Radiosynthetic Geiger

From publisher blurb: Something is occluding starlight as it moves across the star field. Bright stars dim before the object itself passes in front of it, as the atmosphere of the object slowly blocks their light. The stars brighten after the object itself, and then its atmosphere passes by. From space at a distance, Geiger is dark due to the lack of a nearby star. Three bright orange-yellow dots pinpoint volcanic activity on the surface of the dark land. One bright red dot pinpoints volcanic activity under the sea.
