New discovery is ‘strongest evidence yet’ of alien life on distant planet

• Scientists have found potential signs of life on K2-18b, a planet 120 light-years from Earth.
• The study, published in the Astrophysical Journal Letters, identified a molecule in K2-18b's atmosphere associated with living organisms on Earth.
• Researchers suggest K2-18b may have a hydrogen-rich atmosphere and a deep ocean, potentially teeming with life.
• While the findings are significant, experts caution against premature conclusions, emphasizing the need for further investigation.
• The presence of the molecules could indicate a new chemical process or the first signs of extraterrestrial biological activity.
