​Who is Indian-origin Dr Nikku Madhusudhan, the scientist who found evidence of life 120 light-years away from Earth

Dr. Nikku Madhusudhan, an Indian-origin astrophysicist, leads a team that has found compelling evidence of biological activity on exoplanet K2-18b, 120 light-years away. Using the James Webb Space Telescope, they detected dimethyl sulfide (DMS), a molecule only produced by living organisms on Earth. This revolutionary discovery marks the first potential biosignature detection on a habitable planet.
