Astronomers picked up some interesting tid bits recently. Apparently old tv shows hurled into space on the VHF frequencies, hit something and bounced back, returning to earth. They attempted to track down the objects that intercepted the shows but even the old Hubble telescope couldn't manage it.
In the wave? Dr. Who!
I don't know if I believe any of this, 2009 was a crazy time and the planet consumed by madness, but here ya go!
