In this exciting cosmic adventure, Finny, a young fish, travels through space and time while a supercomputer, Mr. Guru, educates the time traveler about the wonders of the universe. After witnessing the Big Bang, Finny sails through space and enters a formation of luminous, colorful clouds—a nebula, the nursery of the stars.

 Inside the nebula, Finny encounters Mr. Megha using dust and gas to build stars. Megha gives Finny a tour of the nebula, explaining how stars are born. Finny learns how a massive star ends its life in a supernova explosion, spewing elements into space. Curious, the youthful explorer ventures out of his spaceship to catch some gold, and experiences the effects of the fiery burst of the supernova.

Finny learns about the techniques that scientists use to measure distances in light years, and hears stories from mythology behind the names of stars and galaxies. The adventure continues…
