When I was somewhere between 9 and 11, I checked out a book from a library in northern California that was a picture book that came with a cassette tape. It was a science fiction story about a kid that went in a robot spaceship that traveled the universe and back. Along their journey they visited multiple space phenomenons, including visiting Alpha Centauri, almost getting sucked into a black hole, and searching for life in deep space by looking for radio waves/signals that may be nearby. They actually found a radio signal, but when they tuned in, it turned out that the radio broadcast of “Howdy Doody” from 50 years or so prior had made it out that far and that was what they were picking up. The whole story was geared toward education of different types of stars, galaxies, space phenomenon, etc., for a child, and most of this “tour” through space was narrated by the robot/spaceship that the child was a passenger in. It was VERY entertaining, with great pictures and I’m surprised that I couldn’t find it with a quick google search!
