According to the local media in Alaska, From the late night of April 14 to the early morning of April 15 local time, a "mysterious spiral light" appeared over Alaska, Many Alaskans also witnessed this strange spiral light moving over the state.
After the photos of the scene came out, some netizens said that it looked very much like the portal of space-time transmission, and also like an alien spaceship.
According to the photographer's description, a bright light suddenly appeared on the northern horizon. As it approached, the light quickly showed a spiral shape, and then the blue and white spiral seemed to start moving rapidly.
This photo has caused heated discussion on the Internet, and it looks very mysterious.
It is worth noting that science is behind all this.
Hampton, an associate professor at the Geophysical Research Institute of the University of Alaska Fairbanks, said that the spiral light seemed to come from the exhaust gas of the Falcon 9 rocket engine launched by SpaceX in California.
According to domestic bloggers, after the rocket completes its mission, before falling back into the atmosphere, For the sake of safety, the residual fuel, high-pressure gas and residual electricity of the battery should be drained, which is called "passivation".
When the gas is discharged, it will cause the arrow body to rotate. The arrow body will rotate as it rotates, and the arrow body will rotate as it rows, thus forming this "big display".
The mysterious spiral light appeared just at the time when the second stage of Falcon 9 rocket passivated and emptied the propellant before reentering the waters north of New Zealand.
