James Webb Telescope Reveals Uranus's Mysterious Glow and Cooling Trend

• James Webb Space Telescope (JWST) created a real-time map of Uranus's upper atmosphere, revealing an unprecedented glow.
• A faint glow from molecules thousands of kilometers above the cloud layer was captured, reaching temperatures of 153 degrees Celsius.
• The glow and high temperature are attributed to the interaction of Uranus's tilted magnetic field and solar winds.
• Webb data identified two bright auroral bands near the magnetic poles, similar to Earth's polar lights but affecting the entire atmosphere.
• New research confirms Uranus's upper atmosphere has been continuously cooling since the 1990s, a significant energy loss process.
