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

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

Earth Day
Today is Earth Day—a day dedicated to celebrating the planet we call home and raising awareness of environmental problems. The seeds of this day were planted back in 1969 when Senator Gaylord Nelson of Wisconsin witnessed events like the Cuyahoga River catching fire and the Santa Barbara oil spill and decided that the world needed an environmental initiative. A year later, the first Earth Day event was held. Now, it has grown into an annual event with more than a billion people in over 193 countries taking part.Desktop Version

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.

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. Unlike some impulsive blossoms that burst into color at the slightest hint of warmth, this plant is a slow bloomer. 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

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
Arbor Day
Arbor Day

On the last Friday of April, people across the country mark the occasion by planting trees, often dedicating them to a loved one. It"s also a great day to celebrate trees themselves. As well as providing homes for countless species of animals, trees absorb carbon dioxide and clean the air we breathe. They also help to keep cities cooler and can even play a role in preventing floods.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

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.
