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.
The previous consensus that magnetic dips in the magnetosheath can be attributed to non-propagating mirror waves is now shown to be oversimplified.
When the Earth's and the Sun's magnetic fields meet, they realign in explosive and mysterious reconnections. Data suggest that plasma waves called kinetic Alfvén waves play a key role.
An updated analytical technique gave researchers a new look at ion cyclotron waves in Mars’s extended hydrogen exosphere.
