A new study published in the Astrophysical Journal Letters suggests that planets like Earth, including those with water, could form even in the harshest known star-forming environments. These environments, drenched in intense ultraviolet radiation from massive stars, were previously thought to be too hostile for planet formation. The study, led ... [more]
