The exoplanet, called K2-18 b, could be a Hycean planet – meaning it has a hydrogen-rich atmosphere and an ocean.
, which means its distance from a star may allow water to exist on its surface. These zones are also known as"Goldilocks zones," taking their name from the old children's story because conditions are"just right" for life.
The DMS on the planet also leads researchers to believe there could be life on the planet, since DMS in Earth's atmosphere is, a marine algae that provides food to sea creatures and is created by sunlight. Planets like K2-12 b are still"poorly understood," NASA says. However, some astronomers believe they could be a promising place to search for life.
