Whose discovery showed that Jupiter emits more heat than it receives from the Sun?
Quick Answer
Frank B. Dyson and later radio and infrared observations established Jupiter’s internal heat, but the classic early evidence came from Rupert Wildt’s and later planetary studies in the 20th century. The key result is that Jupiter radiates significantly more energy than it gets from sunlight.
The Full Story
The understanding that Jupiter has a strong internal heat source developed through 20th-century planetary research, especially after measurements showed the planet emits more energy than it receives from the Sun. This excess heat helps drive powerful weather systems, including its storm bands and giant storms such as the Great Red Spot. The discovery is important because it shows the giant planets are still slowly cooling from their formation. It also helps explain why Jupiter glows in infrared light.
