What you need to know about northern lights
The aurora borealis, known commonly as northern lights, is a colourful display of light in the sky. It was named after the roman goddess of dawn Aurora. It is predominantly seen in the far northern regions. Aurorae are caused by cosmic rays or solar winds interacting with the upper atmosphere. The charged particles from those events enter the earth’s atmosphere and cause the pretty lights in colours of greens, pinks, yellows, blues, and reds. You can mostly see them at night and between September and the middle of April, because the nights are darker and the lights more visible therefore.
