However, it doesn't rule out alien megastructures.  Thermal power
satellites for some designs radiate waste heat solar north and south.
If we are on the ecliptic, then we would not see the IR.

It's not likely we found aliens.  But it may be hard to come up with a
naturally anisotropic IR radiation.
