James Webb Telescope Unveils Unexpected Activity Above Jupiter's Great Red Spot

New observations reveal intricate structures and dynamic processes in the planet's upper atmosphere, challenging previous assumptions.

Astronomers discovered dark arcs and bright spots in Jupiter's upper atmosphere using the James Webb Space Telescope.
These features are believed to be caused by powerful atmospheric gravity waves originating from the planet's turbulent lower atmosphere.
The findings contradict earlier predictions that this region would be unremarkable and homogeneous.
Researchers aim to conduct follow-up studies to understand the movement and energy dynamics of these wave patterns.
The discoveries will aid future missions, including ESA's Jupiter Icy Moons Explorer, in exploring Jupiter's environment and its moons.
