This Is Why … auroras are only found at the poles by Joanne O’Meara


If you’ve ever had the pleasure of seeing the northern lights in person, you know that words do not do them justice. The auroras (aurora borealis in the north, aurora australis in the south) are beautiful and haunting, moving across the night sky as ethereal light. The displays are typically green, but occasionally you’ll see hints of red, pink, or purple. Why do we only see them at the extremes of our planet – near the poles – and why these specific colours?
