Where do I find this stuff?

I can't say I'd ever heard of this, but according to an article in the Observer that says studies are being done on "...one of the strangest incidents in recent meteorological history. On 25 July, 2001, blood-red rain fell over the Kerala district of western India.". the article states that one researcher believes the redness is caused by alien bacteria from a comet. Perhaps our first evidence of alien life.

Perhaps this explains the Peter Gabriel song.
