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.Taken by designer Aigar Truhins with a standard digital camera, the photographs have prompted excited online discussions among amateur astronomists all over the internet.'My son exclaimed, 'The aliens are coming!'' Truhins was quoted as saying.'It certainly looked that way,' he added.
But experts are agreed there may be a more prosaic explanation - ice crystals in the air. The air above the town was notably cold and filled with suspended ice crystals. It is believed that the columns were formed by those reflecting light from the bright streetlamps and other lights on the ground - beaming it back downwards again.
Skies all over Europe have been filled with such natural phenomena during the cold snap of recent weeks. (Source: Daily Mail)
