Another first from NASA’s Juno spacecraft: the detection of Jupiter radio emissions influenced by the moon Ganymede, over a range of about 250 kilometers in the polar region of Jupiter.
NASA’s Juno spacecraft is “hearing whistles” all over the place on Jupiter, a type of natural plasma waves called whistlers that are sometimes associated with atmospheric lightning.
An international armada of orbiting satellites and ground VLF network join forces to form a “magnetosphere-ionosphere observatory” to size up electromagnetic ion cyclotron waves in the magnetosphere.
Omega-band aurora carries fast propagating electric currents in the azimuthal direction, producing geomagnetically induced currents that can cause power outage on the ground beneath.
The first in-situ ion observations from NASA’s Juno spacecraft reveal the surprising, simultaneous presence of cold protons and hot oxygen and sulfur ions in the high-latitude ionosphere of Jupiter.
A Japanese satellite reveals rapid and surprisingly frequent transport of molecular ions from the ionosphere to the magnetosphere, under not only extreme but also moderate geomagnetic conditions.
Primordial solar storm conditions are believed to have significantly enhanced the loss of water and other atmospheric volatiles in Mars’ history.
Highlights from AGU’s joint meeting with the Japan Geophysical Union.
First results from the Juno mission shed new light on Jupiter’s atmosphere, gravity, magnetic field, aurora, history, and more.
Understanding magnetic reconnection is important in the context of Sun-Earth Connection, because of the resulting exchange of mass and energy, and the large amount of energy involved.
