Planet Made Completely Of Ice Is On Fire
- Year Discovered: 2013
- Location: Gliese 436 Star System, Leo Constellation
Have you ever put your hand under super-hot water and your hand originally was cold until you experienced the burn? What about a warm feeling before touching something bitterly cold? This is not just something humans experience, as it can (sort of) happen to planets too. The Gliese 436b planet is certainly a paradox for astronomers. This exoplanet is almost exclusively made from ice. Yet somehow, it is also on fire.
On the surface of the planet, the temperature reaches 822 degrees Fahrenheit (439 degrees Celsius). In spite of this, the planet maintains its icy landscape, remaining completely frozen. How does it accomplish this? At first, scientists did not know but eventually, they found that the immense gravitational force exerted by the planet’s core was the cause. This force makes ice much denser, allowing it to handle high levels of heat. It even compresses water vapor that might normally evaporate.
