"James Webb Space Telescope reveals exoplanet's oceanic surface"

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.

Early Discovery: Carbon-Based Molecules Emerge Shortly After Big Bang

The James Webb Space Telescope (JWST) has discovered evidence of carbon-based molecules and dust existing just a billion years after the Big Bang, challenging previous assumptions about the early Universe. The dust observed in the early galaxies studied by JWST appears to consist of graphite or diamond-like grains, similar to those observed in later cosmic history. Astronomers speculate that these diamond-like grains may have come from debris ejected in supernova explosions or from Wolf-Rayet stars, which are known to be efficient dust producers. The discovery provides insights into the earliest stellar populations and the formation of dust in the Universe.
