Stranger Suns (1989), Cover of Amazing Stories magazine, illustration for a story by George Zebrowski, by Bob Eggleton

The blue sphere is an alien spacecraft in orbit around a triple sun solar system where one sun has become a black hole. A tractor beam from an ancient civilization reaches out in desperation towards the vessel.
