Uranus emits more internal heat than previously known

New findings show Uranus emits internal heat, challenging previous data from Voyager 2.

Uranus reveals unexpected internal heat prompting new mission discussions

Scientists have discovered that Uranus emits 12.5% more internal heat than it receives from the sun. This finding contradicts the observations made by NASA's Voyager 2 nearly forty years ago, which suggested Uranus had minimal internal heat. Led by Xinyue Yang of the University of Houston, researchers analyzed decades of data to reveal this unexpected heat emission. These results suggest new insights into Uranus' internal structure and evolutionary history, challenging previous assumptions about the planet. The findings may support future missions to Uranus, such as the high-priority Uranus Orbiter and Probe, which has been flagged by the National Academy of Sciences despite uncertainties in funding and political support.

The implications of Uranus' newfound internal heat are significant. This research could reshape our understanding of not only Uranus but also other giant planets in our solar system. As scientists work to translate these findings into actionable plans for exploration, the interplay of politics and budget constraints adds another layer of complexity. The urgency to push forward with missions to Uranus not only lies in advancing planetary science but also in providing valuable perspectives on Earth's climate challenges.
