European river otter, Netherlands
The European river otter is more than just an adorable face in the wild. Found across Europe, Asia, and parts of northern Africa, these otters thrive in clean rivers, lakes, and wetlands, serving as an important indicator of environmental health. They are built for agility, with streamlined bodies, webbed feet, and dense fur that keeps them warm even in icy waters. A single square inch of their fur can hold more than 400,000 hairs, making it one of nature"s most effective insulators. River otters were once endangered due to pollution and habitat loss. Thanks to conservation efforts, their populations are rebounding in many regions across Europe.Desktop Version

Picture yourself at the highest peak in the Alps, where the air is crisp and the views are breathtaking. The towering presence of Mont Blanc has left an indelible mark on literature, most notably on Mary Shelley"s "Frankenstein." The last Friday of October is Frankenstein Friday, honoring Shelley"s literary genius and the fascinating creature born from her imagination. "Frankenstein" was conceived during a ghost story challenge.

Forced inside by incessant rain, she penned the tale of Victor Frankenstein and the Creature. A pivotal scene in the novel takes place on a glacier near Mont Blanc, where Victor is confronted by his monstrous creation. This setting, with its surreal beauty and treacherous terrain, perfectly captures a sense of awe and terror.Desktop Version
International Day for Biological Diversity
International Day for Biological Diversity
Life on Earth, from tiny bacteria to towering trees, is interconnected. International Day for Biological Diversity is about celebrating this web of life that keeps our planet thriving. Biodiversity ties into everything, from sustainable farming and clean water to climate action and disaster preparedness. A decline in biodiversity can increase the spread of zoonotic diseases—those transmitted from animals to humans. In contrast, protecting biodiversity strengthens our ability to prevent and respond to health crises like pandemics. Recognizing its crucial role for current and future generations, the United Nations observes this day each year to raise awareness and foster action for conserving the planet"s biological treasures.Desktop Version

This fiery tumbleweed is kochia, which transforms landscapes when it takes on hues of red, orange, and pink in the fall. In the spring and summer, this annual herb resembles a fluffy green ball. Native to parts of Europe and Asia, kochia, also known as "summer cypress," is now widespread throughout the world.

These ornamental plants create a surreal landscape for visitors to wander through and also hold significance in Japanese culture. Historically, they have been dried to create brooms.

Medieval towers in Mestia, Upper Svaneti, Georgia
Medieval towers in Mestia, Upper Svaneti, Georgia
Winter turns Mestia"s medieval towers into icy fortresses. Perched 4,921 feet up in the Caucasus Mountains, Mestia is a charming highland town in northwest Georgia. The town is home to the Svans, a cultural and linguistic subgroup of Georgians. Despite its modest size, Mestia has been an essential hub of Georgian culture for centuries, dotted with the Svan defensive towers, seen in today"s image. Most of these towers were constructed between the 9th and 12th centuries, a period often referred to as Georgia"s Golden Age. However, their roots are believed to stretch even further back, possibly into prehistoric times. Built for both protection and shelter, these towers were not just fortresses but also integral parts of family homes, reflecting the region"s history of resilience and self-sufficiency. Therefore, it isn"t just a town; it"s a living museum where history rises from these towers and echoes through the mountains.Desktop Version

Glacial rivers in Iceland
Glacial rivers in Iceland
Iceland"s glacial rivers have shaped the landscape here in the land of fire and ice over thousands of years. The rivers seen in today"s image are formed from the meltwater of vast glaciers like Vatnajökull, Langjökull, and Hofsjökull. Vatnajökull, the largest ice cap in Iceland, covers over 3,000 square miles—approximately 10% of the country"s landmass. As the glaciers melt, the water carries fine sediments, creating a braided river system with a milky appearance that contrasts with the earthy tones of the volcanic terrain. Every spring and summer, the rivers swell with seasonal meltwater, continually shaping and reshaping the land. Aerial views reveal their intricate patterns, interwoven across the terrain toward the North Atlantic Ocean. The water also powers hydroelectric power stations, reinforcing Iceland"s status as a leader in sustainable energy.Desktop Version
