A mysterious shiny spiral was spotted in the sky above Mauna Kea in Hawaii; it was captured by the Subaru Telescope on Sunday.
Despite the very unusual scenery it created, the explanation behind the spiral may be quite prosaic. Apparently, it was a dying SpaceX rocket that generated the weird trail, which looked like a flying whirlpool in the sky.
The theory might be reasonable, particularly in light of the fact that the spiral was spotted in the sky shortly after a California-based Falcon 9 rocket launched a spy satellite into orbit. The launch was carried out from the Vandenberg Space Force Base in California.
