Recently, researchers allegedly found signs of life on an exoplanet. New research data now makes this seem very unlikely.

A paper published in 2023 spurred discussion about whether life exists on an exoplanet named K2-18b. Two years later, the puzzle continues — and some scientists are expressing doubt.

Additionally, K2-18b would need to have a rocky surface in order for liquid water to sit on it. "It might have a rocky surface, but it is more likely a giant ball of liquid and gas, like Neptune ...

"It confirms K2-18 b to be our best chance to study a potential habitable environment beyond the solar system at the present time." ...

Recently, a group of scientists claimed they found possible signs of life on a planet called K2-18b. The news made headlines. Researchers said they'd detected sulphur-based gases that, on Earth ...

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.
