The green fireball buzzing over the Russian hi-tech "scientific city" in Siberia has prompted the claim that Vladimir Putin could develop space weapons.
Bright flash and stripes were seen by stunning motorists near the research city of Akademgorodok near Novosibirsk, Russia.
Research institutes in the area are called Vladimir Putin's "secret weapon" in a global arms race.
Only six kilometers away is Koltsovo, the home of the secret Institute Vector – the repository of the planet's most dangerous diseases and viruses, including smallpox, Ebola and Marburg.
The images were captured on dash camera in the morning darkness.
Some observers claimed it was an "extraterrestrial attack" or a meteor exploding in the sky.
Other suggestions were Russian testing of "Extremely Advanced Weapons" or "UFOs Ready to Invade Ukraine".
The State Russian media admitted that astronomers were "a little confused" by the view.
Ilya Orlov, Deputy Director of the Great Novosibir Planetarium, called her a "beautiful phenomenon," but she could not be sure what caused it.
He said, "Most likely, it's a flash of bolides, that is, the fall of a bright meteor with lightning."
If so, it's unusual, he said.
He said, "Even more surprising is that the meteor showers are not active now.
"It may be either the tail of a meteoric sleep or a lonely meteor.
"We have to find out."
No traces of cosmic stone were found on snowy soil, it was reported.
Explosions were also not reported.
It is unlikely that missiles or missile tests were launched at the time they appeared early Tuesday.
Akademgorodok was founded in 1957 by the Kremlin as a base for Soviet scientists in Siberia – far from the mysterious eyes of the West.
Today it is home to many of Russia's leading researchers and academics, who specialize in all fields of science, including military and space development.

In recent years, Vector has been involved in efforts to find medicines and antidotes against murders such as bubonic infection, anthrax, hepatitis B, HIV, and cancer.
The research center has one of two sources of pox in the world – the second is in the US – according to an international agreement.
It's not the first time they fear Russian secret weapons programs, some claim to develop robot tanks and a new generation of stealth bombers that have overtaken the West.
