Found this on Spaceweather site. I know Dave will get it. For you others, I'm referencing the "PETUNIAS FALL FROM THE EDGE OF SPACE" bit.

SOunds a bit HHGTTG...

That was an exceedingly cool article, dampened only very slightly by the fact that the Infinite Improbability Drive® made the petunias and the whale out of nuclear missiles, not over Earth, but over the planet of Magrathea. Still, it was a great homage to the Father of Arthur Dent, the Vogons, and Marvin, the Paranoid Android.

Plus, it was cool science.
