“I went out to smoke a cigarette and thought it was the end of the world,” said local, Vasily Zubkov, who witnessed the strange phenomenon in the sky. Bizarre and unexplained lights have been spotted in the sky over Siberia by several local Russian residents.

The light has been described as an expanding orb, or a large, bright round ball that grows in size and eventually dissipates. The spectacle could be seen for hundreds of miles.

The strange display was handily captured on film as several photographers were out taking shots of the Northern Lights. Siberian photographer, Sergey Anisimov, described his reaction: “My first thought was about the most powerful searchlight, but the speed of changing everything around changed the idea of what was happening.”

Alexey Yakovlev, another photographer 520 miles away, found comfort in the fact that others were also witnessing the multicolored light show. He claimed that as the ball of light expanded and that it became quite “scary”, and was very glad to know he wasn’t hallucinating.

“It’s good that I was not alone. A group of people cannot hallucinate.”

Many witnesses speculated about an alien invasion. Social media in the area was flooded with theories about the cause of the spectacle, which ranged from a tear in the time space continuum to a UFO landing.

Nigel Watson, author of The UFO Manual, talked to Mail Online about the strange lights. He agreed that it “looks amazing and it is not surprising the sight of it caused witnesses to think of aliens and the opening of a portal to another dimension.”
