ALMA + Japan: Hi-Def Imaging of Spiral Gas Arms from Twin Baby Stars (w/video)

New out of Japan, this high def imaging was possible from the "ATERUI” supercomputer at the National Astronomical Observatory of Japan (NAOJ).

This data is from "L1551 NE" in the Taurus Constellation.

ResearchBlogging.org Quoting NAOJ: "These observational results unveil, for the first time, the mechanism of the birth and growth of binary stars, which are ubiquitous throughout the universe."

We know that about half the the stars out there (with sizes close to that of our sun) are binary systems.  However, for a long time we've been lacking information on how they develop, since it's not been easy to get a whole lot of data from surrounding scattered mass that's so damned far away!  Congrats to all involved!
