- The Scientists have discovered a new class of molten liquid exoplanets using the James Webb Space Telescope.
- These planets are neither rocky planets nor water worlds, but are covered with vast global oceans of molten magma.
- The planet L 98-59 d is an example, located about 35 light-years from Earth, with a very high surface temperature of around 1,900°C.
- It has a dense atmosphere rich in hydrogen sulphide gas, creating a strong greenhouse effect and extreme conditions.
- This discovery introduces a third category of planets dominated by molten silicate material.
