Scientists have found strong signs of possible life on exoplanet K2-18b, a "Hycean world," suggesting new avenues in the search for alien life.

Astronomers have detected possible chemical signs of life on a faraway planet. But they caution much more work is needed to confirm their findings.

K2-18 b is 8.6 times as massive as Earth and with a diameter of about 2.6 times as large as our planet. It orbits in the ...

The findings suggest that there are many more targets of opportunity for locating potentially habitable worlds across our ...

Scientists using the James Webb Space Telescope have obtained what they call the strongest signs yet of possible life beyond ...

A new discovery could represent the most concrete evidence of alien life to-date, but scientists caution that further studies are needed.

U.S. team of researchers detected signs of two chemicals in the planet's atmosphere long considered to be "biosignatures" indicating extraterrestrial life.

Further studies are needed to determine whether K2-18b, which orbits a star 120 light-years away, is inhabited, or even ...
