Discovery of planet twice as big as Earth emitting gas 'only produced by life' sparks huge excitement among astronomers Astronomers could finally show that alien life does exist on a distant planet following observations today.
Planet K2-18b – which is more than twice as big as Earth and 120 light-years away – sits within the habitable zone of its star in the Leo constellation.
Scientists said last year they thought they'd detected dimethyl sulphide gas in its atmosphere – a compound that is 'only produced by life'.
Now, to confirm the finding, the James Webb Space Telescope will undertake hours of observations of the planet on Friday.

We could not live there as the gravity would kill us.
