Astronomers just found the youngest known planet ever
Astronomers have confirmed Elias 2-24 b as the youngest known planet, less than 1 million years old, still forming within its star's dusty disk. This discovery, made using archived observations from the W. M. Keck Observatory, challenges current planet-formation models which struggled to explain previously younger planets. The planet, roughly as massive as Jupiter, was found within a gap in its star's debris disk.
Why it matters
This finding provides a unique opportunity to study planet formation in real-time, potentially revolutionizing our understanding of how planets develop and forcing a re-evaluation of existing astrophysical models. It offers direct insights into the early stages of planetary system evolution.
Astronomers have confirmed the youngest known planet yet, a world less than 1 million years old that is still surrounded by the gas and dust from which it formed.
The planet, called Elias 2-24 b, was identified using observations preserved in NASA-funded archives. It is still orbiting within its young star's dusty disk, giving scientists a rare opportunity to study planet formation while it is still happening.
