Scientists left baffled as mysterious columns of coloured light appear in the night skies

These stunning images show mysterious columns of light streaming into the sky above the town of Sigulda in Latvia at the end of last month.

Scientists at the website spaceweather.com said: 'Truhin’s pillars are not the ordinary kind. Even eading experts in atmospheric optics can’t quite figure them out

'These pillars are mysterious. They have unexplained curved tops and even curved arcs coming from their base. 

'Arcs in rare displays like these could be from column crystals to give parts of tangent arcs, others could be the enigmatic Moilanan arc or even the recently discovered reflected Parry arc.
