Scientists analysing data from the Cassini-Huygens mission have uncovered a significant structural surprise in Saturn’s protective magnetic bubble.
Researchers say this discovery confirms that giant planets operate under a different magnetospheric regime from the Earth’s.
The study in Nature Communications includes Dr Licia Ray and Dr Sarah Badman from Lancaster University with Dr Chris Arridge, formerly of Lancaster.
Saturn's magnetic shield is asymmetrical compared to Earth’s, suggests a new study involving University College London (UCL) researchers, and this is likely a result of its fast rotation coupled with the heavy material it pulls around it.
