Potential Signs of Life Detected on 'Hycean' Exoplanet K2-18b
Summary
Astronomers have detected potential biosignatures on the 'Hycean' exoplanet K2-18b, which may have a liquid ocean and hydrogen-rich atmosphere, raising the exciting possibility of extraterrestrial life, though further research is needed for confirmation.
Key Points
- Astronomers have detected chemicals dimethyl sulfide and dimethyl disulfide in the atmosphere of exoplanet K2-18b, which could be potential biosignatures indicating the presence of life.
- K2-18b is an exoplanet in the habitable zone of its star, and previous studies suggested it could be a 'Hycean' planet with a liquid ocean and hydrogen-rich atmosphere.
- While the detection is promising, the team remains cautious and further research is needed to confirm if the chemicals can be produced non-biologically at the observed levels.
