Northern lights spectacle over Luxembourg
Northern lights put on a colourful spectacle over Luxembourg late Tuesday night, with the clear dark skies turning yellow, red, and violet.
Also called Auroras, this phenomena comes about when electrically charged particles of 'solar winds' hit the earth's atmosphere. When entering the particles become fluorescent, lighting up the sky.
Only every few years is solar activity so strong that these effects can be seen south of the polar regions.
During Tuesday night, the light show could also be enjoyed in Germany, Austria, and parts of the UK.
