Space pills #5

Okay, I am rather late on this one, but hey, work is a b***h. Another space pill on Juno and its discoveries about Jupiter! A few months ago we published the first-ever solution of the asymmetric zonal gravity field of Jupiter and - guess what? - it is not zero! What does this mean in regular human words? Well, to explain this I should first tell you that the gravity field of a planet is intrinsically related to the distribution of its mass. There is an infinite series of coefficients (the spherical harmonics coefficients) which tell us how the elements distibute in the interior of Jupiter, and one of the objective of Juno is to measure a dozen of these coefficients (the largest and most-important ones). Now, some of them tell us how the mass is distributed in the two hemispheres of Jupiter and we indeed discovered that they are not zero, meaning that there is more mass in one hemisphere than in the other. Practically Jupiter is pear-shaped! Amazing, isn't it?
