The James Webb Space Telescope has discovered TOI-270 d, a distant exoplanet that may be a "Waterworld with a boiling ocean." Scientists used JWST's tools to study its atmospheric makeup, revealing it as a candidate Hycean world, adding to the ongoing exploration of space.
The James Webb Space Telescope has detected an organic molecule, along with methane and carbon dioxide, in the atmosphere of exoplanet K2-18 b, suggesting the possibility of life in its vast global ocean. The planet, located 120 light-years away in the constellation Leo, is believed to be a Hycean world, a type of potentially habitable planet with hydrogen-rich atmospheres and world-spanning oceans. Further observations are needed to confirm the presence of life and determine if the planet's radiation has made its ocean too hot to sustain life as we know it.
The Webb Space Telescope has detected possible molecular signals on the exoplanet K2-18 b, suggesting it may be a Hycean world covered in a global ocean with a hydrogen atmosphere. The telescope observed signs of water vapor on the exoplanet, which lies in its star's habitable zone. The presence of carbon-bearing molecules indicates the possibility of a water ocean beneath the hydrogen atmosphere. Additionally, the telescope detected a potential detection of dimethyl sulfide, a molecule produced on Earth by living organisms. Further observations will be conducted to confirm the presence of dimethyl sulfide and better understand the nature of this water world.
The James Webb Space Telescope (JWST) has detected carbon-based molecules in the atmosphere of exoplanet K2-18 b, a suspected ocean world located 120 light-years away. The planet, which is larger than Earth and smaller than Neptune, is considered a potential habitat for life due to its size and location in the habitable zone. The presence of carbon dioxide and methane, along with a possible detection of dimethyl sulfide, suggests the existence of a water ocean under a hydrogen-rich atmosphere. Further observations with the JWST will help confirm these findings and provide more insight into the environmental conditions of such exoplanets.
