World Jellyfish Day
World Jellyfish Day
Drifting along our shores and into our calendar, it"s World Jellyfish Day! Jellyfish can be found in all the world"s oceans, in all shapes and sizes. There are about 2,000 species, all lacking hearts, bones, and brains. Pacific sea nettle jellyfish, seen here, have vibrant golden-brown coloring and long tentacles and inhabit the coastal waters of California and Oregon. Moon jellyfish are pale with short tentacles, and, in an appropriate twist, went into orbit aboard the space shuttle Columbia in 1991, to help scientists study their unique biology. Jellyfish play a vital role in the ocean"s food chain, as the main food source for many animals, including sea turtles. Their numbers are impacted by climate change, marine pollution, and overfishing, and in turn have reverberating effects on sea life around them.Desktop Version

Bisti/De-Na-Zin Wilderness, New Mexico
Bisti/De-Na-Zin Wilderness, New Mexico
Time is the great transformer, changing the world and all of us. For instance, this New Mexico badland—the Bisti/De-Na-Zin Wilderness—was once a lush, tropical forest. Nearly 70 million years ago, instead of twisted terrains and towering spires, this place was home to an array of Late Cretaceous dinosaurs, including armored Ankylosaurs, duck-billed Hadrosaurs, and mighty Tyrannosaurs. Today, the area is filled with wonders of a different kind, rock formations that look more like sculptures than natural phenomena. Bisti/De-Na-Zin is named after Navajo words: Bisti means "among the adobe formations," and De-Na-Zin means "standing crane," a reference to nearby rock carvings of the bird. Visitors to the Four Corners region shouldn"t miss out on this otherworldly landscape of shale and sandstone.Desktop Version

Are you ready for winter? These brown bears of Katmai National Park sure are, and their efforts won"t go unrewarded. Each year, park rangers organize a bracketed tournament to crown one ravenous contender as the fattest bear. Webcams are set up so anyone can join the crowds watching these bears chow down on sockeye salmon, as the fish return to the park to spawn. Once you"ve witnessed the feast, you can vote for which bear you think should win the title. New generations will bring new competitors, but they have big paw prints to fill.

Seitan Limania Beach, Crete
Seitan Limania Beach, Crete
Crete is the largest and most populous of all the Greek islands, and also the farthest from the mainland (in fact, it"s just about halfway to Turkey). This big little island is small enough to drive across in a few hours but full of wonders, from mountain ranges to gorges to beautiful beaches. Take this jewel box of turquoise water near the port city of Chania, for example. Set on the easternmost of three peninsulas that stick out like horns from the northwest shoreline of Crete, Seitan Limania is one of the most photographed beaches on the island.Desktop Version
Farmers Day
Farmers Day
Come and gather around, folks! It"s time to express our gratitude toward the harvesting heroes, the guardians of crops: farmers. Farmer"s Day is a celebration of determination and a deep-rooted relationship with the land. From dusk to dawn throughout the seasons, farmers work tirelessly to ensure that produce shelves stay stocked. The interior northwest"s Palouse region is one of the country"s most fertile farming regions, with rolling hills of wheat, legumes, and canola, as seen here today. Old barns with rusty roofs and weathered wood tell tales of harvests and hardships faced by generations of farmers. So, when you eat your next meal, we encourage you to take a moment and think of the workers who produced that food from the land.Desktop Version

He received the Nobel Peace Prize in 1964, but his life was cut short by an assassin in 1968.Desktop Version
Kinder Scout, Peak District National Park, England
Kinder Scout, Peak District National Park, England
Within the vast expanse of England"s Peak District National Park lies Kinder Scout Nature Reserve, the site of an historic people"s protest. At around 2,087 feet, Kinder Scout is the park"s highest point and its rugged moorlands and windswept plateaus have drawn walkers and nature enthusiasts for generations. In 1932, it was the stage for a "mass trespass," in which hundreds of people on foot protested for public access to these lands. At the time, many areas of open countryside were closed to the British public. This act of civil disobedience prompted much public sympathy, which eventually led to the establishment of the UK"s first national parks. The Peak District National Park was the first, designated in April 1951, ensuring that these hills and valleys would be preserved for future generations to enjoy.Desktop Version
World Oceans Day
World Oceans Day
On World Oceans Day, you"re invited to dinner below the sea, hosted by these long-beaked common dolphins. This pod, off the Eastern Cape in South Africa, is employing an ingenious hunting technique, herding a school of frantic sardines toward the surface of the water so they have no escape, essentially driving them against a wall. Once pinned near the surface, the sardines are easy pickings for the hungry dolphins and any other lucky bystanders, like these dive-bombing Cape gannets who are quick to pounce on the opportunity. The technique requires teamwork of course but that comes easy to dolphins, known for their intelligence and tight familial bonds.Desktop Version

Today, it is a popular getaway for nature enthusiasts and travelers seeking adventure.Desktop Version
La Geria wine region, Lanzarote, Canary Islands
La Geria wine region, Lanzarote, Canary Islands
Surrounded by rugged, dark landscapes, La Geria is a marvel of viticulture. Most of the Spanish island of Lanzarote is treeless and covered with black-gray soil. This thick blanket of volcanic gravel is the result of a series of eruptions in the 1700s. By 1775, farmers started growing crops in the new layer of nutrient-rich soil. Volcanic soil absorbs and retains moisture, and the ash keeps its temperature favorable for growing grapes. The holes surrounded by stones you see in our image were dug to protect young grape plants from strong winds. La Geria"s innovative approach to cultivation in an arid climate has been rewarded with its abundance of fine wine, fermented from Malvasia grapes.Desktop Version
Happy Thanksgiving!
Happy Thanksgiving!
While people gather across the country for feasts of turkey, mashed potatoes, and stuffing, you may wonder about the origins of Thanksgiving. Early English settlers had plenty to be thankful for, whether surviving the long voyage to America or the first harsh winters. Written records tell of an early thanksgiving shared between Plymouth Pilgrims and Wampanoag Native Americans, who provided a harvest of corn, deer, and turkey. There were many early days of thanksgiving, but an official, national celebration was proclaimed by George Washington in 1789, and has been a part of our holiday season ever since. Today, we wish you good company and plenty of things to be thankful for. Happy Thanksgiving!Desktop Version
