Gaius Baltar is not actually an astronomer, it should be noted. Granted, his society makes a point of it becoming more general knowledge than cultures that are more grounded, and it should be said that working as a high level consultant for a fleet of spaceships with no landing in sight for the longest time does familiarise one with the basics. Still, it isn't really a scientific compulsion that sees the man stood here.

And he probably won't be the only one who might look at the skies with regard to his place in the world.

He's dressed down and comfortably for the occasion, having accepted a hot drink. Now and then, he looks around with the manner of someone waiting for someone else, but can otherwise be found drifting, or finding a place to sit, or talking with one of the volunteer speakers.
