Did you know that the image of the moon we see through a telescope is actually from 1.3 seconds in the past? This space science picture book takes complex concepts like space, the speed of light, and time travel and makes them easy and fun for children to understand. From the basic fact that we need light to see things, to the principles of how telescopes gather light from distant objects, and the relationship between distance and the speed of light, the book offers a wealth of scientific knowledge. Join T. Rex, the dinosaur on a pair of socks, for a fun and educational journey through time!
