1. A new radar study concluded that the core of Mercury is at least partially molten. The finding settled a debate and provided insight about the creation of solar planets. (main conclusion)
Debate 1 solid: Mercury seems obviously to have a molten core. However, the fact that the heat left over from the planet's formation and Mercury's small size suggested to astronomers that the core was solid.
2. Debate 2 molten: Mariner 10 spacecraft found the magnetic field of mercury. Like Earth, Mercury should have a liquid core to generate the magnetic field. However, it is entirely possible that the magnetic field is caused by the remnant in the crust.
3. New radar research by JLM suggested that: the bounced radio waves signified the small variations in Mercury's spin, the variation itself told that Mercury's spin is impacted by the sun's gravity. The impact is bigger if the core is at least partially liquid.
4. Indeed, the impact is more significant than thought to be. Therefore, the outer core of Mercury must be liquid. How come? Because of sulfur infiltrated the planet's iron core and lowered its temperature. The sulfur might be grabbed beyond Mercury's immediate surroundings, as other planets did.
The author presents a new study that settled a scientific debate and explains the possible cause of the phenomena. |
