Highlights

Keck Observatory imaged a planet-forming disk around HD 34282
Bright clumps and gaps suggest planets are forming
Only a few young planets have been directly seen so far

The Keck Observatory astronomers have made the nearest examination of the dusty areas where planets are created. Their target, HD 34282, is a recently formed star approximately 400 light-years distant that is encircled by a dense halo of dust and gas, a transition disk that is thought to be cut by forming planets. The new infrared images showed clumpy shapes and brightness differences within the disk of HD 34282, which indicated that planets were undergoing their formation.

Probing a Planet-Forming Disk

According to the study, the researchers wrote that with the Keck NIRC2 camera equipped with adaptive optics and a special aperture mask, the team was able to image the inner disk of HD 34282 in greater detail than it had ever been.

They broke open an inner dusty envelope and an outer disk (with a gap of about 40 AUs between them), a tell-tale indicator that planets are possibly forming there. The picture is of clumpy dust and luminous areas of the disk, which are taken to be the accumulated material forming new worlds.

Rarity and Significance of the Findings

Finding infant planets is notoriously hard. So far, only two-PDS 70 b and c-have been directly imaged inside their disks, making HD 34282's clues very valuable. Other systems, such as HL Tau, show rings and gaps hinting at hidden planets.

HD 34282's new data refine this picture: even without a planet spotted, the gap and clumps in this disk reveal where a baby world could lie. The team will press on, surveying more young stars and using future tools-like Keck's upcoming SCALES imager-to unveil these worlds-in-formation.
