ALMA’s Survey of Protoplanetary Disks
The researchers will use NASA’s James Webb Space Telescope to survey 17 of the 20 nearby protoplanetary disks observed by Chile’s Atacama Large Millimeter/submillimeter Array (ALMA) in 2018 for its Disk Substructures at High Angular Resolution Project (DSHARP). ALMA delivered excellent data about the outer disks, but Webb will detail the inner disks by delivering spectra, which spread light out into a rainbow, revealing the chemical compositions of each object.

Simulated Spectrum of a Protoplanetary Disk
The James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) will deliver incredibly rich information about the molecules that are present in the inner disks of still-forming planetary systems (known as protoplanetary disks). This simulated spectrum, which produces a detailed...
