Astronomers have unraveled the mystery of Uranus: the planet has its own internal heat.

Uranus has internal heat - this is the discovery of an international team of astronomers who found that the planet emits more heat than it receives from the Sun. This helps resolve an old astronomical mystery that has puzzled scientists since NASA's Voyager 2 expedition in 1986.

To achieve this result, scientists conducted decades of observations, data analysis, and computer modeling. They suggest that this heat emission is linked to Uranus' unique structure or evolutionary history. Compared to other gas giants, Uranus remains 'colder', but the presence of an internal energy source is a key distinction.

Scientists believe that this research helps to better understand Uranus and other gas giant planets. The direction for the future is a mission to Uranus to gain further insights into this mysterious planet in our solar system.
