Each scar on Earth from a meteorite impact tells a story—from the asteroid that wiped out the dinosaurs to the lesser-known craters that dot the planet. Asteroid Day highlights ongoing research into asteroids and the potential threats they pose. Started in 2015 and backed by the United Nations, this day marks the anniversary of the Tunguska event—a massive explosion that occurred in Siberia on June 30, 1908. This explosion flattened over 800 square miles of Siberian forest near the Tunguska River. The blast released energy equal to 10–15 megatons of trinitrotoluene (TNT), a standard measure of explosive force. Since then, craters like Arizona's Barringer, Quebec's Manicouagan and others have helped scientists study what happens when space rocks hit Earth.

Every June 29, the International Day of the Tropics shines a light on the equator-hugging zone where the sun sticks around and climate conversations get real. The tropics span a broad region between the Tropic of Cancer and the Tropic of Capricorn, including parts of Asia, Africa, Oceania, Central America and South America. Nearly 40% of the global population lives in this band, which also hosts 80% of the world's biodiversity. It's rich in culture, nature and history—but also under pressure from rising temperatures, deforestation and fast-paced urban growth.

The Mesquite Flat Sand Dunes, located near Stovepipe Wells Village in Death Valley National Park, California, are the most accessible and iconic dunes in the park. They are formed by a combination of eroding mountains to the north that supply sand, prevailing winds that move it and surrounding mountains that trap it from the south—creating a stunning landscape of rippling sand hills. Named after the resilient mesquite trees that grow here, the dunes offer breathtaking views at sunrise and sunset, as well as exceptional stargazing opportunities.

Don't let the name fool you—this frog isn't just leafing around. The splendid leaf frog, or splendid treefrog, is a rainforest resident with a flair for the dramatic: neon legs, sticky feet and a disappearing act. One minute it's a humble green leaf, the next it's a flash of colour mid-leap, startling predators. This frog lives high in the canopies of Central and South America, especially in Costa Rica, Panama and parts of Ecuador and Colombia. This amphibian is a nocturnal ninja, spending its days snoozing on leaves and its nights foraging for insects. With vertical pupils and a golden glow, its oversized eyes help this frog spot prey in the dark. Thanks to sticky toe pads and strong limbs, it can cling to branches and leaves like a pro, even in the canopy's slippery heights.

You can lead a horse to water, but you can't make it drink—unless, of course, you're talking about Horse Head Rock, perched off the Sapphire Coast near Bermagui in New South Wales, Australia. This ancient formation, pictured here, seems as if nature itself has sculpted a mythical creature forever poised to drink from the sea. Estimated to be 500 million years old, the rock's uncanny resemblance to a horse bending its neck is the result of wind and wave erosion. As one of the region's oldest and most iconic landmarks, it attracts hikers, photographers and nature lovers year-round. The best views are from the elevated track between Camel Rock and Murunna Point, while the more daring can scramble around from Camel Rock Surf Beach, though only safely at low tide.

As the sun rises over the hills in Somerset, Glastonbury Festival comes alive, transforming a quiet part of South West England into one of the world's most famous music destinations. Since its humble beginnings in 1970, when tickets cost just £1, Glastonbury has grown into a cultural powerhouse, attracting over 200,000 fans each year. The festival is deeply rooted in the ideals of the hippie movement, the 1960s counterculture and the free festival spirit that sparked its early days. From David Bowie and Elton John to Metallica and Billie Eilish, Glastonbury's stages have hosted performances that have defined generations. This year's festival runs from today through June 29, with The 1975, Neil Young and Olivia Rodrigo topping the bill. Overlooking the event is Glastonbury Tor, pictured here, a hill crowned by the 14th-century St. Michael's Church Tower. The Tor is steeped in myth and legend, from ties to King Arthur's Avalon to ancient spiritual lore.

This place wasn't built overnight—nature took its time to craft this masterpiece. What you see at Arches National Park in Utah, United States, is the result of over 300 million years of erosion, uplift and weathering. These arches were formed when salt beds were left behind by ancient seas. Over time, layers of sandstone cracked, shifted and slowly wore away, revealing more than 2,000 natural arches. These formations are made mostly of Entrada and Navajo sandstone. The park was recognised as a national monument in 1929 and was later upgraded to national park status in 1971.

Berlin gets the buzz, Munich brings the beer, but what about Dresden, in Saxony, Germany? Dresden brings the story. The city, once called 'the Florence on the Elbe,' was nearly wiped off the map in 1945 during World War II. Since then, it has rebuilt itself into a place where modern museums, Baroque buildings and riverside views share the same frame. Much of the city's oldest architecture can be found in the boroughs of Altstadt (Old Town) and Neustadt (New Town). The surrounding neighbourhoods, originally planned by Saxon monarchs in the 18th and 19th centuries, are named after Saxon sovereigns like Friedrichstadt and Albertstadt.

World Rainforest Day is not just a calendar event—it's a call to action. Established in 2017 by Rainforest Partnership—a nonprofit environmental organisation—the day raises awareness about the importance of rainforests and mobilises efforts to protect them.

Experience the magic of the summer solstice at Seljalandsfoss waterfall in Iceland. Today, the Northern Hemisphere celebrates the longest day of the year, when the sun reaches its highest point in the sky. Seljalandsfoss, located along Iceland's South Coast, offers a stunning backdrop for this astronomical event. The 60-metre waterfall drops from cliffs that once marked the country's coastline. The cascading water is part of the Seljalandsa River, originating from the volcanic glacier Eyjafjallajökull. The volcano under the icecap last erupted in 2010, causing disruption for locals and air traffic.

Maasai giraffes, known for their distinctive, jagged blotches, are native to East Africa. Besides Kenya and Uganda, they roam the vast plains of Tanzania's Serengeti, a name derived from the Maasai word 'seringit,' meaning 'endless plains.' Today's image captures a tender moment between a Maasai giraffe mother and her calf in this stunning landscape. The Maasai giraffe is easily recognised by its jagged, irregular spots and inhabits various regions across eastern Africa. It is the largest giraffe species and the tallest land animal on Earth. Males typically weigh up to 1,300 kilograms and can reach heights of 5.5 metres. In the wild, they live around 30 years, often longer in captivity. A notable feature is their long necks, made up of seven vertebrae, which accounts for about one-third of their total height.

The Five Towers rise majestically in the heart of the Dolomites in the province of Belluno in the Veneto region of Italy. They offer the perfect refuge from the summer heat and crowded beaches. Each tower has its own story to tell of ancient civilisations, adventurous hikers, daring climbers and distant battles. Shaped by time and weather, these Dolomite spires played a strategic role during the First World War, and it is still possible today to explore the trenches and remnants of that conflict-scarred past.

Pollinator Week is in full bloom! This year's celebration takes place from June 16 to 22. It shines a spotlight on the birds, bats, bees, butterflies, beetles and other animals that help pollinate nearly 90% of flowering plants—including many of the fruits, vegetables and nuts we love. Featured here is the Asian swallowtail, beautifully captured on a red spider lily. Found across Northeast Asia and even parts of Hawaii, this striking butterfly uses its keen colour vision to find flowers, especially those from citrus families. While it is common and not currently threatened, its role as a pollinator is no less important.

Before you hit the beach, you'll hear it—the rustle of leaves in salty air, the creak of twisted trunks, the hush of an old world. Welcome to the maritime forest of Cumberland Island National Seashore on the southernmost stretch of Georgia's Atlantic coast. Salt spray, sandy soil, hurricanes? The trees here stand their ground. Live oaks bend but don't break. Saw palmettos crowd the ground like leafy bodyguards, while Spanish moss hangs from branches like nature's fringe. This maritime forest is one of the best remaining examples of this rare habitat in the United States. Thanks to its national seashore status, the island has been spared from the concrete creep seen on other coastlines.

They've got built-in helmets, a slow-and-steady vibe and zero interest in your deadlines. Sea turtles, like this one photographed in Fernando de Noronha, Brazil, have been cruising Earth's oceans since before T-rex was a thing. Today, World Sea Turtle Day, is about recognising these ancient navigators and the role they play in keeping our oceans in balance. Why June 16? The date marks the birthday of American conservationist Archie Carr, known as the 'father of sea turtle conservation.' His work laid the foundation for understanding turtle behaviour and fighting for their protection.

Long before neckties and greeting cards, Father's Day began with a daughter's quiet act of remembrance and steadfast love. In 1907, Grace Clayton, who lost her father in the Monongah mining disaster in West Virginia, United States, suggested a service to honour fathers who died in the incident. Although the idea didn't gain traction initially, it was revived in 1909 by Sonora Smart Dodd of Spokane, Washington, United States. She sought to pay tribute to her father, an American Civil War veteran who raised six children alone. Her determination sparked a movement, laying the foundation for the day we now dedicate to dads.
