MinuteBrief reports that Elias 2-24 b is the youngest known exoplanet, at under a million years old. Another post describes it as a Jupiter-mass planet about 450 light-years away, still growing inside its star’s disk of gas and dust. That account says researchers used archival Keck images from 2018 and 2020 to establish that it was a planet rather than a dust clump or an imaging artifact.
