Astronomy (and geology to some extent) include some study of the creation of the world and cosmos. This is also a field in which God's hand is frequently invoked. Thus, to find that there is no such evidence of divine interaction in these fields is somewhat more important to the question of God's existence than his absence from your pipes.There are no gods in plumbing or geology either as I said before.
Are people supposed to be looking for gods in these places?
