Black Aurora
Scientists have discovered a strange phenomenon called "black aurora." Unlike the colorful northern lights we often see, black auroras appear as dark patches in the sky. They happen when certain forces from space and Earth interact, causing areas where there is less light. Researchers are still studying this mysterious event to understand exactly how it works.
Strange Chimney Vents On Sea Floor
Scientists exploring the bottom of the Dead Sea found strange, chimney-like structures called "white smokers." These chimneys, which are 2 to 3 meters wide and up to 7 meters tall, release shimmering plumes of fluid. The fluid comes from freshwater sources beneath the sea that dissolve the surrounding salt, creating these unique formations. Researchers believe that new clusters of these chimneys can help predict where dangerous sinkholes might form in the region.
Why Dolphins Swim In A Ship's Bow Wave
Scientists have long wondered why dolphins enjoy riding the waves created by boats, known as bow waves. Recent research suggests that dolphins may do this to conserve energy. When dolphins swim quickly, they need to breathe more often. However, while riding bow waves, their breathing rate decreases, indicating they use less energy. This behavior allows dolphins to travel efficiently by taking advantage of the moving water pushed by boats.
