New research from NASA's Juno mission reveals that lightning strikes on Jupiter are dramatically more powerful than those on Earth – potentially up to a million times stronger. By analyzing radio and microwave emissions, scientists found the average lightning strength ranged from comparable to Earth's to 100 times more powerful, with the maximum reaching an astonishing one million times greater. This difference is attributed to Jupiter's hydrogen-rich atmosphere and the greater height of its storms.

Why it matters

This discovery provides valuable insights into convection and heat transfer within gas giants, reinforcing Jupiter's reputation as a planet with the most extreme weather in our solar system. Understanding these processes is crucial for comprehending the dynamics of other gas giants, both within our solar system and beyond.

The details

A team led by Michael Wong from the University of California, Berkeley, employed a novel approach to determine the actual strength of Jupiter's lightning strikes. Instead of relying solely on visual data, they analyzed radio and microwave emissions from the Juno spacecraft's instruments. This breakthrough was aided by a period of reduced storm activity in Jupiter's north equatorial belt between 2021 and 2022, allowing the researchers to focus on a single, large 'stealth superstorm' system.

  • The Juno mission has been observing Jupiter since 2016.
  • The research was published in the journal AGU Advances in 2026.

What they’re saying

“Is the key difference the hydrogen versus nitrogen atmosphere, or is it because Jupiter's storms are so tall that there's a greater distance for the charge to build up?”

— Michael Wong, Researcher, University of California, Berkeley

What’s next

Researchers plan to continue studying Jupiter's atmospheric dynamics and weather patterns using data from the Juno mission, with the goal of further understanding the processes that drive the planet's extreme conditions.

The takeaway

This research provides groundbreaking insights into the extreme weather conditions of Jupiter, the largest planet in our solar system. By unlocking the secrets of Jupiter's powerful lightning, scientists are gaining a deeper understanding of the unique atmospheric composition and convection processes that shape the dynamics of gas giants, both within our solar system and beyond.
