This mysterious light spiral showed up in the night sky over many parts of the north on April 16.

Scientific researchers from several universities have said that this phenomenon was caused by unspent rocket fuel attributed to a SpaceX launch, and not to an alien invasion. 😉
If this is indeed the product of a SpaceX rocket, I find it very disturbing that Elon Musk’s company is dumping enough fuel into the atmosphere to be that visible from an estimated distance of three kilometres (1.9 miles).
Although this is an ongoing debate that’s tied up in politics and money, shouldn’t these space/satellite companies be held to the same account on pollutants as others? What do you think?
