NASA's Juno spacecraft was launched on August 5, 2011 and arrived at Jupiter on July 4, 2016. Named after the "cloud piercing" wife of Jupiter, its mission is to investigate the atmosphere of Jupiter to measure the composition, particularly the amount of water, and to observe Jupiter's magnetic and gravitational fields. The information we are gaining from Juno will help us better understand the origin and evolution of Jupiter, which will also help us understand the formation of giant planets. I will discuss the layout of the solar system and what we know about Jupiter, theories of planet formation, questions the Juno mission strives to answer, and the latest results from Juno.
