Something Mysterious Lit Up the Russian Sky — and No One Knows Exactly What It Was

Video posted online shows something light up — possibly explode — over Russia's Sverdlovsk region Friday — but no one is exactly certain about what it is.

The incredible dashcam footage shows the sky first glow red before morphing into a bright yellow light.

The images appear to be reminiscent of the Chelyabinsk meteors that fell from the sky in 2013, prompting most individuals to point to the stars for an answer.

However, one expert disagreed.

"My guess this is something originating on Earth," Dr. Marco Langbroek of the Dutch Meteor Society said, according to a meteor-watching blog. "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 Russian news outlet suggested there might be a chemical plant nearby that may have also been the cause of the glow.

At the time of publication, however, the entire incident remained a mystery, igniting passionate discussions online about the potential cause.
