NASA discovers Jupiter’s invisible shield is more complex than Earth’s

NASA’s Juno spacecraft has discovered that Jupiter uses a surprisingly complex system of powerful plasma waves and multiple shock regions to defend against the solar wind. The findings reveal major differences between Jupiter and Earth and could help scientists understand the enormous shock waves produced by exploding stars.

NASA discovers Jupiter’s invisible shield is more complex than Earth’s Science News from research organizations NASA discovers Jupiter’s invisible shield is more complex than Earth’s NASA’s Juno spacecraft has uncovered Jupiter’s surprisingly complex defense against the solar wind, revealing physics that could help explain the power of exploding stars. The illustration shows how Jupiter employs a series of regions, called shocklets, to engage with the solar wind and slow it down before it meets the planet’s main bow shock. The findings reveal that the solar system’s largest planet relies on a much more complex system of plasma waves and shock regions than Earth does.

Led by scientists at the University of Iowa, the research provides the most detailed observations yet of Jupiter’s bow shock, an invisible boundary where particles from the Sun encounter the planet’s magnetic environment. The discovery reveals important differences in how Jupiter and Earth respond to these incoming particles. Beyond Jupiter, the results could also help scientists understand some of the most powerful events in the universe, including the extreme shock waves associated with exploding stars.

How Jupiter Protects Itself From the Solar Wind The Sun continuously releases a stream of electrically charged particles called the solar wind.
