… May Face Oxygen Loss ""If we want to find an exoplanet that can develop and sustain life, we must figure out which stars make the best parents. We're coming closer to understanding what kind of parent stars we need," Dr. Airapetian said. To determine a star's habitable zone, astronomers have traditionally considered how much heat and light the star emits. Stars more massive than the Sun produce more heat and light, so the habitable zone must be farther out. Smaller, cooler stars yield close-in habitable zones. But along with heat and visible light, stars emit X-ray and UV radiation, and produce stellar eruptions such as flares and coronal mass ejections — collectively called space weather…"
