The sun's environment in interstellar space the heliosphere is essentially a bubble that encompasses the entire solar system and has a diameter about 100 times the distance from the Earth to the sun. This region, in which the solar wind dominates before it smashes into the surrounding galactic gas and dust, was supposed to look something like the shape of a comet: a region pushed inward on one side and streaming outward on the other. But a new NASA orbiting observatory designed to study this vast zone found something completely different.

Bursting the sun's bubble
"Invisible Pink Unicorns are beings of great spiritual power. We know this because they are capable of being invisible and pink at the same time. Like all religions, the Faith of the Invisible Pink Unicorns is based upon both logic and faith. We have faith that they are pink; we logically know that they are invisible because we can't see them."
