Los investigadores utilizarán el telescopio espacial James Webb de la NASA para la encuesta 17 de los 20 discos protoplanetarios cercanos observados por la matriz de milímetro/submilímetro Atacama de Chile (ALMA) en 2018 por sus subestructuras de disco en el proyecto de resolución angular alta (DSHARP). Alma entregó excelentes datos sobre los discos externos, pero Webb detallará los discos internos entregando espectros, que difunden la luz en un arco iris, revelando las composiciones químicas de cada objeto.

| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
| About The Data | |
| Data Description |
|
| Instrument | The science instrument used to produce the data. |
| Exposure Dates | The date(s) that the telescope made its observations and the total exposure time. |
