Asteroid Day
Asteroid Day
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 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.Desktop Version

Snippet They wear white after Labor Day—and all year long—with zero shame. Meet the great egret, also known as the great white egret.

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. With many shark species facing the threat of extinction, this day is all about appreciating their ancient legacy and learning how we can help keep them off the endangered list.Desktop Version
Spotted eagle rays in the Galápagos Islands
Spotted eagle rays in the Galápagos Islands
It"s a bird, it"s a plane, it"s … a fish! Gliding through the ocean with flapping fins and polka-dot flair, the spotted eagle ray refuses to blend in. It doesn"t crawl along the seabed like its stingray cousins—it flies underwater. The species gets its name from—you guessed it—its protruding snout, which resembles an eagle"s beak, and its distinctive spotted back, which is unique to each individual, much like fingerprints. Their wing-like pectoral fins can span up to 10 feet. Near the base of the long tail are venomous spines, in case a predator gets too close. These rays aren"t aggressive, but they"re not defenseless either.Desktop Version
A Eurasian red squirrel in Switzerland
A Eurasian red squirrel in Switzerland
Quick, clever, and always on the move—meet the Eurasian red squirrel, a leafy treetop resident found across much of Europe and Asia. While it prefers the shelter of forests, this agile creature easily adapts to gardens and parks. It builds its nest, called a drey, high in the fork of a tree using twigs to form a domed structure about 10 to 12 inches wide. The female featured here is gathering moss—one of several soft materials, along with bark, leaves, and grass, that line the nest and turn it into a snug, well-insulated retreat. These rodents may also take over tree hollows or abandoned woodpecker holes when available.Desktop Version
Devils Tower National Monument, Wyoming
Devils Tower National Monument, Wyoming
Somewhere in the wide prairies of northeastern Wyoming stands Devils Tower, a stone formation that rises from the open plains. Once called Bear Lodge, the butte gained its current name during an 1875 expedition led by Colonel Richard Irving Dodge, possibly after an interpreter mistranslated a Native phrase as "Bad God"s Tower." The missing apostrophe in its official title follows standard geographic naming conventions—hence, the signs read "Devils Tower." In 1906, President Theodore Roosevelt proclaimed it the nation"s first national monument; a milestone whose anniversary falls today.Desktop Version

Get ready for one of the most dazzling celestial displays of the year—the Perseid meteor shower. Active from mid-July through late August, this year it reaches its spectacular peak on the night of August 12 and into the early hours of August 13. The Perseids light up the skies when Earth passes through a trail of icy and rocky debris left behind by Comet Swift–Tuttle, which last passed close to our planet in 1992. These meteors are called the Perseids because they appear to streak from the direction of the constellation Perseus.Desktop Version

Old City of Dubrovnik in Dalmatia, Croatia
Old City of Dubrovnik in Dalmatia, Croatia
There is something mesmerizing about cities that wear their history on their sleeves—and Dubrovnik, Croatia, is one of them. Once known as the independent Republic of Ragusa, this city was a major maritime power and trading hub from the 14th to the 19th century. Situated in southern Dalmatia along the Adriatic Sea, its success was built on diplomacy and seafaring. The Walls of Dubrovnik, built between the 13th and 17th centuries, stretch for over 1.2 miles, with towers, forts, and bastions still standing strong. The current layout of the walls follows a city plan from 1292, when Dubrovnik was rebuilt after a fire under Venetian rule.Desktop Version
