Young planet's atmosphere challenges traditional formation models
Los Angeles CA (SPX) Dec 26, 2024 Scientists have long believed that planets forming within a swirling disk of gas and dust should closely resemble the composition of their birthplace. However, new research led by Northwestern University astrophysicists suggests this assumption may be oversimplified. The study, published in Astrophysical Journal Letters, analyzed a young exoplanet and its natal disk, revealing unexpected differences in gas composition. The findings could reshape how scientists understand planetary formation proces ... read more |
