Solar Storms and Auroras

The video explains auroras, beautiful light displays in the sky, known as aurora borealis in the Northern Hemisphere and aurora australis in the Southern Hemisphere. Auroras are caused by the sun's solar wind interacting with Earth's magnetic field, especially during solar storms. These interactions result in colorful lights in the sky. Auroras are not unique to Earth; they can also be found on other planets with magnetic fields and atmospheres, such as Jupiter and Saturn.
