How Do Planets Form? Juno's Jupiter Mission Aims to Find Out

A NASA spacecraft is about to start unlocking the many secrets of giant, mysterious Jupiter. The Juno probe is scheduled to enter orbit around Jupiter on Monday (July 4), after a nearly five-year trek through deep space. Juno will then study Jupiter intensively over the next year and a half, peering deep inside the gas giant to help researchers better understand how it formed and evolved — information that should shed light on planet-formation processes in general.
