Something strange is happening inside Saturn
Researchers are also looking at Uranus' rings to see if they can discern anything about the inside of that planet — and there are many other rings to consider out in the solar system. But for now, Saturn offers the best glimpse into the depths of a gas giant, which can be compared and contrasted with the distant planets seen around other stars. Exoplanet researchers like Jonathan Fortney at University of California, Santa Cruz, are eager for anything that will pierce the veil of the gas giants. In fact, he said, one of his graduate students is waiting until Cassini plunges into Saturn, in 2017, to combine the new gravitational data with kronoseismology to get an even more detailed picture.
