Doubts mount further over signs of alien life on K2-18b: 'This is evidence of the scientific process at work'

Independent analysis of data casts doubt on validity of "strongest evidence yet" of life beyond solar system.

Team of Cambridge-led astronomers announced they'd found sulfur-based gases in an alien planet's atmosphere.

The data is likely too noisy or the signal too weak to draw definitive conclusions.

The signals might be absent, or they could be present but currently undetectable.

More observations are needed to resolve the uncertainty, said Schwieterman .

"If the ultimate result of this story is that the public is more circumspect about future claims of life detection, that's not a terrible thing," he said.
