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.

Data from the James Webb Space Telescope on exoplanet K2-18b has revealed the "strongest hints yet of biological activity ...

K2-18b is an exoplanet located about 120 light-years from Earth in the constellation Leo. It was discovered in 2015 by NASA’s Kepler mission, which revealed that planets beyond our solar system ...

K2-18b is also smaller than Neptune, making it what astronomers refers to as a "sub-Neptune" planet that, while not present in our solar system, is what NASA says is among "the most common type of ...

K2-18b – more than eight times the mass of Earth and over twice as big – was discovered in 2015. But it was only in 2019 that the presence of water vapour in K2-18b's atmosphere was reported.

An illustration shows what K2-18b could look like based on scientific data. NASA's James Webb Space Telescope has observed K2-18b, an exoplanet 8.6 times as massive as Earth, revealing conditions ...

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.

Professor Giovanna Tinetti, the co-author of the study, told Sky News: "K2-18b might have a boring name, but it is a very exciting planet - it is the first super-Earth in which we can find there ...
