St. Thomas says
1. Whole World will be renewed. But Heavens are more noble part of the World. So therefore, we conclude yes
2. From Scripture: Rom 8:19. Creation awaits the glory of the Saints. Therefore Something will need to increase to this creation.
1. Purpose for this increase is that God may be seen in a way by man through a manifest physical sign.
2. The appearance and beauty of creatures principally manifests the wisdom of their creator, so this would be fitting but greater brightness.
3. Therefore God will improve the beauty of the heavenly bodies, stars etc. by increasing their brightness in quantity. The heavenly bodies which have not been affected by man's sins will not need to be purified by the fire at the end of the world. Only those where man has tainted in some way.
