I don't know if the link below inspired Mike's question, but I provide
it here for synchronicity's sake, given that the former arrived just a
couple of posts after the latter at my end.
* Our Solar System as Seen by Alien Astronomers

"If alien astronomers from a nearby star system pointed their version
of the Hubble Space Telescope at Earth, astronomer Markus Landgraf
believes they would not see our planet but they would find hints of
our presence."
Cheers,
Sean
