"Alien life-forms could glow in spectacular reds, blues and greens to shield themselves from stellar bursts of ultraviolet (UV) radiation. And that glowing light could be how we find them, according to a new study."
Most of the exoplanets we think are the most habitable, orbit red dwarfs, for instance Proxima Centauri or TRAPPIST-1.
However, if we don’t find aliens life there, the ones who seek for alien life have a great problem.
Glowing is not too surprising, Here on earth, some corrals protect themselves by glowing, says lead author Jack O'Malley-James, a research associate at the Cornell Center for Astrophysics and Planetary Science of the new research, posted in the journal Monthly Notices of the Royal Astronomical Society.
