• •Jupiter's auroras are bigger and stranger than those on Earth.
• •Scientists have discovered a new type of plasma wave in Jupiter's auroras.
• •The discovery could help scientists understand auroras on other worlds and how magnetic fields shield planets from radiation.
• •The research is based on data from NASA's Juno spacecraft.

Scientists have discovered a previously unknown type of plasma wave in Jupiter's auroras, thanks to data from the Juno spacecraft. This finding could help scientists better understand auroras on other worlds and how magnetic fields protect planets from radiation. Jupiter's auroras are more powerful and chaotic than Earth's, and the research suggests these conditions may be common on other planets and stars. The team continues to analyze Juno's data to learn more about plasma behavior and planetary protection.
