ALMA Captures Sharpest Views Yet of Exoplanetary Debris Disks
This ARKS gallery of faint debris disks reveals details about their shape: belts with multiple rings, wide smooth halos, sharp edges, and unexpected arcs and clumps, which hint at the presence of planets shaping these disks; and chemical make-up: the amber colors highlight the location and abundance of the dust in the 24 disks surveyed, while the blue their carbon monoxide gas location and abundance in the six gas-rich disks.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have produced the unprecedented high-resolution images of 24 debris disks -- the dusty belts left after planets finish forming -- revealing the dynamic, transitional phase between planet birth and mature exoplanetary systems.
