   Is There Life on Other Planets? The ultimate goal of NASA's exoplanet program is to find unmistakable signs of current life on a planet beyond Earth. How soon that can happen depends on two unknowns: the prevalence of life in the galaxy and how lucky we get as we take those first, tentative, exploratory steps. Our early planet finding missions ...

   Did NASA find a sign of life on a faraway planet?

   • Artwork: K2-18 b orbits a cool dwarf star shown in red just far enough away for its temperature to support life. Nasa's James Webb Space Telescope may have discovered tentative evidence of a sign of life on a faraway planet. It may have detected a molecule called dimethyl sulphide (DMS). On Earth, at least, this is only produced by life.

   How do you know if there is life on Earth?

   • An imbalance in atmospheric gases also might offer a tell-tale sign of the presence of life. “In Earth’s atmosphere, oxygen and methane are highly reactive with each other,” Kopparapu said. Left to themselves, they would quickly cancel each other out. “They should not be seen together,” he said.
