ALMA's Survey of Protoplanetary Disks

 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.

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
