It"s time to get out and vote! In 1845, Congress designated the first Tuesday after the first Monday in November as the day Americans vote for most federal offices. Prior to this, states held elections on a date of their choosing within about a month of early December, which created issues with early and late elections. For convenience and to save money, many elections for state and local offices are also held on Election Day.Desktop Version
