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

Scientists have found new but tentative evidence that a faraway world orbiting another star may be home to life. A Cambridge team studying the atmosphere of a planet called K2-18b has detected signs of molecules which on Earth are only produced by simple organisms.

Astronomers have made a detection suggesting biosignatures, or signs of biological activity, on an exoplanet located 124 light-years away. But experts are skeptical.
