New observations fail to confirm signs of life in the atmosphere of the distant planet K2-18b. They also raise questions ...

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 ...

Neptune-sized planet orbiting a red dwarf star 124 light-years away, has been the subject of intense scientific debate.

K2-18b, located 124 light-years from Earth, could be a Hycean world: a potentially habitable planet entirely covered in liquid water with a hydrogen-rich atmosphere, said lead study author Nikku ...

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 ...

The planet in question, K2-18b, was discovered in 2015 by NASA's Kepler mission, which revealed that planets outside our solar system are so common that they outnumber stars.

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.
