Exoplanet Study Discovers Water

In this months edition of Nature Astronomy, scientists recently discovered a new planet K2-18b. K2-18b is an exoplanet, meaning it resides in another solar system. It is about 110 light-years away and about 8 times the size of our planet. 

What’s unique about K2-18b unlike other exoplanets, is that it lives in a habitual zone, meaning its in the prime distance from it’s star to be able to sustain life. Recently the Hubble Space Telescope revealed that the atmosphere on K2-18b contains water molecules in the form of cloud vapor, a good indication of it being able to support life.

No one knows what K2-18b looks like, but experts speculate that it could be similar in style to that of our own planet but with a different molecule composition. This will all be re-verified when the James Webb Space Telescope launches in 2021, which will have better and more accurate means of verifying such discoveries.
