Apparently brown dwarf stars leave large amounts of helium in their wake. Also,
Space is not a good conductor of solar bursts but helium is.

A large amount of helium has gathered between two planets. It is projected that on Nov 25 the Sun will basically short across to this helium and transfer so much energy that it will glow blue for 10 days until restored.

I know this sounds nuts but would account for the fake suns being tested.

This story is reported to come from nasa but?
