New observations fail to confirm signs of life in the atmosphere of the distant planet K2-18b. They also raise questions ...

The planet in question, K2-18b, was discovered in 2015 by NASA's Kepler mission, which revealed that planets outside our solar system are so common that they outnumber stars.

K2-18b, scientists say, could be in an excellent location for alien life to emerge—having perfect conditions for surface water, a fundamental ingredient for life, to exist.

The 'super-Earth' K2-18b sits within the habitable zone of its host star, meaning it is not too hot or too cold for liquid water to exist. This raises the possibility that it could support alien life.
