Astronomers Discover Youngest Known Planet Still Forming in Dust

The discovery, led by doctoral candidate Andrea Bernardi of Universidad Diego Portales, utilized archival data from the W. M. Keck Observatory in Hawaii. By employing a coronagraph to mask the intense glare of the host star, researchers successfully pinpointed the planet within a distinct gap in the surrounding debris disk—a telltale sign that the object is carving its own path through the primordial material.

Elias 2-24 b possesses a mass comparable to Jupiter, yet its extreme youth complicates traditional detection methods. Because standard transit techniques rely on a planet passing between its star and Earth, they often fail to spot younger worlds buried in thick, opaque clouds of dust and ice. Co-author Lucas Cieza noted that current formation models struggle to account for this discovery, as previous records of the youngest planets involved objects at least 5 million years old. This find suggests that key processes governing planetary birth are missing from contemporary theories, highlighting a significant blind spot in the observation of galactic evolution.
