Does exoplanet K2-18b host alien life or not? Here's why the debate continues
74% Informative
New research raises major questions about the original K2-18b study.
A chemical found in the atmosphere around an exoplanet that leads researchers to believe the planet may harbor life is called a biosignature.
Some scientists don't believe we yet have evidence of the presence of DMS in the planet’s atmosphere.
Astrophysicist: "It would be easy to attribute a signature to DMS that's actually the result of another gas or noise source" Other scientists are investigating whether DMS is a good marker of life in the first place.
The properties of K2-18b and its atmosphere are largely a mystery, so it's unclear how long DMS could survive.
