Fibonacci Day
Fibonacci Day
On Fibonacci Day, mathematicians and scientists honour one of their own: Leonardo Bonacci. More commonly known as Fibonacci, the medieval mathematician is notable for popularising the Hindu-Arabic numeral system, with its use of zero, decimal points and 10 numbers instead of the ponderous Roman numeral system. He"s most famous, however, for his sequence of numbers: 0, 1, 1, 2, 3, 5, 8... By adding the first two numbers, you arrive at the third, and adding the previous two numbers, you arrive at the next number and so on. Disregarding the zero, the first four numbers correspond to today"s date, 11/23.Desktop Version

Red lechwe, Okavango Delta, Botswana
With their elegant leaps and graceful movements, lechwe are the epitome of agility and poise on the African savanna. These antelopes, known for their distinctive reddish-brown coats and lyre-shaped horns, are native to the wetlands and floodplains of south-central Africa, including the Okavango Delta in Botswana, which is a UNESCO World Heritage Site. Lechwe are social animals, often found in herds of thousands. In the heart of the delta, they are an integral part of the region"s rich biodiversity, coexisting with other species like elephants, lions, rhinos and hippos, wading through the water. Their presence adds to the delta"s natural allure, which draws in thousands of safari enthusiasts and is proof of wildlife"s resilience in the face of environmental challenges.Desktop Version
Tree frog, Costa Rica
Tree frog, Costa Rica
Today"s image features a tree frog. Frogs don"t always get the attention they deserve. These little jumpers have been around since dinosaurs roamed the Earth, and they"ve evolved into some of the weirdest, coolest creatures out there. With over 4,000 known species worldwide, they come in all shapes and sizes, from the tiny New Guinea Amau frog—smaller than a dime—to the large Goliath frog, which can weigh more than 2 kilograms. Some, like the glass frog, are nearly transparent, while others are extremely poisonous. The golden poison frog, for example, carries enough toxin to take down ten humans. And if you think all frogs are swamp-dwellers, meet the desert rain frog, a round little amphibian that survives in dry conditions by absorbing moisture through its skin. Frogs play a crucial role in ecosystems by controlling insect populations and serving as prey for many predators. However, habitat loss, pollution and disease threaten many species.Desktop Version

Poinsettia
Poinsettia
Here"s the red poinsettia, one of the plants from the spurge family, Euphorbiaceae. With its striking star-shaped leaves, the poinsettia has become a symbol of Christmas cheer, brightening homes and public spaces during winter. The history of the poinsettia can be traced back to ancient civilisations. The Aztecs, who called it cuetlaxóchitl, used it to make a reddish-purple dye and to treat fevers. But the plant"s association with Christmas has roots in Mexican tradition, where it"s known as "la flor de Nochebuena" or "Holy Night flower." According to legend, a young girl, unable to afford a gift for Baby Jesus, was inspired to offer humble weeds, which miraculously transformed into the vibrant poinsettias we know today.Desktop Version
Collared aracari
Collared aracari
Black and yellow plumage, bright eyes and an oversized bill—meet the collared aracari, a fascinating tropical bird. Gracing the forests from Mexico through Costa Rica, where today’s image was taken, to Colombia and Venezuela, this member of the toucan family gets its name from the red collar on the back of the neck. Measuring 38 to 40 centimetres long and tipping the scales at a mere 175 to 249 grams, this bird is a wonder of nature"s design. Both male and female aracaris share the same dazzling appearance. These birds circle through the air in groups of 6 to 15, and at night, they snuggle together in tree cavities. Their song is as unique as their look—a sharp "seek" or a whimsical "pink," sometimes a purring sound or even a raspy "grhhrr." Although deforestation and hunting pose threats to these birds, they are currently classified as a least-concern species. For now, collared aracaris remains a captivating sight, a splash of colour and a burst of life amidst the sprawling branches.Desktop Version

Its Bourtzi tower, an extension of the fortress standing on a small islet, was once connected to the main castle by a stone bridge.Desktop Version

Everglades National Park, Florida, USA
On this day, 90 years ago, an act was passed that would lead to the creation of one of America"s natural gems: The Everglades National Park. This park in Florida encapsulates the largest subtropical wilderness of the United States. The Everglades, spanning across more than 6,100 square kilometres, are a lifeline to 36 federally protected and endangered wildlife, from the gentle manatee to the stealthy Florida panther. Here, the air thrums with the calls of over 350 bird species like limpkins and snail kites, while the waters teem with life too: fish, like snook and redfish, and American crocodiles are all found here. Beyond its biodiversity, the park has earned global recognition, celebrated as a UNESCO World Heritage Site, an International Biosphere Reserve and a Wetland of International Importance.Desktop Version

Found in tropical oceans around the world, these filter feeders glide through the water, mouth wide open, straining plankton and small fish.

Joshua Tree National Park, California, USA
Joshua Tree National Park, California, USA
California"s Joshua Tree National Park, located where the Mojave and Colorado deserts meet, has been home to various cultures for thousands of years. Its earliest known residents were people from the Pinto culture, who lived here from 8000 to 4000 BCE. Centuries later, this land was inhabited by the native Cahuilla, Serrano and Chemehuevi peoples. The park"s namesake, the Joshua tree, grows in a landscape covering 3,216 square kilometres. Despite their name, they are not really trees but rather a kind of succulent. Native to the southwest US and northern Mexico, they can grow up to 12 metres tall. Whether it"s hiking through Hidden Valley, visiting the Cholla Cactus Garden or marvelling at Skull Rock, this national park has a lot to offer. By night, it becomes a stargazer"s paradise, as seen in today"s image. Whether you seek adventure or a moment of tranquillity, Joshua Tree awaits with open skies.Desktop Version

Aït Benhaddou, Morocco
Are you looking for sandy charms? Come to Aït Benhaddou, Morocco, situated along the old caravan route linking the Sahara to Marrakesh. This UNESCO World Heritage Site showcases Moroccan earthen clay architecture, a building technique that uses sun-dried mud to make structures. Although none of the buildings here are believed to predate the 17th century, they are constructed using techniques and styles that are much older. Located on the gentle slopes overlooking the Asif Ounila (Ounila River) is the ksar, a fortified village of Aït Benhaddou, with mud-brick structures. Clustered within a defensive wall with a gate and corner towers, ksars are a great representation of classic pre-Saharan dwelling.

International Day for Biological Diversity
International Day for Biological Diversity
Today we"re celebrating the biodiversity of our planet! What exactly is biodiversity? It refers to all living things, from animals and plants to fungi and microorganisms, in one area. This delicate but vigorous balance in nature is what keeps us all alive. That"s definitely worth celebrating! May 22 was officially declared to be the International Day for Biological Diversity by the United Nations in 2000. Unfortunately, the biodiversity of Earth is slowly decreasing due to climate change, the draining of natural resources, urbanisation and pollution, among other factors. It is our responsibility to return nature"s favour to us and protect our environment. After all, we are blessed with intriguing species such as the Tasmanian snow gum—the tree seen in today"s image—which takes root in one of the most biologically diverse places on the planet, the Mount Field National Park in Tasmania, Australia.Desktop Version
Coral Reef Awareness Week
Coral Reef Awareness Week
Blooming pillar corals, green sea turtles and colourful reef fishes—welcome to the thriving underwater universe of coral reefs. Running from July 15 to 21, Coral Reef Awareness Week is the perfect time to honour them. Coral reefs are formed by tiny marine organisms called coral polyps, which create vast colonies that serve as homes to a diverse array of marine species. As we turn our attention to their beauty and benefits, it"s vital to recognise the lurking threats–climate change, pollution and harmful human activities.Desktop Version
