Royal Portuguese Cabinet of Reading, Rio de Janeiro, Brazil
Royal Portuguese Cabinet of Reading, Rio de Janeiro, Brazil
Today we"re inside the Royal Portuguese Cabinet of Reading in Rio de Janeiro, Brazil, where the humble act of opening a book took on grand architectural ambitions. Founded in 1837 by 43 Portuguese immigrants, just 15 years after Brazil"s independence, the institution eventually moved into the building seen here, completed half a century later in a lavish Neo-Manueline style. Shelves soar over 20 metres around a vast reading room, crowned by a monumental stained-glass skylight that makes daylight part of the design.Desktop Version

Plitvice Lakes National Park, Croatia
Plitvice Lakes National Park, Croatia
Water seems to be everywhere at Plitvice Lakes National Park in Croatia. Sixteen terraced lakes are linked by a network of waterfalls, streams and cascades that wind through forested limestone canyons. The constantly changing colours of the water, ranging from emerald green to deep blue, are shaped by minerals, sunlight and ever-changing reflections. Established in 1949, Plitvice Lakes is Croatia"s oldest and largest national park. The landscape is famous for its tufa barriers, natural limestone formations created as mineral-rich water deposits calcium carbonate over centuries. These barriers continue to grow and change, gradually transforming the park"s waterfalls and lakes.Desktop Version

International Geodiversity Day
International Geodiversity Day
What if a mountain range could show you its geological history in stripes? At Zhangye National Geopark in China, the rocks do exactly that. Ridges roll across the landscape in bands of red, orange, yellow, brown and other earthy tones. Known as the Danxia landform, this striking landscape was shaped by layers of sedimentary rock deposited over geological time. Tectonic forces later lifted and folded the rocks, while weathering and erosion carved them into ridges, cliffs, gullies and peaks.Desktop Version

View of the Sanguinaires Islands from Corsica, France
View of the Sanguinaires Islands from Corsica, France
Just off the coast of Corsica, France, the Sanguinaires Islands rise from the Mediterranean as a small archipelago of four rugged, rocky islands. Viewed from a historic watchtower, they sit at the entrance to the Gulf of Ajaccio. Steep cliffs, centuries-old landmarks and sweeping sea views have drawn visitors to the area for generations. Though the farthest island lies only about 2 kilometres from shore, the archipelago feels surprisingly remote, surrounded by open water and shaped by wind, waves and salt spray.Desktop Version
Puzzlewood, Forest of Dean, Gloucestershire, England
Puzzlewood, Forest of Dean, Gloucestershire, England
What if a forest could keep you guessing at every turn? At Puzzlewood, near Coleford in the Forest of Dean, England, winding paths lead through twisted trees, moss-covered rocks and deep stone ravines. Its unusual rock formations, known as scowles, are natural geological features that were exposed and modified over time and later exploited for iron ore mining during the Roman period and possibly earlier. In 1848, a worker discovered more than 3,000 Roman-era coins hidden in earthenware jars inside a rock cavity, turning the woodland into a real-life treasure hunt.Desktop Version
International Archaeology Day
International Archaeology Day
Some discoveries start with a shovel. Others start with a drawing on a cave wall. International Archaeology Day celebrates both the detective work and the evidence behind them. Organised by the Archaeological Institute of America, this annual event began in 2011 and became International Archaeology Day in 2013 as participation expanded worldwide. Today, it brings archaeology closer to the public through talks, museum programmes, site visits, simulated digs and hands-on activities.Desktop Version
Sea otter, Monterey Bay, California, United States
Sea otter, Monterey Bay, California, United States
Few animals are both expert groomers and guardians of underwater forests. In today"s image, a sea otter grooms its fur in Monterey Bay, California—a daily ritual essential to its survival. Sea otters have the densest fur of any animal, with up to one million hairs per square inch. Unlike seals and whales, they have little blubber, so their thick, air-trapping coat provides insulation against the cold Pacific.Desktop Version
Eiffel Tower, Paris, France
Eiffel Tower, Paris, France
No other city is nearly as romanticised as Paris. Yet the French capital"s history has not always been as rosy as the sunset glowing behind the Eiffel Tower. Built for the 1889 Exposition Universelle, or the World"s Fair, which marked the centennial of the start of the French Revolution, the tower was originally intended to serve as the fair"s entrance centrepiece. Designed by engineer Gustave Eiffel and his team, the iron landmark rose more than 300 metres above the Champ de Mars and became the tallest structure in the world at the time.Desktop Version
World Space Week begins
World Space Week begins
First, you build a rocket. Then you ask it to leave Earth, fly to the moon, survive the trip and bring its spacecraft home. Simple, right? Well, not quite. World Space Week, observed every 4-10 October, celebrates the science that makes missions like this possible. The United Nations established the observance in 1999 to commemorate Sputnik 1"s launch on 4 October 1957, and the entry into force of the Outer Space Treaty on 10 October 1967. This year"s theme, "Rocket Revolution," focuses on the evolving technology driving space exploration.Desktop Version

Think of this as underwater hide-and-seek: the sea pen stands out while the crab blends in. Today"s image comes from the waters surrounding Komodo National Park in Indonesia, established in 1980 and named after the Komodo dragon, the world"s largest living lizard. The protected area includes islands, mangroves, seagrass beds and coral reefs. Located between the Pacific and Indian Oceans, the park is shaped by powerful currents that support a rich diversity of marine life, including species that rely on camouflage to survive.Desktop Version
Kasilof River, Alaska, United States
Kasilof River, Alaska, United States
Seen from above, the Kasilof River winds like a ribbon of turquoise through Alaska"s Kenai Peninsula in the United States. The vivid blue water comes from glacial silt carried downstream from Tustumena Lake, one of the largest freshwater lakes in the state. Flowing about 27 kilometres before emptying into Cook Inlet, the river is shorter than its famous neighbour, the Kenai, but no less remarkable.Desktop Version

Eryri National Park (Snowdonia) in Wales turns 75
If parks could keep birthday diaries, Eryri National Park (Snowdonia) in Wales would have quite the story to tell. The park turns 75 today, marking the anniversary of its designation in 1951. Eryri stretches across more than 2,100 square kilometres, with nine mountain ranges, about 120 kilometres of coastline and habitats ranging from peatlands and native woodlands to upland landscapes. At more than 1,000 metres, Yr Wyddfa is Eryri"s highest point. Nearby, the Carneddau and Glyderau add their own peaks, while Cadair Idris rises in the south. These protected landscapes provide habitats for wildlife and include 17 National Nature Reserves and 56 Sites of Special Scientific Interest.Desktop Version

Field of kochia plants, China
Field of kochia plants, China
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.Desktop Version
