Scientists know that the behaviour of stars can dictate planetary habitability. Research shows that young stars emit powerful radiation that can strip planetary atmospheres away. And without an atmosphere, it's extremely unlikely that life could exist. But of course stars aren't all the same. Their masses dictate what type of star they'll be, how long they'll shine, and how they'll meet their end. Along the way, their masses also dictate how much radiation they emit. Powerful x-ray radiation can strip planetary atmospheres away, dooming its prospects for hosting life. Stars like our Sun are under increasing scrutiny in the search for habitable exoplanets. The ESA's Plato (PLAnetary Transits and Oscillations of stars) mission specifically targets Sun-like stars and the terrestrial planets that orbit them. The tentative Habitable Worlds Observatory (HWO) is also aimed at Sun-like stars and terrestrial worlds. Why the focus on Sun-like stars?…
