Slippy makes special safety goggles for everyone so they can watch an eclipse. When Ella insists on going to watch a binary star supernova, Slippy opts out and heads off on his own.  Gem and Ilo meet up with Ella at the supernova. They've come to watch too. She listens to the cousins bicker and realizes that the supernova isn’t as much fun without her friends. She decides to join Slippy.  She arrives just in time to help him escape a cloud of crashing meteoroids. They both realize that being stubborn is no fun!

The year is 3021. The place is the Milky Way, where eight-year-old Ella gleefully heads out with her friends on exciting adventures of discovery. At only eight, she already knows quite a bit about space... but there is always more to explore!
