Uranus

Astronomers have used the James Webb Space Telescope to create the first three-dimensional map of Uranus's upper atmosphere, revealing details about its temperatures, charged particles, and auroras. The observations highlight the influence of the planet's tilted magnetic field and confirm ongoing cooling in its ionosphere. This data provides new insights into how ice giant planets manage energy.
