Mysterious Explosion Over Russian Sky Caught On Camera

What could possibly have caused this brilliant, mysterious explosion over Russia?

A new video shows footage captured most likely by a dashcam of a car on a Russian highway and has everyone who witnessed it in awe.

It shows an apparent explosion lighting the sky in a red-orange hue over Russia's Sverdlovsk region. No one knows what the mysterious explosion is, though it reminds one of the enormous fireballs that fell over Chelyabinsk in early 2013, triggering a shock wave that smashed windows, damaged buildings and injured more than 1,000 people.

There is no knowing what caused the explosion but at least one expert believes it may not be celestial in origin. "I doubt this one is a meteor," says Marco Langbroek of the Dutch Meteor Society. "To me, it looks like a fire or series of small explosions and subsequent large explosion or flash fire reflecting on a cloud deck."

A local news site suspects  the explosion was from an old chemical plant outside the nearby town of Rezh.
