Part of the problem when it comes to spaceship detection is that they
aren't relatively cool planets - in a world with realistic physics, a
ship with enough power plant to run a space-drive and weapons and so on
is seriously glowing, and will be obvious to anyone with an IR detector
at several AU range. (Ask Ken Burnside about this...)
