The Juno spacecraft orbits Jupiter in this artist's concept. By mapping the giant planet's magnetic and gravitational fields, Juno has given scientists a better look at conditions inside Jupiter. Juno arrived in July 2016 and is expected to keep operating for several more years. The craft is temporarily out of touch because Jupiter is aligning behind the Sun as seen from Earth, so its radiation interferes with communcations with Juno. [NASA/JPL]
