World Rivers Day
World Rivers Day
On World Rivers Day, we honor what may be thought of as the queen of them all—the Amazon, which flows more than 4,000 miles mostly through the South American countries of Peru and Brazil. The Amazon discharges a whopping 58 million gallons of fresh water into the ocean every second, enough to fill 83 Olympic-sized swimming pools, far more water than any other river in the world. It accounts for 20% of all fresh water that flows into the world"s seas and oceans. It"s also the vital heart of the largest and most diverse rainforest in the world. The Amazon rainforest is home to a third of the world"s animal species and its trees and plants pull billions of tons of heat-trapping carbon dioxide from the atmosphere each year, making it one of the Earth"s best defenses against climate change.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

National Library Week
National Library Week
Libraries are magical places. They are home to books full of stories and knowledge, provide easy access to resources that might not be affordable for all, and offer spaces for book clubs, author talks, and other social gatherings. Without a doubt, our society benefits from libraries in several ways. To motivate people to read and take advantage of these institutions, the National Book Committee initiated an event series. The first National Library Week was celebrated in 1958 with the action slogan, "Wake Up and Read!" This year, the annual National Library Week starts on April 6, which coincides with National Library Day. Some libraries will amaze us not only with their collection of books but also with their architecture. The George Peabody Library at Johns Hopkins University in Baltimore has earned the prestigious nickname, "the cathedral of books."

Badlands National Parks 45th anniversary
Badlands National Parks 45th anniversary
The strange stripes in our homepage image reveal tiers of fossil beds in Badlands National Park in South Dakota. Beneath the multicolored surface lies the land"s history, including the remains of ancient horses, camels, tigers, and rhinos. The barren landscape, dotted with pinnacles and prairies, was formed by two geological processes: deposition, where the layered rocks were gradually stacked up on top of each other by inland seas, winds, and rivers over millions of years, and erosion, which began about 500,000 years ago. The Red Shirt Table, at 3,340 feet, is the highest point in the park, which was established on this day in 1978. It protects 379 square miles of rocky buttes, pinnacles, and prairies. This inhospitable terrain was called "Mako Sica," or "land bad" by the Oglala Lakota people, who have lived here for hundreds of years. Still thirsty for knowledge? Visit the national park"s museum collection. There are over 360,000 objects that have a lot more to reveal!Desktop Version
