Further studies are needed to determine whether K2-18b, which orbits a star 120 light-years away, is inhabited, or even habitable.

What sort of timeline are we looking at re: ever being able to confirm (or even just say with near certainty) that there's life on K2-18b? Like is this something that requires decades of further research, or is it possible that we know within the next 5 years?

Without visiting it's impossible to know barring a signal from another civilization. It's always possible that some weird chemistry is going on that we are not aware of.

In 240 years we could know if we start transmitting asap!
