This final movie shows how NGC 1904 evolves in the Milky Way. The left panel shows a zoomed-out view centered on the Milky Way and the right panel shows a zoomed-in view centered on the globular cluster. The dumbbell morphology we see on the sky comes from the last stripping episode. 3/3 🔭

Paper day! Petra Awad led this nice paper (arxiv.org/abs/2411.08991) on the outskirts of NGC 1261 and NGC 1904. NGC 1904 has two jets of stars stripped at its most recent pericenter with the Milky Way. This pericenter was only ~0.12 kpc which led to this strong stripping event. 1/3 🔭
