The James Webb Space Telescope was used by scientists to examine K2-18 b, a planet that has been found to contain carbon-bearing molecules such as methane and carbon dioxide. The space is 8.6 times larger than Earth and recent research suggests that it may have water oceans on its surface and containing hydrogen.
The cool dwarf star K2-18 is located in the “goldilocks zone” of the constellation Leo, orbiting the planet K2, which has enough light to produce liquid water without being boiled into vapour. Some scientists have proposed that this hypothetical planet is called a “Hycean planet,” and it is believed to be hot and gassed with ice and hydrogen gas within its atmosphere.
NASA has announced that the research results will be published in the journal Astrophysical Journal Letters.
