In case you were wondering, here’s what your star was up to a few days ago, on March 13. A beautiful image by Mark Johnston.

An international team captured an unprecedented view of gas streamers flowing into a forming high-mass star. Thanks to ALMA’s sharp vision, the team detected clear signs of both rotation and inward motion in the gas. alma-telescope.jp/en/news/stream…
