Astronomers have confirmed the discovery of the youngest known exoplanet, Elias 2-24 b, which is less than a million years old. This finding provides valuable insights into the early stages of planet formation.
Astronomers have discovered an object in the CT Cha system whose mass is 14 to 24 times greater than that of Jupiter, surrounded by a disk of gas and dust—a rare opportunity to observe the birth of moons around a young planet. The chemical composition of this disk is noticeably different from the material surrounding the star, raising new questions for scientists about how moons and planets form.
