International Day of Human Space Flight
International Day of Human Space Flight
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

Superbloom in Carrizo Plain National Monument, California
Superbloom in Carrizo Plain National Monument, California
It"s not every day you see a desert burst into colors, but during a superbloom, arid land is covered with endless stretches of flowers.

Superblooms in California typically occur once a decade, but prolonged droughts in the 21st century have made them increasingly less frequent. Drawing attention to California"s diverse flora and rural federal lands, this event offers a temporary boost to local economies.Desktop Version

Participants will parade along the Seine on a flotilla of boats, passing under the Pont Neuf, pictured here, and cheered by spectators lining both banks. Paris is no stranger to historic firsts; the 1900 Games included women competing for the first time, although they made up only 22 of 997 athletes.Desktop Version
Indigenous Peoples Day

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

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
Lei Day
Lei Day
As the first day of May dawns in Hawaii, Lei Day bursts forth in a riot of color, fragrance, and festivity.

They represent love, respect, and the ever-present aloha spirit, described as "the coordination of mind and heart within each person." Lei Day is an all-day fiesta that includes parades, pageants, lei-making contests, hula dances, and feasts.

Sandstone formations in the badlands near Caineville, Utah
Sandstone formations in the badlands near Caineville, Utah
Wavy sandstone ridges stretch across the Caineville Badlands, Utah, resembling nature"s brushstrokes on stone. These formations are made of fine-grained sediment that settled in ancient river deltas and inland seas and later hardened into stone. Over time, erosion carved through the layers, exposing flowing, ripple-like patterns. The sedimentary layers tell a story of shifting climates and ancient landscapes. The barren land, seen in today"s image, may appear lifeless, but during early spring, rainfall blankets the terrain with tiny purple and yellow flowers. Light and shadow shift throughout the day, offering photographers and visitors various angles. While much of the terrain remains rugged, some areas offer easy access, allowing visitors to explore without strenuous hiking.Desktop Version

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
National Find a Rainbow Day
National Find a Rainbow Day
Have you ever spotted a rainbow and felt a little lucky? National Find a Rainbow Day, celebrated today, is all about looking to the sky for that magical mix of sun and rain. Nature"s color wheel has long been linked to myths and legends, from Norse gods to the Irish leprechaun"s pot of gold. But beyond folklore, the science behind rainbows is just as compelling. The first real explanation came from Theodoric of Freiberg, a German physicist, in 1304. He discovered that rainbows form when sunlight enters a raindrop, bends, reflects inside, and then bends again as it exits. This process splits light into its colors, creating the spectrum we see. The classic "ROYGBIV" (red, orange, yellow, green, blue, indigo, and violet) doesn"t tell the whole story—rainbows contain millions of colors blended together.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

Earth Day
Today is Earth Day—a day dedicated to celebrating the planet we call home and raising awareness of environmental problems.
