ALMA Campaign Provides Unprecedented Views of the Birth of Planets. ALMA‘s first large-scale, high-resolution survey of protoplanetary disks. Fantastic pictures. Because what is astronomy if not fantastic pictures?
We're looking at somebody's future right there. In a few billion years they may be sitting on a planet formed out of one of those disks, probably having no idea that we existed and bore witness to their beginnings. We will be long gone or transformed unrecognizably. I wish them the best.

The first of these was HL Tau, imaged by ALMA in 2014. That image pretty much started the planetary disk gold rush and set the bar - it's such a glorious image that it is hard to grasp that it's actual data, not an artist's conception.
With this DSHARP sample, I guess now we see the diversity of such systems.
