A few days ago, astronomers using the Atacama Large Millimeter Array telescope (or, ALMA) released this astonishing image:

This is an image of a protoplanetary disk — the ring of gas and dust that astronomers think surrounds most forming stars (or, protostars). The image amazes for a few reasons. It is the first image to show the detailed concentric rings indicative of planet formation in a protoplanetary disk. This visualization of real-time planet formation looks startlingly like artistic renderings of protoplanetary disks often used in interpreting fuzzy astronomical images.

Even more interesting, perhaps, is that the protostar, HL Taurus (often referred to as HL Tau)…
