Join us as we explore what a "light-year" really is and learn how looking deep into space is actually a real-life form of time travel! We will discover how a brilliant astronomer named Henrietta Swan Leavitt used pulsing "heartbeat" stars to measure the impossible, and how a trick called parallax helps scientists measure stars without a giant tape measure.
