Researchers: There Are Cold Planets Throughout Our Galaxy

They report that there are even cold planets in the Galactic bulge, where it was not certain they would exist

Researchers from Osaka University, using gravitational microlensing, have determined that there are cold planets throughout our galaxy. Cold planets would have average temperatures below the freezing point. The results show that the planetary distribution is not strongly dependent on the distance from the Galactic center. Instead, cold planets orbiting far from their stars seem to exist universally in the Milky Way. This includes the Galactic bulge, which has a very different environment to the solar neighborhood, and where the presence of planets has long been uncertain. “Stars in the bulge region are older and are located much closer to each other than stars in the solar neighborhood,” explains lead author of the study Naoki Koshimoto. “Our finding that planets reside…
