Space station sensors saw how weird 'blue jet' lightning forms
February 2, 2021 at 6:30 am Scientists have finally gotten a clear view of the spark that sets off a weird type of lightning called a blue jet. Lightning bolts usually are seen zipping from thunderclouds down toward the ground. But blue jets shoot up from clouds. They ascend high into a layer of the atmosphere called the stratosphere. In less than a second, a blue jet can reach about 50 kilometers (31 miles) above the ground. In the stratosphere, this electricity excites mostly nitrogen gas. That nitrogen glows blue, giving these jets their signature color. Blue jets have been seen from the g...
