A Vortex Aurora over Iceland

No, the automobile used to be not in hazard of being vacuumed into home by the fantastic sky vortex. For one motive, the vortex used to be basically an aurora, and since auroras are created by particles inserting the Earth from home, they receive not assemble a vacuum. This without warning atmosphere up auroral expose used to be precipitated by a Coronal Mass Ejection from the Solar that passed by the Earth closely satisfactory to motive a ripple in Earth’s magnetosphere. The upper crimson parts of the aurora occur over 250 kilometers excessive with its crimson glow created by atmospheric atomic oxygen straight away energized by incoming particles. The lower inexperienced parts of the aurora occur over 100 kilometers excessive with its inexperienced glow created by atmospheric atomic oxygen energized not straight away by collisions with first-energized molecular nitrogen. Below 100 kilometers, there may perhaps be minute atomic oxygen, which is why auroras discontinue without warning. The concentric cylinders depict a dramatic auroral corona as considered from the aspect. The featured image used to be constituted of a single 3-second publicity taken in mid-March over Lake Myvatn in Iceland. April is: Global Astronomy Month
