Aurora are colorful lights in the night sky and primarily appear in Earth’s polar regions. But what causes these colorful lights?.
When solar plasma is ejected from the Sun during a magnetic event like a flare or a coronal mass ejection, the plasma travels outward along with the solar wind and when it encounters Earth’s magnetic field, it travels down the field lines that connect at the poles.
Atoms in the plasma interacts with atoms in Earth’s upper atmosphere, creating colorful dancing lights. Currently, with all the solar activity, lower than normal latitudes may see aurora.
