What would Aurora look like if no magnetic field was present around the Earth?
I was looking through some sites and came across this - https://www.livescience.com/earth-magnetic-field.html
This clearly mentions how, if the magnetosphere surrounding the Earth weakens, the Auroras might penetrate into the Atmosphere and light up the skies closer to the equator. So, I also looked it up but, to my astonishment, I found no sources that answered this question to my satisfaction.
Though, intuition says that If there is no Magnetosphere, there should be no Aurora either.
