Blue hour in Trondheim, Norway
Blue hour in Trondheim, Norway
In Norway, winter isn"t just a season—it"s an experience. In the north of the country, nights stretch for 20 hours, and there are entire weeks when the sun remains hidden below the horizon. It might sound bleak, but it"s a unique time of the year. Why? Because around early afternoon, usually between 1 and 2 PM, a soft, lingering light reflects off the snow-covered ground and the deep blue sea. This forms a breathtaking, glassy blue glow that settles over the landscape. Each day, the blue hour arrives just a little later, a gentle reminder that the sun is slowly preparing to reclaim the sky.Desktop Version

Lake Tyrrell, Victoria, Australia
Lake Tyrrell, Victoria, Australia
At Lake Tyrrell, in southern Australia, the sky meets the Earth in a dazzling display. The state of Victoria"s largest salt lake was formed around 120,000 years ago. Over time, climate changes caused water levels to drop; these days, the lake is normally dry, except in winter when it"s covered in about 2 inches of water. The name "Tyrrell" comes from the local Wergaia word for "sky," a nod to the Boorong Aboriginal People"s interest in astronomy. Spanning more than 70 square miles, Lake Tyrrell is a haven for wildlife, including kangaroos, emus, and various reptiles.Desktop Version
Pride Month
Pride Month
On June 28, 1969, protests erupted over a police raid at the Stonewall Inn, a gay bar in Greenwich Village in New York. This watershed moment—at a time when homosexuality was still illegal in most US states—launched an era of activism and resistance that would transform into a celebration of LGBTQIA+ love and pride. Today, Pride Month is observed in the United States and in dozens of countries around the world. Taking place every June, the month-long celebration of LGBTQIA+ communities also highlights their struggles and achievements. The goal of Pride is to promote the acceptance of love in all its forms, so that LGBTQIA+ communities have the respect, dignity, and equality they deserve.Desktop Version

Vernazza, Cinque Terre, Liguria, Italy
Vernazza, Cinque Terre, Liguria, Italy
Perched on the rugged cliffs of the Italian Riviera, Vernazza is one of the five villages of the Cinque Terre area of northwestern Italy. Here, ancient buildings stand along the coastline of the Ligurian Sea, and life is filled with the hustle and bustle of the fishing industry. Vernazza got its name from the indigenous wine, "vernaccia," meaning "local" or "ours." One of the best-known monuments in the area is the medieval Doria Castle, built as a defensive fortress to protect the village from frequent pirate attacks. Thanks to the construction of the Genoa–La Spezia rail line in the 19th century, the village became more accessible by land. The car-free cobblestone streets are ideal for walking around. While here, you might want to visit the Chapel of Santa Marta and the Sanctuary of Madonna di Reggio. Vernazza is sometimes described as the pearl of the Cinque Terre with its natural port, colorful houses, and green terraces overlooking a sparkling sea.Desktop Version
South Stack Lighthouse, Holy Island, Wales
South Stack Lighthouse, Holy Island, Wales
Built on the rugged cliffs of Holy Island, Wales, the South Stack Lighthouse stands watch over the deep waters of the Irish Sea. The 91-foot-tall white tower has guided sailors since its completion in 1809; it provides safe passage for ships on the Dublin-Holyhead-Liverpool route. When it was built, sperm whale oil was used to light the lamps; however, over the years, the mechanism has been upgraded to more advanced technology like LED bulbs and Fresnel lenses. Automated in 1984, the lighthouse continues to serve as a vital navigational aid, with its powerful beam shining up to 28 miles. As the sun sets and the sky fills with colors, the silhouette of the South Stack Lighthouse in the dusk makes for a stunning sight. Visitors brave the 400-step descent down the steep cliff face to explore the lighthouse, including its engine room and exhibition area.Desktop Version
National Napping Day

Feeling a bit tired? You"re not alone—losing an hour to daylight saving time can leave anyone groggy. That"s why Napping Day exists. Introduced in 1999 by William Anthony, a Boston University professor, and his wife, Camille, this unofficial holiday encourages everyone to take quality naps.

Brown-throated three-toed sloth in cecropia tree, Costa Rica
Brown-throated three-toed sloth in cecropia tree, Costa Rica
Costa Rica"s forests are habitats for two sloth species: Hoffmann"s two-toed sloth and the star of today"s homepage, the brown-throated three-toed sloth. Despite being larger than many other tree-dwelling mammals, three-toed sloths have adapted by reducing their muscle mass and size to thrive on treetops. Their large stomachs have four chambers, which, when full, account for about 30% of their body weight. These shaggy critters are so sedentary that algae grow on their coats, which helps to camouflage them within the rainforest canopy. In 2021, these slow-moving creatures were declared national symbols in Costa Rica. Then-president Carlos Alvarado signed the initiative into law to emphasize the sloths" importance in the country"s ecosystem.Desktop Version

Camel milk is a valuable and nutritious ingredient in many recipes in the region, while camel racing keeps people entertained to this day, illustrating the versatility of these hardy creatures.Desktop Version
