This is the result of spending a weekend once watching the Discovery Channel. They did a sort of astronomy show marathon. The center is the cosmic soup from which the galaxy was formed. Then particles began to coalesce to form planets. The planet are represented by the various quilt blocks. Earth is the blue planet. Mars & Jupiter orangy/purple, Saturn green and yellow and Venus must, of course, be pink and purple. At the edges of the universe, Uranus.
Then, it was quilted with iridescent thread on a long-arm machine with a special pattern invented just for this quilt that we called - wormholes and stars. This is what happens when science geek and quilting colide.
