A mysterious silent flash which lit up the Russian night sky has baffled people and sparked theories of extraterrestrial activity. Experts have said the blue and white burst of light, which illuminated Stavropol in southern Russia, is not natural. The strange glow was not accompanied by any sound, according to witnesses, and made the city’s street lights briefly go out.
It was also said to have caused bulbs inside homes to flicker, according to RT.com. ‘I was very frightened by what I saw, I was already in bed,’ said one woman, according to the website.’It looked as if something very bright lit up my ceiling.’ The flash was captured on a vehicle dashboard camera at around 12.39am on Monday morning.
