In this study, published in the Journal of Geophysical Research, scientists compared ground-based videos of pulsating auroras--a certain type of aurora that appears as patches of brightness regularly flickering on and off--with satellite measurements of the numbers and energies of electrons raining down towards the surface from inside Earth's magnetic bubble, the magnetosphere
These sources alternate between radio and X-ray pulsar regimes as a result of the interaction between the in-flowing plasma and the outward pressure exerted by their magnetosphere
The encounter was unique within Cassini's mission, as it was the only time the spacecraft has observed Titan in a pristine state, outside the region of space dominated by Saturn's magnetic field, called its magnetosphere
Task orders issued under the PAAC III Bridge contract provide critical support to a wide range of NASA's missions and projects including the James Webb Space Telescope; Magnetosphere
Multi-scale Mission; Joint Polar Satellite System; Geostationary Operational Environmental Satellites; Tracking and Data Relay Satellite; Ice, Cloud and Land Elevation Satellite II/Advanced Topographic Laser Altimeter System; Exobiology on Mars/Mars Organic Molecule Analyzer; Origins Spectral Interpretation Resource Identification Security Regolith Explorer Visible and Infrared Spectrometer; Neutron Star Interior Composition ExploreR; and Deep Space Climate Observatory.
Over the coming months, scientists will analyse the data to unravel the magnetic contributions from other sources, namely the mantle, crust, oceans, ionosphere and magnetosphere
The interaction of solar wind with the magnetosphere
, producing auroras and other phenomena, and magnetohydrodynamic generation are covered next.
The main threat comes when a solar flare disrupts the earth's magnetosphere
The spacecraft will measure Jupiter's polar magnetosphere
and explore the solar system's most powerful auroras - the planet's northern and southern lights - by flying directly through them.
