When these photo voltaic winds, composed primarily of electrons and protons, collide with the Earth’s magnetic discipline, one thing extraordinary occurs. The Earth’s magnetic discipline acts as a protect, deflecting most of those particles. Nevertheless, a few of the charged particles are funneled alongside the magnetic discipline traces in direction of the poles.
As these energetic particles descend into the Earth’s environment, they collide with atoms and molecules of varied gases. The most typical gases concerned are oxygen and nitrogen. These collisions energize the atmospheric gases, inflicting them to emit mild. The colour of the sunshine is determined by the kind of gasoline and the altitude at which the collisions happen.
Oxygen, when energized, primarily produces inexperienced and purple mild. Inexperienced is the commonest coloration of the aurora, sometimes seen at decrease altitudes. Purple is much less frequent and infrequently seems at larger altitudes. Nitrogen, when energized, creates blue and violet mild. These combos and variations produce the gorgeous, ever-changing show of colours we all know because the Northern Lights.
Shapes and Colours of the Aurora
From ribbons and arcs to rays and coronas, the shapes and types of the aurora are endlessly dynamic. The lights can shimmer, dance, and pulsate throughout the sky, making a mesmerizing efficiency that is distinctive with each look.
