#ALMA has been in scientific operations for almost 15 years. As of the beginning of February 2026, ALMA had observed 3933 independent coordinates. Here is a collection of ALMAs observations of circumstellar #disks with substructures in dust continuum emission, available in the literature. Each panel is 400 au in size, and the disks are scaled based on the #Gaia DR3 parallax, ranging from largest to smallest continuum disk from top to bottom. #astronomy https://astrobiology.com/2026/06/an-archival-summary-15-years-of-alma-observations-on-disks-and-planet-formation.html Paper by Kurtovic et al.
