The northern lights, also known as the aurora borealis, are mesmerizing ribbons of light that have fascinated humanity for thousands of years. Despite their serene beauty, this breathtaking display results from a highly energetic and turbulent process. The aurora forms when charged particles from the sun collide with Earth's upper atmosphere at incredible speeds — up to 45 million mph (72 million kph). Thankfully, our planet's magnetic field acts as a protective shield, preventing these solar particles from causing harm while creating the stunning spectacle we know as the northern lights. What causes the northern lights? The northern lights give us a unique window into our sun's activity, space weather and Earth's magnetic field. At any given moment, the sun is ejecting charged particles from its corona, or upper atmosphere, creating the solar wind. When that wind slams into Earth's ionosphere, or upper atmosphere, the aurora is born. small particles traveling down the magnetic field lines at the north and south poles into Earth's atmosphere. There, the particles interact with gases in our atmosphere resulting in beautiful displays of light in the sky. Oxygen gives off green and red light. Nitrogen glows blue and purple.Inn the Northern Hemisphere, the phenomenon is called the northern lights (aurora borealis), while in the Southern Hemisphere, it's called the southern lights (aurora australis). Auroras are not just something that happen on Earth. If a planet has an atmosphere and magnetic field, they probably have auroras. as amazing aurira ve been observed on Jupiter and Saturn
