Such views suggest that tiny galaxies in the early universe played a crucial role in cosmic reionization — when
ultraviolet radiation stripped electrons from hydrogen atoms in the cosmos.

They're much closer to their sun than we are to ours, so TRAPPIST - 1's
ultraviolet radiation would likely
strip away most of their atmospheres.
Ultraviolet radiation could
strip not only the water vapor from a habitable M dwarf planet, but also the oxygen and nitrogen in just tens of millions of years, astrophysicist Vladimir Airapetian of NASA's Goddard Space Flight Center in Greenbelt, Md., and colleagues suggested in the February 10 Astrophysical Journal Letters.
Furthermore, KELT - 9b receives ~ 700 times more extreme
ultraviolet radiation (wavelengths shorter than 91.2 nanometers) than WASP - 33b, leading to a predicted range of mass - loss rates that could leave the planet largely
stripped of its envelope during the main - sequence lifetime of the host star.
