After decades of uncertainty, scientists have discovered the length of a day on the planet Saturn thanks to data from the space vehicle "Cbadini".
In the case of the strange magnetic field and the free surface of the parameters, scientists can not determine the rate of rotation of the planet Saturn. But the vibrations taken by the particles in the rings of the planet provided information on the internal movement of Saturn for the first time and revealed that a day on the ice planet lasted 10 hours, 33 minutes and 38 seconds .
A new study, published in the journal Astrophysical, indicates that ring molecules respond to vibrations inside Saturn, such as the seismic scale, leading to the formation of measurable wave patterns.
"The particles of all the rings can only feel these fluctuations of the gravitational field," said Christopher Mankovic, a graduate student at the University of California at Santa Cruz. At specific locations in the rings, these oscillations capture the molecules of the ring exactly at the right moment in their orbits, in order to generate energy gradually, energy that is consumed in the form of a wave. observable. "
Previous efforts had estimated Saturn at 10 hours, 39 minutes and 23 seconds based on what was known about its magnetic field of radio signals captured by Voyager spacecraft in the 1980s.
However, the magnetic field of Saturn is not a reliable source of information, because it adapts perfectly to the axis of the planets.
The discovery is the latest in the Cbadini data, even after the end of its historical interest in September.
