That exoplanet is 124 light-years away in the Leo constellation. It's described as much larger than Earth but smaller than Neptune and orbiting a red dwarf star in what is known as the "habitable zone" – considered the most promising location to find life-supporting planets.

A new study suggests we could be a step closer to figuring out if alien life is out there, trillions of miles away from Earth. It’s based on observations recorded by the James Webb Space Telescope of an exoplanet called K2-18 b.

The discovery was made on a massive exoplanet known as K2-18b that for years has captivated scientists searching for life outside of Earth.
