这些雪永远不会融化 This snow will never melt
White Desert National Park, Egypt
Snow, in the desert? Not quite. Today we're in Egypt's White Desert, which gets its colorful name from an abundance of chalk, limestone, and quartz rock formations that give the sand its special hue. Tourists flock to this place to see these naturally occurring structures, honed over thousands of years into unique shapes through a process known as 'differential weathering.' Located about five hours to the southwest of Cairo, White Desert National Park is a lot more than just deteriorating rocks—it's also a protected refuge for several endangered animal species.
真相就在那里，但不是在这块石头上 The truth is out there…but not on this rock
Graffiti near Santa Fe, New Mexico
Evidence of ancient aliens? Nah, more likely the etchings of a prankster hiker. Though Pueblo cultures here in northern New Mexico made pictographs in this style several centuries ago, there's no evidence they were depicting extraterrestrials. But don't get us wrong: We want to believe.
Today is Extraterrestrial Culture Day, a holiday that enjoys official status in New Mexico thanks to the 'Roswell incident' of 1947. Depending who you ask, the metallic wreck found on a remote ranch in New Mexico one July morning was either a weather balloon, a top-secret military device disguised as a weather balloon, or a bona fide alien craft. Whatever the truth, the nearby town of Roswell has gone all-in on UFO lore. It's home to numerous UFO-themed attractions, chief among them the International UFO Museum and Research Center.
An island hopper's paradise
Welcome to the sunny and sultry Seychelles, a tropical island nation just south of the equator in the Indian Ocean, roughly 900 miles off the eastern coast of Africa. The gorgeous beach you see here is the Anse Source d'Argent on the island of La Digue, one of 115 islands that make up this tropical republic. Anse Source d'Argent has long been a favorite of photographers, who are drawn to its contoured, dark granite boulders, pristine white sand, and turquoise-colored water. Beachcombers and sun worshippers also flock to the Seychelles because of the islands' consistently great weather—daily high temperatures almost always stay within a comfortable range of between 75 and 90 degrees Fahrenheit all year round.
Most any day is a day worth celebrating in the Seychelles, but today is cause for double celebration: June 29 is Independence Day in the Seychelles, commemorating the nation's 1976 independence from centuries of colonial rule under the French and British. It also happens to be the UN's International Day of the Tropics, a day of special recognition for the Seychelles and other locales within the zone between the tropics of Cancer and Capricorn. That accounts for about 36% of Earth's land mass and close to 40% of its population. The intent of International Day of the Tropics is twofold: as a celebration of the extraordinary diversity of this zone while also highlighting the challenges facing the region, like poverty, climate change, deforestation, urbanization, and demographic shifts.
