A blue spiral that looked like a galaxy - or perhaps a portal to another dimension - was pictured in the skies above the US state of Alaska over the weekend. The reason behind its appearance is, however, fairly mundane.

 

Already enjoying a light show put on by the aurora borealis, skywatchers were shocked to see the spiral appear on Saturday for a few minutes.

 

While it looked like something out of Philip Pullman's His Dark Materials series, where the protagonists move between worlds in a portal opened amid the Northern Lights, the spiral was in fact caused by frozen rocket fuel.

 

A SpaceX rocket had launched from California around three hours before the spiral appeared. Rockets sometimes jettison their remaining fuel, explained space physicist Don Hampton, a research associate professor at the University of Alaska Fairbanks Geophysical Institute.

 

“When they do that at high altitudes, that fuel turns into ice,” he said. “And if it happens to be in the sunlight, when you’re in the darkness on the ground, you can see it as a sort of big cloud, and sometimes it’s swirly”.
