Today, June 13th, is 'Hayabusa Day.' "Hayabusa" is an asteroid probe launched in 2003 by the Japan Aerospace Exploration Agency (JAXA). Overcoming various troubles such as communication failures, it attracted significant attention by returning to Earth on June 13, 2010. "Hayabusa Day" is a commemorative day established in 2012 to honor Hayabusa and those involved in its projects. In 2014, the successor Hayabusa 2 was launched, and in 2019, it successfully landed a touchdown on the asteroid Ryugu. Today's image shows a capsule containing samples from Hayabusa 2 separated toward Earth and falling on December 6, 2020. The main unit is still operational and continues its expansion mission.

In the Amazon, Valentine's Day has no flowers, chocolates, candlelight or romantic playlists. Even so, these milky frogs of the Amazon pause their routine for an instant of complicity in the heights.

Also known as the milk tree frog, it lives in the canopies, away from the ground, using fingers as suction cups to firm itself on leaves and branches. The bluish skin helps in camouflage in its favorite shift — the night shift — in addition to producing the whitish and toxic secretion that drives away curious people and gives the species its name. When the season comes, the couple attaches themselves to each other and lays dozens of eggs in small reserves of rainwater accumulated in hollow logs.

Romance or survival strategy? In nature, one thing does not exclude the other. In any species, those who walk together go further. On Valentine's Day, these frogs of up to 9 centimeters do not offer the inspiration of grand gestures, but that of discreet presences that make the path lighter.

Tucked away beneath steep cliffs near Cabo da Roca, the westernmost point of mainland Europe, Praia da Ursa feels like the edge of the continent. Reached by a narrow, rugged trail, this secluded beach along Portugal's Atlantic coast is shaped largely by wind, stone and powerful waves. When the tide recedes, the shoreline briefly widens. Smooth rocks emerge, and with them, small signs of life. Limpets cling tightly to the exposed stone, holding fast where the ocean usually breaks.

These modest marine snails are well adapted to conditions here, using strong suction and low shells to withstand surf, shifting temperatures and long periods exposed to air. During high tide or when submerged, they graze on algae, then return to familiar spots as the sea recedes. Praia da Ursa's isolation makes these moments easy to miss and rewarding to notice. In a landscape defined by scale and force, even the smallest survivors reflect the Atlantic coast's quiet resilience.

From above, the lake's smooth surface contrasts sharply with the rugged ground surrounding it. Hnausapollur crater lake—also known as Bláhylur—lies in the heart of Fjallabak Nature Reserve, a remote area of Iceland's highlands shaped more by volcanic activity than by human settlement. The crater formed when magma met groundwater, triggering an explosion that carved out the circular basin visible today.

Over time, rain, meltwater and groundwater accumulated within the basin, forming the striking lake seen in today's image. Its colour shifts with light and weather, often glowing turquoise under clear skies and appearing deeper blue or grey when clouds pass overhead. The surrounding slopes reveal distinct layers of volcanic material, recording successive eruptions that once spread across the landscape.

Fjallabak remains largely undeveloped, protected for its geology and vast open spaces. From this aerial perspective, it's easy to see how powerful natural forces shaped Hnausapollur and why Iceland's highlands continue to captivate visitors—a place where the Earth's restless energy remains visible at the surface

Nocturnal? Only when it is convenient. The burrowing owl in the image decided to ignore the classic script. While other owls go out at night, she takes over the day shift. While others live in trees, it prefers burrows in the ground, excavated or repurposed from armadillos, which function as shelter and observation post.

Small, about 20 to 25 centimeters, it occupies open fields, sandbanks, pastures and even urban areas of Brazil. Its menu includes insects, small rodents, reptiles and even scorpions, helping to maintain local balance. It is territorial and does not act alone. Couples maintain a coordinated vigilance: while one keeps nest, eggs and chicks safe, the other hunts. When threatened, it lets out a sound similar to a snake rattle — an efficient bluff to ward off unsuspecting onlookers.

The buraqueira does not need shadows, nor height, to dominate the space. It makes the ground a viewpoint and the gaze, its first line of defense.

Palermo, the capital of the island of Sicily in southern Italy, is a city where layers of history, art and culture meet in a vivid and sometimes chaotic harmony. Founded by the Phoenicians and later shaped by Romans, Arabs, Normans and Spaniards, it carries traces of many civilisations that passed through the Mediterranean. This rich past is visible in its architecture, from the Arab-Norman palaces and churches recognised by UNESCO to the Baroque facades that define its historic streets.

Art and tradition blend naturally into everyday life, especially in its bustling markets like Ballarò and Vucciria, where colours, voices and scents create an unforgettable atmosphere. Palermo is also a city of flavours, known for its street food culture. From arancine and panelle to sweet cannoli, its cuisine reflects centuries of cultural exchange. Between the sea and the mountains, Palermo offers a unique rhythm, where history is not confined to museums but lives in the streets, in the food and in the people themselves.
