It’s easy to assume that the brightest stars in the night sky are the closest to Earth—but in astronomy, appearances can be deceiving. Measuring distance has long been one of the field’s greatest challenges, yet astronomers have assembled a remarkable “distance ladder” that extends from our cosmic backyard to the very edge of the observable Universe. In this class, we’ll explore how astronomers measure distance, from bouncing lasers off the Moon to using stars and galaxies to probe the largest scales of the cosmos.
