Two polar bear cubs pick their way across the snow in Svalbard, a remote Norwegian archipelago of glaciers, mountains and frozen fjords deep in the Arctic Ocean. This wild landscape is part of the Barents Sea region, home to one of the world's largest polar bear populations, with around 2,600 bears.

For these youngsters, every outing is an adventure. They explore a world shaped by drifting sea ice, towering ice fronts and months of darkness followed by endless summer daylight. Playful wrestling matches and mock chases may look like games, but they help prepare the cubs for life in one of Earth's most challenging environments.

Svalbard is one of the best places in the world to see polar bears, yet it is also among the fastest-warming regions on the planet. As sea ice conditions change, local bears have shown a remarkable ability to adapt, but their future remains closely tied to the frozen landscapes that define the High Arctic.

Today marks the first day of Hispanic Heritage Month, a nationwide celebration honoring the histories, cultures, and contributions of Americans with roots in Spain, Mexico, the Caribbean, and Central and South America. Observed each year from September 15 to October 15, the month begins on a date that coincides with the independence anniversaries of several Latin American nations, including Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua.

The image shows Fort Union National Monument in northeastern New Mexico, a place where many stories of the American Southwest intersect. Once a major outpost on the Santa Fe Trail, Fort Union stood along a route that carried not only goods and travelers, but also ideas, languages, and traditions between cultures.

As Hispanic Heritage Month begins, sites like Fort Union remind us that the nation's story has been shaped by centuries of cultural exchange. From food and music to language, art, and community traditions, Hispanic influences continue to enrich everyday life across the United States.

In September, the French Riviera is bathed in a softer light, and the Mediterranean landscape takes on fresher tones after the peak of summer. The hills are scented with Aleppo pine, rosemary and wild thyme. In the hinterland, centuries-old olive trees and hilltop villages tell a story shaped by Greek, Roman and Provençal influences.

Along the coastal trails, holm oaks and strawberry trees withstand the summer drought, while fig trees still offer an abundance of ripe fruit. In the bays of coastal towns such as Villefranche-sur-Mer, sailboats and yachts glide gracefully between sea and sky, while the red rocks of the Esterel Massif contrast strikingly with the deep green hues of the Mediterranean scrubland.

Around a secluded cove, the gentle song of the cicadas gradually gives way to a more peaceful atmosphere. The French Riviera offers far more than a postcard-perfect setting: it is a harmonious blend of nature, heritage and the art of living, where the Mediterranean reigns supreme.

In today's image, kochia plants spread across the landscape in China in shades of green and deep red. Native to parts of Eurasia, kochia was introduced to the United States in the late 1800s as an ornamental plant and a source of material for broom making. Its ability to withstand drought, heat, saline soils and low rainfall helped it spread across the Great Plains and much of the American West.

Growing quickly from seed, a single plant can reach more than one metre tall in one season and produce thousands of seeds. Young plants have been used as forage for livestock, particularly in dry regions where other vegetation is scarce. While admired for its striking colours and resilience, kochia is also known to farmers as a hardy weed that can be difficult to control. From American prairies to the vibrant fields seen here in China, it remains a remarkable example of nature's adaptability.

Today, September 14th, is Cosmos Day. Cosmos has various flower meanings, such as 'affection,' 'grace,' 'humility,' and 'harmony,' and on this day, exactly six months after White Day, it is considered a day to give cosmos flowers to lovers and family to express gratitude and affection. Cosmos, also written as 'cosmos,' is cherished as a representative flower of autumn. Although there are several varieties with early and late blooms, the best viewing period is generally from September to mid-October.

The image captures the jagged skyline of Cadini di Misurina at sunrise in Veneto, northeastern Italy. Visitors heading toward nearby Tre Cime di Lavaredo often come for the famous route only to find their attention hijacked by the Cadini. Part of the Dolomites, these needle-like peaks reaching more than 2,800 metres at their highest point seem sculpted for drama. The twist? They started out as ancient coral reefs.

Around 250 million years ago, this region lay beneath a warm tropical sea. As the African and Eurasian tectonic plates collided, the seabed was thrust thousands of metres into the sky, preserving shells and other marine fossils in cliffs now explored by hikers instead of fish.

At sunrise and sunset, the Dolomites glow pink and orange in the Alpine phenomenon known as 'enrosadira,' making these former reefs appear almost lit from within. Today, this UNESCO World Heritage Site preserves one of geology's most improbable stories. From coral reef to mountain skyline, few places have travelled farther.
