The star (center) is surrounded by a clumpy envelope of material in its immediate vicinity. A series of arcs 6тАУ7 arcminutes to the left of the star is material ejected from Betelgeuse as it evolved into a red supergiant star, shaped by its bow shock interaction with the interstellar medium. A faint linear bar of dust is illuminated at a distance of 9 arcminutes and may represent a dusty filament connected to the local galactic magnetic field or the edge of an interstellar cloud. If so, then BetelgeuseтАЩs motion across the sky implies that the arcs will hit the wall in 5,000 years time, with the star colliding with the wall 12,500 years later. // Credit: ESA/Herschel/PACS/L.
