Astronomers confirm a newly identified planet, Elias 2-24 b, as the youngest known world, estimated to be less than a million years old. The finding is based on archived observations supported by NASA, which allow researchers to detect a young planet still embedded in the material around its forming star.
The planet is described as “baby” because it is still orbiting within its natal disk of dust and gas—the same disk from which planets form. This placement suggests the planet is forming or has formed only extremely recently, providing a test for how quickly planet formation can proceed.
Across outlets, the core elements of the report are consistent: the planet’s extremely young age, its name (Elias 2-24 b), and the interpretation that it remains in its birth disk. The coverage emphasizes the use of archival data and notes that existing planet-formation models may have difficulty explaining prior records for the youngest known planets, given how early such worlds appear to exist.
