World Space Week
World Space Week
From October 4 to 10, World Space Week invites us to transcend our earthly bounds and chase the stars. It was born from the launch of Sputnik 1 by the USSR in 1957 and the signing of the Outer Space Treaty in 1967, a pioneering international commitment to peaceful cosmic exploration. During this week, classrooms buzz with experiments, planetaria echo with wonder and telescopes bridge the gap to distant galaxies. Together, these moments weave a universal story of science, discovery and humanity"s relentless drive to push boundaries. The week"s mission is clear: to ignite the next generation of explorers, engineers and dreamers ready to rewrite the cosmos.Desktop Version
Staghorn coral in shallow ocean
Staghorn coral in shallow ocean
Coral reefs—like the staghorn coral pictured here—are home to roughly 25% of all marine species, despite covering less than 1% of the seafloor. These ecosystems not only support ocean biodiversity but also protect coastlines and drive economies through tourism and fishing. But coral reefs are in crisis. Warming oceans, pollution and overfishing have put over 70% of coral reefs at risk—a figure expected to rise in the coming years.Desktop Version

Colourful beehives, Italy
Colourful beehives, Italy
If you think bees are just out for a sting, think again. These tiny winged workers are running the world"s sweetest gig. About 35% of global food crop production relies on animal pollination—and honey bees are among the most important contributors. The value of crops pollinated by bees is estimated at hundreds of billions of dollars each year. But despite their superpowers, bees are in a sticky situation. Today"s image shows a row of colourful beehives in Italy. Bees use colour to distinguish between hives, much like humans use house numbers. Blue, yellow, green and red hives help reduce confusion and prevent accidental hive invasions.Desktop Version

Autumn equinox
Autumn equinox
Autumn isn"t just marked by the calendar. Each September, Earth"s subtle tilt brings the autumn equinox—one of two times a year when day and night are nearly equal in length. It marks the beginning of autumn in the Northern Hemisphere. From solar alignments to changing leaves, nature offers its own quiet signals that the season has shifted. While for most of us it may seem like just another day, ancient cultures paid close attention to this change. Sites like Chichén Itzá in Mexico and England"s Stonehenge were designed to align with the rising or setting sun during equinox days.Desktop Version

International Literacy Day
International Literacy Day
Read it and believe it—literacy changes everything. As a basic human right, literacy is a powerful tool that opens the door to greater freedoms and active global citizenship. India"s National Literacy Mission sees literacy as more than just knowing how to read, write and do basic arithmetic—it"s about putting those skills to work in everyday life. Functional literacy means understanding the causes of deprivation and working to change them. It involves gaining skills to improve one"s economic status and overall well-being. Recognising its far-reaching impact, International Literacy Day—observed each year on September 8 since 1967—serves as a reminder of how vital literacy is in building a better, more sustainable future for all. This year, the theme explores literacy in a digital age, where technology continues to reshape how people learn, communicate and participate in society.Desktop Version
International Day for the Conservation of the Mangrove Ecosystem
International Day for the Conservation of the Mangrove Ecosystem
As twilight descends on Walakiri Beach on the island of Sumba, Indonesia, the silhouettes of mangrove trees stand like sentinels in the tide—graceful, resilient and vital. Today, on International Day for the Conservation of the Mangrove Ecosystem, we honour these extraordinary trees and the critical role they play in sustaining life on our planet. Mangroves are nature"s coastal guardians. With their arching and salt-filtering roots, they thrive where few trees can—anchored in brackish water, enduring tides and shifting sands. They protect shorelines from erosion, buffer communities against storms and serve as nurseries for countless marine animals. Their tangled root systems not only stabilise sediment but also provide shelter for juvenile fish, crabs and birds.Desktop Version
World Population Day
World Population Day
We are living in a full house, and it is getting fuller. With 8.2 billion people and counting, World Population Day highlights how that growth affects cities, food and the future. First observed in 1989, the day focuses on how unchecked population growth affects sustainability. The event was inspired by Five Billion Day in 1987, which marked the approximate date when the global population hit that milestone. As cities expand, green spaces shrink and agriculture competes for limited land and water resources. But there is a way forward—investing in education, improving access to healthcare and building smarter cities can balance growth with sustainability.Desktop Version

Badlands National Park, South Dakota, United States
Badlands National Park, South Dakota, United States
As the sun sets over Badlands National Park, the landscape transforms into a stunning display of colour. The national park, located in southwestern South Dakota, United States, features a dramatic terrain of eroded buttes, pinnacles and spires carved by millennia of wind and water. Spanning over 950 square kilometres, the park is divided into three main units: the North Unit, home to the visitor centre and scenic Badlands Loop Road; and the Stronghold and Palmer Creek units. The park"s dramatic terrain is the result of sedimentary rock layers eroding at a rate of about two centimetres per year, revealing colourful bands of volcanic ash, silt and clay. These formations are not only visually striking but also rich in fossils, including remains from the Oligocene Epoch (about 33.9 to 23 million years ago), such as ancient horses, camels and sabre-toothed cats.Desktop Version
Shark Awareness Day
Shark Awareness Day
Sharks have been around for over 400 million years—outlasting dinosaurs, surviving ice ages and weathering mass extinctions. They are symbols of ocean health, which is why Shark Awareness Day draws attention to these apex predators that help maintain balance in marine ecosystems. Protecting sharks means preserving the health of entire ocean environments—and ultimately, securing a sustainable future for all life. Take the blue shark, featured here, for example—sleek, wide-ranging and undeniably captivating. It"s the only living member of its genus, and it prefers the deep waters of temperate and tropical oceans. Blue sharks are famous for their epic migrations—some travel from New England to South America, guided by seasonal changes, food availability and favourable environmental conditions.Desktop Version

International Rock Day
International Rock Day
Do you think rocks are just … well, rocks? These natural mineral combinations have done more than just sit around—they"ve built the Earth"s crust and helped humans shape history. From Stone Age tools to the minerals powering modern civilisation, rocks have been essential throughout our journey. International Rock Day celebrates this enduring impact, inviting us to explore the science of rocks, admire their natural beauty and recognise the rich variety they add to our world. If you"re wondering where to see geology in action, Iceland is a great place to explore. Today"s image takes us to Kálfshamarsvík—a secluded cove on the country"s remote Skagi peninsula. Unlike Iceland"s famous black sand beaches, this cove"s shore is strewn with large, smooth pebbles, while its fiery volcanic past still reveals itself in the towering cliffs. Here, evidence of volcanic activity is on full display in the form of rare hexagonal basalt columns.Desktop Version
World Nature Conservation Day
World Nature Conservation Day
Every July 28, World Nature Conservation Day reminds us that protecting nature isn"t optional—it"s essential. Mongolia"s vast grasslands, featured today, are a powerful example. These ecosystems are among the largest intact temperate grasslands on Earth, stretching thousands of square kilometres of open steppe. They support around 200,000 nomadic herder families and provide habitat for rare species like the Mongolian gazelle and snow leopard. While the day isn"t tied to a single founding organisation, it aligns with the mission of global conservation leaders like the International Union for Conservation of Nature (IUCN), which has worked to protect biodiversity since 1948.Desktop Version
