Mysterious vortex 'dancing' in the American sky

In the sky of Alaska - USA at dawn on 15 (local time), a "mysterious vortex" suddenly appeared like a space gate.

CBS described the mysterious glowing blue swirl as "dancing in the Alaskan night sky" and looking like a portal or hole in space .

Photographer Todd Salat, who is nicknamed "Aurora Hunter", said that despite many years of taking photos of the aurora, this is the first time he has witnessed such a strange vortex appearing in the sky.

The Institute of Geophysics of the University of Alaska filmed this strange spiral and shared it on social networks. Immediately, the video received many comments with opinions that it was a natural phenomenon, possibly a special form of thunder or a unique light phenomenon.

There are also some people who theorize that it could be due to alien activity or a portal leading to distant places in the universe...

Although the online community has hypothesized its mysterious and strange appearance, this spiral actually has a very normal explanation

Space physicist Don Hampton at the University of Alaska's Fairbanks Geophysical Institute said it was just leftover fuel released from billionaire Elon Musk's SpaceX rocket, which launched from California about 3 hours before the crash. spiral appears.

"Rockets sometimes have fuel that needs to be ejected, and at high altitudes, that fuel turns to ice. If it happens in sunlight and you're in the dark on the ground, you can see it's like a big cloud and sometimes it has a swirling shape" – expert Don Hampton explained.

However, knowing that the mysterious vortex was not a natural phenomenon made photographer Todd Salat regretful.

"The spiral shape is perfect. Very beautiful. I have to say, it's a pity to know that it is exhaust from a spacecraft" - photographer Todd Salat shared - "I'm interested in that mystery because that's what that I didn't know, but when I found out what it was, I noticed my interest had faded a bit."
