Astronomers may have found giant alien 'megastructures' orbiting star near the Milky
#45
But we'd see the habitats on the far side of the Sun, since they face us. They would only radiate at 85C, and they would be partially obscured by the ones on this side; if the swarm obscures 20% of the star, then the far side will be 20% obscured as well. We would be looking at a sphere of scattered habitats a couple of AU across, 80% empty space with 20% of that obscured by the habitats on this side of the star. Maybe 16% of the far side of the sphere being visible at any time.

A difficult target to see, but only as difficult as some of the dust clouds that have been observed around various stars. In all probability this is a dust cloud of some sort, but one which is unique to astronomy.
