It then seems to transform into a swirling object before disappearing.
Alien enthusiast Blake Cousins uploaded some of the best footage to his YouTube channel thirdphaseofmoon yesterday (September 27).
“Is this a rocket spiralling out of control or is this a portal opening up in the night sky?” he asked in the clip.
“If anybody asks me to describe an UFO, this is exactly how I would have pictured it,” one wrote.
Another added: “I was horrified, and all my friends saw it, nobody knew what it was.”
Russian officials have since confirmed the sighting was in fact an RS-12M ICBM missile, tested amid growing fears of WW3 breaking out with North Korea.
It was launched from the Kapustin Yar testing range in southern Russia and hit its target in a remote area of Kazakhstan with “desired” accuracy.
