Remarkable footage shows planets circling a star 133 light-years from Earth

After more than a decade of observations, Northwestern University astrophysicist Jason Wang has constructed an amazing time-lapse video of four planets larger than Jupiter as they revolve around their star, giving viewers a one-of-a-kind glimpse into planetary motion.
Wang, assistant professor of physics and astronomy at Weinberg College of Arts and Sciences, pointed out that it can be difficult to detect planets in a rotating orbit, which is why this video of planetary motion is so striking.
