For three decades, astronomers mapped distant worlds through the lens of stars most like our own Sun, and a seemingly universal pattern took shape. Now, a McMaster University study using NASA's TESS satellite has revealed that this pattern was never universal at all — only local. Around red dwarfs, the galaxy's most numerous stars, the gas-shrouded sub-Neptunes that define planetary surveys around Sun-like stars are nearly absent, replaced by rocky, water-rich super-Earths. The cosmos, it turns out, builds its worlds differently depending on the star doing the building.
