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 ...

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.

K2-18b is an exoplanet that is 110 light-years from Earth. It was found in 2015 with NASA's Kepler space telescope and is of interest because of its position within its solar system.
